[0007] 1. Utility Model Field

[0008] This disclosure generally relates to a footwear article having a modular board system, and more specifically, to a footwear article having a board that can be removed and replaced with another board.

[0009] 2. Background Description

[0010] Many traditional shoes or other footwear items typically consist of an upper and a sole attached to the underside of the upper. Traditional shoes also include an internal space, or cavity, formed by the inner surfaces of the upper and sole, which accommodates the user's foot before the shoe is secured to the foot. The sole attaches to the underside or boundary of the upper and lies between the upper and the ground. Therefore, when a shoe is worn, the sole typically provides stability and cushioning for the user. In some cases, the sole may include multiple components, such as an outsole, midsole, and toeboard. The outsole provides adhesion friction to the bottom surface of the sole, the midsole attaches to the inner surface of the outsole, and provides cushioning or added stability to the sole. For example, the sole may include specific foam materials that can increase stability along one or more desired locations on the sole, or foam materials that can reduce stress or impact energy on the foot or leg when the user is running, walking, or engaging in other activities. The sole may also include additional components embedded in the sole, such as plates, to increase the overall rigidity of the sole and reduce energy loss during use.

[0011] The upper typically extends upwards from the sole and defines the cavity that fully or partially covers the foot. In most cases, the upper extends across the instep and toe areas, passing through the inner and outer sides of these areas. Many footwear items may also include a tongue that extends across the instep area to bridge the gap between the inner and outer edges of the upper, which defines the opening into the cavity. The tongue may also be positioned below the lacing system and between the inner and outer sides of the upper to allow adjustment of the shoe's tightness. The tongue can also be manipulated by the user to allow the foot to enter or exit the internal space or cavity. Furthermore, the lacing system can allow the user to adjust certain dimensions of the upper or sole, thus allowing the upper to accommodate various foot shapes and sizes.

[0012] Shoe soles can include a variety of materials, which can be chosen based on one or more intended uses of the shoe. Soles can also include sections containing different materials specific to certain areas of the upper. For example, increased stability may be needed in the forefoot or heel area of ​​the sole to provide a higher level of resistance or stiffness. In contrast, other parts of the shoe may be softer to provide a flexible, cushioned area that conforms to the wearer's foot. Furthermore, wearers with flat feet or other special conditions often have padding added to their shoes for more targeted support. This wide range of user preferences leads to a desire for shoes that can be customized to provide cushioning, support, and stiffness along different areas, directions, and zones of the shoe.

[0013] However, while many currently available shoes have different features related to the characteristics mentioned above, many shoes have one or more plates in their sole construction that cannot be removed. Therefore, once the plate wears out or its elasticity decreases, the user will need to purchase a completely new pair of shoes to improve the plate.

[0014] Therefore, footwear items with modular plate systems are needed. These and other drawbacks of the prior art are outlined in the following disclosure. Utility Model Content

[0044] The following discussion and accompanying figures disclose various embodiments or configurations of shoe and sole constructions. While embodiments of shoe or sole constructions are disclosed with reference to athletic footwear (such as running shoes, tennis shoes, basketball shoes, etc.), the concepts associated with embodiments of shoe or sole constructions can be applied to a wide range of footwear types and styles, including, for example, cross-training shoes, soccer cleats, golf shoes, hiking shoes, hiking boots, ski and snowboard boots, soccer cleats and spikes, walking shoes, and track spikes. The concepts of shoe or sole constructions can also be applied to footwear items considered non-athletic, including dress shoes, sandals, loafers, slippers, and high heels. In addition to footwear, the specific concepts described herein can also be applied to other types of clothing or other athletic equipment, including helmets, padding or protective pads, shin guards, and gloves. Furthermore, the specific concepts described herein can be incorporated into mats, backpack straps, golf clubs, or other consumer or industrial products. Therefore, the concepts described herein can be used in a wide variety of products.

[0045] As used herein, the term "approximately" refers to possible numerical variations, for example, due to typical measurement and manufacturing processes used for footwear or other articles that may include embodiments disclosed herein; due to unintentional errors in these processes; due to differences in the manufacture, origin, or purity of the ingredients used to prepare the composition or mixture or to carry out the method; and so on. Throughout this disclosure, the terms "approximately" and "approximately" refer to a range of values ​​within ±5% of the numerical value preceding the term. As stated herein, all ranges disclosed in this application include the outer boundary of the range.

[0046] This disclosure relates to footwear articles and / or specific components of footwear articles, such as uppers and / or soles or sole structures. Uppers may include knitted components, woven fabrics, and / or nonwoven fabrics. Knitted components can be made by yarn knitting, woven fabrics can be made by yarn weaving, and nonwoven fabrics can be made by creating an integral nonwoven web. Knitted textiles include textiles formed by warp knitting, weft knitting, cross knitting, circular knitting, and / or other suitable knitting operations. For example, knitted fabrics may have a plain knit structure, a mesh knit structure, and / or a rib knit structure. Woven fabrics include, but are not limited to, textiles formed by any of a variety of weaving methods, such as plain weave, twill weave, satin weave, dobby weave, jacquard weave, double-layer weave, and / or double-layer fabric. For example, nonwoven fabrics include textiles made by air-laid and / or spin-laid methods. Uppers may include various materials, such as first yarns, second yarns, and / or third yarns, which may have different properties or different visual characteristics.

[0047] Figure 1-3 An exemplary embodiment of footwear article 100 is depicted, the footwear article 100 being configured as a shoe including an upper 102 and a sole structure 104. The upper 102 is attached to the sole structure 104 and together defines an internal cavity 106 (see...). Figure 2 and Figure 3 The foot can be inserted into this internal cavity. For reference, footwear 100 defines a forefoot area 108, a midfoot area 110, and a heel area 112 (see...). Figure 2 and Figure 3 The forefoot region 108 generally corresponds to a portion of the footwear 100 that covers the foot, including the toes, the ball of the foot, and the joints connecting the metatarsals to the toes or phalanges. The midfoot region 110 is adjacent to and adjacent to the forefoot region 108, and generally corresponds to a portion of the footwear 100 that covers the arch and bridge of the foot. The heel region 112 is adjacent to and adjacent to the midfoot region 110, and generally corresponds to a portion of the footwear 100 that covers the rear of the foot, including the heel or calcaneus, ankle, and / or Achilles tendon. For illustrative purposes, Figure 1 A vertical axis V is shown, which is located at the center of the footwear 100 and is generally perpendicular to or orthogonal to the longitudinal axis L. The vertical axis V extends through the midfoot region 110 of the footwear 100 and further defines a vertical plane disposed between the forefoot region 108 and the heel region 112. The longitudinal axis L extends through the sole 104 of the footwear 100 and is located within the forefoot region 108, the midfoot region 110, and the heel region 112. The longitudinal axis L defines a longitudinal plane that is generally perpendicular to the vertical plane of the vertical axis V, and the longitudinal plane L may be configured to be tangent to or coplanar with a portion of the sole 104.

[0048] Although only a single shoe 100, i.e., a shoe worn on a user's left foot, is shown, it should be understood that the concepts disclosed herein apply to a pair of shoes (not shown) comprising a left and a right foot, the size and shape of which can accommodate a user's left and right feet, respectively. However, for ease of disclosure, various aspects of this disclosure will be described with reference to a single shoe, but the following disclosure with reference to footwear article 100 applies to both left and right shoes. However, in some embodiments, differences may exist between the left and right shoes beyond the left / right configuration. Furthermore, in some embodiments, the left shoe may include one or more additional elements not included in the right shoe, and vice versa.

[0049] Many conventional shoe uppers are formed from multiple elements, such as textiles, polymer foams, polymer sheets, leather, and synthetic leather, which are joined together by adhesives or stitching at seams. In some embodiments, the upper 102 of the footwear article 100 is formed from a knitted structure or knitted components. In various embodiments, the knitted components can incorporate various types of yarns that can provide different properties to the upper. For example, one area of ​​the upper 102 can be formed from a first type of yarn that imparts a first set of properties, while another area of ​​the upper 102 can be formed from a second type of yarn that imparts a second set of properties. Using this configuration, the properties of the upper 102 can be varied throughout the upper 102 by selecting specific yarns for different areas of the upper 102.

[0050] Regarding the materials constituting the upper 102, the specific properties that a particular type of yarn will impart to the knitted component may depend, at least in part, on the materials of the various filaments and fibers that form the yarn. For example, cotton can provide a soft effect, biodegradability, or natural aesthetics to the knitted material. Elastomers and stretched polyesters can both provide knitted components with the desired elasticity and resilience. Rayon can provide a high-gloss and moisture-wicking material, wool can provide a material with increased moisture wicking, nylon can be a durable and abrasion-resistant material, and polyester can provide a durable and hydrophobic material.

[0051] Other aspects of the knitted component can also be varied to affect its performance and provide desired properties. For example, the yarn forming the knitted component may include monofilament yarn or multifilament yarn, or the yarn may include filaments each formed from two or more different materials. Furthermore, the knitted component can be formed using specific knitting processes to impart specific properties to it. Therefore, the materials forming the yarn and other aspects of the yarn can be selected to impart various properties to specific areas of the upper 102.

