[0004] Conventional athletic footwear comprises two main components: the upper and the sole structure. The upper provides coverage for the foot, securely housing and positioning it relative to the sole structure. Additionally, the upper can have a configuration that protects the foot and provides breathability, keeping the foot cool and wicking away sweat. The sole structure is attached to the underside of the upper and is typically located between the foot and any contact surfaces. Besides reducing ground reaction forces and absorbing energy, the sole structure also provides traction and controls potentially harmful foot movements, such as overpronation.

[0005] The upper forms a cavity within the footwear to accommodate the foot. This cavity has a general shape to the foot and an entrance at the ankle opening. Therefore, the upper extends over the instep and toe areas of the foot, along the medial and lateral sides of the foot, and around the heel area. A lacing system is typically integrated into the upper to allow the user to selectively change the size of the ankle opening and to modify certain dimensions of the upper, particularly the girth, to accommodate different foot proportions. Additionally, the upper may include a tongue that extends below the lacing system to enhance footwear comfort (e.g., to adjust the pressure applied to the foot by the laces). The upper may also include a heel stabilizer to limit or control heel movement.

[0006] At least some aspects of this technology may include the structures described in U.S. Patent Nos. 11,206,896 B2 and 11,234,485 B2 and / or may be used in systems of the type described therein, which are incorporated herein by reference in their entirety. Summary of the Invention

[0033] In the following description of various examples of footwear structures and components according to the present technology, reference is made to the accompanying drawings, which form part of the present technology, and the drawings illustrate various example structures and environments in which aspects of the present technology can be practiced. It should be understood that other structures and environments can be utilized, and structural and functional modifications can be made to the specifically described structures and methods without departing from the scope of this disclosure.

[0034] As used herein, the term "footwear" means any type of clothing worn on the feet, and includes, but is not limited to: all types of shoes, boots, athletic shoes, sandals, flip-flops, slippers, slippers, sleepwear, casual shoes, athletic footwear (such as golf shoes, tennis shoes, baseball shoes, football shoes, ski boots, basketball shoes, cross-training shoes, dance shoes, etc.). As used herein, the term "foot housing" means any device in which a user places at least a portion of his or her foot. In addition to various types of "footwear," foot housings include, but are not limited to: straps and other devices for securing the foot to skis, cross-country skis, water skis, snowboards, etc.; straps, clamps, or other devices for securing the foot to pedals used with bicycles, sports equipment, etc.; straps, clamps, or other devices for housing the foot during video games or other games. A “foot housing device” may include one or more “foot covering members” (e.g., similar to footwear upper components) that facilitate the positioning of the foot relative to other components or structures; and one or more “foot support members” (e.g., similar to footwear sole structural components) that support at least one or more portions of the sole surface of the user’s foot. A “foot support member” may include components for and / or as a midsole and / or outsole in footwear articles (or components that provide a corresponding function in non-footwear foot housing devices).

[0035] The "longitudinal length" parameter L describes various structures and parameters of foot support systems, sole structures, and / or footwear products. Note Figure 2A The longitudinal length L can be found under unloaded conditions (e.g., no weight is applied to the footwear article 250 or sole structure 200 except for the weight of other parts of the footwear article 250 or sole structure 200) when the footwear article 250 or sole structure 200 is oriented on its ground-facing surface (e.g., on its sole structure 200) with a horizontal support surface S. Once so oriented, a parallel vertical plane VP perpendicular to the horizontal support surface S is oriented to contact the rearmost heel (RH) position and the foremost toe (FT) position of the footwear article 250 (or upper 202, or sole structure 200, or another part of interest). The parallel vertical planes VP should be oriented to face each other, for example, extending to... Figure 2A In the page and from Figure 2AThe pages extend outwards and are as far apart as possible from each other, while still contacting the rearmost heel RH and the foremost toe FT positions. The direct distance between these vertical planes VP corresponds to the longitudinal length L of the footwear article 250 (or upper, or sole structure 200, or another component of interest). The positions of various footwear features and / or components are described in this specification based on their respective positions along the longitudinal length L as measured forward from the rearmost heel vertical plane VP. Along the longitudinal length L, the rearmost heel position is located at position 0L, and the foremost toe position is located at position 1L. Intermediate positions along the longitudinal length L are indicated by fractional positions (e.g., 0.25L) along the longitudinal length L measured forward from the rearmost heel vertical plane VP. As used herein, the term "parallel plane" is a plane oriented parallel to the vertical plane VP. These parallel planes may intersect the longitudinal length L or the longitudinal direction somewhere between P=0L and P=1.0L. Note Figure 2A This includes example parallel plane position indicators at 0.16L, 0.26, 0.35L, and 0.46L.

[0036] As used herein, the term "rearward" refers to the heel area of ​​the footwear article (or its components), and as used herein, the term "forward" refers to the forefoot or forefoot toe area of ​​the footwear article (or its components). Unless otherwise defined, the terms "heel" or "heel area" refer to the area defined by parallel planes at 0L and 0.3L, the terms "midfoot" or "arch" refer to the area defined by parallel planes at 0.3L and 0.6L, and the term "forefoot" refers to the area defined by parallel planes at 0.6L and 1.0L. Furthermore, the term "lateral" refers to the "little toe" side or outer edge of the footwear article or its components (e.g., upper, sole structure, etc.), and the term "medial" refers to the "big toe" side or inner edge of the footwear article or its components (e.g., upper, sole structure, etc.).

[0037] As used herein, the term "port" includes any opening in a component through which fluid (e.g., gas) can enter or exit the component. Some "ports" may include one or more hardware components or other structures to which a fluid line can be connected. In some instances of this technology, a fluid line may be connected to a "port" of another component via adhesives, by thermofusion or welding (also referred to herein as "fusion technology"), by mechanical connectors, etc. In example structures where a fluid line is integrally formed with another part (such as a pump, foot support bladder, storage chamber component (e.g., storage chamber bladder), or other fluid source component), a "port" can be considered as the location where the size of the internal chamber changes from a relatively small fluid tube size to a relatively large and more open volume (e.g., a change in cross-sectional area).

[0038] This application and / or its claims use terms such as "first," "second," "third," etc., to identify certain components and / or features related to this technology. The use of these terms is merely for convenience, such as to help maintain distinction between components and / or features of a particular structure. The use of these terms should not be construed as requiring a specific order or arrangement of the components and / or features in question. Furthermore, the use of these specific terms for a particular structure in the specification does not require the use of the same terms in the claims to refer to the same parts (e.g., a component or feature referred to as "third" in the specification may correspond to any numerical adjective used for that component or feature in the claims). I. General Description of Various Aspects of This Technology

[0039] As described above, various aspects of this technology relate to fluid systems, foot support systems, sole structures, footwear articles, and / or other foot housing devices, such as the types described and / or claimed below and / or illustrated in the accompanying drawings. Such fluid systems, foot support systems, sole structures, footwear articles, and / or other foot housing devices may include any one or more structures, portions, features, characteristics, and / or combinations of structures, portions, features, and / or characteristics of the examples described and / or claimed below and / or illustrated in the accompanying drawings.

[0040] As some more specific examples, aspects of this technology relate to fluid systems, foot support systems, sole structures, and / or footwear articles, including: (a) a foot support bladder (e.g., including a first port and a second port); (b) a fluid reservoir (e.g., including a third port); (c) a pump (e.g., a foot activation pump) including an inlet and an outlet, the outlet supplying fluid to the fluid reservoir; (d) a first fluid line fluidly communicating the foot support bladder to the pump inlet; and (e) a second fluid line fluidly communicating the foot support bladder to the fluid reservoir. In some examples of this aspect of the technology, the pump and the fluid reservoir may comprise multiple portions of a single component (e.g., portions of a single fluid filling bladder and / or fluid source component). Such fluid systems, foot support systems, sole structures, and / or footwear articles may also include one or more of the following: (i) fluid line support members (e.g., for supporting one or both of the first fluid line and / or the second fluid line); (ii) switches (e.g., for changing at least one of the first fluid line and / or the second fluid line between an open configuration and a closed configuration); and / or (iii) electronically controlled switches or valves, optionally in electronic communication with a computing system to receive user input (e.g., for changing at least one of the first fluid line and / or the second fluid line between an open configuration and a closed configuration). Such foot support systems, sole structures, and / or footwear articles may also include one or more of the following: (i) one or more midsole components (e.g., above and / or below the foot support bladder, between the foot support bladder and the fluid reservoir, at least partially separating the foot support bladder and the fluid reservoir, etc.); (ii) one or more outsole components (e.g., forming the bottom outer surface of the foot support system, sole structure, and / or footwear article (e.g., ground contact surface)); and / or (iii) one or more pump activator components (e.g., in the heel and / or forefoot area), etc.

[0041] Other examples and aspects of this technology relate to fluid systems, foot support systems, sole structures, and / or footwear articles, comprising: (a) a foot support bladder (e.g., including a first port and a second port); (b) a fluid reservoir (e.g., including a third port); (c) a pump (e.g., a foot activation pump) including an inlet and an outlet, the outlet supplying fluid to the foot support bladder; (d) a first fluid line fluidly communicating the fluid reservoir to the pump inlet; and (e) a second fluid line fluidly communicating the foot support bladder to the fluid reservoir. In some examples of this aspect of the technology, the pump and the fluid reservoir may comprise multiple portions of a single component (e.g., portions of a single fluid-filled bladder and / or fluid source component). Such fluid systems, foot support systems, sole structures, and / or footwear articles may also include one or more of the following: (i) fluid line support members (e.g., for supporting one or both of the first fluid line and / or the second fluid line); (ii) switches (e.g., for changing at least one of the first fluid line and / or the second fluid line between an open configuration and a closed configuration); and / or (iii) electronically controlled switches or valves, optionally in electronic communication with a computing system to receive user input (e.g., for changing at least one of the first fluid line and / or the second fluid line between an open configuration and a closed configuration). Such foot support systems, sole structures, and / or footwear articles may also include one or more of the following: (i) one or more midsole components (e.g., above and / or below the foot support bladder, between the foot support bladder and the fluid reservoir, at least partially separating the foot support bladder and the fluid reservoir, etc.); (ii) one or more outsole components (e.g., forming the bottom outer surface of the foot support system, sole structure, and / or footwear article (e.g., ground contact surface)); and / or (iii) one or more pump activator components (e.g., in the heel and / or forefoot area), etc. Additionally or alternatively, the fluid system, foot support system, sole structure, and / or footwear article of this aspect of the present technology may be altered in height as the fluid system, foot support system, sole structure, and / or footwear article switch between a higher pressure foot support configuration (e.g., a switch closes the second fluid line) and a lower pressure foot support configuration (e.g., a switch opens the second fluid line). (e.g., increasing the height dimension of one or more of the fluid storage chamber, sole structure, and / or footwear article.)

[0042] In view of the general description of features, aspects, structures, processes and arrangements of certain examples according to the present technology provided above, the following is a more detailed description of specific examples of fluid systems, foot support systems, sole structures, footwear articles and methods according to the present technology. II. Detailed description of exemplary fluid systems, foot support systems, sole structures, footwear products, and other components / features based on this technology.

[0043] Referring to the accompanying drawings and the following discussion, various examples of fluid systems, foot support systems, sole structures, and / or footwear articles according to various aspects of the present technology are described.

[0044] Figure 1A and Figure 1B A fluid system 100 according to at least some aspects of the present technology is schematically illustrated. This fluid system 100 can be incorporated into foot support systems (e.g., sole structures) and / or footwear articles in various ways, such as as described in more detail below. This example fluid system 100 is a “closed system,” for example, the fluid system 100 has a fixed amount (e.g., mass) of fluid (e.g., gas, such as air or other gases, including gases commonly known and used in foot support bladder systems) sealed therein, and the fluid system 100 does not introduce new fluid from the external environment and does not discharge fluid to the external environment. However, alternatively, at least some aspects of the present technology can be used for “open” fluid systems, such as fluid systems that introduce air (or other gases) from the external environment and / or discharge air (or other gases) to the external environment to change the foot support pressure in the foot support bladder.

[0045] Figure 1A A fluid system 100 in a "low-pressure" foot support configuration is shown, and Figure 1B A fluid system 100 in a "high-pressure" foot support configuration is shown. As illustrated in these figures, the fluid system 100 includes a foot support bladder 400 and a fluid reservoir 500 (which may include a fluid-filled bladder or other fluid container). A pump 550 (e.g., a foot-activated pump, such as a ball-type pump) moves fluid from the foot support bladder 400 to the fluid reservoir 500. When a switching element 900 is closed, as... Figure 1A As shown, pump 550 removes fluid from foot support bladder 400 and moves it into fluid reservoir 500 to position foot support bladder 400 in a lower-pressure foot support configuration. Specifically, compression of the internal chamber 550C of pump 550 (e.g., in response to a user's footstep) forces fluid toward pump outlet 552, while check valve 114 prevents fluid from flowing from pump 550 into foot support bladder 400 via fluid line 402. As long as the pressure generated by the compression of pump 550 is greater than the pressure in fluid reservoir 500, fluid will move through fluid line 502, through check valve 118, and into the internal chamber 500C of fluid reservoir 500 (e.g., through reservoir port 510). Alternatively, fluid line 502 can be omitted (or fluid line 502 can be very short, for example, as discussed below). Figure 5C and Figure 5DAs shown), the pump outlet 552 supplies fluid substantially directly to the check valve 118, and / or the check valve 118 can be directly connected to the storage chamber port 510 and / or the internal chamber 500C of the fluid storage chamber 500. When the internal chamber 550C of the pump 550 expands again (e.g., when the user lifts his / her foot off the contact surface), fluid is drawn out of the internal chamber 400C of the foot support bladder 400, enters the fluid line 402 through the bladder port 410, and enters the internal chamber 550C of the pump 550 (via the fluid source port 554A, the fluid source line 402A, the check valve 114, and the pump inlet 554). Figure 1A (and Figure 1B The dotted-dash line marked 520 in the diagram outlines the components that can be included within the fluid source component 520. The following section combines... Figures 5A to 5D Let's discuss this in more detail.

