[0028] Although some of the operations of the disclosed methods are described in a specific order for ease of presentation, it should be understood that this descriptive approach encompasses rearrangement unless the specific language used below requires a particular order. For example, operations described in sequence may be rearranged or performed simultaneously in certain situations. Furthermore, for simplicity, the accompanying drawings may not show the various ways in which the disclosed things and methods can be used in conjunction with other things and methods. Additionally, the description sometimes uses terms such as “provide,” “generate,” “determine,” and “select” to describe the disclosed methods. These terms are high-level descriptions of the actual operations performed. The actual operations corresponding to these terms will vary depending on the specific implementation and will be readily discernible by those skilled in the art who benefit from this disclosure.

[0029] For the purposes of this disclosure, when footwear is worn on a properly sized foot, the various parts (and their components) of the footwear can be identified based on the area of ​​the foot located at or near that part of the footwear. For example, footwear and / or sole construction can be considered to have a “forefoot area” at the front of the foot, a “midfoot” area at the middle or arch region of the foot, and a “heel area” at the rear of the foot. Footwear and / or sole construction also includes a “lateral” (the “outer” or “little toe” side of the foot) and a “medial” (the “inner” or “big toe” side of the foot). The forefoot area typically includes the portion of the footwear corresponding to the toe and the joint connecting the metatarsals and phalanges. The midfoot area typically includes the portion of the footwear corresponding to the arch region of the foot. The heel area typically corresponds to the rear portion of the foot, including the calcaneus. The outer and inner sides of the footwear extend through the forefoot, midfoot, and heel areas and generally correspond to the opposite sides of the footwear (and can be considered to be separated by a central longitudinal axis). These areas and sides are not intended to delineate precise regions of the footwear. Rather, the terms “forefoot,” “midfoot,” “heel,” “outer side,” and “inner side” are intended to refer to the general areas of footwear articles and their various components to aid in the discussion below.

[0030] For the purposes of this disclosure, directional adjectives corresponding to the illustrated examples may be used. For example, the term "longitudinal" as used herein refers to the direction extending the length of the article. In some cases, the longitudinal direction may extend from the forefoot portion of the article to the heel portion. Furthermore, the term "lateral" as used herein refers to the direction extending the width of the article. In other words, the lateral direction may extend between the inside and outside of the article. Additionally, the term "vertical" as used herein refers to a direction substantially perpendicular to both the lateral and longitudinal directions. For example, when the article is laid flat on a ground surface, the vertical direction may extend upwards from the ground surface. It should be understood that each of these directional adjectives may be applied to an individual component of the article, such as the upper and / or sole structure.

[0031] As used herein, the term "exemplary" means used as a non-limiting instance, example, or illustration. As used herein, the term "for example" (eg / for example) introduces a series of one or more non-limiting instances, examples, and / or illustrations.

[0032] As used herein, the term “sole construction” refers to any combination of materials that provide support for the wearer’s foot and bear the surface in direct contact with the ground or sports surface, such as, for example, a single sole; a combination of outsole and insole; a combination of outsole, midsole and insole; and a combination of overlay, outsole, midsole and insole.

[0033] As used herein, the terms “attachment” and “connection” generally mean a physical connection or link, including objects that are directly attached / connected and objects that are attached / connected by an intermediate element between the attached / connected objects, unless otherwise expressly stated to the contrary.

[0034] As used herein, the term "footwear products" or "products" means any type of footwear, including, for example, basketball shoes, volleyball shoes, tennis shoes, running shoes, football shoes, rugby shoes, rugby shoes, baseball shoes, athletic shoes, hiking boots, sandals, socks, etc.

[0035] Although the accompanying drawings may illustrate footwear intended for use on only one of the wearer's feet (e.g., the right foot), those skilled in the art who benefit from this disclosure will recognize that the corresponding footwear for the other foot (e.g., the left foot) will be a mirror image of the right footwear.

[0036] Unless otherwise explained, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure pertains. While similar or equivalent methods and materials to those described herein may be used in practice or testing of this disclosure, suitable methods and materials are described below. These materials, methods, and examples are illustrative only and are not intended to be limiting. Other features of this disclosure will become apparent from the detailed description, claims, abstract, and drawings.

[0037] The disclosed technology Footwear typically comprises two main components: the sole structure and the upper. The sole structure is configured to support the wearer's foot and provide cushioning between the wearer's foot and the ground (e.g., the surface on which they are moving, walking, running, etc.). The upper is attached to the sole structure and forms a foot-receiving cavity. The upper is configured to secure the wearer's foot to the sole structure and / or to protect the wearer's foot.

[0038] In some instances, the upper may include a strobel, and the footwear may include an insole disposed inside the upper and abutting against the strobel. In some instances, the insole may also be referred to as an insole.

[0039] While insoles can be designed to provide increased cushioning and support to the wearer's foot, they can also beneficially provide tactile feedback and / or enhance the sensation to the bottom of the wearer's foot.

[0040] This document discloses footwear articles comprising an insole (or insole) that provides tactile feedback or enhanced tactile sensation to the sole of the foot of a person wearing the footwear article (“wearer”). For example, the insole may include features that provide a tactile response to the wearer’s foot as the wearer applies weight to the insole and moves along a ground surface. In some instances, the insole may be configured to enhance positional awareness and / or provide a fun and / or stimulating sensation to the wearer’s foot through insole stimulation (such as upward thrust).

[0041] More specifically, this document describes an insole that may include one or more layers, the layers comprising a sheet configured as a single sheet including a plurality of arches spaced apart from each other and interconnected by a connecting portion of the sheet. Each arch is deflectable from a first state to a second state in which at least the peak of the arch faces inward toward the interior of the footwear (e.g., toward the wearer's foot when the footwear is worn by an individual) and protrudes away from the connecting portion (along a first direction), and in the second state in which at least the peak faces toward the remainder of the sole structure and protrudes away from the connecting portion (along a second direction). In response to a force applied to the arch (e.g., from the wearer pressing on the arch or applying weight to the arch), each arch is configured to deflect from the first state to the second state. When the force is removed (e.g., when the wearer removes weight from that portion of the insole, such as when lifting their foot off the ground), the arch rapidly springs back from the second state to the first state.

[0042] In some instances, the wearer may experience two tactile sensations. The first sensation may be a tactile snap-on sensation, which arises when one or more arches are pressed into the remainder of the insole and away from the interior of the footwear (and the wearer's foot). The second sensation may be a second tactile or snap-on sensation, which arises when the one or more arches spring back to their original state (the first state) when unloaded.

[0043] The bottom (or sole) of the foot is highly sensitive. Therefore, the arch of this insole can transmit tactile sensations to the wearer's foot, providing enhanced feeling and perception. In some instances, this can allow the wearer to maintain focus during activity (such as by providing a stress-relieving tool). Wearing footwear that includes such an insole can also be fun and offer new experiences not found in footwear that does not provide this targeted tactile response. In some instances, such insoles can be used in footwear for athletic training. For example, such insoles can be worn by athletes to allow them to understand how their feet bear weight during certain athletic activities, such as various sports.

[0044] In some instances, the insole for footwear comprises a sheet including a plurality of arches spaced apart from each other and interconnected by a connecting portion of the sheet. The connecting portion extends between adjacent arches and around each arch. Each arch is deflectable from a first state to a second state in which at least the peak of the arch protrudes along a first direction away from the connecting portion, and in the second state in which at least the peak protrudes along a second direction away from the connecting portion, wherein the first direction faces the interior of the footwear.

[0045] In some instances, the insole for footwear includes a first layer and a second layer. The first layer includes a plurality of arches spaced apart from each other, and the second layer is positioned adjacent to the first layer. The second layer includes a plurality of openings spaced apart from each other. Each arch of the first layer is aligned with a corresponding opening among the plurality of openings in the second layer. Each arch has an undeflected state and a deflected state, in which the arch protrudes outward and away from the corresponding opening, and in which the arch extends into the corresponding opening.

[0046] In some examples, the insole for footwear includes a first layer comprising a plurality of spaced-apart arches formed therein. Each arch is movable between a raised shape and a recessed shape relative to the inward-facing side of the first layer facing the interior of the footwear. The first layer comprises an elastic polymer such that each arch can move from the raised shape to the recessed shape under load and return to the raised shape when the load is removed. The insole also includes a second layer comprising foam. The second layer is disposed on the inward-facing side of the first layer. The second layer conforms to the contours of the plurality of spaced-apart arches.

[0047] In some instances, the insole for footwear includes a first layer and a second layer. The first layer includes a plurality of first arches spaced apart from each other, and the second layer is positioned adjacent to the first layer. The second layer includes: a plurality of second arches spaced apart from each other, each second arch aligned with a corresponding first arch among the plurality of first arches; a connecting portion extending between and around the plurality of second arches; and a plurality of orifices extending through the thickness of the connecting portion, wherein each second arch is surrounded by one or more of the plurality of orifices, the one or more orifices defining a corresponding cavity located beneath the second arch and having a depth defined by the thickness of the connecting portion. Each aligned first and second arch has an undeflected state and a deflected state. In the undeflected state, the first and second arches protrude outward and away from the corresponding cavity, and in the deflected state, the first and second arches extend into the corresponding cavity.