[0052] In some embodiments, after the knitted structure has a force applied to it in the transverse direction, the elasticity of the knitted structure can be measured based on a comparison of the width or length of the knitted structure in a first unstretched state with the width and length of the knitted structure in a second stretched state. In further embodiments, the upper 102 may also include additional structural elements. For example, in some embodiments, a heel plate or cover (not shown) may be provided on the heel region 112 to provide additional support for the user's heel. In some cases, other elements, such as plastic materials, logos, trademarks, etc., may also be applied and fixed to the outer surface using adhesive or thermoforming processes. In some embodiments, properties associated with the upper 102, such as stitch type, yarn type, or characteristics associated with different stitch types or yarn types, such as elasticity, aesthetic appearance, thickness, breathability, water resistance, or abrasion resistance, may vary. In some embodiments, the upper 102 consists of various layers that are heat-pressed together to bond the individual layers of the upper 102. For example, the layers constituting the upper 102 may be heat-pressed together at a single temperature. The materials constituting the upper 102 may include an inner mesh layer, a thermoplastic polyurethane (TPU) film, and an outer mesh layer. In some embodiments, the TPU outer skin may be applied along the outer surface of the upper.

[0053] Refer again Figure 1 The sole structure 104 is attached to or secured to the upper 102 and extends between the user's foot and the ground when the user wears the footwear 100. The sole structure 104 may include one or more components, including an outsole, midsole, heel, upper, and / or insole. For example, in some embodiments, the sole structure may include an outsole, midsole, and insole, with the outsole providing structural integrity and traction for the user, the midsole providing cushioning, and the insole providing arch support. Furthermore, the insole may be strobel stitching attached to the upper via strobel stitching, a forefoot plate, a last, or a combination thereof, and the insole may be positioned between the upper 102 and the sole structure 104, or it may be provided as part of the upper 102.

[0054] Furthermore, the insole may be placed within the cavity 106 of the upper 102, which may come into direct contact with the user's foot when the footwear 100 is worn. Additionally, the upper 102 may include a lining (not shown) that may increase comfort, for example, by reducing friction between the user's foot and the upper 102, sole 104, insole, etc., and / or by providing moisture-wicking properties. The lining may cover the entire cavity 106 or only a portion thereof. In some embodiments, straps (not shown) may be arranged around an opening in the cavity 106 to secure the lining to the upper 102 and / or provide an aesthetic element to the footwear 100.

[0055] Reference Figure 2 and Figure 3 The footwear article 100 further defines an outer side 116 and an inner side 118. When a user wears the shoes, the outer side 116 corresponds to the outward-facing portion of the footwear article 100, while the inner side 118 corresponds to the inward-facing portion of the footwear article 100. Therefore, the footwear article 100 has opposing outer sides 116 and inner sides 118. The inner side 118 and the outer side 116 are adjacent to each other along a longitudinal center plane or axis 120 of the footwear article 100, which is perpendicular to... Figure 1 The longitudinal axis L is coplanar. As will be discussed further herein, the longitudinal central plane or axis 120 can divide the central midline between the inner side 118 and the outer side 116 of the footwear article 100. In other words, the longitudinal plane or axis 120 can extend between the rear proximal end 122 and the front distal end 124 of the footwear article 100, and can continuously define the middle of the midsole 126, the sole structure 104 and / or the upper 102 of the footwear article 100, i.e., the longitudinal plane or axis 120 is a straight axis that passes through the rear proximal end 122 of the heel region 112 and extends to the front distal end 124 of the forefoot region 108.

[0056] Unless otherwise stated, and refer to Figure 2 and Figure 3 Footwear article 100 may be defined by a forefoot region 108, a midfoot region 110, and a heel region 112. The forefoot region 108 generally corresponds to a portion of footwear article 100 that covers a portion of foot 128, including toes or phalanges 130, the ball of the foot 132, and one or more joints 134 connecting the metatarsals 136 of foot 128 to the toes or phalanges 130. The midfoot region 110 is adjacent to and abuts the forefoot region 108. The midfoot region 110 generally corresponds to a portion of footwear article 100 that covers the arch 128 and the bridge 128. The heel region 112 is adjacent to and abuts the midfoot region 110. The heel region 112 generally corresponds to a portion of footwear article 100 that covers the rear portion of foot 128, including the heel or calcaneus 138, the ankle (not shown), and / or the Achilles tendon (not shown).

[0057] Still referencing Figure 2 and Figure 3The forefoot region 108, midfoot region 110, heel region 112, medial side 118, and lateral side 116 are intended to define the boundaries or areas of the footwear article 100. For this purpose, the forefoot region 108, midfoot region 110, heel region 112, medial side 118, and lateral side 116 generally characterize portions of the footwear article 100. Certain aspects of this disclosure may relate to portions or elements that extend together with one or more of the forefoot region 108, midfoot region 110, heel region 112, medial side 118, and / or lateral side 116. Furthermore, the upper 102 and the sole structure 104 may both be characterized as having portions within the forefoot region 108, midfoot region 110, heel region 112, and / or along the medial side 118 and / or lateral side 116. Therefore, the upper 102 and the sole structure 104, and / or the various parts of the upper 102 and the sole structure 104 may include portions disposed within the forefoot region 108, the midfoot region 110, the heel region 112 and / or along the inner side 118 and / or the outer side 116.

[0058] Still refer to Figure 2 and Figure 3 The diagram details the forefoot region 108, midfoot region 110, heel region 112, medial side 118, and lateral side 116. The forefoot region 108 extends from the toe tip 140 to the widest portion 142 of the footwear article 100. The widest portion 142 is defined or measured along a first line 144 perpendicular to a longitudinal axis 120 extending from the distal end of the toe tip 140 to the distal end of the heel tip 146 opposite to the toe tip 140. The midfoot region 110 extends from the widest portion 142 of the footwear article 100 to the thinnest portion 148. The thinnest portion 148 of the footwear article 100 is defined as the thinnest portion of the footwear article 100 measured along a second line 150 perpendicular to the longitudinal axis 120. The heel region 112 extends from the thinnest portion 148 of the footwear article 100 to the heel tip 146.

[0059] It should be understood that, given the foregoing description, those skilled in the art will appreciate many modifications, and that its various components can be incorporated into many footwear articles. Therefore, aspects of footwear article 100 and its components can be described with reference to the general area or portion of footwear article 100, while understanding that the boundaries of the forefoot region 108, midfoot region 110, heel region 112, medial side 118, and / or lateral side 116 described herein may vary from footwear article to footwear article. However, aspects of footwear article 100 and its various components can also be described with reference to the exact area or portion of footwear article 100, and the scope of the appended claims may include limitations related to these boundaries of the forefoot region 108, midfoot region 110, heel region 112, medial side 118, and / or lateral side 116 described herein.

[0060] Still referencing Figure 2 and Figure 3 The inner side 118 begins at the distal toe tip 140 and curves outward along the inner side of the footwear 100 towards the midfoot area 110 along the forefoot region 108. The inner side 118 reaches the first line 144, at which point it curves inward toward the central longitudinal axis 120. The inner side 118 extends from the first line 144 (i.e., the widest portion 142) toward the second line 150 (i.e., the thinnest portion 148), at which point it enters the midfoot area 110, i.e., upon crossing the first line 144. Once it reaches the second line 150, the inner side 118 curves outward away from the longitudinal central axis 120, at which point it extends into the heel area 112, i.e., upon crossing the second line 150. The inner side 118 then curves outward toward the heel tip 146, then inward, terminating at the point where it intersects the longitudinal central axis 120.

[0061] The outer side 116 also begins at the distal toe tip 140 and curves outward along the outer side of the footwear 100 along the forefoot region 108 toward the midfoot region 110. The outer side 116 reaches the first line 144, at which point it curves inward toward the longitudinal central axis 120. From the first line 144 (i.e., the widest portion 142), the outer side 116 extends toward the second line 150 (i.e., the thinnest portion 148), at which point it enters the midfoot region 110, i.e., upon crossing the first line 144. Once it reaches the second line 150, the outer side 116 curves outward away from the longitudinal central axis 120, at which point it extends into the heel region 112, i.e., upon crossing the second line 150. The outer side 116 then curves outward toward the heel tip 146, then inward, and terminates at the point where it intersects the longitudinal central axis 120.

[0062] Still referencing Figure 2 and Figure 3The upper 102 extends along the outer side 116 and the inner side 118, and passes through the forefoot region 108, the midfoot region 110, and the heel region 112 to accommodate and surround the user's foot. When fully assembled, the upper 102 also includes an inner surface 162 and an outer surface 164. The inner surface 162 faces inward and generally defines an inner cavity 106, and the outer surface 164 faces outward and generally defines the periphery or boundary of the upper 102. The upper 102 also includes an opening 166, which is at least partially located in the heel region 112 of the footwear article 100, providing access to the inner cavity 106 through which the foot can be inserted and removed. In some embodiments, the upper 102 may also include an instep region 168, which extends from the opening 166 in the heel region 112 in a region corresponding to the instep and adjacent to the forefoot region 108. The instep region 168 may include a region similar to that of the tongue 170 provided in this embodiment. In some embodiments, the upper 102 does not include the tongue 170, that is, the upper 102 is tongueless.

[0063] Reference Figure 1 The sole structure 104 includes a midsole 172 and an outsole 174. In some cases, the outsole 174 may be defined as a portion of the sole 104 that at least partially contacts an outer surface, such as the ground, when the footwear article 100 is worn. The outsole 174 may define the bottom end or bottom surface 176 of the sole structure 104 across the heel region 112, the midfoot region 110, and the forefoot region 108. Furthermore, the outsole 174 may include a ground-engaging portion or ground-engaging surface of the sole structure 104 and may be opposite to its insole. Figure 1 As shown, the bottom surface 176 of the outsole 174 may include a tread pattern 178, which may include various shapes and configurations. The outsole 174 may be formed of one or more materials to impart durability, abrasion resistance, wear resistance, or grip to the sole structure 104. In some embodiments, the outsole 174 may be formed of any kind of elastomeric material, such as rubber, including thermosetting elastomers or thermoplastic elastomers, or thermoplastic materials, such as thermoplastic polyurethane (TPU). In some embodiments, the outsole 174 may be defined with a Shore A hardness of up to 95. Furthermore, the outsole 74 may be manufactured by processes involving injection molding, vulcanization, layer-by-layer printing, i.e., additive manufacturing systems or methods, etc.