[0046] exist Figure 1A In the configuration shown: (i) a closed switch 900 prevents fluid from moving from the fluid reservoir 500 to the foot support bladder 400 via the fluid line 504, and (ii) a check valve 118 prevents fluid from flowing from the fluid reservoir 500 to the pump 550 via the fluid line 502. Therefore, in this configuration, over time (e.g., after one or more foot cycles), by activating the pump 550, fluid moves from the foot support bladder 400 to the fluid reservoir 500, thereby placing the foot support bladder 400 at a lower pressure than the fluid reservoir 500. This action and configuration place the example foot support bladder 400 at a lower pressure in this foot support configuration.

[0047] When the switch component 900 is opened, such as Figure 1B As shown, this opens the fluid line 504 and allows fluid to flow from the fluid reservoir 500 to the foot support bladder 400 via the fluid line 504 (e.g., fluid flows between the reservoir port 512 and the bladder port 412 via the fluid line 504). This switching action equalizes the pressure in the internal chamber 400C of the foot support bladder 400 and the internal chamber 500C of the fluid reservoir 500, for example, thereby increasing the pressure in the internal chamber 400C and decreasing the pressure in the internal chamber 500C. This action and configuration place this example foot support bladder 400 in a higher pressure foot support configuration. In use, when the user... Figure 1B In the configuration shown, when the pump 550 is stepped on, the fluid will flow freely around the loop (from the pump 550, through the fluid line 502, into the fluid storage chamber 500, through the fluid line 504, into the foot support bladder 400, through the fluid line 402 and back into the pump 550).

[0048] Now we will combine Figures 2A to 16CExample sole structure 200, footwear article 250 and / or components thereof, comprising at least a plurality of portions of a fluid system 100 and / or forming at least a plurality of portions of the fluid system 100, are described according to various aspects of the present technology.

In the example shown, the first midsole component 300 comprises a single polymer foam component (e.g., made of ethylene-vinyl acetate (EVA) foam, polyurethane foam, etc.), but other constructions and / or materials (e.g., rubber, other elastomers, thermoplastic polyurethane, etc.) may also be used. Alternatively, if desired, the first midsole component 300 may be made of two or more components, including: one or more polymer foam midsole components, one or more mechanical damping components, one or more fluid-filled bladders (e.g., in addition to the foot support bladder 400 described in more detail below), one or more heel components, one or more forefoot components, one or more arch support portions, etc.

[0052] The first midsole component 300 includes an upward-facing surface 300U and a ground-facing surface 300G. An outer surface 300L and an inner surface 300M extend along both sides of the first midsole component 300 between the upward-facing surface 300U and the ground-facing surface 300G. These side surfaces 300L and / or 300M can have any desired size, shape, thickness, texture (e.g., including smooth walls, textured walls, combinations, etc.), decorative features, etc. Figures 3A to 3DThe lines and grooves shown in (and other figures) represent an example of a decorative design for the wall surface. The first midsole component 300 also includes a forefoot tip 300T and a heel end 300H. Thus, the first midsole component 300 in this illustration extends through and lies beneath and / or supports all or substantially all (e.g., at least 90% or even at least 95% of the surface area) of the wearer's foot and / or the entire or substantially all (although other sizes are also possible) of the sole surface of the wearer's foot.

[0053] Figure 3A , Figure 3C and Figure 3D The illustration shows that the first midsole component 300 includes a receiving portion 310 (e.g., a notch with a notch) formed in a sidewall (e.g., in the outer sidewall of the illustrated example). Alternatively, such a receiving portion 310 may be formed in the inner sidewall, the heel wall, or other locations on the first midsole component 300, if desired. The receiving portion 310 is provided to receive and accommodate the support component 600, the switching component 900, and other components of the fluid system 100, which will be described in more detail below.

[0054] In some embodiments of this technology, the rear wall 310R of the receiving portion 310 may be located in the first midsole component 300, the sole structure 200, and / or the footwear article 250: (a) behind the parallel plane at 0.5L, and in some embodiments, behind the parallel plane at 0.45L, 0.42L, or 0.4L, and / or (b) in front of the parallel plane at 0.25L, and in some embodiments, in front of the parallel plane at 0.28L, 0.3L, or 0.32L. See also Figure 2A Additionally or alternatively, the front wall 310F of the receiving portion 310 may be located in the first midsole component 300, the sole structure 200, and / or the footwear article 250: (a) behind the parallel plane at 0.6L, and in some instances behind the parallel planes at 0.55L, 0.52L, or 0.5L, and / or (b) in front of the parallel plane at 0.35L, and in some instances in front of the parallel plane at 0.38L, 0.4L, or 0.42L. Figure 2A As shown, in this illustrated example, the rear wall 310R is located at approximately 0.35L, and the front wall 310F is located at approximately 0.46L (e.g., at least partially or completely within the midfoot area of ​​the sole structure 200 and / or footwear article 250). The receiving edge 310E extends between the front wall 310F and the rear wall 310R. See Figure 3A , Figure 3C and Figure 3D Despite Figure 3A , Figure 3C and Figure 3DThe notch or notch is shown as a relatively rectangular shape, but the receiving part 310 can have any desired size and / or shape.

[0055] In this example, the first midsole component 300 is at least partially sandwiched between the foot support bladder 400 and the fluid source component 520 in the final sole structure 200. Therefore, while the upward-facing surface 300U of the first midsole component 300 can be any desired shape, including flat and / or smooth profiles, in situations such as... Figure 3C In the example illustrated, the size and shape of the upward-facing surface 300U are designed to accommodate and retain the foot support bladder 400. Similarly, the ground-facing surface 300G of the first midsole component 300 can be of any desired shape, including flat and / or smooth contours. In the example illustrated, as... Figure 3D As shown, the ground-facing surface 300G includes one or more of the following: (a) a base surface 312 to which a portion of the support member 600 is attached (e.g., base region 602, see...). Figure 10D (a) a fluid line support area 314 for engaging and / or accommodating at least a portion of the fluid source line 402A; (b) a valve support area 316 for engaging and / or accommodating at least a portion of the check valve 114; (c) a pump support area 318 (e.g., a circular recess) for engaging and / or accommodating at least a portion of the pump 550; (e) a valve support area 320 for engaging and / or accommodating at least a portion of the check valve 118; (f) one or more protrusions 322 (e.g., in the midfoot and / or forefoot areas) configured to engage corresponding recesses on the fluid reservoir 500 (or other portions of the fluid source component 520); and / or (g) a recess 324 for accommodating at least a portion of the upward-facing surface 500U of the fluid reservoir 500 and / or at least a portion of the entire fluid source component 520.

[0056] Figures 4A to 4D Top, lateral, bottom, and medial views of a foot support bladder 400, which can be used according to some examples of this technology, are provided. The foot support bladder 400 can be formed from a thermoplastic elastomer material (e.g., two sheets, a folded sheet, etc.) in a manner conventionally known and used in the footwear industry. The illustrated example foot support bladder 400 includes an upward-facing surface 400U, a ground-facing surface 400G, and a sealed peripheral seam 400S, wherein the sheets forming surfaces 400U and 400G are welded, heat-sealed, and / or otherwise joined together. An internal chamber 400C (attached above) Figure 1A and Figure 1BThe described portion is defined between the upward-facing surface 400U and the ground-facing surface 400G and inside the sealed peripheral joint 400S. One or more internal joints or welds 404 may be provided (in... Figures 4A to 4D One example is shown, for instance, to control the shape of the foot support bladder 400 when inflated.

[0057] According to this technology, the foot support bladder 400 can have various shapes and / or sizes. In the example illustrated, the foot support bladder 400 includes: (i) a heel region 400H (e.g., supporting at least 50% of the surface area of ​​the wearer's heel), (ii) a forefoot region 400F (e.g., supporting at least 50% of the surface area of ​​the wearer's forefoot), and (iii) a midfoot connection portion 400M, which narrows compared to the heel region 400H and the forefoot region 400F and is offset towards the outside of the foot support bladder 400. The internal chamber 400C of the example foot support bladder 400 illustrated extends continuously between the heel region 400H and the forefoot region 400F through the midfoot connection portion 400M. In fact, the internal chamber 400C of the example foot support bladder 400 illustrated extends continuously throughout the entire foot support bladder 400 (except at any internal welds 404 and / or recesses), such that the entire internal chamber 400C is in open fluid communication.

[0058] Figures 4A to 4C The example foot support bladder 400 is also illustrated, including a first bladder port 410 that connects to a fluid line 402 that supplies fluid from the internal chamber 400C of the foot support bladder 400 to a pump 550. Additionally, the example foot support bladder 400 includes a second bladder port 412 that connects to a fluid line 504 that extends between the internal chamber 500C of a fluid reservoir 500 and the internal chamber 400C of the foot support bladder 400, connecting the internal chamber 500C of the fluid reservoir 500 to the internal chamber 400C of the foot support bladder 400. In the example illustrated, the first bladder port 410 and the second bladder port 412 are located on the side edge of the foot support bladder 400 (e.g., adjacent to each other at the outer edge in the midfoot connection portion 400M), and they may be positioned at or within the receiving portion 310 of the first midsole component 300 in the finally assembled sole structure 200.

[0059] Figures 5A to 5DAn exterior view, an interior view, a top view, and a bottom view are provided for a fluid source component 520 (e.g., including a combined pump 550 and a fluid reservoir 500) that can be used according to some examples of the present technology. Any desired type of fluid source component 520 (e.g., a fluid container) can be used in examples of the present technology. However, in the example illustrated, the fluid source component 520 constitutes a fluid-filled bladder, for example, formed from a thermoplastic elastomer material (e.g., two sheets, a folded sheet, etc.) in a manner conventionally known and used in the footwear industry. The example fluid source component 520 illustrated includes an upward-facing surface 500U, a ground-facing surface 500G, and a sealed peripheral seam 500S, wherein the sheets forming surfaces 500U and 500G are welded, heat-sealed, and / or otherwise joined together. An internal chamber 500C (combined above) Figure 1A and Figure 1B The described portion is defined between the upward-facing surface 500U and the ground-facing surface 500G and inside the sealed peripheral joint 500S. One or more internal joints, welds, or recesses 522 may be provided, for example, to control the shape of the fluid source component 520 and / or to form additional components within the fluid source component 520, which will be described in more detail below.

[0060] According to the present technology, the fluid source component 520 can have various shapes and / or sizes. In the example illustrated, the fluid source component 520 includes: (i) a heel region 500H (e.g., which supports at least 50% (and in some embodiments, at least 75%) of the surface area of ​​the wearer's heel), (ii) a forefoot region 500F (e.g., which supports at least 15% (and in some embodiments, at least 20% or at least 25%) of the surface area of ​​the wearer's forefoot), and (iii) a midfoot portion 500M between the heel region 500H and the forefoot region 500F. The internal chamber of the example fluid source component 520 illustrated extends continuously through the midfoot portion 500M between the heel region 500H and the forefoot region 500F. In fact, the internal chamber of the example fluid source component 520 illustrated extends continuously throughout the fluid source component 520 (except at any internal welds 520W and / or recesses 522).

[0061] The entire structure of the fluid source component 520 in this example actually constitutes the above-mentioned combination. Figure 1A and Figure 1BThe entire fluid system 100 is described in two parts: pump 550 and fluid storage chamber 500. A sealed or welded line 520W defines one or more of the following: (a) a fluid source line 402A extending from fluid source port 554A to the area of ​​check valve 114; (b) the check valve 114 area; (c) pump 550 (e.g., formed as a foot-activated compressible ball type pump); (d) pump inlet 554; (e) pump outlet 552; (f) check valve 118 area; (g) fluid line 502; and / or (h) a storage chamber port (inlet) 510 leading to the fluid storage chamber 500 portion of the fluid source component 520. Figure 5C and Figure 5D As shown, fluid line 502 may be omitted or may be very short, for example, such that pump outlet 552 supplies fluid substantially directly to check valve 118 and / or check valve 118 may be directly connected to storage chamber port 510 and / or lead to internal chamber 500C of fluid storage chamber 500.

[0062] Figure 5C The sealing or welding line 520W at the upward-facing surface 500U shown is... Figure 3D Features at the ground-facing surface 300G of the first midsole component 300 shown match. More specifically: (a) at least a portion of the fluid source line 402A of the fluid source component 520 matches the position of the fluid line support area 314 of the first midsole component 300; (b) the check valve 114 area matches the position of the valve support area 316; (c) the pump 550 area matches the position of the pump support area 318; and (d) the check valve 118 area matches the position of the valve support area 320. The overall profile (e.g., outer periphery) of the fluid source component 520 may be shaped to fit into a recess 324 provided in the ground-facing surface 300G of the first midsole component 300.