[0048] In some examples, the insole for footwear includes a first layer comprising a plurality of spaced-apart first arches formed therein, wherein each first arch is movable between a raised shape and a recessed shape relative to the inward-facing side of the first layer facing the interior of the footwear, and wherein the first layer comprises an elastic polymer such that each first arch can move from the raised shape to the recessed shape under load and return to the raised shape when the load is removed. The insole includes a second layer comprising a connecting portion and a plurality of spaced-apart second arches, wherein each second arch is connected to the connecting portion by one or more connecting portions defined by one or more openings spaced around the periphery of the second arch, wherein the one or more openings extend through the thickness of the connecting portion and define a corresponding cavity located beneath the second arch, and wherein each second arch is aligned with a corresponding first arch among the plurality of first arches and is movable together with the corresponding first arch between a raised shape and a recessed shape relative to the inward-facing side of the connecting portion of the second layer facing the first layer. Each corresponding first dome and second dome is configured to extend into the corresponding cavity in its concave shape, and wherein the second layer is configured to attenuate sound as each first dome moves between the convex shape and the concave shape.

[0049] Additional examples of the disclosed technology are described below with reference to the accompanying drawings.

[0050] Examples of the disclosed technologies Figures 1 to 4 It shows products for footwear (such as) Figure 11The footwear product 400 shown (described further below) includes an insole 100. The insole 100 may include one or more layers. In some instances, such as... Figures 1 to 4 As shown, the inner bottom 100 comprises multiple stacked layers. Figure 1 A perspective view of the assembled insole 100 is shown. Figure 2 A cross-sectional side view of the assembled inner bottom 100 is shown, and Figure 4 An exploded view of the insole 100 is shown. Figure 3A It shows Figure 2 A detailed view of a selected portion 101 of the cross-sectional view.

[0051] As used herein, the “inward-facing surface” or “inward-facing side” of a layer (or sheet) can be the surface or side facing the interior of the footwear (e.g., a cavity formed by the upper) and the wearer’s foot when the footwear is being worn. Accordingly, in some instances, the inward-facing surface may alternatively be referred to as the foot-facing surface. The “outward-facing surface” or “outward-facing side” of a layer (or sheet) can be the surface or side facing away from the interior of the footwear and towards the rest of the sole structure (such as the outsole). Thus, when the footwear is being worn, the “outward-facing surface” or “outward-facing side” of the layer may face the ground surface. Accordingly, in some instances, the outward-facing surface may be referred to as the ground-facing surface.

[0052] The inner bottom 100 includes a first layer 102, which includes a plurality of vaults 112 spaced apart from each other on the first layer 102 (e.g., Figure 4 (As shown). The first layer 102 also includes a connecting portion 114 that extends between and around the plurality of vaults 112. The connecting portion 114 may be continuous. In some instances, the connecting portion 114 may be referred to as being formed by a plurality of connecting segments that are continuous on the first layer 102.

[0053] In this way, each vault 112 can be surrounded by the connecting portion 114 (e.g., completely surrounded around its perimeter) (unless the vault 112 is formed at the edge of the first layer 102, in which case the inner side or edge of the vault is surrounded by the connecting portion 114).

[0054] The first layer 102 may also be referred to as a sheet comprising the plurality of domes 112 and the connecting portion 114. For example, the first layer 102 (or sheet) may comprise a continuous sheet of material in which the plurality of domes 112 are formed. Thus, in some instances, the first layer 102 may be referred to as a monolithic component formed as a single piece (e.g., molded as a single piece).

[0055] In some instances, the spacing between adjacent vaults 112 can vary. In some instances, this spacing between adjacent vaults 112 can range from 0.5 mm to 3 mm (or from 10 mm to 30 mm measured from the center of one vault to the center of the adjacent vault). In some instances, this spacing between adjacent vaults 112 can be approximately 2 mm (or 22 mm measured from the center of one vault to the center of the adjacent vault).

[0056] In some instances, the spacing between adjacent vaults may be larger or smaller, depending on the material of the first layer 102 and / or the required density of the vaults on all or part of the first layer 102, depending on the degree of positional perception or tactile feedback required by the wearer.

[0057] In some instances, the multiple vaults 112 may extend across (or cover) the entire length and width of the inner bottom 100.

[0058] In some instances, the plurality of vaults 112 may extend across (or cover) at least a portion of the length and width of the insole 100. For example, in some cases, the vaults 112 may be arranged only in the forefoot area 120, midfoot area 122, heel area 124, or some combination thereof of the insole 100.

[0059] Each vault 112 can be in the first state (e.g.) Figures 1 to 3A as well as Figure 4 (as shown) and the second state (as shown) Figure 3B The vault 112 deflects between (as shown). This first state can be referred to as the undeflected state, and the second state can be referred to as the deflected state. In this first state, at least the peak of the vault 112 deflects along the first direction 126 (as shown). Figure 3A (As depicted) protrudes (or extends) outward or away from the connecting portion 114. In this second state, at least the peak of the vault 112 protrudes (or extends) along the second direction 128 (as shown). Figure 3B (As depicted) protrudes (or extends) outward or away from the connecting portion 114. The first direction 126 and the second direction 128 can be positive vertical and negative vertical directions, respectively, and they are perpendicular to the longitudinal direction 130, such as... Figure 3A and Figure 3B The coordinate axes depicted in the diagram.

[0060] When the insole 100 is placed in footwear products (such as...) Figure 11 When the footwear product 400 is inside the footwear product shown, the first direction 126 is toward the interior of the footwear product (e.g., toward the wearer's foot when the footwear product is worn by an individual), and the second direction 128 is toward the rest of the sole structure of the footwear product (such as the outsole).

[0061] In some instances, in this second state, at least the peak of the vault 112 is set flush with the connecting portion 114.

[0062] In some instances, in this second state, at least the peak of the vault 112 extends beyond the connecting portion 114 into the adjacent layer of the inner bottom, as further described below.

[0063] Each vault 112 responds to a force 132 applied to the vault 112 (by... Figure 3B (The arrow in the diagram schematically depicts) the vault 112, which can deflect from the first state to the second state. After deflection, the vault 112 rapidly springs back from the second state to the first state in response to the removal of force 132. After the removal of force 132 (when the vault 112 is unloaded), the vault 112's rebound or "rapid return" from the second state to the first state can transmit the first tactile sensation (or feedback) to the wearer's foot.

[0064] In some instances, the wearer can experience a second tactile sensation (e.g., a tactile snap-on sensation) by pressing the arch 112 (or multiple arches) from a first state to a second state (which presses the arch 112 into the rest of the insole 100 and away from the wearer's foot).

[0065] Thus, in some instances, the wearer can experience two tactile sensations: one when each dome 112 is pressed (entering the second state), and another when each dome springs back to the first state after the force 132 is removed.

[0066] In some instances, the force 132 can be a force (e.g., the wearer's body weight) applied to the insole 100 when the wearer walks, runs, or otherwise moves around while wearing footwear including the insole 100. Therefore, multiple arches 112 can be pressed simultaneously and to varying degrees as the wearer moves around. For example, different magnitudes of force can be applied to different arches 112 in the first layer 102 based on how the wearer moves and / or how they distribute their weight on the insole 100 during different activities. Thus, when the wearer wears the footwear, the arches 112 can provide feedback to the wearer about how they move, how they distribute their weight, etc.

[0067] Return to Figures 1 to 4The first layer 102 may include an inward-facing side 116 (facing the interior of the footwear, as defined above) and an opposite outward-facing side 118 (facing the outsole of the footwear, as defined above). In a first state of each vault 112, the vault 112 is convex relative to the inward-facing side 116 and concave relative to the outward-facing side 118. In a second state of each vault 112, the vault 112 is concave relative to the inward-facing side 116 and convex relative to the outward-facing side 118. In some instances, as used herein, the inward-facing or outward-facing side of different layers may also be referred to as the first / second surface or the inward / outward-facing surface of these layers.

[0068] Each vault 112 may have a diameter (or width) in the range of 10 mm to 30 mm, 15 mm to 25 mm, or 18 mm to 22 mm. In some instances, each vault 112 may have a diameter (or width) of approximately 20 mm.

[0069] Each vault 112 may have a height ranging from 0.5 mm to 2.0 mm, 1.3 mm to 1.7 mm, or 1.4 mm to 1.6 mm (when in the first state or the raised position). In some instances, each vault 112 may have a height of approximately 1.5 mm (when in the first state or the raised position). In some instances, the height of the vault 112 may vary based on the thickness of the first layer 102 and / or the diameter of the vault 112.

[0070] like Figure 3A As depicted, the height 134 of the vault 112 (in the first state) can be measured from the connecting portion 114 (on the inward-facing side 116 of the first layer 102) to the peak 136 (or apex) of the vault 112. Therefore, when the vault 112 is pressed from the first state to the second state, the amount by which the vault 112 can be pressed is at least the height 134 of the vault 112. In some instances, when the vault 112 is pressed from the first state to the second state, the amount by which the vault 112 can be pressed is greater than the height 134 of the vault 112 due to the openings in the underlying second layer 104, as further described below.

[0071] In some instances, if the vault 112 is partially pressed (not pressed into or not fully pressed into the corresponding opening in the second layer 104), the wearer's sensation may be diminished compared to when the vault 112 is fully pressed into the opening.