[0064] Still referencing Figure 1The midsole 172 can be defined as at least a portion of the outsole 104 extending from the outsole 174 toward the upper 102, or extending between the outsole 174 and the upper 102 and connecting the outsole 174 to the upper 102. The midsole 172 can be constructed solely of a thermoplastic material, such as polyurethane (PU), for example and / or ethylene vinyl acetate (EVA), copolymers thereof, or similar materials. In other embodiments, the midsole 172 can be EVA solid sponge (“ESS”) material, EVA foam (e.g., PUMA® ProFoam Lite), etc. TM The midsole 172 can be a single polymer material or a mixture of materials, such as EVA copolymers, thermoplastic polyurethanes, polyether block copolymers, organic sheets, thermoplastic materials (e.g., thermoplastic polyurethanes, thermoplastic elastomers, thermoplastic polyolefins, etc.), or supercritical foams. The midsole 172 can be a single polymer material or a mixture of materials, such as EVA copolymers, thermoplastic polyurethanes, polyether block amide (PEBA) copolymers, and / or olefin block copolymers. An example of PEBA material is PEBAX®. In some embodiments, the midsole 172 is manufactured using processes involving injection molding, vulcanization, and layer-by-layer printing, i.e., additive manufacturing systems or methods, etc.

[0065] In embodiments where the midsole 172 is formed by a supercritical foaming process, the supercritical foam may comprise microporous or particulate foams, such as TPU, EVA, PEBAX®, or mixtures thereof, manufactured using a process performed in an autoclave, injection molding equipment, or any sufficiently heated / pressurized container capable of handling the mixing of supercritical fluids (e.g., CO2, N2, or mixtures thereof) with a preferably molten material (e.g., TPU, EVA, polyolefin elastomers, or mixtures thereof). In an exemplary process, a solution of supercritical fluid and molten material is pumped into a pressurized container, and then the pressure within the container is released, causing the molecules of the supercritical fluid to rapidly convert into gas, forming vesicles within the material and causing the material to expand into a foam. In further embodiments, the midsole 172 may be formed using alternative methods known in the art, including the use of an expansion press, injection molding machine, particulate expansion process, cold foaming process, compression molding technology, die cutting, or any combination thereof. For example, the midsole 172 may be formed using a process that includes an initial foaming step, in which a supercritical gas is used to foam the material, which is then compression molded or die-cut into a specific shape.

[0066] Back Figure 2The footwear article 100 also includes a fastening system 180, which includes laces 184 and a plurality of eyelets 188. In this embodiment, the laces 184 extend through the plurality of eyelets 188. In some embodiments, the fastening system 180 may include an elastic band. The fastening system 180 may allow a user to modify the size of the upper 102 as needed by the wearer, for example, to tighten or loosen portions of the upper 102 and / or the sole 104 around the foot. The fastening system 180 may also include a strap (not shown) extending along the center of the upper 102, the strap including one or more loops through which the laces 184 may be guided. In other embodiments, the fastening system 180 may be a hook-and-loop fastening system, such as Velcro®. For example, in some embodiments, the fastening system 180 may include one or more hook-and-loop fastening straps. In other embodiments, the fastening system 180 may be another laceless fastening system known in the art. In yet another embodiment, the fastening system 180 may include various manual fastening systems, rotary closure devices, or automatic fastening systems, such as those described in U.S. Patent Application No. 15 / 780,368, filed May 31, 2018, and U.S. Patent Application No. 16 / 392,470, filed April 23, 2019, the entire contents of which are incorporated herein by reference.

[0067] This disclosure provides a removable sheet that can be manufactured using an additive manufacturing process (e.g., layer-by-layer printing). The additive manufacturing process combines user metrics collected from various sources (e.g., pressure heatmap information, laser scanners, force plates, user preferences, etc.) with continuous fiber fabrication (CFF) technology to optimize the sheet according to a specific user's performance preferences, such as propulsion, stability, and comfort. Compared to traditional subtractive manufacturing processes (e.g., injection molding, milling, grinding, etc.), additive manufacturing minimizes manufacturing waste of the sheet. Furthermore, additive manufacturing reduces the number of manufacturing steps and iterations, avoiding the excessive labor typically required for customized, unique designs optimized for specific user preferences. In addition, CFF manufacturing technology enables efficient and economical manufacturing of the sheet while using expensive, high-performance materials such as carbon fiber, glass fiber, and Kevlar®. Because additive manufacturing involves adding material during iterations to build the sheet as designed, waste of material and time is minimized. This is particularly important when considering the costs associated with expensive materials such as carbon fiber and Kevlar®, and when considering the supply and / or transportation of such materials as needed. By reducing waste, users can procure materials in more accurate quantities and with greater predictability, while also saving on transportation costs and emissions and / or pollution associated with transporting expensive materials over long distances, such as globally. In some embodiments, the method of manufacturing the board may be similar to the method disclosed in U.S. Patent Application No. 17 / 578,752, filed January 19, 2022, the entire contents of which are incorporated herein by reference. In some embodiments, the board may be manufactured using conventional manufacturing methods, i.e., without additive manufacturing methods.

[0068] Additive manufacturing using CFF is preferably used for manufacturing plates according to this disclosure. The additive manufacturing process can be performed using a 3D printer, such as those manufactured by MarkForged®, which is capable of receiving a design model and generating printing instructions to 3D print the plate. The design model can be an electronic three-dimensional representation of a plate intended to be formed for footwear articles. In some embodiments, the design model can be a 3D CAD file, a 3D stereolithography file (.STL file), or any file format compatible with web-based or cloud-based design programs, such as the Eiger provided by MarkForged®. TM .

[0069] Alternatively or additionally, the design model can be generated by the controller in response to input data. For example, as discussed further below, physical characteristics collected and input into the software for designing and generating the design model may include the end-user's weight, gait, and / or end-user foot pressure maps measured during standing, walking, fast-moving (cut) movements, and / or running. Furthermore, various foot measurements can be recorded to determine the appropriate size of the plate, and other aspects of the footwear, as well as gait-related data, can be obtained to determine whether the foot orientation indicates toe impact or heel impact, etc. Foot measurements and data can be used to determine the optimal geometry and performance characteristics of the plate, as well as the optimal position of the plate within the shoe. Additionally, the collected measurements and data can be used to select the materials constituting the plate. Moreover, the additive manufacturing process described herein allows for the customization of the plate's stiffness for a specific wearer based on the collected measurements and data. For example, the user's tendon stiffness and calf muscle strength can be measured to determine the appropriate stiffness of the plate for the wearer. Furthermore, the plate stiffness can be adjusted based on the specific user's biomechanics and running mechanics, such as how the wearer's joint angles change during exercise, for example, through dorsiflexion and plantarflexion. In some examples, the wearer's force and motion measurements are obtained before a custom plate is manufactured for the user. In other examples, the plate is manufactured in stiffness increments to provide semi-custom footwear, allowing individual wearers to select the appropriate stiffness.

[0070] Various alternative methods for additive manufacturing of plates for footwear articles according to this disclosure may include adhesive spraying, direct energy deposition, selective laser melting (SLM), fused deposition modeling (FDM), electron beam melting, laser bed melting (LPBF), ultrasonic additive manufacturing, material extrusion, material spraying, Joule printing, electrochemical deposition, cold spray metal printing, DLP metal printing, ultrasonic consolidation or ultrasonic additive manufacturing (UAM), LENS laser-based printing, barrel photopolymerization, sheet lamination or electron beam freeform manufacturing (EBF3).

[0071] As used herein, the term "stiffness" refers to the way a component resists deformation when a load is applied. In particular, this paper will discuss the "stiffness" of elastic deformation, which is considered non-destructive temporary deformation. Therefore, "stiffness" can be used in conjunction with the terms "resistance" and "strength." Furthermore, this paper can describe "stiffness" according to various directions, deformation types, material properties, etc. For example, the "stiffness" of a component can be decomposed into bending stiffness, tensile stiffness, or shear stiffness. Moreover, the "stiffness" of a component is related to the elastic modulus (E) of the material used, which can be quantified using Young's modulus formula: Where σ is uniaxial stress, i.e., force per unit surface area, and ε is strain, i.e., proportional deformation. For clarity, the term "stiffness" may be further specified in this document to refer to specific types of resistance, such as bending resistance (BR) and torsional resistance (TR). In some cases, the "stiffness" of a component can be quantified or calculated relative to size, mass, or volume. For example, the "stiffness" of a component can be measured in Newtons per millimeter (N / mm) or gigapascals (GPa), but other units may also be used. Furthermore, "stiffness" can be qualitatively expressed as high or low, and is also understood to relate to various aspects of footwear, such as comfort, support, stability, rigidity, and durability.