[0063] Figure 5A , Figure 5C and Figure 5DThe example fluid source component 520 is also illustrated, including a reservoir port 512 that connects to a fluid line 504 that transfers fluid between the internal chamber 400C of the foot support bladder 400 and the internal chamber 500C of the fluid reservoir 500. Additionally, the example fluid source component 520 includes a fluid source port 554A that connects to a fluid line 402 to move fluid from the foot support bladder 400 to a pump 550 (via fluid source line 402A, check valve 114, and pump inlet 554). In this illustrated example, the reservoir port 512 and the fluid source port 554A are located on the side edges of the fluid source component 520 (e.g., adjacent to each other at the outer edge) and can be positioned within a receiving portion 310 of the first midsole component 300 in the final assembled sole structure 200. Fluid flow in the example fluid source component 520 is... Figure 5C Arrow 590 in the diagram shows the large fluid flow.

[0064] like Figure 5C and Figure 5D As shown, in this example, the storage chamber port 512 and the fluid source port 554A are located within a recess 508 formed on the outer side of the fluid source component 520 (e.g., at the inner wall 508W). The recess 508 may generally correspond in size, shape, and / or position to the receiving portion 310 in the first midsole component 300 and may be configured to accommodate the support component 600 as described in more detail below.

[0065] Figure 5C and Figure 5D Also shown are one or more recesses 522 formed in the fluid source component 520 (e.g., in the fluid reservoir 500 portion of the fluid source component 520). These recesses 522 may be formed as internal weld points, for example, where the inner surface of the upward-facing surface 500U is fixed (e.g., welded, bonded, etc.) to the inner surface of the ground-facing surface 500G. The recesses 522 in the fluid source component 520 may be positioned to correspond to the positions of corresponding protrusions 322 provided in the ground-facing surface 300G of the first midsole component 300. Although Figure 5C and Figure 5D An alternating pattern of recesses 522 in three rows oriented laterally in the middle and / or foreleg regions of the fluid source component 520 is shown; however, any desired number of recesses, number of rows, number of columns, size, shape, orientation, and / or arrangement of the recesses (or other engaging components) may be used in other specific embodiments of the art. Additionally or alternatively, if desired, Figure 5C and Figure 5DOne or more of the recesses 522 shown may be replaced by protrusions whose size, shape, and / or position are designed to engage with corresponding recesses provided on the ground-facing surface 300G of the first midsole component 300. Therefore, various surface engagements between the ground-facing surface 300G of the first midsole component 300 and the upward-facing surface 500U of the fluid source component 520 can be used without departing from the present technology.

[0066] Figures 6A to 6F Various views of support components 600 (e.g., fluid line support components and / or switch support components) that can be used in at least some instances of this technology are provided. Figure 6A A rear view of the support component 600 is provided; Figure 6B A front view is provided; Figure 6C An inward-facing side view is provided; Figure 6D It provides an externally facing side view; and Figure 6E and Figure 6F A perspective view is provided. The example support member 600 supports both: (i) a fluid line 402 connecting the foot support bladder 400 and the pump 550 portion of the fluid source component 520, and (ii) a fluid line 504 connecting the foot support bladder 400 and the fluid reservoir 500 portion of the fluid source component 520. Additionally, the example support member 600 supports [equipment / facilities] for [facilitating / enabling] the fluid system 100 in [the following contexts]. Figure 1A Lower pressure foot support configuration and Figure 1B The switching component 900 varies between higher pressure foot support configurations. Alternatively, different and / or separate components may be provided for supporting different fluid lines 402, 504, if desired. Still additionally or alternatively, different and / or separate components may be provided for supporting one or more fluid lines 402 and / or 504 and the switching component 900, if desired.

[0067] The support member 600 of this example includes: (a) a base region 602 that extends laterally into the entire sole structure 200 (and engages with) Figure 3D and Figure 10D(a) the base surface 312 of the first midsole component 300 shown; (b) the fluid line support surface 604; and (c) at least one switch support area. The bottom surface of the base region 602 in this example includes one or more recessed regions 602A configured to receive features of the upward-facing surface 500U of the fluid source component 520 (e.g., configured to receive the fluid source line 402A in the assembled sole structure 200 without clamping it closed, to receive the storage chamber port 512 and / or the fluid source port 554A in the assembled sole structure 200 without clamping it closed, etc.).

[0068] The support member 600 of this example includes a fluid line support surface 604, which includes two fluid line support regions 604A and 604B. While other arrangements are possible, in this illustrated example, the two fluid line support regions 604A and 604B are arranged adjacent to each other such that they will be spaced apart in the heel-to-toe direction in the ultimately assembled fluid system 100 and / or sole structure 200. In this example, the fluid line support region 604A is arranged to support a fluid line 402 extending between a foot support bladder 400 and a fluid source port 554A. The fluid line support region 604A includes a concave outer surface configured to lie beneath a portion of the tubular outer surface of the fluid line 402 and support a portion of the tubular outer surface of the fluid line 402 (e.g., as described below). Figure 9A and Figure 9B (Description in more detail). In this example, the concave outer surface of the fluid line support area 604A extends around an arc of approximately 180 degrees and forms part of the outer surface of the support member 600.

[0069] In this example, the fluid line support area 604B is arranged to support the fluid line 504 extending between the foot support bladder 400 and the storage chamber port 512. In this example, the fluid line support area 604B is located in front of the fluid line support area 604A (relative to the finally assembled fluid system 100, sole structure 200, and / or the entire footwear article 250). The fluid line support area 604B in this example also includes a concave outer surface configured to lie beneath a portion of the tubular outer surface of the fluid line 504 and support a portion of the tubular outer surface of the fluid line 504 (e.g., in conjunction with the following). Figure 9A and Figure 9B(Described in more detail). In this example, the concave outer surface of the fluid line support region 604B extends around an arc of approximately 180 degrees and forms part of the outer surface of the support member 600. In the illustrated example, the fluid line support regions 604A and 604B are positioned adjacent to each other and / or extend substantially parallel to each other, but other sizes, shapes, and / or relative arrangements and orientations are possible in other specific examples.

[0070] like Figures 6C to 6F As shown, the fluid line support surface 604 includes front, rear, and central raised ridges 604R, which define receiving portions of fluid line support regions 604A and 604B and separate fluid line support regions 604A and 604B from each other and from side support members 610F and 610R. The raised ridges 604R also provide a surface for receiving adhesive for securing the fluid line connector component 800 (which includes fluid lines 402 and 504) to the support member 600.

[0071] The fluid line support region 604B of this example also includes a recess or receiving portion 606 defined in its exposed surface. In this example structure, the receiving portion 606 is sized and shaped to accommodate a tube closure member 700, which, in the illustrated example, includes a cylindrical component (e.g., formed of a rigid plastic material (e.g., thermoplastic polyurethane, other thermoplastic elastomers, polyether block amides, etc.), formed of a metal or metal alloy, etc.). See Figure 7 and Figure 8 When placed in the receiving unit 606, as Figure 8 As shown, the outer surface 700A of the pipe closure component 700 protrudes outward into the fluid line support region 604B and abuts against the outer surface of the fluid line 504 when the fluid line 504 is installed in the fluid line support region 604B. The pipe closure component 700 provides a solid support surface for use when the switching component 900 is in a position such as... Figure 1A The closed configuration shown (and as will be explained in more detail below) helps to clamp and close the fluid line 504.

[0072] Figures 6A to 6FThe illustrated example also shows a support member 600 comprising switch support members, namely: a rear switch support member 610R and a front switch support member 610F. In this illustrated example, the rear switch support member 610R and the front switch support member 610F are spaced apart (e.g., connected via a base region 602), and fluid line support surfaces 604 (in this example, including fluid line support regions 604A and 604B) are provided between the rear switch support member 610R and the front switch support member 610F. In this example, each switch support member 610F, 610R includes one or more support elements for supporting the switch member 900. In this illustrated example, the front switch support member 610F includes a front support bore 612F, and the rear switch support member 610R includes a rear support bore 612R. The support bores 612F, 612R are arranged to receive axial elements 902F, 902R of the switch member 900 (see [reference needed]). Figure 11A and Figure 11B This allows the switch component 900 to be rotatably mounted on the support component 600. Rotation of the switch component 900 on an axis extending through the support holes 612F, 612R causes the fluid system 100 to engage as described above. Figure 1A and Figure 1B The description refers to the change between closed and open configurations.

[0073] According to this technology, the support member 600 can have any desired construction, be formed from any number of parts, and / or be formed from any desired material. In the example illustrated, the support member 600 can be formed as a single component from a rigid material, such as plastics (e.g., thermoplastic polyurethane, other thermoplastic elastomers, polyether block amides, metals, metal alloys, etc.). As some more specific examples, the support member 600 can be manufactured by injection molding, by another molding process, by 3D printing, etc.

[0074] In some embodiments of this technology, fluid lines 402 and 504 (e.g., plastic tubes) can be formed as separate components, such as as individual flexible polymer tubes. In such a configuration, one end of fluid line 402 can engage with foot support bladder 400 (e.g., at bladder port 410), and the other end of fluid line 402 can engage with fluid source component 520 (e.g., at fluid source port 554A). One side or surface of fluid line 402 can extend along and be supported by fluid line support region 604A of support component 600. Similarly, in such a configuration, one end of fluid line 504 can engage with foot support bladder 400 (e.g., at bladder port 412), and the other end of fluid line 504 can engage with fluid source component 520 (e.g., at storage chamber port 512). One side or surface of fluid line 504 can extend along and be supported by fluid line support region 604B of support component 600.

[0075] Alternatively, such as Figure 9A and Figure 9B As shown, fluid lines 402 and 504 may comprise multiple portions of a single fluid line connector component 800. The fluid line connector component 800 having fluid lines 402 and 504 can be formed in a manner similar to forming a fluid-filled bladder (e.g., when formed as a bladder, such as a foot support bladder 400 and / or a fluid source component 520). As a more specific example, two sheets 800A and 800B (or a folded sheet) of thermoplastic elastomer material can be joined together via a seam 800S using heat sealing, welding, or other techniques. The size and shape of the support surface 402S of the fluid line 402 portion can be designed to correspond to the size and shape of the fluid line support region 604A of the support component 600. Similarly, the size and shape of the support surface 504S of the fluid line 504 portion can be designed to correspond to the size and shape of the fluid line support region 604B of the support component 600. The size, shape, and relative position of the seam 800S can be designed to correspond to the position of the ridge 604R of the support member 600.

[0076] Figures 10A to 10C Various views of the fluid system 100 (with support member 600) without other footwear and / or sole structural parts are provided to illustrate how the various fluid system 100 components fit together. Figure 10A This is a top-view, outer perspective view of the fluid system 100. Figure 10B It is a bottom view, and Figure 10C It is an outside view. Figure 10D It is roughly along Figure 10B The perspective cross-section view taken from line 10D-10D in the image, but... Figure 10D This includes some additional 200 parts of the sole structure, for example, for a more complete context. See these figures along with... Figure 9A and Figure 9B As shown, the fluid tube connector component 800 has a generally C-shape, including, for example, a first end, a second end, and a connecting portion extending between the first and second ends (forming a tube for fluid lines 402 and 504). This connecting portion defines a concave chamber. The C-shape also accommodates the placement of the foot support bladder 400 and the fluid source component 520 in a vertically stacked relationship, and allows the fluid lines 402 and 504 to extend between the foot support bladder 400 and the fluid source component 520 without undesirably kinking or clamping shut. A first midsole component 300 extends into and fits within the space 100S defined between the ground-facing surface 400G of the foot support bladder 400 and the upward-facing surface 500U of the fluid source component 520.

[0077] The fluid system 100 may be formed from multiple parts, such as separate parts for the foot support bladder 400, the fluid source component 520 (and optionally for each of the pump 550 and the fluid reservoir 500), and the fluid conduit connector component 800. When formed as two or more separate parts, these parts may be fluidly connected to each other in any desired manner, such as by one or more of heat-sealed or welded joints, adhesives, mechanical connectors, etc. Alternatively, if desired, the fluid conduit connector component 800 or other fluid conduits (e.g., for fluid lines 402 and / or 504) may be integrally formed with one or more of: (a) the foot support bladder 400, (b) the fluid source component 520 (e.g., if the fluid source component 520 constitutes a bladder component), (c) the pump 550, and / or (d) the fluid reservoir 500 (e.g., if the fluid reservoir 500 is formed as a bladder component). In such structures, fluid lines 402 and / or 504 may be integrally formed as a single-piece construction with one or more of the following: (a) foot support bladder 400, (b) fluid source component 520, (c) pump 550, and / or (d) fluid storage chamber 500.

[0078] In addition, Figures 10A to 10D In the specific example illustrated (and other figures), the first fluid line 402 and the second fluid line 504 engage with or extend from the foot support bladder 400 at adjacent locations on a first side (e.g., lateral, optionally in the midfoot region) of the foot support bladder 400. The foot support bladder 400 may include physical ports (e.g., bladder ports 410, 412) respectively connected to the fluid lines 402 and 504, or one or more of the fluid lines 402 and / or 504 may be integrally formed with the foot support bladder 400. Additionally or alternatively, in Figures 10A to 10DIn the specific examples illustrated in (and other figures), the first fluid line 402 and the second fluid line 504 engage with or extend from the fluid source component 520 at adjacent locations on a first side (e.g., the outer side, optionally in the midfoot region) of the fluid source component 520. The fluid source component 520 may include physical ports (e.g., reservoir ports 554A, 512) respectively connected to the fluid lines 402 and 504, or one or more of the fluid lines 402 and / or 504 may be integrally formed with the fluid source component 520. The fluid source component 520 may constitute only a fluid pump (e.g., like a foot-activated pump 550, other manually activated pumps, battery-operated pumps, or compressors, etc.), only a fluid reservoir 500, or a combination of pump 550 / fluid reservoir 500 components as illustrated in these figures.