[0072] In some instances, the height and / or diameter of these vaults 112 may vary on the first layer 102. For example, in some cases, at least one vault 112 may have a different height and / or diameter than another vault 112 in the first layer 102.

[0073] In some instances, all the vaults 112 of the first layer 102 may have the same height, the same diameter, or the same height and the same diameter.

[0074] In some instances, each vault 112 may have a height-to-diameter ratio (HRR) in the range of 0.06 to 0.09, or approximately 0.075. In some instances, the HRR of the vault 112 may vary based on the thickness of the material of the first layer 102.

[0075] The first layer 102 (or sheet) may include a polymer material. In some instances, the polymer material is polycarbonate. In some instances, the polymer material may have stiffness or elasticity configured such that each vault 112 can deflect from a first state to a second state in response to a force applied to the vault 112, and each vault 112 rapidly springs back from the second state to the first state in response to the removal of the force.

[0076] In some instances, the material of the first layer 102 (such as the polymer material) may be configured to have relatively high thermoformability (or the ability to be manufactured in other ways), high fatigue strength to improve durability, low creep to improve tactile experience persistence throughout the product's lifespan, high stiffness to improve tactile feel, high impact strength to maintain shape, and / or similar properties. The material may be additionally or alternatively configured to address various environmental factors such as moisture, bonding, and temperature.

[0077] The thickness of the first layer 102 (or sheet) is 138 (in Figure 3A The first layer 102 (as depicted) can be configured such that each vault 112 can deflect from a first state to a second state in response to a force applied to the vault 112 (e.g., the wearer's body weight), and each vault 112 can rapidly spring back from the second state to the first state in response to the removal of that force. In some instances, the thickness 138 of the first layer 102 can be in the range of 0.26 mm to 0.51 mm (0.01 inch to 0.02 inch) or 0.35 mm to 0.41 mm (0.014 inch to 0.016 inch). In some instances, the thickness 138 of the first layer 102 can be about 0.38 mm (0.015 inch).

[0078] In some instances, the first layer 102 is formed by vacuum forming of the polymer material.

[0079] The insole 100 may include a second layer 104. For example... Figures 1 to 4 As shown, the second layer 104 is configured to be adjacent to the first layer 102 within the inner bottom 100. The second layer 104 is disposed against the outward-facing side 118 of the first layer 102 (specifically, the connecting portion 114 of the first layer 102). For example, the inward-facing side 154 (or surface) of the second layer 104 may be disposed against the outward-facing side 118 of the connecting portion 114 of the first layer 102 (face-to-face contact with the outward-facing side 118 of the connecting portion 114 of the first layer 102) (e.g. Figures 1 to 3B (As shown).

[0080] The second layer 104 includes a plurality of apertures 140 spaced apart from each other (e.g., ... Figure 4 (As shown). For example, the second layer 104 may be a sheet of material with spaced-apart openings 140 extending through the thickness of the second layer 104.

[0081] Each opening 140 of the second layer 104 is aligned with the corresponding vault 112 of the first layer 102. For example, as Figure 3A and Figure 3B As shown, when the first layer 102 and the second layer 104 are arranged abutting each other in the inner bottom 100, each opening 140 is directly set below the corresponding vault 112 (so that the opening and the vault are aligned in the longitudinal direction 130 and in the transverse direction perpendicular to the longitudinal direction 130 and the vertical directions 126, 128).

[0082] For each vault 112, in a first state (undeflected state), the vault 112 protrudes outward and away from the corresponding (or corresponding) opening 140, and in a second state (deflected state), the vault 112 extends into the corresponding opening 140. When the vault 112 extends into the corresponding opening 140, the vault 112 extends beyond the connecting portion 114 (e.g., past the center), thereby forming a recessed shape relative to the inward-facing side 116 of the first layer 102.

[0083] In some instances, the second layer 104 may comprise a polymer. In some instances, the second layer 104 comprises ethylene glycol-modified polyethylene terephthalate (PETG).

[0084] In some instances, the second layer 104 comprises rubber. Such a material can provide increased manufacturability and / or sound attenuation when the vault 112 is pressed into and rapidly ejected from the second layer 104.

[0085] The second layer 104 has a thickness that can range from 0.38 mm to 1.5 mm (0.015 inches to 0.06 inches). In some instances, the second layer 104 has a thickness that can be about 0.51 mm (0.02 inches). This thickness of the second layer 104 can define the depth 142 of each opening 140, each opening 140 being configured to receive a corresponding vault 112 therein. Accordingly, as the thickness of the second layer 104 increases, a greater perceptible sensory or tactile response can be delivered to the wearer during the pressing of the vault 112 into the opening 140 and during the release of the vault 112 from the opening 140.

[0086] In some instances, the depth 142 of these orifices 140 is greater than the thickness 138 of the first layer 102.

[0087] In some instances, the depth 142 of these apertures 140 is the same as or less than the thickness 138 of the first layer 102.

[0088] In some instances, the second layer 104 is formed by laser cutting.

[0089] In some instances, the second layer 104 can be formed by die-cutting.

[0090] The insole 100 may include a third layer 106. In some instances, the third layer 106 may be the innermost layer of the insole 100. Figures 1 to 4 The third layer 106 is disposed against the inward-facing side 116 of the first layer 102. Specifically, the outward-facing side 150 (or surface) of the third layer 106 is disposed against the inward-facing side 116 of the first layer 102 (face-to-face contact with the inward-facing side 116 of the first layer 102).

[0091] The third layer 106 includes a plurality of spaced-apart vaults 144 that conform to the contours of the plurality of vaults 112 of the first layer 102. For example, when assembling the inner bottom 100 (as... Figures 1 to 3B As shown), each vault 144 of the third layer 106 can cover the corresponding vault 112 of the first layer 102 or be set directly on top of the corresponding vault 112 of the first layer 102.

[0092] The third layer 106 can be formed from a single sheet of material. Accordingly, the plurality of vaults 144 can be formed in the material of the third layer 106 and spaced apart by the connecting portion 146 of the third layer 106. Each vault 144 protrudes outward and away from the connecting portion 146 in its un-deflected state (the first state of the vault 112). In other words, these vaults 144 can be raised relative to the connecting portion 146 on the inward-facing side 148 (or surface) of the third layer 106.

[0093] In some instances, the vault 144 of the third layer 106 may be formed by a recess in the outward-facing side 150 (such that the outward-facing side 150 conforms to the contour of the vault 112), and the inward-facing side 148 of the third layer 106 may be flat (rather than contoured). Thus, the inward-facing side 148 or surface of the third layer 106 may have the appearance of a standard insole.

[0094] In some instances, the third layer 106 comprises foam. Accordingly, the third layer 106 can be compressible and provide cushioning (and / or comfort).

[0095] In some instances, the third layer 106 includes foam covered by a top fabric (or textile) forming the inward-facing side 148.

[0096] In some instances, the foam is EVA, PU, ​​silicone, and / or other types or combinations of foam.

[0097] In some instances, the foam can have a hardness of approximately 20C. In other instances, the foam can be softer and have a hardness in the range of 10C to 20C.

[0098] In some instances, the topcoat (or textile) includes synthetic textiles such as polyester or nylon.

[0099] like Figure 3A and Figure 3B As shown, when a force 132 (e.g., the wearer's body weight) is applied to a portion of the insole 100, the vault 144 can be compressed and pressed into the corresponding vault 112, thereby pressing the corresponding vault 112 against the second layer 104. During the transition from the second state to the first state, the vault 144 can conform to the contour of the corresponding vault 112 and abut against the corresponding vault 112.

[0100] In some instances, the third layer 106 may have a thickness ranging from 1 mm to 4 mm, or from 2.5 mm to 3.5 mm.

[0101] In some instances, if the third layer 106 consists only of textiles (instead of foam), the third layer 106 may have a thickness of 0.5 mm to 1.5 mm.

[0102] The insole 100 may include a fourth layer 108. The fourth layer 108 may be disposed against the outward-facing side 152 (or surface) of the second layer 104. For example, when assembling the insole 100 (such as...) Figures 1 to 3BAs shown), the inward-facing side 156 (or surface) of the fourth layer 108 can be positioned against the outward-facing side 152 of the second layer 104 (face-to-face contact with the outward-facing side 152 of the second layer 104).

[0103] When the vault 112 of the first layer 102 is in the second state ( Figure 3B When the vault 112 is in the deflected or pressed state shown, at least the peak of the vault 112 extends into the corresponding opening 140 of the second layer 104 on the inward-facing side 156 facing the fourth layer 108.

[0104] In some instances, in the second state, the vault 112 can contact the inward-facing side 156 of the fourth layer 108. Thus, the fourth layer 108 can serve as a stop (or backing) for the vault 112.

[0105] In some instances, the fourth layer 108 is relatively flat or planar.

[0106] The fourth layer 108 may include a polymer. In some instances, the fourth layer 108 includes PETG.

[0107] In some instances, the fourth layer 108 comprises rubber. As the vaults 112 move between their first and second states, the rubber-made fourth layer 108 can provide enhanced sound attenuation.

[0108] The fourth layer 108 has a thickness that can range from 0.38 mm to 1.5 mm (0.015 inches to 0.06 inches). In some instances, the fourth layer 108 has a thickness that can be approximately 0.51 mm (0.02 inches).

[0109] In some instances, when the fourth layer 108 comprises rubber, it may have a thickness of about 1.5 mm or in the range of 1 mm to 1.8 mm.