[0072] Figure 4 An exploded view of a footwear article 100 including a plate 200 according to an embodiment of the present disclosure is shown. The plate 200 includes a top side 204 opposite to a bottom side 208 and a rear section 212, an arch section 216, and a forefoot section 220. The rear section 212, when incorporated into the shoe 100, may extend through at least a heel region 112 of the shoe 100 and may correspond to a portion of the plate 200 located near the heel of the foot, as described earlier herein. The arch section 216 of the plate 200 is adjacent to and abuts the rear section 212 and corresponds to a portion of the plate 200 located near a midfoot region 110 of the shoe 100, which surrounds the arch and bridge of the foot. The forefoot section 220 of the plate 200 is adjacent to and abuts the arch section 216 and corresponds to a portion of the plate 200 located near a forefoot region 108 of the shoe 100, which surrounds the toes, the ball of the foot, and the joints connecting the metatarsals to the toes or phalanges. The plate 200 defines a longitudinal reference axis 224, which intersects the plate 200 at the heel end 146 and the toe end 140. In addition, the plate 200 defines a central axis 228, which bisects the heel end 146 and the toe end 140, such that the reference axis 224 extends at an angle relative to the central axis 228.

[0073] In the illustrated embodiment, the plate 200 is configured to be removably attached to the midsole 172 of the footwear article 100. In other words, the plate 200 can be inserted into and removed from the cavity 270 within the midsole 172 via a slot 272. Figure 4 As shown, cavity 270 is entirely within midsole 172, and groove 272 is located in heel region 112 of footwear article 100, adjacent to or on heel end 146. In some embodiments, groove 272 may be located in different parts of footwear article 100, namely the outer side 116, the inner side 118, or the toe end 140. Therefore, it is conceivable that plate 200 can be removably attached to midsole 172 at any location.

[0074] Still referencing Figure 4The cavity 270 is sized and shaped to accommodate the plate 200. Therefore, a user can slide the plate 200 through the slot 272 and into the cavity 270. In some embodiments, the cavity 270 may be substantially the same size and shape as the plate 200. Furthermore, in some embodiments, the cavity 270 may be different in size and shape from the plate 200. For example, in some implementations, the cavity 270 may be deformable, and the size of the cavity 270 may be slightly smaller than the plate 200. Therefore, when a user inserts the plate 200 into the cavity 270, the cavity 270 will expand and securely hold the plate 200 therein, i.e., the midsole 172 holds the plate 200 therein.

[0075] Still referencing Figure 4 The plate 200 can be securely held within the cavity 270 of the midsole 172. In some embodiments, the plate 200 may be securely held within the cavity 270 by a friction fit or engageable component, i.e., the plate 200 is in contact with the midsole 172. Furthermore, in some embodiments, the plate 200 may be fastened to the midsole 172 by various fastening mechanisms, such as fasteners, cables, clamps, sliding fastening systems, or hooks. Additionally, in some embodiments, the plate 200 may be fastened within the cavity 270 by Velcro®, magnetic elements, or interlocking components. Therefore, it is conceivable that the plate 200 can be removably secured within the cavity 270 in any conventional manner known to those skilled in the art.

[0076] Still referencing Figure 4 The plate 200 is configured to be removably embedded within the midsole 172, as indicated by the dashed exploded line, which indicates the path through which the plate 200 can be inserted. However, in some embodiments, the plate 200 may be mounted between the midsole 172 and the upper 102, or between the midsole 172 and the outsole 174, or the plate 200 may be configured to be attached to the outsole 174 of the upper 102, or the plate 100 may be included as part of the upper 102.

[0077] As described above, plate 200 is configured to be removably attached to midsole 172. Therefore, as will be discussed in more detail herein, once plate 200 has been used over time, the user can remove plate 200 from footwear item 100 and replace it with a different or new plate 200. Thus, the user does not need to purchase entirely new shoes; they can simply remove plate 200 and replace it with a new one. In some embodiments, the new plate 200 may be smaller than the original plate 200 or have a different size. Furthermore, in some embodiments, the new plate 200 may include different materials or strength properties than the original plate 200. Therefore, it is noteworthy that plate 200 may include various sizes and shapes and still be able to be secured within the cavity 270 of midsole 172. Moreover, in some embodiments, multiple plates 200 can be used to provide the user with different performance characteristics. For example, if the user is preparing for a long-distance running race, wearing a reinforced footwear item 100 may be beneficial. Therefore, a user can insert a plate 200 with higher stiffness for training matches, and then replace it with a plate 200 with lower stiffness before the match. Alternatively, a user can insert a plate 200 with higher stiffness before the match, and then replace it with a plate 200 with lower stiffness after the match. Thus, the plate 200 in the footwear item 100 can be replaced with various other plates 200 to customize to the user's needs.

[0078] For clarity, this disclosure refers to the reference directional coordinates X, Y, and Z. Specifically, the X direction corresponds to the outer-to-inner direction orthogonal to the longitudinal direction extending from the longitudinal reference axis 224; the Y direction corresponds to the longitudinal direction parallel to the longitudinal reference axis 244; and the Z direction corresponds to the perpendicular direction perpendicular to the X and Y directions. Furthermore, the term "in-plane" as used herein refers to a two-dimensional plane extending in the X and Y directions, orthogonal to it in the Z direction. It should also be understood that the longitudinal reference axis 224 further defines a longitudinal reference plane extending perpendicularly in the Z direction. (See also...) Figure 1 and Figure 4 It should be understood that the longitudinal plane defined by the longitudinal axis L may be coplanar with or partially coplanar with the in-plane direction of the shoe 100. Furthermore, the vertical plane defined by the vertical axis V may extend in the Z direction and is generally perpendicular to the in-plane direction and the longitudinal plane.

[0079] Reference Figure 4 and Figure 6The footplate 200 defines a periphery 290 that curves outward from the heel end 146 toward the side 116 relative to the centerline axis 228 within the heel region 112 to at least partially define the rear section 212. The periphery 290 extends further along the side 116 toward the midfoot region 110 and curves outward relative to the centerline axis 228 to at least partially define the arch section 216. Furthermore, the periphery 290 extends within the forefoot region 108 and curves outward before curving inward toward the toe end 140 to at least partially define the fore section 220. Similarly, the periphery 290 curves outward from the heel end 146 toward the medial side 118 within the heel region 112 to at least partially define the rear section 212. The periphery 290 extends further along the medial side 118 toward the midfoot region 110 and curves outward to at least partially define the arch section 216. Furthermore, the periphery 290 extends within the forefoot region 108 and bends outward before curving inward toward the toe tip 140 to at least partially define the forefoot section 220. Thus, the periphery 290 extends continuously through the entire plate 200, from the rear section 212 to the front section 220 and vice versa, and from the outer side 116 to the inner side 118 and vice versa. In some embodiments, a plurality of locking elements, such as protrusions, holes, etc., may extend from or be positioned on portions of the periphery 290 to secure it to the midsole 172. For example, the periphery 290 of the plate 200 may include protrusions or convex members that interact with notches or concave members in the midsole 172 to securely hold the plate 200 within the midsole 172.

[0080] exist Figure 5In the illustrated embodiment, the plate 200 is embedded within the sole 104 of the footwear article 100, and more specifically, the plate 200 is embedded within the midsole 172 of the sole 104. Furthermore, the upper 102 includes an insole 126 arranged in a strobel configuration such that the insole 126 is spaced apart from and does not directly contact the plate 200. In other words, the insole 126 is configured to cover the plate 200 within the cavity 270, i.e., the plate 200 is not visible through the opening 166 of the upper 102. In some embodiments, the plate 200 may be embedded within the midsole 172 in a manner that allows a portion of the plate 200 to contact the insole 126 or the upper 102. Additionally, in some embodiments, a portion of the plate 200 may contact the outsole 174. In other embodiments, the plate 200 may be provided as part of the upper 102. For example, the plate 200 may be included as part of the insole 126, or inserted into the cavity 106 of the footwear 100 similar to a conventional orthotic insert. In some embodiments, plate 200 may include the entire sole structure 104 of footwear 100, such that footwear 100 comprises only the upper 102 and plate 200. In the illustrated embodiment, a vertical plane V is disposed at the center between the outer side 116 and the inner side 118 of plate 200, and a horizontal plane H is disposed perpendicular to the vertical plane V and tangent to or coplanar with a portion of the bottom side 208 of plate 200. In this particular example, plate 200 has a geometry in which the top side 204 of plate 200 is curved relative to the horizontal plane H between the inner side 118 and the outer side 116. Furthermore, the bottom side 208 defines a varying curvature relative to the horizontal plane H between the outer side 116 and the inner side 118. Additionally, the periphery 290 of plate 200 is straight along the outer side 116 and the inner side 118, i.e., substantially parallel to the vertical plane V. In some embodiments, the periphery 290 of plate 200 may be curved, arched, or angled.

[0081] Still referencing Figure 5 The plate 200 is typically curved between the inner side 118 and the outer side 116, and also curved relative to the surrounding components of the footwear 100. For example, the plate 200 curves downward toward the horizontal plane H between the outer side 116 and the vertical plane V, and then curves upward away from the horizontal plane H between the vertical plane V and the inner side 118, such that the plate 200 is convexly curved relative to the horizontal plane H. Because... Figure 5 The horizontal plane H is tangent to the outsole 174, so the plate 200 is also convexly curved relative to the outsole 174. However, the plate 200 is concavely curved relative to the upper 102, such that the plate 200 is curved furthest from the upper 102 near the vertical plane V, and closest to the upper 102 on the inner side 118 and outer side 116. In some embodiments, the plate 200 may be curved in the opposite direction to that shown, i.e., comprising a concave curve relative to the outsole 174. Furthermore, in some embodiments, the plate 200 may be substantially flat, i.e., parallel or substantially parallel to the horizontal plate H. Furthermore, in Figure 5 In the footwear article 100, the insole 126 and plate 200 are depicted as having generally similar curvatures, although other configurations are possible. Furthermore, the midsole 172 at least partially surrounds the plate 200 and defines different curvatures above and below the plate 200, as shown, these curvatures differing from the curvature of the plate 200. In the illustrated embodiment, the insole 126, midsole 172, plate 200, and outsole 174 all fit together to conform to each other's curvatures, such that there are no gaps or voids between them (except for the cavity 270 once the plate 200 is removed). However, it should be understood that gaps or voids may form between one of the insole 126, midsole 172, plate 200, and outsole 174, such that the curvature of the insole 126 does not conform to the curvature of the midsole 172, and so on.