[0079] Figure 11A and Figure 11B A perspective view of a switch component 900 according to some aspects of the present technology is provided. The switch component 900 includes a front wall 900F, a rear wall 900R opposite to the front wall 900F, an outer surface 900X, and an inner surface 900I opposite to the outer surface 900X. The front wall 900F includes a front axial element 902F, and the rear wall 900R includes a rear axial element 902R. The front axial element 902F engages a corresponding front support hole 612F on a front switch support component 610F of a support component 600. See [link to relevant documentation]. Figures 6A to 6F Similarly, the rear axial element 902R engages with the corresponding rear support hole 612R on the rear switch support member 610R of the support member 600. When engaged in this manner, the switch member 900 is able to rotate relative to the support member 600 about the axes of the axial elements 902F and 902R.

[0080] Figure 11A and Figure 11B A front wall 900F including a front protrusion element 904F and a rear wall 900R including a rear protrusion element 904R are also shown. Depending on the rotational position of the switch member 900, the front protrusion element 904F can selectively engage the support member 600 (see...). Figures 6A to 6F and Figure 8 The front support recess 614F1 or 614F2 is movable between the front support recesses 614F1 and 614F2. Similarly, depending on the rotational position of the switch member 900, the rear protrusion element 904R can selectively engage the support member 600 (see [link to switch member 900]). Figures 6A to 6F and Figure 8The protruding elements 904F, 904R and the support recesses 614F1, 614F2, 614R1, 614R2 can be used as a stop mechanism to help hold the switch part 900 in the desired rotational position.

[0081] Rotation of the switching component 900 about axial elements 902F and 902R allows the switching component 900 to switch between two settings. One setting allows the top of the switching component 900 (above the axial elements 902F and 902R) to rotate inward and the bottom of the switching component 900 (below the axial elements 902F and 902R) to rotate outward. In this first setting (or configuration), the front protrusion element 904F engages with the front support recess 614F1, and the rear protrusion element 904R engages with the rear support recess 614R1. The engagement of the front protrusion element 904F with the front support recess 614F1, and the engagement of the rear protrusion element 904R with the rear support recess 614R1, helps to hold the switching component 900 in this setting position. In this setting, fluid lines 402 and 504 remain open, and the fluid system 100 is in... Figure 1B The higher pressure configuration shown.

[0082] The second configuration causes the top of the switching component 900 (above the axial elements 902F and 902R) to rotate outward, and the bottom of the switching component 900 (below the axial elements 902F and 902R) to rotate inward about the axial elements 902F and 902R. In this second configuration, the front protrusion 904F engages with the front support recess 614F2, and the rear protrusion 904R engages with the rear support recess 614R2. The engagement of the front protrusion 904F with the front support recess 614F2, and the engagement of the rear protrusion 904R with the rear support recess 614R2, helps to hold the switching component 900 in this configured position.

[0083] like Figure 11A and Figure 11B As shown, in this example structure, the inner surface 900I of the switching component 900 includes a switch support surface 906. In this illustrated example, the switch support surface 906 is located only adjacent to the pipe support surface 908B that houses the fluid line 504. Therefore, the switch support surface 906 is capable of interacting with the fluid line 504. The switch support surface 906 does not extend to the pipe support surface 908A that houses the fluid line 402. Therefore, the switch support surface 906 does not interact with the fluid line 402.

[0084] In the second setting, the top of the switch component 900 rotates outward, and the bottom of the switch component 900 rotates inward about the axial elements 902F and 902R, while the switch support surface 906 also rotates inward toward the fluid line 504. This action clamps and closes the fluid line 504 between the switch support surface 906 and the pipe closure component 700. Figure 10D Element 906X shows the position where the switch support surface 906 will contact the fluid line 504 (opposite to the position of the pipe closure member 700) to close the fluid line 504. In this way, the switch member 900 closes the fluid line 504 (e.g., clamps it closed between the switch support surface 906 and the pipe closure member 700) and places the fluid system 100 in place. Figure 1A The lower pressure configuration shown.

[0085] According to this technology, the switch component 900 can have any desired construction, be formed from any number of parts, and / or be formed from any desired material. In the example illustrated, the switch component 900 can be formed as a single component from a rigid material, such as plastics (e.g., thermoplastic polyurethane, other thermoplastic elastomers, polyether block amides, metals, metal alloys, etc.). As some more specific examples, the switch component 900 can be manufactured by injection molding, by another molding process, by 3D printing, etc.

[0086] While a specific combination of switch component 900 and switch support component 600 has been described above, many other specific types of switches and switching devices can be used in some embodiments of the art. For example, one or more of the recesses 614F1, 614F2, 614R1 and / or 614R2 on the support component 600 can be replaced by protrusions, and one or more of the corresponding protrusions 904F and / or 904R on the switch component 900 can be replaced by recesses. Different types of switches, such as "push-button" toggle switches (instead of this type of rotary switch component 900), can also be used, which move the switch support surface 906 to contact or de-contact with the fluid line 504. Additionally or alternatively, the switch component 900 can have a substantially different appearance from the specific example shown, such as different sizes, different shapes, different textures on its outer surface 900X, etc.

[0087] Figures 12A to 12DOuter, inner, top, and bottom views of a second midsole component 1000 that may be provided in a sole structure 200 according to at least some examples of the present technology are provided. In the examples illustrated, the second midsole component 1000 includes a single polymer foam component (e.g., composed of ethylene-vinyl acetate (EVA) foam, polyurethane foam, etc.), but other materials (e.g., rubber, other elastomers, thermoplastic polyurethane, etc.) may also be used. Alternatively, if desired, the second midsole component 1000 may be made of two or more components, including: one or more polymer foam midsole components, one or more mechanical shock-absorbing components, one or more fluid-filled bladders, one or more heel components, one or more forefoot components, one or more arch support components, etc.

[0088] The second midsole component 1000 includes an upward-facing surface 1000U and a ground-facing surface 1000G. An outer surface 1000L and an inner surface 1000M extend along both sides of the second midsole component 1000 between the upward-facing surface 1000U and the ground-facing surface 1000G. These side surfaces 1000L and / or 1000M can have any desired size, shape, thickness, texture (e.g., including smooth walls, textured walls, combinations, etc.), decorative features, etc. Figures 10A to 10D The features shown in (and other figures) represent an example of a decorative design for a wall surface. The second midsole component 1000 also includes a forefoot tip 1000T and a heel end 1000H. Thus, the second midsole component 1000 of this illustration spans across and lies beneath and / or supports all or substantially all (e.g., at least 90% or even at least 95% of the surface area) of the wearer's foot's sole surface. The second midsole component 1000 of this example also includes a protruding surface 1010 that adapts to the space defined by the midfoot connection portion 400M of the foot support sac 400.

[0089] In this example, the second midsole component 1000 is positioned such that its ground-facing surface 1000G covers the upward-facing surface 400U of the foot support pouch 400 (and optionally covers at least some of the upward-facing surfaces 300U of the first midsole component 300 - see Figure 10D ).like Figure 12D As shown, the ground-facing surface 1000G of the second midsole component 1000 may include structures (e.g., one or more recesses 1000R and / or protrusions 1000P) that match and / or accommodate corresponding structures provided on the foot support bladder 400 (e.g., midsole protrusions 1000P extending into the seam or weld 404 of the foot support bladder 400). Figure 12DAs can be clearly seen in the recess 1000R shown, in this example, the front edge 1000FE of the recess 1000R (and the front edge 400FE of the foot support bladder 400 in this example) will be located not far from the foremost toe area of ​​the sole structure 200. In some examples, the front edges 1000FE and 400FE will be located between parallel planes at 0.55L and 0.85L (relative to the longitudinal length L of the second midsole component 1000, the entire sole structure 200, and / or the entire footwear article 250).

[0090] Figures 13A to 14B The illustrations depict example heel support components 1100L and 1100M that may be included in a sole structure 200 and / or footwear article 250 according to at least some embodiments of the present technology. In the illustrated examples, two separate heel support components are shown: a lateral heel support component 1100L (…). Figure 13A and Figure 13B ) and medial heel support component 1100M ( Figure 14A and Figure 14B Heel support components 1100L, 1100M may extend upward along both sides of the upper 202 at the heel area to support the sides of the wearer's heel. Alternatively, if desired, a single heel support component may be provided, for example, a rear heel element connecting the lateral heel support component 1100L and the medial heel support component 1100M as a single component. Such a single heel support component may have the structure of conventional heel stabilizers known and used in the footwear industry. One or more heel support components 1100L, 1100M of this type may be joined in the sole structure 200 and / or footwear article 250 structure in any desired manner, including by using adhesives, sewn seams, mechanical fasteners, etc.

[0091] Although Figures 13A to 14B The specific component structure is shown, but the outer heel support component 1100L and / or the inner heel support component 1100M can have many desired sizes, shapes, textures (e.g., including smooth walls, textured walls, combinations, etc.), decorative features, etc. Figures 13A to 14B The lines and grooves shown in (and other figures) represent some examples of decorative designs used for the heel support components 1100L and 1100M.

[0092] Figures 15A to 15CTop, top, and bottom views of an outsole component 1200 according to some embodiments of the present technology are shown respectively. The outsole component 1200 may be made of one or more components, and these components may be made of any desired material, including conventionally known materials used for footwear outsoles (e.g., rubber materials, thermoplastic polyurethane materials, foam materials, etc.). Furthermore, without departing from the present technology, the outsole component 1200 may have any desired tread pattern, any desired type of adhesive friction element, and / or adhesive friction element patterns (e.g., including anti-slip studs or cleats, raised protrusions, recessed grooves, etc.).

[0093] like Figure 15A and Figure 15B As shown, the upward-facing surface 1200G of the example outsole component 1200 includes one or more of the following: (a) a base surface 1212 (e.g., for engaging the base region 602 of the support component 600), (b) a fluid line support region 1214 (e.g., for engaging and / or accommodating at least a portion of the fluid source line 402A of the fluid source component 520), (c) a valve support region 1216 (e.g., for engaging and / or accommodating at least a portion of the check valve 114), and (d) a pump support region 1218 (e.g., for engaging and / or accommodating the pump 550). (e) at least a portion of a recessed area (e.g., a circular recess), (f) a valve support area 1220 (e.g., for engaging and / or accommodating at least a portion of a check valve 118), (g) one or more protrusions 1222 (e.g., in the midfoot and / or forefoot areas, configured to engage corresponding recesses 522 on the fluid reservoir 500 (or other portions of the fluid source component 520), and / or (g) a receiving portion 1224 for accommodating at least a portion of the ground-facing surface 500G of the fluid source component 520 (e.g., at least a portion of the fluid reservoir 500). In this way, one or more of the following: (a) the base region 602 of the support member 600, (b) the fluid source line 402A, (c) the check valve 114, (d) the pump 550, (e) the check valve 118, and / or (f) the recess 522 will be located between (e.g., sandwiched between) the corresponding support structures provided on (i) the upward-facing surface 1200U of the outsole member 1200 and (ii) the ground-facing surface 300G of the first midsole member 300 (see Figure 3D ).

[0094] Base surfaces 312 and 1212 can support and retain the base region 602 of the support member 600, and the base region 602 can be fixed to the base surfaces 312 and / or 1212 by one or more of adhesives, mechanical fasteners, fusion techniques (e.g., welding, fusion bonding, hot melt techniques, etc.). Fluid line support regions 314 and 1214 can support and retain the fluid source line 402A, and the fluid source line 402A can be fixed to the fluid line support regions 314 and / or 1214 by one or more of adhesives, mechanical fasteners, fusion techniques, etc. Valve support regions 316 and 1216 can support and retain check valve 114 (or check valve 114 region of fluid source component 520), and check valve 114 (or check valve 114 region of fluid source component 520) can be secured to valve support regions 316 and / or 1216 by one or more of adhesives, mechanical fasteners, fusion techniques, etc. Pump support regions 318 and 1218 can support and retain pump 550, and pump 550 can be secured to pump support regions 318 and / or 1218 by one or more of adhesives, mechanical fasteners, fusion techniques, etc. Valve support regions 320 and 1220 can support and retain check valve 118 (or check valve 118 region of fluid source component 520), and check valve 118 (or check valve 118 region of fluid source component 520) can be secured to valve support regions 320 and / or 1220 by one or more of adhesives, mechanical fasteners, fusion techniques, etc. Protrusions 322 and 1222 can be received in corresponding recesses 522, and protrusions 322 and / or 1222 can be secured in recesses 522 by one or more of adhesives, mechanical fasteners, fusion techniques, etc. The upward-facing surface 500U of fluid source component 520 can be adapted to and / or secured in the recess 324 of the ground-facing surface 300G of the first midsole component 300 (e.g., by one or more of adhesives, mechanical fasteners, fusion techniques, etc.). Similarly, the ground-facing surface 500G of the fluid source component 520 can be adapted to the receiving portion 1224 of the upward-facing surface 1200U of the outsole component 1200 and / or can be fixed in the receiving portion 1224 of the upward-facing surface 1200U of the outsole component 1200 (e.g., by one or more of adhesives, mechanical fasteners, fusion techniques, etc.).

[0095] Figure 15A and Figure 15BThe diagram also shows the front edge 1224F of the receiving portion 1224 positioned slightly rearward from the foremost toe region of the outsole component 1200. As some more specific examples, based on the longitudinal length L of the sole structure 200 and / or the entire footwear article 250, the foremost extent of the front edge 1224F of the receiving portion 1224, the foremost extent of the fluid source component 520, and / or the foremost extent of the fluid storage chamber 500 can be positioned as follows: (a) in front of a parallel plane at P=0.55L (and in some instances, in front of a parallel plane at P=0.6L or in front of a parallel plane at P=0.65L), and (b) behind a parallel plane at P=0.85L (and in some instances, behind a parallel plane at P=0.8L or behind a parallel plane at P=0.75L). In at least some portions of the forefoot area of ​​the example sole structure 200, the upward-facing surface 1200U will contact and be secured to the ground-facing surface 300G of the first midsole component 300 (e.g., by one or more of adhesives, mechanical fasteners, fusion techniques, stitching seams, etc.).