[0110] In some instances, the fourth layer 108 is formed by laser cutting.

[0111] In some instances, the fourth layer 108 is formed by die-cutting.

[0112] The insole 100 may include a fifth layer 110. This fifth layer 110 may form the outermost layer of the insole 100 (on the outward-facing side). For example, the fifth layer 110 may be configured to provide support to the upper (e.g., Figure 11 The grip strength of the 404 upper (as shown below) of the Strobel.

[0113] In some instances, the fifth layer 110 may be positioned against the outward-facing side 158 of the fourth layer 108. For example, the inward-facing side 160 of the fifth layer 110 may be positioned against the outward-facing side 158 of the fourth layer 108 (face-to-face contact with the outward-facing side 158 of the fourth layer 108).

[0114] In some instances, if the fourth layer 108 is omitted from the inner bottom 100, the fifth layer 110 may be positioned against the outward-facing side 152 of the second layer 104.

[0115] The fifth layer 110 is a textile. In some instances, the textile is a knitted, woven, or nonwoven textile. In some instances, the nonwoven textile is felt. Thus, the fifth layer 110 may include a material that provides grip between the insole 100 and the stroopare of the upper of the footwear (as shown in the reference below when the insole 100 is disposed within the upper). Figure 11 (as described above). For example, the outward-facing side 164 of the fifth layer 110 can be configured to abut against and grip the strobel setting of the upper of the footwear.

[0116] The fifth layer 110 has a thickness of 162. In some instances, the thickness 162 is in the range of 1.5 mm to 2.5 mm, 1.8 mm to 2.2 mm, 1.95 mm to 2.05 mm, or about 2 mm.

[0117] In some instances, the fifth layer 110 is relatively flat or planar.

[0118] The edges of one or more layers of the insole 100 form the periphery of the insole 100, i.e., the periphery boundary. In some instances, at least the edge of the first layer 102 forms this periphery boundary of the insole 100. In some instances, the edges of the first layer 102 and the second layer 104 form this periphery boundary of the insole 100.

[0119] In some instances, one or more of layers 104, 106, 108, and / or 110 may be omitted from the insole 100. For example, in some instances, the insole 100 may not include the fourth layer 108. In some instances, the insole 100 may not include the third layer 106.

[0120] In some instances, the insole 100 (or insole) can be formed by forming a roll or assembly of all the stacked layers of the insole 100, and then die-cutting the assembly into the desired overall shape of the insole 100. In this way, different sizes of the insole 100 (or insole) can be formed from the same roll of stacked assembly layers.

[0121] In some instances, the insole 100 (or insole 200, as described below) may include additional layers (such as... Figure 12 and Figure 13 The exemplary sixth layer 170 depicted is configured to attenuate (or reduce) sound when the vaults 112 deflect from their first state to their second state and / or when they return (or bounce back) to their first state.

[0122] like Figure 13 As shown, the sixth layer 170 is configured to connect to the first layer 102. Therefore, in some instances, the sixth layer 170 may be disposed between the first layer 102 and the second layer 104 within the insole 100 (or a similar insole, such as insole 200). In such cases, in Figure 4 In this arrangement, the sixth layer 170 will be positioned between the first layer 102 and the second layer 104.

[0123] like Figure 12 As shown, the sixth layer 170 may include a sheet of material cut to form a plurality of protrusions 172 extending from the connecting portion 174 of the sheet. Each protrusion 172 includes a rod portion 176 and a free end 178 disposed at the distal end of the rod portion 176. The free end 178 may be wider than the rod portion 176, such as... Figure 12 and Figure 13 As shown.

[0124] In some instances, the free end 178 of the protrusion 172 is rounded.

[0125] Each protrusion 172 is surrounded by (and formed by) a cut 180. In some instances, such as Figure 12 and Figure 13 As shown, each cut 180 is C-shaped, thereby defining the rod portion 176 and the circular free end 178 corresponding to the protrusion 172.

[0126] When the sixth layer 170 is disposed in the insole (such as the insole 100) between the first layer 102 and the second layer 104, the connecting portion 174 of the sixth layer 170 can be sandwiched between the first layer 102 and the second layer 104 and contact each of the first layer 102 and the second layer 104.

[0127] The sixth layer 170 may include a flexible material configured to reduce or attenuate sound. In some instances, the sixth layer 170 includes synthetic leather. In some instances, the sixth layer 170 includes rubber.

[0128] The shape and size of each cut 180 can be set to surround the corresponding vault 112 in the first layer 102. Therefore, the free end 178 of the protrusion 172 formed by the cut 180 can be positioned on and attached to the apex or peak 136 of the corresponding vault 112, as shown below. Figure 13 As shown.

[0129] The sixth layer 170 is attached (e.g., bonded by adhesive or other attachment methods) to the outward-facing side 118 of the first layer 102, as shown. Figure 13 As shown. In some instances, such as Figure 13 As shown, each free end 178 of the protrusion 172 is attached to the center (or peak 136) of the corresponding vault 112. As described above, in an example where the inner bottom 100 includes a sixth layer 170, the sixth layer 170 may be attached to the outward-facing side 118 of the first layer 102 and arranged adjacent to the inward-facing side 154 of the second layer 104 (see [link to documentation]). Figure 3A and Figure 4 (Refer to each side of these layers).

[0130] By attaching the free end 178 of the protrusion 172 to the arch 112, each arch 112 gains mass, thereby helping to suppress partial resonance of the arch during arch deformation (between the first and second states, as described herein). Therefore, any clicking sounds that the arch 112 might produce when the user applies and removes their weight from the insole can be reduced, thus providing a better experience for the user (wearer) when wearing footwear including the insole.

[0131] Figure 5 An exemplary insole 200 is shown, which is similar to insole 100, except that the exemplary insole 200 has a different arrangement of the vault 244 of the third layer 206 and the vault 244 of the first layer 202 (which may otherwise be the same as or similar to the first layer 102 of insole 100). It should be noted that although the vault 244 of the first layer 202 is in... Figure 5 While not visible in the view, each vault of the first layer 202 can be directly positioned below the corresponding vault 244 of the third layer 206. Additionally, each layer or component of the inner bottom 200 corresponding to a layer or component of the inner bottom 100 can be similarly numbered. For example, layer 206 can correspond to layer 106, and layer 202 can correspond to layer 102.

[0132] In the inner bottom 200, the vaults 244 of the third layer 206 (and the vaults of the first layer 202) can be sized and arranged on the inner bottom 200 such that there are no partial vaults (e.g., half-vaults or quarter-vaults). Therefore, the vaults 244 (and their corresponding vaults of the first layer 202) can have varying diameters, such that all these vaults fit within the boundaries of the inner bottom 200. For example, as... Figure 5 As shown, some vaults 244 located near the periphery of the inner bottom 200 may have a smaller diameter than vaults 244 located closer to the central longitudinal axis of the inner bottom 200.

[0133] The second layer of the inner bottom 200 (which may be similar to the second layer 104 of the inner bottom 100) may have orifices of corresponding size (e.g., the diameter of these orifices may match the diameter of the vault 244 and the vault of the lower first layer 202).

[0134] The remaining layers of the insole 200 may be the same as or similar to the insole 100. For example, the insole 200 may include a fourth layer 208 and a fifth layer 210 (which are the same as or similar to the fourth layer 108 and the fifth layer 110 of the insole 100).

[0135] Figures 6 to 10 It shows products for footwear (such as) Figure 11 The exemplary insole 300 of the footwear article 400 shown (as further described below) includes components that provide tactile sensation to the wearer's foot (sole). The insole 300 may include one or more layers. In some instances, such as... Figures 6 to 9 As shown, the inner bottom 300 comprises multiple stacked layers. Figure 6 A perspective view of the assembled insole 300 is shown. Figure 7 A cross-sectional side view of the assembled insole 300 is shown. Figure 8 It shows Figure 7 A detailed view of a portion of the cross-sectional view 301, and Figure 9 An exploded view of the insole 300 is shown. Figure 10 The outward-facing surface 330 (or side) of the third layer 308 of the insole 300 is shown.

[0136] The insole 300 includes one or more spring-loaded arches 302 (referred to herein as "arches") configured to deflect in response to an applied force (e.g., the wearer's body weight) and return to their undeformed state when unloaded (when the force is removed). Arches 302 may be referred to as "monostable" because they have a stable or stationary first state (which may be referred to as the undeformed state) and move to a second state (which may be referred to as the deformed state) in response to an input (the applied force).

[0137] In some instances, the inner bottom 300 may include a single vault 302.

[0138] In some instances, such as Figures 7 to 10 As shown, the inner bottom 300 includes multiple vaults 302.

[0139] like Figure 9 As shown in the exploded view, these vaults 302 are separate vaults 302 that are not connected to each other.

[0140] In some instances, these vaults 302 comprise metals such as spring steel.

[0141] In some instances, these vaults 302 comprise polymers.

[0142] In some instances, these vaults 302 include composite materials (e.g., carbon fiber).

[0143] These vaults 302 are not fixed to other components of the inner bottom 300. For example, each vault 302 is not fixed around its edge.

[0144] Instead, each vault 302 is disposed within a unit 312 (or opening) of a first layer 304 of the inner bottom 300. In some instances, the first layer 304 includes at least one unit 312 configured to receive the at least one vault 302.