[0082] Still refer to Figure 5 Plate 200 is typically positioned in the middle of midsole 172, and plate 200 does not extend the entire width of sole structure 104, i.e., the width measured parallel to horizontal plane H. For example... Figure 5 As shown, the plate 200 includes a plate width PW, and the sole structure 104 includes a sole width SW. In a preferred embodiment, the plate width PW is smaller than the sole width SW along the entire plate 200 and sole structure 104. However, in some embodiments, the plate width PW may be equal to or greater than the sole width SW (see...). Figure 8 Therefore, in some embodiments, the plate 200 can be seen from the outside of the footwear article 100 on the outer side 116 and / or inner side 118 of the sole structure 104 (see...). Figure 8 However, as Figure 5 As shown, the plate 200 is enclosed within the midsole 172, meaning that the plate 200 is completely surrounded by the midsole 172 except for the groove 272. As described herein and... Figure 5 and Figure 6 As shown, the plate width PW varies depending on the portion of plate 200; that is, the rear section 212 of plate 200 has a thinner plate width PW than the arch section 216 of plate 200. Therefore, in some embodiments, the widest portion of plate 200, i.e., parallel to... Figure 5 The portion measured at the horizontal plane H is smaller than the narrowest part of cavity 270, which is similar to the plate width PW parallel to... Figure 5 The portion measuring the horizontal plane. In this way, plate 200 can slide completely into cavity 270 without getting stuck.

[0083] As described above, the midsole 172 can deform near the cavity 270. Therefore, in some embodiments, the width of the cavity, i.e., parallel to... Figure 5The width measured in the horizontal plane H can be smaller than a portion of the plate 200. For example, the width of the cavity 270 in the heel region 112 can be smaller than the width of the cavity 270 in the forefoot region 108. Therefore, in order for the user to insert the plate 200 into the cavity, the user needs to apply additional force to the plate 200 during installation so that the arch section 216 of the plate 200, i.e., the widest part of the plate 200, passes through the narrower area in the heel region 112 of the cavity 270. When additional force is applied, the midsole 172 around the heel region 112 can deform to allow the arch section 216 of the plate 200 to pass through. Once the arch section 216 of the plate 200 has passed through, the heel region 112 of the midsole 172 can snap back into its original configuration to secure the rear section 212 of the plate 200. This deformation helps to secure the plate 200 within the cavity 270 and prevents the plate 200 from slipping out during use.

[0084] In some embodiments, the plate width PW is between about 5% and about 105% of the sole width SW. In some embodiments, the plate width PW is between about 50% and about 90% of the sole width SW. In some embodiments, the plate width PW is between about 60% and about 85% of the sole width SW. In some embodiments, the plate width PW is less than about 100% of the sole width SW, or less than about 90% of the sole width SW, or less than about 80% of the sole width SW, or less than about 70% of the sole width SW, or less than about 60% of the sole width SW, or less than about 50% of the sole width SW.

[0085] Reference Figure 6 The image shows a top view of plate 200. (See image for details.) Figure 6 As shown, the plate 200 includes a general shape corresponding to the shape of the user's foot. However, as will be discussed in more detail herein, the plate 200 can include various shapes and configurations. Now refer to... Figure 4 and Figure 6 To insert the plate 200 into the midsole 172, the user can grasp or pinch the rear section 212 of the plate 200 and position the front section 220 of the plate 200 aligned with the groove 272 of the midsole 172 (see...). Figure 4 Once the front section 220 is aligned with the groove 272, the user can apply force to the plate 200 and push it into the groove 272. The plate 200 will continue to slide into the groove 272 and cavity 270 until the front section 220 of the plate 200 contacts the end wall (not shown) of the cavity 270. Once the plate 200 contacts the end wall, the plate 200 is fully secured within the cavity 270 of the midsole 172. As described above, in some embodiments, the plate 200 can be fastened to the midsole 172 by various engagement components.

[0086] In some embodiments, the plate 200 can be inserted into the midsole 172 from the top of the footwear article 100. Specifically, in some embodiments, the insole 126 can be removably attached to the sole structure 104, and once the insole 126 is removed, the plate 200 can fall into or be inserted into the cavity 270. Therefore, once the insole 126 is removed from the sole structure 104, the cavity 270 can be exposed. Once the plate 200 is secured within the midsole 172, the insole 126 can be reattached to the sole structure 104, thereby securing the plate 200 within the midsole 172. In this embodiment, the sole structure 104 may not include the groove 272 outside the midsole 172, meaning that once the insole 126 is attached to the sole structure 104, the cavity 270 will be completely closed.

[0087] Furthermore, in some embodiments, plate 200 may have a smaller longitudinal length than shown, i.e., a length parallel to the longitudinal axis L. For example, in some embodiments, plate 200 may not have a longitudinal length similar to the longitudinal length of sole structure 104, i.e., a length parallel to the longitudinal axis L. Conversely, in some embodiments, the longitudinal length of plate 200 may be less than the longitudinal length of sole structure 104. Therefore, in some embodiments, the rear section 212 of plate 200 may not be located near groove 272 and / or the periphery 290 of plate 200 may not be located adjacent to or close to the periphery of sole structure 104. Instead, plate 200 may be positioned inward from the periphery of sole structure 104. In such embodiments, a user may need to use a tool to remove plate 200 from sole structure 104. The tool may have a hook or locking element that can pull plate 200 out of cavity 270. The tool may also be used to detach plate 200 from sole structure 104. Furthermore, in some embodiments, the tool may have a magnet that can be attached to the plate 200 and remove the plate 200 from the cavity 270. Additionally, in some embodiments, the tool may be used to latch and / or secure the plate 200 to the sole structure 104, i.e., the tool may be used to insert the plate 200 into the cavity 270.

[0088] In some embodiments, the longitudinal length of the plate 200 may be less than about 99% of the longitudinal length of the sole structure 104, or less than about 90% of the longitudinal length of the sole structure 104, or less than about 80% of the longitudinal length of the sole structure 104, or less than about 70% of the longitudinal length of the sole structure 104, or less than about 60% of the longitudinal length of the sole structure 104, or less than about 50% of the longitudinal length of the sole structure 104, or less than about 40% of the longitudinal length of the insole structure 104.

[0089] In certain embodiments, as described above, the plate 200 may be formed by an additive manufacturing process in which the various layers of the plate 200 are printed during a printing process, such as any additive manufacturing method disclosed above or in U.S. Patent Application No. 17 / 578,752, filed January 19, 2022, the entire contents of which are incorporated herein by reference. In some embodiments, the plate 200 may include multiple composite layers. In some embodiments, the plate 200 may be formed of a composite material or one or more layers of fibers, such as carbon fiber, aramid fiber (e.g., Kevlar®), boron fiber, glass fiber, natural fiber, and polymer fiber, or combinations thereof. In these embodiments, the fibers may be attached or bonded to a substrate of a plastic material, such as nylon, epoxy resin, or ultra-high molecular weight polyethylene (UHMWPE), or a textile material or composite material, and other suitable materials. In some embodiments, the plate 200 may be formed of a unidirectional tape comprising carbon fiber, aramid fiber (e.g., Kevlar®), boron fiber, glass fiber, polymer fiber, or any other material having high strength-weight characteristics. In some embodiments, the plate 200 may include reinforcing members to strengthen the plate 200. In a preferred embodiment, plate 200 may include a reinforcing member comprising carbon fiber.

[0090] As described herein, plate 200 may include an elliptical leaf spring design with extreme bending capacity. Therefore, plate 200 can act as a spring when the user runs or walks. As described in the gait phase section below, the purpose of plate 200 is to preload the spring when the heel leaves the ground during the human gait cycle, and unload the spring when the toes leave the ground. Since the primary leading spring cannot move the ground beneath the user, the spring moves the user. When the user's foot leaves the ground during the next step, this loaded spring releases its energy. Figure 4 As shown, the plate 200 is arched from the rear section 212 to the front section 220. This orientation follows the center of mass during the gait cycle, facilitating gait flow. Therefore, the user only needs to step on the plate 200 to preload it. When the plate 200 is oriented distally towards the toes, it increases the plantar flexion moment (rate and amount of downward force) on the lower metatarsal (bottom), propelling the user forward or upward, or any combination thereof, depending on the activity. For example, high jumpers primarily need to lift (or exert force) upward, long jumpers need to lift (or exert force) upward and move forward a certain distance, and sprinters only need to exert force forward.

[0091] The following describes the four (4) phases of the gait cycle with reference to plate 200 and its spring-like effect:

[0092] Heel strike: When the foot first makes contact with the ground while walking or running. Upon heel strike, the rear section 212 of the plate 200 deflects slightly to reduce impact and allow for a smooth flow into the next phase.

[0093] Forefoot strike: When the heel area 112 and the forefoot area 108 strike the ground simultaneously. At this time, the tibia and the user's center of gravity are passing over the foot. In the case of forefoot strike, the slight arch of the plate 200 from the rear section 212 to the front section 220 provides preload to increase the spring force into the next stage.