[0096] Figures 15A to 15C Other features of the pump activator region of the outsole component 1200 are also shown. In addition to the pump support region 1218, which has a bulbous inner surface and generally corresponds to the lower portion of the outer surface shape of the pump 550, the interior of the pump support region 1218 includes a raised activator structure 1218A that pushes inwardly against the outer surface of the pump 550. This raised activator structure 1218A: (i) helps ensure direct contact between the outer surface of the pump 550 and the outsole component 1200, and (ii) facilitates direct compression of the pump 550 when a contact force is applied at the pump activator component 1300 to the ground-facing surface 1200G of the outsole component 1200. Thus, the pump 550 will immediately move fluid when the spherical shape of the pump 550 is subjected to any compression, and a relatively large amount of fluid will be moved with each pump cycle.

[0097] Figure 15C (together) Figure 2A , Figure 2B , Figure 2D and Figure 2E The image shows that the ground-facing surface 1200G of the outsole component 1200 includes an outwardly extending surface 1218G at the pump support area 1218. This outwardly extending surface 1218G is located directly below the pump 550 throughout the sole structure 200 and may have a generally circular shape. In at least some embodiments of this technology, the pump activator component 1300 may engage with this outwardly extending surface 1218G (e.g., by one or more of adhesives, mechanical fasteners, fusion techniques, etc.). Figures 16A to 16CBottom, top, and perspective views of an example pump activator component 1300 that can be secured to the outwardly extending surface 1218G of the pump support region 1218 are provided. The upward-facing surface 1300U of the pump activator component 1300 may have a shape that matches at least a portion of the external shape of the outwardly extending surface 1218G (e.g., a generally circular shape). The ground-facing surface 1300G of the pump activator component 1300 may have any desired shape. In some instances, the ground-facing surface 1300G may include one or more attached friction elements 1300T (with any desired size, shape, number, and / or configuration). The pump activator component 1300 may be made of any desired material, including abrasion-resistant materials, wear-resistant materials, etc., including materials known and used in footwear outsole constructions. The pump activator component 1300 may provide additional protection to help prevent undesirable punctures to the fluid system 100 (e.g., by debris extending through the outsole component 1200 at the pump support region 1218).

[0098] In some embodiments of this technology, the pump activator component 1300 may be located on the outsole component 1200, the sole structure 200, and / or the footwear article 250: (a) behind a parallel plane at 0.4L, and in some embodiments, behind a parallel plane at 0.35L or 0.3L, and / or (b) in front of a parallel plane at 0.1L, and in some embodiments, in front of a parallel plane at 0.12L or 0.15L. See also Figure 2A Therefore, in some instances, the pump activator component 1300 will be located in the heel area of ​​the sole structure 200 and / or footwear article 250. Additionally or alternatively, if desired, a pump (e.g., similar to pump 550) and a pump activator component (e.g., the type described with respect to pump activator component 1300) may be provided in the forefoot area (and / or midfoot area) of the sole structure 200 and / or footwear article 250. Figure 15C The broken line 1310 is included to indicate possible locations of the pump and / or pump activator components based on the forefoot, for example as an alternative to a heel-based location or as a second pump (e.g., connected in series with pump component 550 (e.g., of the type described in U.S. Patent No. 11,510,458 B2, which is incorporated herein by reference in its entirety). When provided in the forefoot, pump activator component 1300 (and corresponding pump structure) may be located on outsole component 1200, sole structure 200, and / or footwear article 250: (a) behind a parallel plane at 0.95L, and in some instances behind a parallel plane at 0.92L or 0.9L, and / or (b) in front of a parallel plane at 0.55L, and in some instances in front of a parallel plane at 0.58L or 0.6L.

[0099] Figures 17A to 20B The illustration shows features of another example fluid system 1700, foot support system, sole structure, and / or footwear article according to some aspects of the present technology. In the above... Figures 1A to 16C In one example, pump 550 is arranged to draw fluid from foot support bladder 400 and pump the fluid to fluid storage chamber 500. In this manner: (a) when fluid system 100 (e.g., fluid line 504) is in a closed configuration, the fluid pressure in foot support bladder 400 decreases as the wearer steps down, thereby activating pump 550 and transferring fluid to fluid storage chamber 500; and (b) when fluid system 100 (e.g., fluid line 504) is in an open configuration, the fluid pressure in foot support bladder 400 and fluid storage chamber 500 are equal, and fluid flows freely around fluid system 100. However, in Figures 17A to 20B In the fluid system 1700, as will be described in more detail below: (a) when the fluid system 1700 (e.g., fluid line 1766) is in a closed configuration, the fluid pressure in the fluid reservoir 1720 decreases as the wearer steps down, thereby activating the pump 1730 and transferring fluid to the foot support bladder 1710, and (b) when the fluid system 1700 (e.g., fluid line 1766) is in an open configuration, the fluid pressures in the foot support bladder 1710 and the fluid reservoir 1720 are equal, and fluid flows freely around the fluid system 100. Therefore, Figure 17A and Figure 17B The fluid system 1700 in the schematic diagram can be considered to be essentially similar to Figure 1A and Figure 1B The fluid system 100 in the schematic diagram has its positions interchanged, except that the foot support bladders 400 / 1710 and the fluid storage chambers 500 / 1720. Additionally or alternatively, Figure 19 The combined fluid source component 520 (e.g., including pump 1730 and fluid storage chamber 1720) is substantially similar to the one described above. Figures 5A to 5D The fluid source components 520 of the fluid system 100 described herein, except that the pump 1730 and check valves 1750 and 1752 (e.g., one-way valves) are oriented in opposite directions (e.g., from the fluid storage chamber 1720 to the foot support bladder 1710) to pump fluid.

[0100] Figures 17A to 20BA fluid system 1700 (including a fluid storage chamber 1720, a pump 1730, a combined fluid source component 520, and / or a foot support bladder 1710) may be included in a sole structure 200 and / or footwear article 250, the sole structure 200 and / or footwear article 250 having an upper 202, a first midsole component 300, a support component 600, a tube closure component 700, a fluid tube connector component 800, a switch component 900, a second midsole component 1000, one or more heel support components 1100L and / or 1100M, an outsole component 1200, and / or having the above-mentioned... Figures 1A to 16C The pump activator component 1300 is described as having any of the various features, options and / or alternatives of the components shown.

[0101] Now we will combine Figure 17A and Figure 17B The schematic diagram illustrates this example fluid system 1700 in more detail. The fluid system 1700 can be incorporated into foot support systems (e.g., sole structures) and / or footwear articles in various ways, for example, in any manner and / or using any structure and / or portion described in more detail above. This example fluid system 1700 is a “closed system,” meaning that the fluid system 1700 has a fixed amount (e.g., mass) of fluid (e.g., gas, such as air or other gases, including gases commonly known and used in foot support bladder systems) sealed within it, and the fluid system 1700 does not introduce new fluid from the external environment and does not discharge fluid to the external environment. However, alternatively, at least some aspects of this technology can be used for “open” fluid systems, such as fluid systems that introduce air (or other gases) from the external environment and / or discharge air (or other gases) to the external environment to change the foot support pressure in the foot support bladder.

[0102] Figure 17A A fluid system 1700 in a "high-pressure" foot support configuration is shown, and Figure 17B A fluid system 1700 in a "low-pressure" foot support configuration is shown. As illustrated in these figures, the fluid system 1700 includes a foot support bladder 1710 (which may have any of the various features, structures, and / or options described above for foot support bladder 400). Additionally, the fluid system 1700 includes a fluid reservoir 1720 (which may include a fluid-filled bladder or other fluid container, for example, having any of the various features, structures, and / or options described above for fluid reservoir 500). A pump 1730 (e.g., a foot-activated pump, such as a ball-type pump) moves fluid from the fluid reservoir 1720 to the foot support bladder 1710. When the switching component 1740 is closed, as... Figure 17AAs shown, pump 1730 removes fluid from fluid reservoir 1720 and moves fluid into foot support bladder 1710 to place foot support bladder 1710 in a higher-pressure foot support configuration. Specifically, compression of the internal chamber 1730C of pump 1730 (e.g., in response to a user's footstep) forces fluid toward pump outlet 1732, while check valve 1750 prevents fluid from flowing back from pump 1730 to fluid reservoir 1720 via fluid line 1760. As long as the pressure generated by the compression of pump 1730 is greater than the pressure in foot support bladder 1710, fluid will move through fluid line 1762, through check valve 1752, through fluid line 1764, and into the internal chamber 1710C of foot support bladder 1710 (e.g., through foot support bladder inlet port 1712). Alternatively, fluid line 1762 may be omitted or may be very short, such that pump outlet 1732 supplies fluid substantially directly to check valve 1752, and / or check valve 1752 may be directly connected to fluid source component outlet port 520O (e.g., the outlet port of fluid source component 520). When the internal chamber 1730C of pump 1730 expands again (e.g., when the user lifts his / her foot off the contact surface), fluid is drawn out of the internal chamber 1720C of fluid reservoir 1720, enters fluid line 1760 through reservoir outlet port 1722, and enters the internal chamber 1730C of pump 1730 (via check valve 1750 and pump inlet 1734). Figure 17A and Figure 17B The dotted line marked 520 outlines what can be contained below. Figure 19 The components within the fluid source component 520 are discussed in more detail. This fluid source component 520 may have components that are combined with those described above. Figures 5A to 5D The fluid source component 520 described has the same general structure, features, options, and alternatives (except, as mentioned above, the pump 1730 and check valves 1750, 1752 are oriented in conjunction with the fluid source component 520). Figures 5A to 5D The fluid is transported in the opposite direction described.

[0103] exist Figure 17A In the configuration shown: (i) a closed switch component 1740 (which may have the above-mentioned combination) Figures 6A to 11B(ii) The described switching components and structure prevent fluid from moving from the foot support bladder 1710 to the fluid reservoir 1720 via the fluid line 1766, and (ii) the check valve 1752 prevents fluid from flowing from the foot support bladder 1710 to the pump 1730 via the fluid line 1762. Therefore, in this configuration, over time (e.g., after one or more foot cycles), by activating the pump 1730, fluid moves from the fluid reservoir 1720 to the foot support bladder 1710, thereby placing the foot support bladder 1710 at a higher pressure than the fluid reservoir 1720. This action and configuration place the example foot support bladder 1710 at a higher pressure in this foot support configuration.

[0104] When the switch component 1740 is opened, such as Figure 17B As shown, this opens the fluid line 1766 and allows fluid to flow from the foot support bladder 1710 via the fluid line 1766 to the fluid storage chamber 1720 (e.g., fluid flows between the foot support bladder outlet port 1714 and the fluid source component inlet port 520I (the inlet of the fluid source component 520, which can directly connect to the internal chamber 1720C of the fluid storage chamber)). This switching action equalizes the pressure in the internal chamber 1710C of the foot support bladder 1710 and the internal chamber 1720C of the fluid storage chamber 1720, for example, thereby decreasing the pressure in the internal chamber 1710C and increasing the pressure in the internal chamber 1720C. This action and configuration place this example foot support bladder 1710 in a lower pressure foot support configuration. In use, when the user... Figure 17B In the configuration shown, when the pump 1730 is stepped on, the fluid will flow freely around the circuit (from the pump 1730, through the fluid line 1764, into the foot support bladder 1710, through the fluid line 1766, into the fluid storage chamber 1720, through the fluid line 1760 and back into the pump 1730).

[0105] Figure 18 A top view is provided of a foot support bladder 1710 that can be used in at least some instances of a fluid system 1700. The foot support bladder 1710 may have features combined with the above. Figures 4A to 4D The foot support bladder 400 described has the same overall structure, features, options, and alternatives as any of the following, except: (i) Figures 4A to 4D The bladder port 410 is used as an outlet port, while the corresponding foot support bladder inlet port 1712 is used as a fluid inlet port, and (ii) Figures 4A to 4D The bladder port 412 serves as the inlet port, while the corresponding foot support bladder outlet port 1714 serves as the fluid outlet port. Figure 18 and Figures 4A to 4D When using the same reference numerals, refer to the same or similar parts and / or features, and many overlapping descriptions may be omitted.

[0106] The foot support bladder 1710 can be formed from a thermoplastic elastomer material (e.g., two sheets, a folded sheet, etc.) in a manner conventionally known and used in the footwear industry. The illustrated example foot support bladder 1710 includes an upward-facing surface 400U and a ground-facing surface 400G (e.g., see...). Figure 4C ) and sealed peripheral seams 400S, wherein sheets forming surfaces 400U, 400G are welded, heat-sealed and / or otherwise joined together. Internal chamber 1710C (attached above) Figure 17A and Figure 17B The described area is defined between the upward-facing surface 400U and the ground-facing surface 400G, and inside the sealed peripheral joint 400S. One or more internal joints or welds 404 may be provided. Figure 18 One example is shown, for instance, to control the shape of the foot support bladder 1710 when inflated.