[0145] In some instances, such as Figures 6 to 10 As shown, the first layer 304 may include a plurality of units 312 spaced apart on the first layer 304 (the plurality of units 312 may also be referred to as an array of units 312). These units 312 may extend through the entire thickness 314 of the first layer 304. Accordingly, each unit 312 may be open at both ends.

[0146] In some instances, these units 312 may not extend through the entire thickness 314. Instead, these units 312 may extend through a portion of the thickness 314 of the first layer 304, such as extending from the inward-facing surface 316 of the first layer 304 toward the outward-facing surface 318 (but not all the way to the outward-facing surface 318). Accordingly, these units 312 may be open at one end (at the inward-facing surface 316) and closed at the other end (closed by the outward-facing surface 318 covering the unit 312).

[0147] In some instances, the thickness 314 of the first layer 304 can be in the range of 3 to 5 mm, 3.5 to 4.5 mm, or 3.9 to 4.1 mm. In some instances, the thickness 314 of the first layer 304 can be about 4 mm (e.g., 4 ± 0.05 mm).

[0148] In some instances, the shape of these elements 312 can match the shape of the vault 302. For example, as Figure 9 As shown, in some cases, each vault 302 may have four points or end edges 303 extending outward from the central portion of the vault 302. The central portion of the vault 302 is raised or protruded outward relative to the end edges 303, thereby forming its vault shape. The sidewall 320 of each unit 312 may be matched with the overall shape (e.g., width) of the corresponding vault 302, such that the vault 302 is fitted within the unit 312.

[0149] In some instances, each unit 312 may have a width 315 that is the same as the width of the vault 302 (measured from one end edge 303 to the opposite end edge 303).

[0150] In some instances, each unit 312 may have a width 315, which is greater than the width of the vault 302.

[0151] Each vault 302 is freely located within the corresponding unit 312 such that the vault 302 is not attached to the side wall 320 of the unit 312. For example, all end edges 303 of the vault 302 may not be attached to the side wall 320 of the unit 312.

[0152] In some instances, all end edges 303 of the vault 302 are spaced apart from the sidewalls 320 of the unit 312.

[0153] In some instances, the first layer of 304 stainless steel may include foam. In some instances, the foam is Ortholite. In this way, the first layer of 304 stainless steel may be compressible.

[0154] The insole 300 may include a second layer 306, which serves as a backing or base layer for the first layer 304.

[0155] In some cases, the inner bottom 300 may not include the second layer 306 when the cells 312 do not extend all the way through the first layer 304 (so that these cells 312 are not open at the outward-facing surface 318).

[0156] The second layer 306 may include a polymer. In some instances, the polymer is ethylene glycol-modified polyethylene terephthalate (PETG).

[0157] The second layer 306 has a thickness 322 defined between the inward-facing surface 324 and the outward-facing surface 326 of the second layer 306.

[0158] In some instances, the thickness 322 can be in the range of 0.25 mm to 1.0 mm, 0.25 mm to 0.51 mm, or 0.4 mm to 0.5 mm.

[0159] The inward-facing surface 324 of the second layer 306 may be disposed against the outward-facing surface 318 of the first layer 304 (e.g., face-to-face contact with the outward-facing surface 318 of the first layer 304). Accordingly, the end edge 303 of each vault 302 may be disposed against the inward-facing surface 324 of the second layer 306.

[0160] The insole 300 may include a third layer 308 configured to activate or interact with the vault 302. For example, the third layer 308 has an inward-facing surface 328 and an outward-facing surface 330. The outward-facing surface 330 includes at least one protrusion 332 configured to press against and abut against the apex 305 of the central portion of the corresponding vault 302 when a force is applied to the inward-facing surface 328 of the third layer 308.

[0161] In some instances, such as Figure 10 As shown, the third layer 308 includes a plurality of protrusions 332 spaced apart on the outward-facing surface 330 of the third layer. Each protrusion 332 can be configured to press against a corresponding dome 302 within a corresponding unit 312 of the first layer 304. For example, when the outward-facing surface 330 of the third layer is disposed against the inward-facing surface 316 of the first layer 304, each protrusion 332 extends at least partially into the corresponding unit 312, extending toward but spaced apart from the corresponding dome 302 (e.g., ...). Figure 8 (As shown).

[0162] The third layer 308 has a thickness 334 defined between the inward-facing surface 328 and the outward-facing surface 330. Each protrusion 332 has a height 336 (e.g., Figure 8 (As shown). In some instances, the height 336 can range from 0.75 mm to 2.0 mm, 0.8 mm to 1.5 mm, or 1 mm to 1.4 mm. The height 336 can vary based on the stiffness and thickness of the third layer 308, and / or the vault height.

[0163] In some instances, the third layer 308 comprises a polymer, such as thermoplastic polyurethane (TPU). In some instances, the third layer 308 comprises 3D-printed TPU.

[0164] The insole 300 may include a fourth layer 310. The fourth layer 310 has an inward-facing surface 338 and an outward-facing surface 340, wherein the outward-facing surface 340 is disposed against the inward-facing surface 328 of the third layer 308 (face-to-face contact with the inward-facing surface 328 of the third layer 308).

[0165] In some instances, the fourth layer 310 may include textiles (e.g., a top fabric) and form a top cover for the insole 300. The fourth layer 310 has a thickness 342, which may be in the range of 0.2 mm to 1.0 mm.

[0166] In some instances, one or more of layers 306 and / or 310 may be omitted from the inner bottom 300.

[0167] In footwear products (such as Figure 11 During use within the footwear article 400 shown, when compressive force (e.g., from the wearer's foot) causes compression of the first layer 304, each protrusion 332 of the third layer 308 moves toward and contacts the corresponding arch 302, causing the corresponding arch 302 to elastically deform within the corresponding unit 312. In some instances, this may include pressing the apex 305 (or peak) of the arch 302 against the inward-facing surface 324 toward the second layer 306. In this way, the protrusions 332 provide a point load on the surface of the central portion of the arch 302.

[0168] When the vault 302 is unloaded (e.g., when the wearer's body weight is reduced or removed), the vault 302 quickly springs back to its original shape. Figure 8 (As shown in the first state). The rapid rebound of the arch 302 can produce an upward pressing or perceptible sensation on the wearer's foot. The various arches 302 of the insole 300 "press upward" as the wearer shifts their center of gravity, thus providing tactile feedback to the wearer.

[0169] Figure 11 An exemplary footwear article 400 is shown, which is configured to include an insole 100 (or any of the other insoles described herein, such as insole 200, insole 300, or insole 500). Specifically, Figure 11 A side view of the footwear product 400 is shown, which may also be referred to simply as product 400.

[0170] The article 400 can be configured for use with various types of footwear, including but not limited to hiking boots, football boots, rugby boots, athletic shoes, running shoes, cross-training shoes, rugby boots, basketball shoes, baseball shoes, and other types of shoes. Furthermore, in some instances, the article 400 can be configured for use with various types of non-sports-related footwear, including but not limited to slippers, sandals, high heels, loafers, and any other types of footwear, apparel, and / or sports equipment (e.g., gloves, helmets, etc.).

[0171] The footwear article 400 includes two main components: a sole structure 402 and an upper 404. The upper 404 is coupled to the sole structure 402 to form a foot-receiving cavity between the sole structure 402 and the upper 404. For example, the upper 404 may include one or more material elements (e.g., textiles, foam, leather, and synthetic leather) that may be stitched, bonded by adhesives, molded, or otherwise formed to define an internal cavity configured to receive the foot. These material elements may be selected and arranged to selectively impart properties such as durability, breathability, abrasion resistance, flexibility, and comfort. The upper 404 may have various shapes, sizes, and / or designs. For example, in an example where the footwear article 400 is a running shoe, the upper 404 may be a low-top upper. In an example where the footwear article 400 is a basketball shoe, the upper 404 may be a high-top upper shaped to provide support at the ankle.

[0172] The sole structure 402 can be configured to provide adhesive friction for the footwear article 400. In addition to providing adhesive friction, the sole structure 402 can attenuate ground reaction forces when compressed between the foot and the ground during walking, running, or other walking activities. The configuration of the sole structure 402 can vary in different instances to include a variety of conventional or unconventional structures. When the footwear article 400 is worn, the sole structure 402 extends between the upper 404 and the ground. In different instances, the sole structure 402 may include different components. For example, the sole structure 402 may include an outsole, a midsole, and / or an insole. In some cases, one or more of these components may be optional.

[0173] exist Figure 11In the example shown, the sole structure 402 includes an outsole 406. In some examples, the outsole 406 is directly attached to the upper 404. In some examples, a midsole may be disposed between the upper 404 and the outsole 406 (e.g., where the midsole is configured to provide cushioning).

[0174] In some cases, the outsole 406 of the sole structure 402 can be configured according to one or more types of ground surfaces on which it can be used. For example, the shape, size, and / or number of lugs or protrusions of the outsole can be specified based on the type of ground surface on which it can be used. As another example, the material and / or material properties (e.g., density, surface finish, etc.) of the outsole can be specified based on the type of ground surface on which it can be used. Examples of ground surfaces include, but are not limited to, natural turf, synthetic turf, soil, natural grass, soft natural grass, and other surfaces.

[0175] The sole structure 402 also includes an insole 100. However, in some instances, the insole 100 may be replaced by any of the other insoles described herein within the article 400.