[0094] Heel off the ground: When the foot is bent, the heel area 112 is off the ground. When the heel is off the ground, at the maximum bending of the foot, the potential energy (PE) of plate 200 is stored and ready to be released.

[0095] Toe lift-off: When the foot leaves the ground to take the next step. When the toes lift off the ground, the potential energy stored in the ball of the foot and heel is released explosively, increasing the force and speed of foot flexion and extension, propelling the user forward or upward or a combination of both.

[0096] The combination of footwear 100 and board 200 facilitates the body's natural elasticity during gait. Therefore, since the ground beneath the user cannot move, it propels the user forward or upward. As described herein, the force generated by board 200 acting as a spring to propel the user (or any combination thereof) forward or upward is defined herein as a propulsive force.

[0097] Over time, plate 200 may deteriorate, and its performance may change due to repeated forces applied to it. In other words, after multiple gait cycles, the characteristics of plate 200 may weaken or diminish, for example, propulsion may decrease or weaken. In some cases, plate 200 may experience fatigue, and some deformation of plate 200 during gait cycles may become permanent, meaning plate 200 does not always spring back to its original orientation. In other words, plate 200 may lose stiffness over time. Therefore, plate 200 may wear down and provide less support, propulsion, and / or stiffness than initially provided. Therefore, it would be beneficial to replace plate 200 after a period of use without having to replace the entire footwear article 100. That is, the footwear article 100 of this disclosure may include replaceable plate 200 to provide effective support, propulsion, and / or stiffness to the user throughout the entire lifespan of the footwear article 100.

[0098] In some embodiments, after the plate 200 loses about 0.1% of its thrust, or about 1% of its thrust, or about 2% of its thrust, or about 5% of its thrust, or about 10% of its thrust, or about 20% of its thrust, or at least 0.1% of its thrust, or at least 1% of its thrust, or at least 2% of its thrust, or at least 5% of its thrust, or at least 10% of its thrust, or at least 20% of its thrust, the user can replace the plate 200.

[0099] Furthermore, as mentioned above, the board 200 may need to be replaced depending on the activity being performed. Therefore, users can have various boards 200 with different lengths, widths, curvatures, stiffnesses, materials, and angles, which can be replaced as needed based on the activity the user will be engaging in. For example, if a user wants to increase their vertical jump, such as when playing basketball, a board 200 that provides greater upward force during the "rebound" phase can be used instead of a board that provides greater forward force. Additionally, a stiffer board 200 can be used by users planning to run marathons or long-distance running. Furthermore, if a user wants a lighter footwear item 100, i.e., for walking, a lighter board can be used (or no board at all). Therefore, footwear item 100 can include various replaceable boards 200 that affect the performance of footwear item 100.

[0100] In some embodiments, as described above, the plate 200 can be customized during the manufacturing process to suit a user's specific characteristics or properties. For example, a user can purchase footwear item 100 that includes a universal plate 200. After purchase, the user can have their foot characteristics measured at a suitable location, such as foot size, foot profile, foot angle, arch, toe length, and gait cycle. Furthermore, the user can indicate what activities they plan to participate in and / or what performance values ​​they are looking for. After collecting and processing the data, the customized plate 200 can be manufactured using additive manufacturing (or conventional manufacturing) tailored to the user's specific characteristics. Once the customized plate 200 is manufactured, the user can remove the universal plate 200 from the footwear item 100 and replace it with the customized plate 200. Thus, the plate 200 can be specifically customized for the user to help them perform optimally in their desired activities. In some embodiments, a user can manufacture multiple plates 200, each specific to a particular activity or type of sport.

[0101] As described above, the plate 200 can deform through interaction with the sole 104 and experience stresses in one or more directions during use that can alter or affect performance, such as stiffness and propulsion. Such stresses arising from assembly with the footwear 100 can provide responsiveness benefits, enhancing the customization of the plate 200 within the footwear 100 when combined with the tuned stiffness and geometry of the plate 200. As used herein, the term "responsiveness" can refer to the plate 200's sensitivity to applied loads, i.e., external forces applied during use, whether the applied load is due to the user's weight or activities such as running, walking, jumping, changing direction, weightlifting, etc., and also to the plate 200's sensitivity to deformation in one or more directions. In some embodiments, the responsiveness of the plate 200 can vary along the forefoot 220, arch 216, and heel 212, and can vary between the outer side 116 and the inner side 118. In some cases, the arch section 216 of the plate 200 can be preloaded to have greater responsiveness, making the plate 200 more sensitive to walking activities that experience less deformation, while still providing greater propulsion and support benefits to the user. In some embodiments, the forefoot section 220 may have increased responsiveness to provide maximum propulsion when the user presses down during jumping activities.

[0102] In some embodiments, the plate 200 may be positioned at an angle between the upper 102 and the outsole 174, such that the forefoot section 220 is further from the upper 102 than the rearfoot section 212. This results in the rearfoot section 212 being positioned higher vertically relative to the forefoot section 220 and / or the arch section 216, i.e., elevated in the Z-direction. Therefore, the plate 200 can be configured to promote propulsion or rebound during use. Furthermore, the plate 200 may be formed with different shapes and curvatures along the reference axis 224 and / or between the inner side 118 and the outer side 116 to promote cushioning, propulsion, and support during use.

[0103] Reference Figure 4 and Figure 6The plate 200 may also include an indicator 320. In some embodiments, the indicator 320 may be located on the top side 204 or the bottom side 208 of the plate 200. The indicator 320 may include text, letters, or information about the characteristics of the plate 200. For example, the indicator 320 on the plate 200 may indicate the length of the plate 200, i.e., the longitudinal length of the plate 200, the stiffness or stiffness value of the plate 200, the material properties of the plate 200, the life of the plate 200, the width of the plate 200, the material used to manufacture the plate 200, the strength of the plate 200, the fatigue duration, and / or the propulsion force provided by the plate 200. In some embodiments, the indicator 320 may include color, notch, stripes, symbols, numbers, and / or letters. In some embodiments, the indicator 320 may indicate when the plate 200 is expected to deteriorate or when the plate 200 has already deteriorated. In some embodiments, the indicator 320 may be a chemical reaction occurring within the plate 200. For example, once plate 200 begins to deteriorate, or as the characteristics of plate 200 (e.g., stiffness, spring effect, and / or propulsion) change, plate 200 may undergo a chemical reaction, instructing the user that plate 200 should be replaced. In some embodiments, plate 200 may change color (or display a symbol) through a chemical reaction once it is time to replace it. Therefore, indicator 320 may indicate a depletion state. In some embodiments, indicator 320 may include a sensor that notifies the user once plate 200 should be replaced.

[0104] Reference Figure 7 Another embodiment of the plate 400 is provided for use within the sole structure 402 of the footwear article 100. Figure 7 Plate 400 and sole structure 402 are similar to plate 200 and sole structure 104; therefore, similar reference numerals are used to indicate similar elements. Furthermore, it should be noted that plate 400 can function in a similar manner to plate 200. Therefore, plate 400 can act as a spring and provide propulsion to the user. Moreover, plate 400 can be customized and manufactured in a manner similar to that described above with respect to plate 200.

[0105] Still refer to Figure 7 The plate 400 includes an inner fork 410 and an outer fork 412, which are separated by a gap 414 within the front section 220 of the plate 400. The plate 400 narrows relative to a reference axis 224 that moves longitudinally toward the heel end 146, i.e., measured in the X direction. That is, the plate 400 narrows from the front section 220 to the arch section 216, and also from the arch section 216 to the rear section 212. In the illustrated embodiment, the sole structure 402 also includes an outsole 430 and a midsole 440 to which the plate 400 is connected.

[0106] Similar to plate 200, plate 400 can be removably attached to sole structure 402. Therefore, if needed, plate 400 can be removed from footwear 100 and replaced with another plate 400. However, as discussed in further detail below, when plate 400 is attached to footwear 100, a portion of plate 400 lies beneath midsole 440. Specifically, as... Figure 7 As shown, the inner fork 410 and outer fork 412 of the plate 400 are located between the midsole 440 and outsole 430 of the sole structure 402. Therefore, the sole structure 402 does not include the cavity 270 within the midsole 440, similar to sole structure 104 (see...). Figure 1-6 ).

[0107] Reference Figure 1-3 7. Plate 400 is configured as part of sole structure 402, and is assembled with upper 102. Specifically, plate 400 is configured to be located between outsole 430 and upper 102, such that plate 400 contacts both outsole 430 and upper 102. For this purpose, plate 400 is configured to extend through midsole 440, and specifically, the rear portion 212 of plate 400 extends through groove 460 formed through midsole 440 (see...). Figure 7 (The arrow in the diagram). In the illustrated embodiment, the plate 400 gradually bends relative to the longitudinal axis L along the front segment 220 and the arch segment 216, and the plate 400 has an increased curvature relative to the longitudinal axis L along the arch segment 216 and the rear segment 212 compared to the curvature in the front segment 220.

[0108] During assembly, the rear section 212 of plate 400 is placed on platform 470, flush with the bottom (bed) 474 of midsole 440. When upper 102 is attached to midsole 440, insole 126 of upper 102 is positioned along bottom 474 and the rear section 212 of plate 400. Therefore, when assembling sole structure 402, plate 400 is positioned at a downward angle relative to longitudinal axis L extending in the X and Y directions, and is coplanar with at least a portion of bottom 474 of midsole 440 and / or insole 126 of upper 102. The downward angle is at least approximately 5 degrees, but can also be 10 degrees or greater. At this downward angle, combined with a specific curvature, plate 400 is configured to deflect under applied load during use, causing plate 400 to spring back, thereby providing propulsion for the user's gait under light loads, such as simply walking strides, similar to plate 200 described above. In combination with the specific shape and size of the plate 400, as described above, the plate 400 is arranged within the sole structure 402 to increase responsiveness, thereby making it easier to generate propulsion under a lighter applied load compared to a plate laid flat along the midsole 440.