[0107] According to the present technology, the foot support bladder 1710 can have various shapes and / or sizes. In the example illustrated, the foot support bladder 1710 includes: (i) a heel region 1710H (e.g., supporting at least 50% of the surface area of ​​the wearer's heel), (ii) a forefoot region 400F (e.g., supporting at least 50% of the surface area of ​​the wearer's forefoot), and (iii) a midfoot connection portion 400M, which is narrower than the heel region 400H and the forefoot region 400F and offset laterally towards the foot support bladder 400. The internal chamber 1710C of the example foot support bladder 1710 in this illustration extends continuously between the heel region 400H and the forefoot region 400F through the midfoot connection portion 400M. In fact, the internal chamber 1710C of the example foot support bladder 400 illustrated extends continuously throughout the entire foot support bladder 1710 (except at any internal weld 404 and / or recess), making the entire internal chamber 1710C fluidly connected.

[0108] Figure 18The example foot support bladder 1710 is also illustrated, including a foot support bladder inlet port 1712 that connects to a fluid line 1764 that supplies fluid from a pump 1730 to the internal chamber 1710C of the foot support bladder 1710. Additionally, the example foot support bladder 1710 includes a foot support bladder outlet port 1714 that connects to a fluid line 1766 that extends between the internal chamber 1720C of a fluid reservoir 1720 and the internal chamber 1710C of the foot support bladder 1710, connecting the internal chamber 1720C of the fluid reservoir 1720 to the internal chamber 1710C of the foot support bladder 1710. In the example illustrated, the foot support bladder inlet port 1712 and the foot support bladder outlet port 1714 are located on the side edge of the foot support bladder 1710 (e.g., adjacent to each other at the outer edge in the midfoot connection portion 400M), and they may be positioned at or within the receiving portion 310 of the first midsole component 300 in the finally assembled sole structure 200. Figure 18 The enlarged arrow 1780 shown illustrates the direction of fluid flow relative to the foot support bladder 1710 in this example fluid system 1700.

[0109] Figure 19 A top view is provided of a fluid source component 520 having a combined fluid storage chamber 1720 (e.g., a container) and a pump 1730 component, which can be used in at least some instances of a fluid system 1700. The fluid source component 520 may have the same combination as described above. Figures 5A to 5D The fluid source component 520 described has the same overall structure, features, options, and alternatives as any of: (i) pump 1730 and check valves 1750 and 1752, which operate in conjunction with Figures 5A to 5D The instance moves the fluid in the opposite direction, (ii) fluid source port 554A ( Figures 5A to 5D ) is used as the inlet port, while the corresponding fluid source component outlet port 520O is used as the fluid outlet port, and (iii) the storage chamber port 512 ( Figures 5A to 5D The outlet port is used as the fluid source component inlet port 520I, while the corresponding inlet port 520I is used as the fluid inlet port. Figure 19 and Figures 5A to 5D When using the same reference numerals, refer to the same or similar parts and / or features, and many overlapping descriptions may be omitted.

[0110] Figure 19A top view is provided of an example fluid source component 520 (e.g., including a combined pump 1730 and fluid reservoir 1720) that can be used according to some examples of the present technology. Any desired type of fluid source component 520 (e.g., a fluid container) can be used in examples of the present technology. However, in the example illustrated, the fluid source component 520 constitutes a fluid-filled bladder, for example, formed from a thermoplastic elastomer material (e.g., two sheets, a folded sheet, etc.) in a manner conventionally known and used in the footwear industry. The example fluid source component 520 illustrated includes an upward-facing surface 500U and a ground-facing surface 500G (see...). Figure 5D ) and sealed peripheral seams 500S, wherein sheets forming surfaces 500U and 500G are welded, heat-sealed, and / or otherwise joined together. Internal chamber 1720C (attached above) Figure 17A and Figure 17B The described portion is defined between the upward-facing surface 500U and the ground-facing surface 500G and inside the sealed peripheral joint 500S. One or more internal joints, welds, or recesses 522 may be provided, for example, to control the shape of the fluid source component 520 and / or to form additional components within the fluid source component 520, which will be described in more detail below.

[0111] According to the present technology, the fluid source component 520 can have various shapes and / or sizes. In the example illustrated, the fluid source component 520 includes: (i) a heel region 500H (e.g., which supports at least 50% (and in some embodiments, at least 75%) of the surface area of ​​the wearer's heel), (ii) a forefoot region 500F (e.g., which supports at least 15% (and in some embodiments, at least 20% or at least 25%) of the surface area of ​​the wearer's forefoot), and (iii) a midfoot portion 500M between the heel region 500H and the forefoot region 500F. The internal chamber 1720C of the example fluid source component 520 illustrated extends continuously through the midfoot portion 500M between the heel region 500H and the forefoot region 500F. In fact, the internal chamber 1720C of the example fluid source component 520 illustrated extends continuously throughout the fluid source component 520 (except at any internal welds 520W and / or recesses 522).

[0112] The entire structure of the fluid source component 520 in this example actually constitutes the above-mentioned combination. Figure 17A and Figure 17BThe entire fluid system 1700 is described in two parts: pump 1730 and fluid storage chamber 1720. A sealed or welded line 520W defines one or more of the following: (a) a fluid line 1760 extending from fluid storage chamber 1720 to the area of ​​check valve 1750, (b) the check valve 1750 area, (c) pump 1730 (e.g., formed as a foot-activated compressible ball-type pump), (d) pump inlet area 1734, (e) pump outlet area 1732, (f) check valve area 1752, (g) internal fluid line 1768, and / or (h) fluid source component outlet port 520O (which may be connected to fluid line 1764 supplying fluid to foot support bladder 1710).

[0113] Figure 19 The sealing or welded conduit 520W at the upward-facing surface 500U shown can be connected to a feature at the ground-facing surface 300G of the first midsole component 300 (e.g., Figure 3D The fluid source component 520 is matched to the type shown. More specifically: (a) at least a portion of the internal fluid line 1768 of the fluid source component 520 matches the position of the fluid line support area 314 of the first midsole component 300; (b) the check valve 1750 area matches the position of the valve support area 320; (c) the pump 1730 area matches the position of the pump support area 318; and (d) the check valve 1752 area matches the position of the valve support area 316. The overall profile (e.g., outer periphery) of the fluid source component 520 can be shaped to fit into the... Figure 3D The recess 324 is provided in the ground-facing surface 300G of the first midsole component 300 shown.

[0114] Figure 19 The example fluid source component 520 is also illustrated, including an inlet port 520I that connects to a fluid line 1766 that transfers fluid between an internal chamber 1710C of the foot support bladder 1710 and an internal chamber 1720C of the fluid storage chamber 1720. Additionally, the example fluid source component 520 includes an outlet port 520O that connects to a fluid line 1764 to move fluid from the fluid source component 520 (e.g., from the pump 1730) to the foot support bladder 1710. In this illustrated example, the fluid source component inlet port 520I and the fluid source component outlet port 520O are located on the side edges of the fluid source component 520 (e.g., adjacent to each other at the outer edge) and can be positioned within a receiving portion 310 of the first midsole component 300 in the ultimately assembled sole structure 200. Figure 19 The enlarged arrow 1780 shown illustrates the direction of fluid flow through the fluid source component 520 in this example fluid system 1700.

[0115] like Figure 19 As shown, in this example, the fluid source component inlet port 520I and the fluid source component outlet port 520O are located within a recess 508 formed on the outer side of the fluid source component 520 (e.g., at the inner wall 508W). The recess 508 may generally correspond in size, shape, and / or position to the receiving portion 310 in the first midsole component 300 and may be configured to accommodate the support component 600.

[0116] Figure 19 Also shown are one or more recesses 522 formed in the fluid source component 520 (e.g., in the fluid reservoir 1720 portion of the fluid source component 520). These recesses 522 may be formed as internal weld points, for example, where the inner surface of the upward-facing surface 500U is fixed (e.g., welded, bonded, etc.) to the inner surface of the ground-facing surface 500G. The recesses 522 in the fluid source component 520 may be positioned to correspond to the positions of corresponding protrusions 322 provided in the ground-facing surface 300G of the first midsole component 300. Although Figure 19 An alternating pattern of recesses 522 in three rows oriented laterally in the middle and / or foreleg regions of the fluid source component 520 is shown; however, any desired number of recesses, number of rows, number of columns, size, shape, orientation, and / or arrangement of the recesses (or other engaging components) may be used in other specific embodiments of the art. Additionally or alternatively, if desired, Figure 19 One or more of the recesses 522 shown may be replaced by protrusions whose size, shape, and / or position are designed to engage with corresponding recesses provided on the ground-facing surface 300G of the first midsole component 300. Therefore, various surface engagements between the ground-facing surface 300G of the first midsole component 300 and the upward-facing surface 500U of the fluid source component 520 can be used without departing from the present technology.

[0117] Figure 18 and Figure 19 The foot support bladder 1710 and fluid source component 520 shown can be combined with the above combination. Figures 1A to 16C In the described footwear article 250 and sole structure 200 (replacing the foot support bladder 400 and fluid storage chamber 500), in such footwear article 250 and sole structure 200, as well as... Figures 6A to 11B The same switching system components shown (e.g., 600, 700, 900). Additionally or alternatively, if desired, Figure 17A and Figure 17BFluid lines 1764 and 1766 may have any of the structures, features, options, and / or alternatives described above for fluid lines 402 and 504. As some more specific examples, fluid lines 1764 and 1766 may be coupled as described above, if desired. Figures 6A to 8 The described type of support component 600 can be combined with the above. Figure 11A and Figure 11B The same manner described interacts with the switching component 900. Still additionally or alternatively, if desired, fluid lines 1764 and 1766 can form the above combination. Figure 9A and Figure 9B Multiple parts of a single fluid pipe connector component 800 of the described type, for example, fluid pipe 402 is replaced by fluid pipe 1764 and fluid pipe 504 is replaced by fluid pipe 1766.

[0118] As described above, aspects of this technology include a switching system 1740 configured to change the fluid line 1766 between an open configuration and a closed configuration and / or to change the foot support system, sole structure 200, and / or footwear article 250 between a higher pressure foot support configuration (e.g., the fluid line 1766 is in a closed configuration) and a lower pressure foot support configuration (e.g., the fluid line 1766 is in an open configuration). In the closed configuration (or the higher pressure foot support configuration), the switching system 1740 may include a switching member 900 having a support surface 906 (e.g., a protrusion) movable to clamp and close the fluid line 1766 against a tube closure member 700, for example, as described above. Figures 6A to 11B The closure of fluid line 504 is described.

[0119] Figure 20A and Figure 20B A cross-sectional view of a footwear article 250 according to some aspects of the present technology is provided, the footwear article 250 having the above-mentioned bonding Figures 17A to 19 The fluid system described is of type 1700. Figure 20A Fluid line 1766 is shown in an open configuration (lower pressure foot support configuration), and Figure 20B Fluid line 1766 is shown in a closed configuration (higher pressure foot-supported configuration). Figure 20A and Figure 20B When the same reference numerals are used in other figures, the same or similar parts (including the various structural features, options and / or alternatives discussed above) are referenced, and many overlapping descriptions may be omitted.

[0120] As described above, when fluid line 1766 is in a closed configuration, pump 1730 moves fluid from fluid reservoir 1720 to foot support bladder 1710 via fluid line 1764. Because the return fluid line 1766 is closed, this pumping action increases the fluid pressure in foot support bladder 1710 (because check valve 1752 prevents fluid from returning to pump 1730) and decreases the fluid pressure in fluid reservoir 1720. Therefore, walking in footwear may result in an increase in pressure in foot support bladder 1710. In some instances of this technology, after sufficient pump 1730 cycles have been completed (e.g., after sufficient steps have been taken to activate the foot activation pump 1730), this pumping action, and the movement of fluid when the fluid line 1766 is in a closed configuration, will result in: (i) a reduction in the height dimension of the fluid reservoir 1720 and / or the collapse of the fluid reservoir 1720 (when fluid is pumped out of it) and / or (ii) a reduction in the height dimension of the entire sole structure 200 and / or footwear 250. (H1 and H3) Figure 20A ) respectively with H2 and H4 ( Figure 20B Therefore, in comparison with the lower pressure foot support configuration ( Figure 20A The low-pressure foot support configuration transitions to a higher-pressure foot support configuration. Figure 20B When P (high) is reached, the fluid system 1700, the sole structure 200, and the footwear 250 will be... Figure 20A The configuration shown transitions to Figure 20B The configuration is shown in the diagram. Because fluid movement occurs incrementally with each step, the reduction in height dimension and / or change in foot support pressure can be relatively gradual. In some cases, the wearer of footwear 250 and / or others may not easily perceive this reduction in height dimension gradually, although the overall height dimension reduction may become visually perceptible over time (e.g., after a series of steps).

[0121] On the other hand, when the switching component 1740 changes to open the fluid line 1766 (e.g., through interaction between the user and the switching component 1740), the fluid system 1700, sole structure 200, and footwear 250 of this example will equalize the pressure in the foot support bladder 1710 and the fluid reservoir 1720 as fluid moves from the foot support bladder 1710 into the fluid reservoir 1720. This action causes... Figure 20B The configuration shown to Figure 20A The configuration change is shown. Therefore, this movement of the fluid (opening of fluid line 1766) will result in: (i) an increase in the height dimension of fluid storage chamber 1720 and / or refilling of fluid storage chamber 1720 (when fluid returns to it), and / or (ii) an increase in the height dimension of the entire sole structure 200 and / or footwear 250. (The last sentence appears to be incomplete and possibly refers to H2 and H4.) Figure 20B ) respectively with H1 and H3 ( Figure 20A (Compare)

[0122] In some instances of this technology, opening the fluid line 1766 can cause a rapid transfer of fluid from the foot support bladder 1710 to the fluid reservoir 1720, as the pressure difference (the higher pressure in the foot support bladder 1710) and the open fluid line 1766 will cause the system to equalize the pressure. This rapid transition from a higher-pressure foot support configuration to a lower-pressure foot support configuration can be perceived by the wearer in at least two ways. Specifically: (i) the wearer can feel the foot support bladder 1710 becoming softer (as its pressure decreases), (ii) the wearer can feel a perceptible “bulge” as the height dimension of the fluid reservoir 1720 increases, and / or (iii) the wearer (or others) can visually see a perceptible change in height dimension. For example, depending on the size of the fluid line 1766, these perceptible changes can occur substantially instantaneously when the fluid line 1766 is opened (e.g., within less than one or two seconds).