[0176] The insole 100 is disposed inside the upper 404. In some instances, the upper 404 includes a strobel, and the insole 100 is disposed inside the upper 404, abutting against the strobel. Thus, in some instances, when the article 400 is worn by a wearer, the upper surface or inward-facing surface of the insole 100 can come into direct contact with the wearer's foot.

[0177] Figures 14 to 18 It shows products for footwear (such as) Figure 11 The footwear product 400 shown herein (as described herein) has an insole 500. The insole 500 may include one or more layers. In some instances, such as... Figures 14 to 17 As shown, the inner bottom 500 comprises multiple stacked layers. Figure 14 A perspective view of the assembled insole 500 is shown. Figure 15 A cross-sectional side view of the assembled insole 500 is shown, and Figure 17 An exploded view of the insole 500 is shown. Figure 16A It shows Figure 15 A detailed view of a selected portion 501 of the cross-sectional side view.

[0178] The insole 500 may be similar to the insole 100, as described herein. For example, the insole 500 includes a first layer 502, which may be the same as or similar to the first layer 102 of the insole 100. However, a second layer 504 of the insole 500 may be configured to receive an arch of the first layer 502 therein (when in the second deflected state) and provide sound attenuation or reduction.

[0179] like Figures 14 to 17 As shown, the first layer 502 includes a plurality of vaults 512 spaced apart from each other on the first layer 502 (e.g., Figure 17 (As shown). The first layer 502 also includes a connecting portion 514 that extends between and around the plurality of vaults 512. The connecting portion 514 may be continuous. In some instances, the connecting portion 514 may be referred to as being formed by a plurality of connecting segments that are continuous on the first layer 502.

[0180] In this way, each vault 512 can be surrounded by the connecting portion 514 (e.g., completely surrounded around its perimeter) (unless the vault is a vault 512 formed at the edge of the first layer 502, in which case the inner side or edge of the vault is surrounded by the connecting portion 514).

[0181] The first layer 502 may also be referred to as a sheet comprising the plurality of domes 512 and the connecting portion 514. For example, the first layer 502 (or sheet) may comprise a continuous sheet of material in which the plurality of domes 512 are formed. Thus, in some instances, the first layer 502 may be referred to as a monolithic component formed as a single piece (e.g., molded as a single integral part).

[0182] In some instances, the spacing between adjacent vaults 512 can vary. In some instances, this spacing between adjacent vaults 512 can range from 0.5 mm to 3 mm (or from 10 mm to 30 mm measured from the center of one vault to the center of the adjacent vault). In some instances, this spacing between adjacent vaults 512 can be approximately 2 mm (or 22 mm measured from the center of one vault to the center of the adjacent vault).

[0183] In some instances, the spacing between adjacent vaults 512 may be larger or smaller, depending on the material of the first layer 502 and / or the desired density of the vaults on all or part of the first layer 502, depending on the degree of positional perception or tactile feedback required by the wearer. For example, in some cases, by increasing the spacing between the vaults, the wearer will experience enhanced sensation (e.g., at the target area) or perceive the sensation more clearly at the target location on their feet.

[0184] In some instances, the multiple vaults 512 may extend across (or cover) the entire length and width of the inner bottom 500.

[0185] In some instances, the plurality of vaults 512 may extend across (or cover) at least a portion of the length and width of the insole 500. For example, in some cases, the vaults 512 may be arranged only in the forefoot area 520, midfoot area 522, heel area 524, or some combination thereof of the insole 500.

[0186] In some instances, one or more arches 512 may be specifically positioned along the first layer 502 (e.g., within a designated area of ​​the insole 500) to target specific areas of the wearer's foot. For example, one or more arches 512 may be positioned in the midfoot area 522 to target the arch of the wearer's foot, and / or one or more arches 512 may be positioned in the forefoot area 520 to target the toes or ball of the foot. Thus, the targeted placement of the arches 512 within the first layer 502 can provide the wearer with a varied sensation.

[0187] Each vault 512 can be in the first state (e.g.) Figures 14 to 16A as well as Figure 17 (as shown) and the second state (as shown) Figure 16B The vault 512 deflects between (as shown). This first state can be referred to as the undeflected state, and the second state can be referred to as the deflected state. In this first state, at least the peak of the vault 512 deflects along the first direction 126 (as shown). Figure 16A (As depicted) protrudes (or extends) outward or away from the connecting portion 514. In this second state, at least the peak of the vault 512 protrudes (or extends) along the second direction 128 (as shown). Figure 16B (As depicted) protrudes (or extends) outward or away from the connecting portion 514. The first direction 126 and the second direction 128 can be positive vertical and negative vertical directions, respectively, and they are perpendicular to the longitudinal direction 130, such as... Figure 16A and Figure 16B The coordinate axes depicted in the diagram.

[0188] When the insole 500 is placed in footwear products (such as...) Figure 11 When the footwear product 400 is inside the footwear product shown, the first direction 126 is toward the interior of the footwear product (e.g., toward the wearer's foot when the footwear product is worn by an individual), and the second direction 128 is toward the rest of the sole structure of the footwear product (such as the outsole).

[0189] In some instances, in this second state, at least the peak of the vault 512 is set flush with the connecting portion 514.

[0190] In some instances, in this second state, at least the peak of the vault 512 extends beyond the connecting portion 514 into the adjacent layer of the inner bottom 500, as further described below.

[0191] Each vault 512 responds to the force 132 applied to the vault 512 (by... Figure 16B (The arrow in the diagram schematically depicts) the vault 512, which can deflect from the first state to the second state. After deflection, the vault 512 rapidly springs back from the second state to the first state in response to the removal of force 132. After the removal of force 132 (when the vault 512 is unloaded), the vault 512's rebound or "rapid return" from the second state to the first state can transmit the first tactile sensation (or feedback) to the wearer's foot.

[0192] In some instances, the wearer can experience a second tactile sensation (e.g., a tactile snap-on sensation) by pressing the arch 512 (or multiple arches) from a first state to a second state (which presses the arch 512 into the second layer 504 below the insole 500 and away from the wearer's foot).

[0193] Thus, in some instances, the wearer can experience two tactile sensations: one when each dome 512 is pressed (entering the second state), and another when each dome springs back to the first state after the force 132 is removed.

[0194] As described herein with respect to insole 100, the force 132 can be a force (e.g., the wearer's body weight) applied to insole 500 when the wearer walks, runs, or otherwise moves around while wearing footwear including insole 500. Therefore, multiple arches 512 can be pressed simultaneously and to varying degrees as the wearer moves around. For example, different magnitudes of force can be applied to different arches 512 in the first layer 502 based on how the wearer moves and / or how they distribute their weight on insole 500 during different activities. Thus, when the wearer wears the footwear, the arches 512 can provide feedback to them about how they move, how they distribute their weight, etc.

[0195] Return to Figures 14 to 17 The first layer 502 may include an inward-facing side 516 (facing the interior of the footwear, as defined above) and an opposite outward-facing side 518 (facing the outsole of the footwear, as defined above). In a first state of each vault 512, the vault 512 is convex relative to the inward-facing side 516 and concave relative to the outward-facing side 518. In a second state of each vault 512, the vault 512 is concave relative to the inward-facing side 516 and convex relative to the outward-facing side 518. In some instances, as used herein, the inward-facing or outward-facing side of different layers may also be referred to as the first / second surface or the inward / outward-facing surface of these layers.

[0196] Each vault 512 may have a diameter (or width) ranging from 10 mm to 30 mm, 15 mm to 25 mm, or 18 mm to 22 mm. In some instances, each vault 112 may have a diameter (or width) of approximately 20 mm.

[0197] Each vault 112 may have a height ranging from 0.5 mm to 2.0 mm, 1.3 mm to 1.7 mm, or 1.4 mm to 1.6 mm (when in the first state or the raised position). In some instances, each vault 112 may have a height of approximately 1.5 mm (when in the first state or the raised position). In some instances, the height of the vault 112 may vary based on the thickness of the first layer 102 and / or the diameter of the vault 112.

[0198] In some instances, the diameter and / or height of the vault 512 may vary based on the type of footwear and / or the degree of tactile feedback or sensation desired by the wearer. Thus, the height and diameter of each vault 512, as well as the spacing between vaults 512 (and / or the position of vaults 512 along the first layer 502), may vary and be specified based on the target tactile sensation for the wearer.

[0199] The above description and Figure 3A The same as depicted can be used to measure the height of the vault 512 (in the first state) from the connecting portion 514 (on the inward-facing side of the first layer 502) to the peak 536 (or apex) of the vault 512 (e.g., Figure 3A (Height 134 shown). Therefore, when the vault 512 is pressed from the first state to the second state, the amount by which the vault 512 can be pressed is at least the height of the vault 512. In some instances, when the vault 512 is pressed from the first state to the second state, the amount by which the vault 512 can be pressed is greater than the height of the vault 512 due to the cavity in the underlying second layer 504, as further described below.

[0200] In some instances, if the vault 512 is partially pressed (not pressed into or not fully pressed into the corresponding vault or cavity in the second layer 504), the wearer's sensation may be diminished compared to when the vault 512 is fully pressed into the corresponding vault or cavity.