[0109] As described above, the plate 400 is configured to be removed from the sole structure 402. In some embodiments, the midsole 440 may be configured to be detached from the outsole 430 and / or the upper 102 to allow the plate 400 to be inserted therein. In a non-limiting example, the midsole 440 of the sole structure 402 may be hinged to the outsole 430, such that an opening can be formed between the midsole 440 and the outsole 430 to insert the plate 400 therein. In some embodiments, the footwear article 100 may include a cable system to release the midsole 440 from the upper 102 and / or the outsole 430 so that a user can insert the plate 400 therein. Furthermore, in some embodiments, the upper 102 may be directly secured to the outsole 430, allowing the midsole 440 to be completely removed from the footwear article 100. In such an example, a user can remove the midsole 440 from the footwear article 100 and then replace the plate 400. In other words, the midsole 440 can be removed from the footwear item 100, and then a different plate 400 can be fixed to the midsole 440 via the slot 460. The midsole 440 and the newly added plate 400 can then be fixed to the footwear item 100.

[0110] Reference Figure 8 and Figure 9 Another embodiment of a plate 500 within a sole structure 502 for footwear articles 100 is provided. Figure 8 Plate 500 and sole structure 502 are similar to plate 200 and sole structure 104; therefore, similar reference numerals are used to indicate similar components. Furthermore, it should be noted that plate 500 can function in a similar manner to plates 200 and 400. Thus, plate 200 can act as a spring and provide propulsion to the user. Moreover, plate 500 can be customized and manufactured in a manner similar to that discussed above regarding plates 200 and 400.

[0111] Still referencing Figure 8 and Figure 9 The sole structure 502 includes an outsole 510, a plate 500, a heel cushioning member 512, a heel support collar 514, and a midsole 516. The plate 500 includes a base 530 and an arched, curved, or C-shaped rear portion 532, which connects to the base 530 near the heel end 146 of the sole structure 502. The rear portion 532 includes an upwardly extending flange 536 opposite the base 530. The base 530 slopes downward at an angle from the rear portion 532 in the rear section 212 of the plate 500. In other words, the base 530 of the plate 500 slopes downward as it extends from the rear portion 532 relative to the longitudinal axis L. The plate 500 flattens in the arch section 216 of the plate 500, i.e., generally parallel to the longitudinal axis L, and then has a slightly upward angle or slope towards the front section 220 of the plate 500. Figure 8As shown, plate 500 is visible from the outside of midsole 516. Therefore, plate width PW is typically the same as (or greater than) sole width SW. In some embodiments, plate 500 may not be visible from the outside of sole structure 502 or midsole 516.

[0112] Still referencing Figure 8 and Figure 9 The midsole 516 includes an upwardly extending sidewall 550, and an upwardly extending flange 536 may surround the sidewall 550 when the plate 500 is attached to the sole structure 502. In some embodiments, the plate 500 may not include the upwardly extending flange 536 on the rear portion 532. As described herein, portions of the plate 500 may be located above and below the midsole 516 at specific locations along the sole structure 502. For example, near the heel region 112 of the sole structure 502, the base 530 of the plate 500 is located below the midsole 516, and the upwardly extending flange 536 of the plate 500 is located above the midsole 512. In some embodiments, the base 530 of the plate 500 may be located within the midsole 516, rather than below it. Furthermore, in some embodiments, a portion of the base 530 of the plate 500 may be located within the midsole 516, while a portion of the base 530 of the plate 500 may be located below the midsole 516.

[0113] Similar to plates 200 and 400, plate 500 is configured to be removably attached to sole structure 502. Therefore, if needed, plate 500 can be removed from sole structure 502 and footwear item 100 and replaced with another plate 500. Figure 9 As shown, the plate 500 can slide out (and be inserted into) the heel area 112 of the footwear article 100. The rear portion 532 of the plate 500 can serve as a handle or grip to assist the user in removing and inserting the plate 500. Specifically, the user can grasp the rear portion 532 to remove the plate 500 from the sole structure 502. Alternatively, the user can grasp the rear portion 532 and use it to insert the plate 500 into the sole structure 502. In some embodiments, the plate 500 may not include the rear portion 532. For example, the plate 500 may end before the heel area 112 of the footwear article 100. Furthermore, it is contemplated that the rear portion 532 may include different shapes or configurations as it extends outward from the sole structure 502. In some embodiments, the plate 500 may engage a portion of the midsole 516 to lock the plate 500 in place within the sole structure 502.

[0114] As described herein, plates 200, 400, and 500 may be used in various configurations and / or shapes. Therefore, plates 200, 400, and 500 may be specifically designed to provide advantageous features to the user. In some embodiments, plates 200, 400, and 500 may be similar to the plates disclosed in U.S. Patent Application No. 17 / 082,327, filed October 28, 2020, the entire contents of which are incorporated herein by reference.

[0115] Figure 10 A flowchart depicts a process 600 using a modular board system. Process 600 can be used with any of the boards 200, 400, or 500 of the footwear article 100 described above. In some embodiments, boards 200, 400, and 500 can be interchanged or replaced with different boards 200, 400, and 500. For example, board 200 in footwear article 100 can be replaced with board 500. Although referenced... Figure 10 The flowchart shown illustrates the example process, but various other methods using a modular board system can also be used. For example, the execution order of blocks can be rearranged, changed, eliminated, and / or combined to execute process 600.

[0116] In step 602, process 600 includes providing a footwear article, such as footwear article 100. In some embodiments, footwear article 100 may include a cavity 270 to receive plates 200, 400, 500. In step 604, process includes providing a first plate (i.e., plate 200, 400, 500) having a first indicator (i.e., indicator 320). Furthermore, in step 606, process 600 includes demonstrating (providing) a second plate, i.e., plate 200, 400, 500 having a second indicator, i.e., indicator 320. The first plate and the second plate may include any of the plates 200, 400, 500 disclosed herein, and the first indicator and the second indicator may be similar to the indicator 320 disclosed herein. In some embodiments, the first plate may be different from the second plate, and the first indicator may be different from the first indicator.

[0117] In step 608, process 600 includes positioning the first plate within a cavity (e.g., cavity 270) of the footwear article (i.e., footwear article 100). Specifically, as described above, the user can insert plates 200, 400, and 500 into cavity 270 to secure plates 200, 400, and 500 to the footwear article 100. In step 610, process 600 includes circulating the first plate until a first indicator indicates a depletion state. Specifically, the user can continue to use and wear the footwear article 100 with plates 200, 400, and 500 until the indicator 320 on plates 200, 400, and 500 indicates a depletion state. As described above, this depletion state may occur when plates 200, 400, and 500 lose some stiffness or degrade in a particular way. In some embodiments, the depletion state may simply occur after the user has taken a certain number of steps. For example, the exhaustion state could be when a user walks approximately 3 million steps, or approximately 2 million steps, or approximately 1 million steps, or approximately 750,000 steps, or approximately 500,000 steps, or approximately 100,000 steps, or at least 100,000 steps, or at least 250,000 steps, or at least 500,000 steps, or at least 750,000 steps, or at least 1 million steps, or at least 2 million steps, or at least 3 million steps using footwear item 100 and board 200, 400, 500.

[0118] In step 612, process 600 includes replacing the first plate with a second plate within the cavity of the footwear article. Specifically, once the indicator indicates a depletion state, the user can replace plates 200, 400, and 500 with another plate 200, 400, or 500. In some embodiments, the user can replace plates 200, 400, and 500 by removing them from the cavity 270 via slot 272 and inserting a new plate 200, 400, or 500 therein. The second plate can then be used for an extended period until the second indicator indicates that it should be replaced. The user can then replace the second plate with a third plate. This process 600 can be repeated for multiple plates over time.

[0119] Reference Figure 11 A modular board kit 700 is shown. Kit 700 may include one or more boards 200, 400, 500. In this embodiment, kit 700 includes a first board 702a, a second board 702b, and a third board 702c. As described herein, boards 702a, 702b, and 702c are similar to board 200. However, in some embodiments, kit 700 may include boards similar to those described above. Figure 7-9The aforementioned boards 400 and 500 include boards 702a, 702b, and 702c. In some embodiments, kit 700 may include various boards 702a, 702b, and 702c having various performance characteristics. Therefore, a user may be able to purchase kit 700 and replace their boards 702a, 702b, and 702c within footwear item 100. In a non-limiting example, each board 702a, 702b, and 702c in kit 700 may be used for different activities. For example, one of the plates 702a, 702b, and 702c in kit 700 may be used for long-distance running, for example, a stiffer plate; one of the plates 702a, 702b, and 702c in kit 700 may be used for sprinting; one of the plates 702a, 702b, and 701c in kit 700 may be used for jumping, for example, for greater upward propulsion; and / or one of the plates 702a, 702b, and 702c in kit 700 may be used for walking, for example, a less stiff plate. As described above, a user can use kit 700 to replace the plates 702a, 702b, and 702c in footwear item 100. In some embodiments, the plates 702a, 702b, and 702c in kit 700 may include different thicknesses, lengths, widths, strengths, and / or material properties. For example, the second plate 702b may include a smaller length, and the third plate 702c may be thicker. In some embodiments, the plates 702a, 702b, and 702c in kit 700 may be formed of different materials or have different reinforcing members. In some embodiments, kit 700 may include different types of plates 702a, 702b, and 702c; for example, kit 700 may include plate 200, plate 400, and / or plate 500. Therefore, kit 700 allows for additional user customization and a better user experience. As described herein, in some embodiments, kit 700 may include 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, or 12 plates 200, 400, 500, 702a, 702b, and 702c.