[0123] The height difference between H1 and H2 (where in the illustrated example, H1 is greater than H2) may be within any one or more of the following ranges: at least 3 mm; at least 5 mm; at least 8 mm; at least 10 mm; at least 12 mm; at least 15 mm; at least 20 mm; between 3 mm and 35 mm; between 3 mm and 30 mm; between 3 mm and 25 mm; between 5 mm and 35 mm; between 5 mm and 30 mm; between 5 mm and 25 mm; between 8 mm and 35 mm; between 8 mm and 30 mm; between 8 mm and 25 mm; between 10 mm and 35 mm; between 10 mm and 30 mm; and / or between 10 mm and 25 mm. Any one or more of these same height difference ranges may also be provided between H3 and H4 (where in the illustrated example, H3 is greater than H4).

[0124] Combined on the above Figures 1A to 20B In the described examples, the fluid system (100, 1700), sole structure (200), and footwear article (250) include physical or hard-switching components 900, 1740 with which a user interacts to change certain fluid lines (e.g., fluid lines 504 and / or 1766) between open and closed configurations (and / or to change the foot support system 100, 1700 between a higher pressure foot support configuration and a lower pressure foot support configuration).

Figure 21B ) and 2150 ( Figure 21C Examples and characteristics of the electronic control system 2102, which is configured to cause the fluid line 504 ( Figure 21B ) or fluid pipeline 1766 ( Figure 21C The system can change between open and closed configurations. Using such an electronic control system 2102, as will be explained in more detail below, the user can change the sole structure 200 and / or footwear 2180 (see...). Figure 21A It changes between a higher-pressure foot support configuration and a lower-pressure foot support configuration. Figures 21A to 23B Used with Figures 1A to 20B In cases where the same reference numerals are used, the same or similar parts (including any options or alternatives described herein for those parts) shall be referenced, and many overlapping descriptions may be omitted.

[0125] Figure 21A The diagram illustrates the relationship with Figure 2A The view of footwear article 250 shown is similar to the outer view of footwear article 2180. Footwear article 2180 includes an upper 202 and a sole structure 200 engaged with the upper 202. Figure 21A Only a portion of the upper 202 is shown in dashed lines, but the upper 202 may include any desired materials, components, number of components, construction, structure, etc., without departing from the present technology, including conventional materials, components, number of components, construction, structure, etc., known and used in the footwear industry. The upper 202 may be joined to the sole structure 200 in any desired manner, including by using one or more of adhesives, stitching, or mechanical fasteners, including in manner conventionally known and used in the footwear industry.

[0127] Figure 21B Various example components of a fluid system 2100 according to some embodiments of the present technology are schematically illustrated. Generally, the fluid system 2100 is structurally and functionally similar to the above-described combinations, for example. Figures 1A to 16C The described fluid system 100, except that fluid system 2100 includes an electronic control system 2102 for opening and closing fluid lines 504 (which selectively allows fluid to be transferred between fluid storage chamber 500 and foot support bladder 400). The electronic control system 2102 may include one or more input devices 2104 for receiving user input (and / or other inputs). Although Figure 21B An antenna is shown as input device 2104, but additional or alternative input devices may be provided, including one or more of the following: keyboard, mouse or other pointing device, touch screen, button, joystick, USB port, other connector or plug port, etc.

[0128] The electronic control system 2102 may further include a processing system 2106 (e.g., having one or more microprocessors) for receiving input data, performing operations on the input data, and generating output data. Output data (e.g., as electronic signals) may be transmitted via one or more input / output ports 2108 to control a switch or valve 2110 that interacts with fluid flow in the fluid line 504 in some way (e.g., as described in more detail below). The input / output ports 2108 may also be used to enable the processing system 2106 to receive input from the electronically controllable switch or valve 2110 (e.g., to provide the processing system 2106 with "open / closed" status information, fluid flow information, fluid pressure information, etc.). Any type of input / output port 2108 may be provided, such as a USB port, a socket or plug component, a wireless transceiver, etc. Electronic communication between the electronic control system 2102 and the electronically controllable switch or valve 2110 may be performed in any desired manner and using any desired communication system and / or protocol.

[0129] Figure 21B The example electronic control system 2102 is also shown communicating electronically with a computing system 2120, such as a mobile computing device (e.g., a smartphone or other cellular phone, laptop computer, tablet computer, etc.). Although in Figure 21B The illustration depicts wireless communication between the computing system 2120 and the electronic control system 2102 (e.g., using Bluetooth Low Energy (BLE) systems and protocols, infrared communication, etc.), but any desired type of electronic communication (wired or wireless) can be used in other specific instances of this technology. The computing system 2120: (a) can receive user input and / or other types of user input indicating a desired change and / or control of the pressure in the foot support bladder 400; (b) can transmit the user input to the electronic control system 2102 (note: transmission icon 2122); and / or (c) can receive data or other information from the electronic control system 2102.

[0130] Figure 21B The electronic control system 2102 can be operated to open and close the fluid line 504, for example, as described above. Figures 1A to 16C The structure shown describes the following. In this way, the foot support bladder 400 can be changed between (a) a higher pressure foot support configuration when the electronically controlled switch or valve 2110 is open and (b) a lower pressure foot support configuration when the electronically controlled switch or valve 2110 is closed (which allows fluid to move from the foot support bladder 400 to the storage chamber 500 using the pump 550).

[0131] Figure 21CVarious example components of a fluid system 2150 according to some embodiments of the present technology are schematically illustrated. Generally, the fluid system 2150 is structurally and functionally similar to the above-described combinations, for example... Figures 17A to 20B The described fluid system 1700, except that fluid system 2150 includes an electronic control system 2102 for opening and closing fluid lines 1766 (which selectively allows fluid to be transferred between fluid storage chamber 1720 and foot support bladder 1710). The electronic control system 2102 may include one or more input devices 2104 for receiving user input (and / or other inputs). Although Figure 21C An antenna is shown as input device 2104, but additional or alternative input devices may be provided, including one or more of the following: keyboard, mouse or other pointing device, touch screen, button, joystick, USB port, other connector or plug port, etc.

[0132] Similar to Figure 21B Examples, Figure 21C The electronic control system 2102 may also include a processing system 2106 (e.g., having one or more microprocessors) for receiving input data, performing operations on the input data, and generating output data. Output data (e.g., as electronic signals) may be transmitted via one or more input / output ports 2108 to control a switch or valve 2110 that interacts with fluid flow in the fluid line 1766 in some way (e.g., as described in more detail below). The input / output ports 2108 may also be used to enable the processing system 2106 to receive input from the electronically controllable switch or valve 2110 (e.g., to provide the processing system 2106 with "open / closed" status information, fluid flow information, fluid pressure information, etc.). Any type of input / output port 2108 may be provided, such as a USB port, a socket or plug component, a wireless transceiver, etc. Electronic communication between the electronic control system 2102 and the electronically controllable switch or valve 2110 may be performed in any desired manner and using any desired communication system and / or protocol.

[0133] Figure 21C The example electronic control system 2102 is also shown communicating electronically with a computing system 2120, such as a mobile computing device (e.g., a smartphone or other cellular phone, laptop computer, tablet computer, etc.). Although in Figure 21CThe diagram illustrates wireless communication between the computing system 2120 and the electronic control system 2102 (e.g., using Bluetooth Low Energy (BLE) systems and protocols, infrared communication, etc.), but any desired type of electronic communication (wired or wireless) can be used in other specific instances of this technology. The computing system 2120: (a) can receive user input and / or other types of user input indicating a desired change and / or control of the pressure in the foot support bladder 400; (b) can transmit the user input to the electronic control system 2102 (note: transmission icon 2122); and / or (c) can receive data or other information from the electronic control system 2102.

[0134] Figure 21C The electronic control system 2102 can be operated to open and close the fluid line 1766, for example, as described above. Figures 17A to 20B The structure shown describes the following. In this way, the foot support bladder 1710 can be switched between (a) a higher pressure foot support configuration when the electronically controlled switch or valve 2110 is closed (which allows fluid to be moved from the fluid storage chamber 1720 to the foot support bladder 1710 using the pump 1730) and (b) a lower pressure foot support configuration when the electronically controlled switch or valve 2110 is open.

[0135] Figure 21D The illustrations illustrate examples of various functions and / or information that can be presented to a user on a graphical user interface 2124 or a display screen according to some examples of the present technology, which can be provided to a user 2126 on a computing device 2120. The graphical user interface 2124 can be used to allow a user to supply input data to an electronic control system 2102 to control an electronically controllable switch or valve 2110. The example application and its graphical user interface 2124 screen provide the user 2126 with: (a) the ability to open / close the system (soft button 2120P); (b) the ability to increase foot support pressure or set the foot support pressure to a higher foot support pressure configuration (soft button 2128); and (c) the ability to decrease foot support pressure or set the foot support pressure to a lower foot support pressure configuration (soft button 2130). The graphical user interface 2124 screen of this example also includes soft buttons 2132L, 2132R to switch between the graphical user interface screens 2124 for the left and right shoes in a pair of shoes, and one or more indicators 2132I regarding which shoe is being displayed. Additionally, the graphical user interface 2124 screen of this example includes shortcut keys (soft buttons 2134) to allow the user to match the settings of one shoe with those used on the other shoe. The "Settings" soft button 2136 allows the user to access, control, and / or change various setting functions of the fluid systems 2100, 2150 (e.g., adjusting the maximum pressure setting, adjusting the minimum pressure setting, adjusting display functions, etc.).

[0136] The example fluid systems 2100 and 2150 described above allow for electronic control of foot support pressure between two discontinuous pressure configurations (a higher foot support pressure configuration and a lower foot support pressure configuration). Other options are also possible. For example, an electronic control system 2102 could also be used (e.g., by additionally controlling one or more of valves 114 and 118). Figure 21B ), one or more of valves 1750 and 1752 ( Figure 21C (and / or one or more other footwear and / or fluid system components) to maintain the fluid pressure in the foot support bladder 400, 1710 at a desired pressure between a maximum pressure setting and a minimum pressure setting. One or more pressure sensors (e.g., 2102P, see...) Figure 21B and Figure 21C It can be located in the foot support bladder 400, 1710 (or other locations) to provide information (data) about the fluid pressure in the foot support bladder 400, 1710 to the electronic control system 2102 and for pressure control functions. Figure 21E and Figure 21F An example of a graphical user interface 2124 screen that can be used to operate such a fluid system is shown. Figure 21E and Figure 21F Used with Figure 21D In cases where the same reference numerals are used, the same or similar functions and / or features (including any options or alternatives discussed above) are referred to, and many overlapping descriptions may be omitted.

[0137] Figure 21E An example graphical user interface 2124 screen for the left shoe in a pair of shoes is shown, and Figure 21F An example graphical user interface 2124 screen corresponding to the right shoe in this pair of shoes is shown. In addition to the above, for... Figure 21D In addition to the features and functions described in the graphical user interface 2124, Figure 21E and Figure 21F Examples include several additional features that allow the user 2126 to selectively set the desired pressure for the foot support bladders 400 and 1710. For example, Figure 21E and Figure 21FA pressure selection system 2140 is shown, which allows the user to: (a) select the highest pressure setting (soft button 2128); (b) select the lowest pressure setting (soft button 2130); (c) increase the pressure setting by one unit (or by one unit per press) (soft button 2142); and (d) decrease the pressure setting by one unit (or by one unit per press) (soft button 2144). Additionally or alternatively, the "press and hold" action of soft buttons 2142 and / or 2144 can be used to increase or decrease the pressure setting by more than one unit (e.g., the longer buttons 2142 / 2144 are held down, the greater the change in pressure setting). Changes in pressure setting may be accompanied by changes in pressure setting displayed in area 2146 (e.g., area 2146 may include a numerical display and / or indicator 2148A located on a sliding scale 2148B). Additionally or alternatively, in at least some instances of this technology, if desired, pressure setting changes can be achieved by the user 2126 pressing the indicator 2148A and sliding it up or down along the sliding scale 2148B. Pressure readings obtained by the pressure sensor 2102P can be used by the electronic control system 2102 to adjust the pressure in the foot support bladders 400, 1710 to the desired and selected level.

[0138] Figure 21E and Figure 21F Additional potential soft buttons on these example graphical user interface 2124 screens are shown. For example, soft button 2138A in this example constitutes a "previous" (or "back") button, for example, to allow user 2126 to go back to the immediately preceding pressure setting and / or undo the immediately preceding action. In this example, soft buttons 2138B and 2138C provide other desired functions, such as shortcut buttons for two "favorite" pressures or settings. Additionally or alternatively, soft buttons 2138B and 2138C can be designed to be selectively programmed by user 2126 for any desired function (e.g., programmed by user 2126 via "Settings" button 2136 to have any desired function selected from the list of available functions).