[0201] In some instances, the height and / or diameter of these vaults 512 may vary on the first layer 502. For example, in some cases, at least one vault 512 may have a different height and / or diameter than another vault 512 in the first layer 502.

[0202] In some instances, all the vaults 512 of the first layer 502 may have the same height, the same diameter, or the same height and the same diameter.

[0203] In some instances, each vault 512 may have a height-to-diameter ratio (HRR) in the range of 0.06 to 0.09, or approximately 0.075. In some instances, the HRR of the vault 512 may vary based on the thickness of the material of the first layer 502.

[0204] The first layer 502 (or sheet) may include a polymer material. In some instances, the polymer material is polycarbonate. In some instances, the polymer material may have stiffness or elasticity configured such that each dome 512 can deflect from a first state to a second state in response to a force applied to the dome 512, and each dome 512 rapidly springs back from the second state to the first state in response to the removal of the force.

[0205] In some instances, the material of the first layer 502 (such as this polymer material) can be configured to have relatively high thermoformability (or the ability to be manufactured in other ways), high fatigue strength to improve durability, low creep to improve tactile experience persistence throughout the product's lifespan, high stiffness to improve tactile feel, high impact strength to maintain shape, and / or similar properties. The material can be additionally or alternatively configured to address various environmental factors such as moisture, bonding, and temperature.

[0206] The thickness of the first layer 502 (or sheet) is 538 (in... Figure 16A The first layer 502 (as depicted) can be configured such that each vault 512 can deflect from a first state to a second state in response to a force applied to the vault 512 (e.g., the wearer's body weight), and each vault 512 can rapidly spring back from the second state to the first state in response to the removal of that force. In some instances, the thickness 538 of the first layer 502 can be in the range of 0.26 mm to 0.51 mm (0.01 inch to 0.02 inch) or 0.35 mm to 0.41 mm (0.014 inch to 0.016 inch). In some instances, the thickness 538 of the first layer 502 can be about 0.38 mm (0.015 inch).

[0207] In some instances, the first layer 502 is formed by vacuum forming of the polymer material.

[0208] In some instances, the first layer 502 can be relatively planar.

[0209] In some instances, the first layer 502 may be non-planar and have a profile that at least partially conforms to the shape of the wearer's foot. For example, the arch area of ​​the first layer 502 may project outward in a first direction 126 relative to adjacent portions of the first layer 502, such that the arch area conforms to the shape of the wearer's arch. Thus, when in the first state, the peaks 536 of one or more arches 512 of the first layer 502 may be at different vertical heights relative to each other. In some instances, one or more of the additional layers of the insole 500 (such as the second layer 504 and / or the third layer 506) may conform to the same profile of the first layer 502. In some cases, other insoles described herein (such as insole 100) may also have one or more layers profiled in this manner.

[0210] The insole 500 may include a second layer 504. For example... Figures 14 to 17 As shown, the second layer 504 is disposed within the inner bottom 500, adjacent to the first layer 502. The second layer 504 is disposed against the outward-facing side 518 of the first layer 502. For example, the inward-facing side 554 (or surface) of the second layer 504 may be disposed against the outward-facing side 518 of the first layer 502 (face-to-face contact with the outward-facing side 518 of the first layer 502) (e.g. Figures 14 to 16B (As shown).

[0211] The second layer 504 includes multiple vaults 540 spaced apart from each other (such as...). Figure 17 and Figure 18 (as shown) and a connecting portion 542 extending between and around the plurality of vaults 540. The connecting portion 542 may be continuous. In some instances, the connecting portion 542 may be referred to as being formed by a plurality of connecting segments that are continuous on the second layer 504.

[0212] The second layer 504 also includes a plurality of apertures 544 (and thus may be referred to as through holes) extending through the thickness of the second layer. For example, the second layer 504 may be a sheet of material having spaced apertures 544 extending through the thickness of the second layer 504.

[0213] These openings 544 are spaced apart from each other around each vault 540. For example, as Figure 17 and Figure 18 As shown, each vault 540 is surrounded by three openings 544 spaced apart around its perimeter, thus forming three arms, bridging portions, or connecting portions 546. These connecting portions 546 connect the vault 540 to the connecting portion 542.

[0214] As further described below, each set of openings 544 spaced apart around the same vault 540 may at least partially define a corresponding cavity 552 formed below the vault 540 in the first state. In some instances, the cavity 552 may be referred to as an opening because these cavities 552 extend from the inward-facing side 554 of the second layer 504 to the outward-facing side 556 at the corresponding opening 544.

[0215] In some instances, each vault 540 may have more or fewer than three openings 544 and three connecting portions 546 surrounding its perimeter. For example, in some cases, each vault 540 may be surrounded by only two openings 544 and two connecting portions 546. In some cases, each vault 540 may be surrounded by three or more openings 544 and three or more connecting portions 546.

[0216] Each aperture 544 has a length 541 and a width 543. In some instances, the dimensions of the aperture 544 (including the length 541 and / or the width 543) can vary. For example, these apertures 544 can be larger than... Figure 17 and Figure 18 The connection portion 546 may be shorter or longer (thus reducing its width) or narrower or wider.

[0217] Each vault 540 of the second layer 504 is aligned with the corresponding vault 512 of the first layer 502. For example, as Figure 16A and Figure 16B As shown, when the first layer 502 and the second layer 504 are arranged abutting each other in the inner bottom 500, each arch 540 is directly set below the corresponding arch 512 (so that the opening and the arch are aligned along the longitudinal direction 130 and the transverse direction perpendicular to the longitudinal direction 130 and the vertical directions 126, 128).

[0218] In some instances, such as Figure 16A and Figure 16B As shown, the connecting portion 542 of the second layer 504 is aligned with and overlaps the connecting portion 514 of the first layer 502.

[0219] Similar to dome 512, each dome 540 has a corresponding first state (undeflected state), such as Figure 16A As shown, and the second state (deflection state), as Figure 16B As shown. Each vault 540 can be deflected from the first state to the second state under the applied force 132, as described herein with respect to vault 512.

[0220] The profile of each vault 540 can conform to the profile of the corresponding vault 512. For example, each vault 540 can have approximately the same height and diameter as the corresponding vault 512 it is aligned with. By matching or approximately matching the profile / shape of the vault 512, the vault 540 can make the movement of the vault 512 between the first and second states smoother and less restricted (compared to a flat vault 540 that does not match the profile of the vault 512).

[0221] However, in some instances, the vault 540 may not match the profile of the vault 512, and the vault 540 may have a smaller height and / or be flat compared to the height of the vault 512.

[0222] The connecting portion 542 has a thickness 548. In some instances, this thickness 548 can range from 0.76 mm to 2.03 mm (0.03 inches to 0.08 inches). In some instances, the connecting portion 542 has a thickness 548 that can be about 1.91 mm (0.075 inches). The thickness 548 of the connecting portion 542 can define a depth 550 of a space or cavity 552 configured to receive respective vaults 540 and 512 therein. This depth 550 can be measured from the base or bottom of the vault 540 to the base of the connecting portion 542 (and the second layer 504), as shown below. Figure 16A As depicted, as the thickness 548 of the connecting portion 542 increases, a greater perceptible sensory or tactile response can be transmitted to the wearer during the pressing of the vault 512 into the cavity 552 and the release of the vault 512 from the cavity 552.

[0223] Thus, the second layer 504 can be considered to include a plurality of cavities 542 located below the corresponding vault 540 in the first state, each cavity being defined by these openings 544.

[0224] In some instances, the thickness 549 of the vault 540 may be less than the thickness 548 of the connecting portion 542, such as... Figure 16A The description.

[0225] In some instances, the thickness 549 of the vault 540 in the second layer 504 may be greater than the thickness 538 of the vault 512 in the first layer 502. For example, this thickness 549 may range from 0.51 mm to 1.02 mm (0.02 inches to 0.04 inches) or from 0.71 mm to 0.81 mm (0.028 inches to 0.032 inches). In some instances, the thickness 549 may be approximately 0.76 mm (0.03 inches).

[0226] In the first state, such as Figure 16AAs shown, each corresponding dome 540 of the second layer 504 and the dome 512 of the first layer 502 protrude outwards and away from the connecting portion 542 and the corresponding cavity 552 in the second layer 504. Under the action of pressure or force 132, the corresponding dome 540 and dome 512 extend beyond (see below) Figure 16B The connecting portion 542 enters the corresponding cavity 552, thereby forming a concave shape on the inward-facing side 516 relative to the first layer 502.

[0227] In some instances, the second layer 504 may comprise a thermoplastic elastomer (such as thermoplastic polyurethane or TPU) or rubber. Such a material can provide increased manufacturability and / or sound attenuation when the vault 512 is pressed into and rapidly ejected from the second layer 204.

[0228] In some instances, the second layer of 504 is formed by injection molding.

[0229] In some instances, the second layer of 504 can be formed by die-cutting.

[0230] The second layer 504 has an outward-facing side 556 (or surface). In some instances, this outward-facing side 556 of the second layer may define an outward-facing side or bottom of the insole 500, which is configured to face the strobal and / or outsole of the footwear article in which the insole is positioned.

[0231] In some instances, the insole 500 may include one or more additional layers, such as foam layers (e.g., similar to the fourth layer 108 and / or fifth layer 110 of the insole 100), on the outward-facing side 556 of the second layer 504. The presence of one or more additional layers in the insole 500 may depend on the type of footwear article using the insole 500. For example, running shoes or other athletic shoes may include one or more additional layers to enhance cushioning. Conversely, footwear articles intended for rehabilitation or enhanced tactile feedback may not include such one or more additional layers within the insole 500.