[0139] The diagram Figure 21E and Figure 21F Examples show the use of shoes for the left foot ( Figure 21E ) and right shoe ( Figure 21F The graphical user interface 2124 screen. In some instances of this technology, the user can switch between these screens using buttons 2132L and 2132R. Figure 21E and Figure 21F The diagram also illustrates that the left and right shoes of a pair of shoes do not need to have the same desired pressure settings. Note the difference in pressure settings shown at section 2146 in both diagrams.

[0140] As described above, in some instances of this technology, soft buttons 2138B and / or 2138C can be selectively programmed to provide any desired functionality. In some more specific instances of this technology, soft buttons 2138B and / or 2138C can be pre-programmed to place footwear 2180 in one or more settings for: playing games (e.g., video games); participating in specific sports or activities; etc. Additionally or alternatively, if desired, soft buttons 2138B and / or 2138C can launch programs on computing system 2120 (e.g., launching a video game application to start playing a video game) and / or can launch performance monitoring applications on computing system 2120 (e.g., programs that measure athletic performance metrics associated with sports, such as running record applications that track one or more of running time, location, route, pace, etc.; other sports tracking / metric measurement programs; etc.).

[0141] Additionally or alternatively, the electronic control system 2102 according to at least some embodiments of the present technology can receive input data from one or more force sensors 2170, for example, such as Figure 21E and Figure 21F As shown. This type of force sensor 2170 can be installed in shoe 2172 (in... Figure 21E and Figure 21F (Illustrated schematically), and optionally for multiple locations on the foot (e.g., one or more of the heel, forefoot, medial, lateral, etc.), data regarding the contact between the foot and the ground or other contact surfaces, the contact force between the foot and the ground or other contact surfaces, etc., are provided to the electronic control system 2102 (via wired or wireless connection). This foot contact and / or force data can be used as input to set, change, or control the fluid pressure in the foot support bladders 400, 1710. Foot force sensors incorporated into this type of sole structure and / or footwear article are known, for example, as shown in U.S. Patent Nos. 9,756,895 B2 and 9,743,861 B2, each of which is incorporated herein by reference in its entirety. In this way, in at least some instances of the present technology, the foot support pressure in the foot support bladders 400, 1710 can be changed automatically, for example, in response to foot contact force data.

[0142] As described above, in at least some aspects of this technology, the height dimensions of the sole structure 200 (e.g., the height dimensions of one or more of the fluid reservoirs 500, 1720 and / or foot support bladders 400, 1710) can be varied according to a selected pressure setting. Using these features, as another alternative, one or more of the soft buttons 2138B and / or 2138C can be pre-programmed to position the sole structure 200 (e.g., one or more of the fluid reservoirs 500, 1720 and / or foot support bladders 400, 1710) at a pre-selected height setting, if desired. In addition to the maximum height setting (e.g., when fluid line 1766 is open) and the minimum height setting (e.g., when fluid line 1766 is closed and fluid reservoir 1720 is substantially depleted of fluid), the electronic control system 2102 can be controlled to move fluid between fluid reservoirs 500, 1720 and foot support bladders 400, 1710 to achieve one or more intermediate pressures between the maximum and minimum pressure settings, such that the height dimension can be controlled to a height between the maximum and minimum height settings. Additionally or alternatively, in at least some instances of this technology, one or more of soft buttons 2138B and / or 2138C can be pre-programmed to place the sole structure 200 (e.g., foot support bladders 400, 1710) at a pre-selected pressure setting. In addition to the highest pressure setting (e.g., when fluid line 504 is open or when fluid line 1766 is closed) and the lowest pressure setting (e.g., when fluid line 504 is closed or when fluid line 1766 is open), the electronic control system 2102 can be controlled to move fluid between fluid storage chambers 500, 1720 and foot support bladders 400, 1710 to achieve one or more intermediate pressures between the highest and lowest pressure settings (with or without changes in height dimension).

[0143] Changing height and / or pressure settings and / or using pre-programmed height and / or pressure settings (e.g., using buttons 2138B and / or 2138C) can be used for personal preference, comfort, customization, and / or other purposes (e.g., regarding gameplay or other applications (e.g., sports performance monitoring applications)). As some more specific examples, pre-programmed height and / or pressure setting features can be used when playing different dance games. In breakdancing games, users typically want the shoes to be softer and / or more stable at a lower height to allow for easier foot flexion and / or provide a softer feel. On the other hand, in tap dancing games, users typically want a firmer setting to perform tap movements. Pre-programmable buttons 2138B, 2138C can be used as shortcut keys to set the pressure level for the desired type of dance, and / or force sensor 2170 can provide input data and / or measurement information about foot contact, foot contact location, and foot contact force experienced during these activities, and / or provide data for display in the game.

[0144] As an additional example, gamers may want different settings for different avatars, for instance, to better match the characteristics of the shoes 2172 with the characteristics of the avatar. Some characters can be configured to move very steadily, while others can move with more bouncy steps. Different height and / or pressure settings in the shoes 2172 can help players better execute the character's movement characteristics. Preprogrammable buttons 2138B and 2138C can be used as shortcut keys, such as selecting a specific avatar and / or movement style for the game, and / or force sensor 2170 can provide input data and / or measurement information about the user's movement during these activities, and / or provide data for display in the game.

[0145] As other, more specific examples, as described above, in some instances of this technology, pressure and / or height changes can occur incrementally, for example, gradually. In some instances of this technology, games or applications can utilize this feature, for example, so that when a user moves from one character and / or world to another within a game environment, the user can feel a shift in their footing. In instances of this technology where pressure and / or height changes occur instantaneously (e.g., when fluid line 1766 is opened), game applications or programs can use this feature as a result of some achievement or feature within the game. For example, if a user's character (e.g., in a video game) reaches a certain level or achieves a certain goal, the application can trigger an electronic control system 2102 to increase the height dimension of the sole structure 200, so that the user can physically feel as if they have become taller (optionally accompanied by an increase in the height of the avatar within the game display). Then, as the game progresses further, the height dimension can decrease slowly or incrementally, so that when the next level is reached or the goal is achieved, the user can experience another height increase "reward." These types of interactive game features are well-suited for virtual reality games and game systems.

[0146] As described above, the electronic control system 2102 may include (e.g., controllable or operable) an electronically controllable valve or switch 2110 that causes fluid lines 504 and / or 1766 to change between open and closed configurations. Various configurations can be used to open and close the electronically controllable valve or switch 2110, which will be discussed below. Figures 22 to 23B Describe some instances of this structure.

[0147] Figure 22 An example of switch 2110A of electronically controllable valve or switch 2110 is shown. Figure 22The left side shows switch 2110A positioned such that fluid lines 504, 1766 are in an open configuration, allowing fluid to flow between foot support bladders 400, 1710 and fluid storage chambers 500, 1720. As discussed above, in some instances of this technology, fluid lines 504, 1766 may be positioned within the fluid line support area 604B of the fluid line support surface 604 of the support member 600 and in contact with the outer surface 700A of the tube closure member 700. When switch 2110A is in the open configuration, the closing element 2110C of switch 2110A is positioned adjacent to (or possibly in contact with) fluid lines 504, 1766. In use, at a certain point in time, electronic control system 2102 will send a signal to switch 2110A to close fluid lines 504, 1766. Such signals will drive the movement of the closing element 2110C (e.g., by activating a motor to generate translational, rotational, etc., movement of the closing element 2110C) to physically clamp and close the fluid lines 504 and 1766, such as... Figure 22 As shown on the right-hand side. Additionally, in use, at a certain point in time, the electronic control system 2102 will send a signal to switch 2110A to open fluid lines 504, 1766. This signal will drive the movement of closing element 2110C (e.g., by activating a motor to produce translational, rotational, etc., movement of closing element 2110C) to retract it away from fluid lines 504, 1766, thereby allowing fluid lines 504, 1766 to open, as... Figure 22 As shown on the left side. At least this portion of fluid lines 504 and 1766 will be made of a collapseable material such as a flexible elastomer tube to allow it to collapse into a closed configuration and return to an open configuration.

[0148] Figure 23A An example of valve 2110B of electronically controllable valve or switch 2110 is shown. In this example, valve 2110B is shown directly within fluid lines 504, 1766, although it may be located in a component (e.g., another fluid line) in fluid communication with fluid lines 504, 1766. Figure 23A The top shows valve 2110B, which is positioned such that fluid lines 504, 1766 are in an open configuration, allowing fluid to flow between foot support bladders 400, 1710 and fluid storage chambers 500, 1720. In this open configuration, magnet 2302 is positioned near valve 2110B such that the magnetic force applied to movable valve part 2306 (made of a magnet or a material attracted by a magnet) (see arrow 2304) is strong enough to overcome the biasing force of biasing member 2312 (e.g., a spring) and pull movable valve part 2306 away from fixed valve part 2308 and away from valve seat region 2310. This opens the fluid path through valve 2110B, as... Figure 23A The fluid flow arrow at the top indicates this. In this way, the fluid can flow: (i) through fluid line 504 (e.g., in...). Figure 21B In the example, from the fluid storage chamber 500 to the foot support bladder 400) or (ii) through the fluid line 1766 (e.g., in Figure 21C Examples range from the foot support bladder 1710 to the fluid storage chamber 1720.

[0149] During operation, at a certain point in time, the electronic control system 2102 will send a signal to close fluid lines 504 and 1766. This signal will drive the movement of magnet 2302 (e.g., by activating a motor to generate translational, rotational, or other motion of magnet 2302) to a position further away from the movable valve component 2306, such as... Figure 23A As shown at the bottom, when magnet 2302 moves away from movable valve part 2306, the magnetic force acting on movable valve part 2306 will no longer be sufficient to overcome the force of bias member 2312. At this time, the biasing force from bias member 2312 (see arrow 2314) will cause movable valve part 2306 to move against the seat region 2310 of fixed valve part 2308, thereby closing the fluid path through valve 2110B. In this closed configuration, fluid may no longer flow through fluid line 504 (in Figure 21B In the example) or flow through fluid line 1766 (in Figure 21C In an example (as in the example). Additionally, during use, at a certain point in time, the electronic control system 2102 will send a signal to open fluid lines 504, 1766. Such a signal will drive the movement of magnet 2302 (e.g., by activating a motor to generate translational, rotational, etc., motion of magnet 2302) back to the "closed" position (e.g., as in the example). Figure 23A (As shown at the top). This action will counteract the biasing force of the bias member 2132, pulling the movable valve part 2306 back from the valve seat region 2310 to allow fluid lines 504, 1766 to open, as shown. Figure 23A As shown at the top.

[0150] Figure 23B An example of another valve 2110D of the electronically controllable valve or switch 2110 is shown. In this example, valve 2110D is shown directly within fluid lines 504, 1766, although it may be located in a component (e.g., another fluid line) in fluid communication with fluid lines 504, 1766. Figure 23BThe top shows valve 2110D, which is positioned such that fluid lines 504, 1766 are in an open configuration, allowing fluid to flow between foot support bladders 400, 1710 and fluid storage chambers 500, 1720. In this open configuration, magnet 2302 is positioned near valve 2110D such that the magnetic force applied to movable valve part 2306 (in this example, a ball made of a magnet or a material attracted by a magnet) (see arrow 2304) is strong enough to overcome the biasing force of biasing member 2312 (e.g., a spring) and pull movable valve part 2306 away from fixed valve part 2308 and away from valve seat region 2310. This opens the fluid path through valve 2110D, as... Figure 23B The fluid flow arrow at the top indicates this. In this way, the fluid can flow: (i) through fluid line 504 (e.g., in...). Figure 21B In the example, from the fluid storage chamber 500 to the foot support bladder 400) or (ii) through the fluid line 1766 (e.g., in Figure 21C Examples range from the foot support bladder 1710 to the fluid storage chamber 1720.

[0151] During operation, at a certain point in time, the electronic control system 2102 will send a signal to close fluid lines 504 and 1766. This signal will drive the movement of magnet 2302 (e.g., by activating a motor to generate translational, rotational, or other motion of magnet 2302) to a position further away from the movable valve component 2306, such as... Figure 23B As shown at the bottom, when magnet 2302 moves away from movable valve part 2306, the magnetic force acting on movable valve part 2306 will no longer be sufficient to overcome the force of bias member 2312. At this time, the biasing force from bias member 2312 (see arrow 2314) will cause movable valve part 2306 to move against the seat region 2310 of fixed valve part 2308, thereby closing the fluid path through valve 2110D. In this closed configuration, fluid may no longer flow through fluid line 504 (in Figure 21B In the example) or flow through fluid line 1766 (in Figure 21C In an example (as in the example). Additionally, during use, at a certain point in time, the electronic control system 2102 will send a signal to open fluid lines 504, 1766. Such a signal will drive the movement of magnet 2302 (e.g., by activating a motor to generate translational, rotational, etc., motion of magnet 2302) back to the "closed" position (e.g., as in the example). Figure 23B (As shown at the top). This action will allow fluid lines 504 and 1766 to open, as shown. Figure 23B As shown at the top.

[0152] Figure 22 A to Figure 23BThe valves 2110B and 2110D of the types illustrated and the features of their potential operation are illustrated and described in U.S. Provisional Patent Application No. 62 / 678,635, filed May 31, 2018, and U.S. Patent No. 11,147,342 B2, granted October 19, 2021. Any valve described in U.S. Provisional Patent Application No. 62 / 678,635 and U.S. Patent No. 11,147,342 B2 can be used in various aspects of the present art. U.S. Provisional Patent Application No. 62 / 678,635 and U.S. Patent No. 11,147,342 B2 are incorporated herein by reference in their entirety.

[0153] In other specific embodiments of this technology, other types of valves may be used instead of valves 2110B and / or 2110D.