[0232] The insole 500 may include a third layer 506. In some instances, the third layer 506 may be the innermost layer of the insole 500. Figures 14 to 17 The third layer 506 is disposed against the inward-facing side 516 of the first layer 502. Specifically, the outward-facing side 558 (or surface) of the third layer 506 is disposed against the inward-facing side 516 of the first layer 502 (face-to-face contact with the inward-facing side 516 of the first layer 502).

[0233] The third layer 506 includes a plurality of spaced-apart vaults 560 that conform to the contours of the plurality of vaults 512 of the first layer 502. For example, when assembling the insole 500 (as... Figures 14 to 17 As shown), each vault 560 of the third layer 506 can cover the corresponding vault 512 of the first layer 502 or be directly set on top of the corresponding vault 512 of the first layer 502.

[0234] The third layer 506 can be formed from a single sheet of material. Accordingly, the plurality of vaults 560 can be formed in the material of the third layer 506 and spaced apart by the connecting portion 562 of the third layer 506. Each vault 560 protrudes outward and away from the connecting portion 562 in its un-deflected state (the first state of the vault 512). In other words, these vaults 560 can be raised relative to the connecting portion 562 on the inward-facing side 564 (or surface) of the third layer 506.

[0235] In some instances, the vault 560 of the third layer 506 may be formed by a recess in the outward-facing side 558 (such that the outward-facing side 558 conforms to the contour of the vault 512), and the inward-facing side 564 of the third layer 506 may be flat (rather than contoured). Thus, the inward-facing side 564 or surface of the third layer 506 may have the appearance of a standard insole.

[0236] In some instances, the shape of the material in the third layer 506 is set to conform to the shape of the vault 512 in the first layer, thereby forming Figures 14 to 17 The vault shown is 560.

[0237] In some instances, the third layer 506 comprises textiles. In some instances, the textile is a mesh fabric.

[0238] In some instances, the tension of the textile in the third layer 506 can be varied to facilitate or resist the deflection of the vault 512 in the first layer 502. For example, when the textile in the third layer 506 is tighter, the third layer 506 can resist the deflection of the vault 512. In contrast, if the textile in the third layer 506 is looser, the third layer 506 may not resist the deflection of the vault 512, thus allowing the vault 512 to move more freely between the first and second states.

[0239] like Figure 16A and Figure 16BAs shown, when a force 132 (e.g., the wearer's body weight) is applied to a portion of the insole 500, the vault 560 can be pressed into the corresponding vault 512, thereby pressing the corresponding vault 512 into the corresponding vault 540 of the second layer 504. During the transition from the second state to the first state, the vault 560 can conform to the contour of the corresponding vault 512 and abut against the corresponding vault 512.

[0240] In some instances, the third layer 106 may have a thickness ranging from 0.5 mm to 1.5 mm.

[0241] In some instances, the insole 500 may include an additional layer (e.g., an additional layer of foam) on the inward-facing side 564 of the third layer 506. As described above, the presence of one or more additional layers in the insole 500 may depend on the type of footwear article using the insole 500. For example, running shoes or other athletic shoes may include one or more additional layers to enhance cushioning. Conversely, footwear articles intended for rehabilitation or enhanced tactile feedback may not include such one or more additional layers within the insole 500.

[0242] The edges of one or more layers of the insole 500 form the periphery of the insole 500, i.e., the periphery boundary. In some instances, at least the edge of the first layer 502 forms this periphery boundary of the insole 500. In some instances, the edges of the first layer 502 and the second layer 504 form this periphery boundary of the insole 500.

[0243] In some instances, the edges of the insole 500 may include edge treatments (such as seam tape) to enhance adhesion between the layers.

[0244] In some instances, one or more of layers 504 and / or 506 may be omitted from the inner bottom 500.

[0245] In some instances, the insole 500 (or insole) can be formed by forming a roll or assembly of all the stacked layers of the insole 100, and then die-cutting the assembly into the desired overall shape of the insole 500. In this way, different sizes of the insole 500 (or insole) can be formed from the same roll of stacked assembly layers.

[0246] In some instances, one or more layers of the insole 500 may be formed separately and then bonded together. For example, in some cases, the first layer 502, the second layer 504, and / or the third layer 506 may be bonded together with an adhesive such as pressure-sensitive adhesive (PSA).

[0247] In some instances, the first layer 502 and the second layer 504 can be molded as a single integral part.

[0248] In some instances, such as Figure 19 As shown, one or more of the vaults 512 of the first layer 502 may include an outwardly extending protrusion 570 (or ridge) at its apex 536. The protrusion 570 is configured to more precisely concentrate pressure (or tactile sensation) on the sole of the wearer's foot. This may enhance the tactile sensation experienced by the wearer. These protrusions 570 may be formed in the first layer 502 (i.e., formed as a single piece), individually attached to the vaults 512, or formed on top of or against the inward-facing side 516 of the first layer 502 within a separate layer.

[0249] In some instances, any of the insoles described herein can be adapted for footwear articles having a sole structure (such as any of the sole structures described in U.S. Patent Application No. 18 / 940,251, which is incorporated herein by reference) that includes a sole component and a sensing node assembly configured to provide tactile feedback to the wearer of the footwear article.

[0250] For example, Figure 20 It is used in footwear products (such as...) Figure 11 The exploded view shown is of a sole assembly 600 of a footwear article 400, which includes an insole 602 and a sole structure 620. The insole 602 can be coupled with... Figures 14 to 18 (or Figure 19 The insole 500 is similar to that of the other insole, except that the position and size of the arches in different layers are set to match the position and size of the openings 628 and / or sensing nodes 630 in the underlying sole structure 620. For example, the insole may include a first layer 602 (which may be connected to...). Figure 14 The first layer 502 corresponds to the second layer 606 (which can be associated with the first layer 502). Figure 14 The second layer 504 corresponds to the third layer 608 (which can be associated with the second layer 504) and the third layer 608. Figure 14 (Corresponding to the third layer 506).

[0251] In some instances, insole 602 may be replaced by any of the other insoles described herein (such as insole 100, insole 200, or insole 300). Furthermore, in some instances, insole 600 may include a size larger than... Figure 20 More or fewer layers, as described in this article.

[0252] The sole structure 620 includes a sole member 622 and a sensing node assembly 624. The sole member 622 is adapted to receive the sensing node assembly 624. In some instances, the sole member 622 may be a midsole. In some instances, the sole member 622 may be an outsole. The sensing node assembly 624 includes a plurality of individual sensing nodes 630 that provide a tactile response to changes in the ground surface and / or provide a tactile response when different portions of the sole structure 620 (when worn by an individual) engage with the ground surface.

[0253] The sole component 622 includes a plurality of spaced-apart openings 628 defined by the walls or sidewalls of the sole component 622. Each sensing node 630 is arranged within a corresponding opening 628 and configured to translate freely (e.g., move up and down) within the corresponding opening 628. Further details regarding the sole structure 620 and other sole structures including sensing node assemblies can be found in U.S. Patent Application No. 18 / 940,251.

[0254] The insole 602 can be adapted based on the shape and arrangement of the sole component 622 and the sensing node assembly 624 of the sole structure 620. For example, the arch 610 in the third layer 608, the arches in the lower first layer 604 (these arches may be similar to the arch 512 of the insole 500), and the arches in the lower second layer 606 (these arches may be similar to the arch 540 of the insole 500) can be shaped and positioned on the insole 500 to correspond (or match) to the positions of the corresponding openings 628 in the sole component 622 and / or the sensing nodes 630 in the sensing node assembly 624. More specifically, when the insole 602 mates with the inward-facing surface 626 of the sole member 622 (positioned against the inward-facing surface 626 of the sole member 622), each arch assembly of the insole 600 (including the corresponding arch 610 and the arches of the underlying first layer 604 and second layer 606) can be aligned with and cover the corresponding sensing node 630. The shape and / or size of these arch assemblies of the insole 600 can be set to match the corresponding orifice 628 and / or sensing node 630. In this way, the tactile sensation of the wearer can be enhanced through the combination of the sensing node 630 and the arches of the first layer 604 of the insole 600.

[0255] The insole 602, or any of the other insoles described herein, may be positioned against and / or coupled to the inward-facing surface 626 of the sole member 622, thereby forming the sole assembly 600. In some instances, each sensing node 630 has a first end 632 (e.g., Figure 20As shown), when the insole 602 is positioned against the inward-facing surface 626 of the sole component 622, the first end 632 is directly connected to the insole 600.

[0256] In some instances, the sole assembly 600 can be attached to the upper, such as... Figure 11 The upper 404. For example, in some cases, the sole assembly 600 may be used in place of the sole structure 402 and the insole 100 in the footwear article 400 (for example, the insole 602 may replace the insole 100, and the sole structure 620 may replace the sole structure 402).

[0257] Any of the techniques described herein can be applied to garment articles other than insoles, such as gloves, shoulder straps, trouser seats, etc. For example, a garment article may include layers 102, 104, 106, 108, and 110 (or some combination thereof) of an insole 100, but shaped as a target part of the garment article, rather than the shape of an insole.