[0120] Reference Figure 12 Another embodiment of the sole structure 802 with cavity 808 of footwear article 100 is provided. Figure 12 Cavity 808 and sole structure 802 are similar to cavity 270 and sole structure 104; therefore, similar reference numerals are used to indicate similar elements. Figure 12The illustration shows the interior of a cavity 808 within a sole structure 802, with a cavity wall 812 forming the cavity 808 within the sole structure 802. In some embodiments, a plurality of fingers 816 may extend from the cavity wall 812. Specifically, a plurality of fingers 816 may extend from the cavity wall 812 and into the cavity 808. In the illustrated embodiment, each of the plurality of fingers 816 is generally cylindrical or conical and includes a base or fixed end 820 and a tip or free end 824. In some embodiments, each of the plurality of fingers 816 may be formed of various shapes and sizes, or may include additional retaining features (not shown) for engagement with any of the plates 200, 400, 500, 702a, 702b, 702c, such as a notch on the tip 824 of the finger 816.

[0121] Still refer to Figure 12 Multiple fingers 816 are configured to pivot about a base 820. In other words, the multiple fingers 816 are biased so that they can move or pivot about the base 820 and quickly return to their original configuration after movement. Therefore, the multiple fingers 816 can act as... Figure 12 The spring shown is biased in its undeformed state. Figure 12 As shown, multiple fingers 816 can be positioned in various rows and columns. Although only three fingers 816 are shown per row and per column herein, it is conceivable that the sole structure 802 may include any number of fingers 816. In some embodiments, the sole structure 802 may include 10, 20, 30, 40, 50, 60, 70 or more fingers 816 extending from the cavity wall 812. Furthermore, in some embodiments, multiple fingers 816 may extend around or partially around the periphery of the cavity 808. Thus, in some embodiments, multiple fingers may extend from the top or bottom of the cavity wall 812.

[0122] Still refer to Figure 12 Multiple finger-like structures 816 can help to hold the plate 200 (see...) Figure 6 It is fixed within cavity 808. In particular, in some embodiments, the arch section 216 of plate 200 may be larger than the rear section 212 of plate 200 (see...). Figure 6 Therefore, in some embodiments, the width of the cavity, i.e., along... Figure 5The width measured parallel to the horizontal plane H in the shoe article 100 can be wider than the board width PW in some areas of the shoe article 100 to account for width differences in the board 200. To restrict movement of the board 200 in these wider cavity areas, the sole structure 802 can include a plurality of fingers 816. In other words, the board 200 can be secured within the cavity 808 by the plurality of fingers 816 to restrict lateral movement during use. In a non-limiting example, the fingers 816 can be located within the heel area 112 of the cavity 808. Therefore, when the user slides the board 200 into the cavity 808, the forefoot section 220 and the arch section 216 (which can be the widest part of the board 200 (see...))... Figure 6 The plurality of fingers 816 can be deformed and / or pivoted to allow access therethrough. Once the arch section 216 of the plate 200 has translated through the plurality of fingers 816, the plurality of fingers 816 can spring back to their original configuration and be secured to the rear section 212 of the plate 200, thereby restricting lateral or vertical movement of the front section 212 of the plate 200. In some embodiments, the rear section 212 of the plate 200 may be configured to be secured within a retaining feature (not shown) of the plurality of fingers 816, such as a notch. As described herein, in some embodiments, the sole structure 802 may include any number of fingers 816 on each side such that the rear section 212 of the plate 200 is located between the tips 824 of the plurality of fingers 814. As described herein, the fingers 816 may be located within any portion of the cavity 808 and may be used to retain or secure the plate 200 in the wider portion of the cavity 808.

[0123] Reference Figure 13 Another embodiment of the sole structure 902 is provided for use in footwear articles 100. Figure 13 The sole structure 902 is similar to the sole structure 104; therefore, similar reference numerals are used to indicate similar elements. For example... Figure 13 As shown, the sole structure 902 includes a groove 910 that defines an entrance to a cavity 920 within the sole structure 902. Similar to cavity 270, cavity 920 is located within the midsole 172 and configured to receive a plate 200 via the groove 910. In contrast to groove 272, groove 910 is located in the forefoot region 108 of the footwear article 100. Therefore, plate 200 can be inserted into the forefoot region 108 or toe tip 140 of the midsole 172. As described herein, cavity 920 and groove 910 may also be identical to cavity 270 and groove 272 as described above, except for their location on the footwear article 100. In some embodiments, groove 910 may be located on the outer side 116 or inner side 118 of the midsole 172.

[0124] Reference Figure 14 This illustrates another embodiment of footwear article 1000. Footwear article 1000 includes a sole structure 1002, an upper 1004, and a plate 1008. Figure 14Footwear article 1000 is similar to footwear article 100; therefore, similar reference numerals are used to indicate similar elements. Furthermore, it should be noted that plate 1008 may be similar to plates 200, 400, 500, 702a, 702b, and 702c described above, and functions in a similar manner. Figure 14 As shown, the sole structure 1002 includes a cavity 1020 that can receive a plate 1008 via a slot 1024. Similar to slot 272, slot 1024 is located within the heel region 112 of the midsole 172. The footwear article 1000 also includes a sheet-like overhang 1030 attached above the slot 1024. In some embodiments, the sheet-like overhang 1030 can be attached to the upper 1004 via a hinge 1034, such that the sheet-like overhang 1030 can rotate relative to the hinge 1034 between an open state and a closed state. As described herein, Figure 14 The sheet-like overhang 1030 is shown in the open position.

[0125] and Figure 14 To maintain consistency, the sheet-like overhang 1030 includes a sheet-like overhang wall 1038 and a sheet-like overhang housing 1042 extending from the sheet-like overhang wall 1038. The sheet-like overhang housing 1042 includes a sheet-like overhang cavity 1046 extending within the sheet-like overhang housing 1042. In a preferred embodiment, the sheet-like overhang cavity 1046 is configured to mate with the rear section 212 of the plate 1008. In other words, when the sheet-like overhang 1030 is in the closed state, the sheet-like overhang cavity 1046 is configured to retain a portion of the plate 1008 therein. Therefore, in conjunction with the above reference... Figure 12 Similar to the finger-like structure 816, the sheet-like overhang housing 1042 can restrict the lateral or vertical movement of the plate 1008 within the sole structure 1002. Therefore, the sheet-like overhang housing 1042 can extend around a portion of the plate 1008 and securely hold the plate 1008 within the sole structure 1002.

[0126] During use, the user can insert the plate 1008 into the cavity 1020 via the slot 1024 in a manner similar to that described for the plate 200. As described herein, the plate 1008 can only be inserted into the slot 1024 when the sheet-like overhang 1030 is in the open state (see [link to document]). Figure 14 Once the entire plate 1008 is positioned within the cavity 1020, the user can rotate the sheet-like hanging element 1030 (see...). Figure 14Arrow A) closes slot 1024. As described above, sheet-like pendant 1030 can rotate about hinge 1034. Therefore, when sheet-like pendant 1030 rotates about hinge 1033, the user can align the sheet-like pendant cavity 1046 of sheet-like pendant 1030 with a portion of the rear section 212 of plate 1008. Once plate 1008 is aligned with sheet-like pendant cavity 1046, the user can complete rotating sheet-like pendant 1030 to the closed state. When sheet-like pendant 1030 is rotated to the closed state, a portion of plate 1008 will be engaged within sheet-like pendant cavity 1046 to secure the rear section 212 of plate 1008 to sheet-like pendant 1030. As described above, sheet-like pendant 1030 can restrict the movement of plate 1008 and can further secure plate 1008 within midsole 172. Furthermore, once the sheet-like overhang 1030 is in the closed state, i.e., when the sheet-like overhang 1030 is flush with the heel area 112 of the footwear article 1000, the sheet-like overhang 1030 can be concealed in the groove 1024. As described herein, in some embodiments, the end 1050 of the sheet-like overhang 1030 may include various fastening systems to secure the sheet-like overhang 1030 to the sole structure 1002 in the closed state. For example, the sheet-like overhang 1030 may be secured to the sole structure 1002 in the closed state by clips, Velcro®, magnets, fasteners, and / or pins.

[0127] As described herein, the sheet-like pendant 1030 is shown having a hinge 1034 and is configured to be coupled to the upper 1004 and / or the sole structure 1002. In some embodiments, the sheet-like pendant 1030 may include a movable hinge and may be integral with the sole structure 1002 and / or the upper 1004 (see FIG. 15). Furthermore, in some embodiments, the hinge 1034 may be attached to the sole structure 1002. Furthermore, in some embodiments, the sheet-like pendant 1030 may be configured to move automatically between an open state and a closed state. Furthermore, in some embodiments, the sheet-like pendant 1030 may include a spring that biases the sheet-like pendant to an open or closed state. Furthermore, it is contemplated that the sheet-like pendant 1030 may include any shape or construction suitable for securely retaining the plate 1008 within the cavity 1020.

[0128] Reference Figure 15A and 15B Another embodiment of footwear article 1100 is shown. For example... Figure 15A As shown, footwear article 1100 includes sole structure 1102 and upper 1104. Figure 15AFootwear article 1100 is similar to footwear article 100; therefore, similar reference numerals are used to indicate similar elements. Similar to sole structure 104, sole structure 1102 includes a groove 1110 that defines an entrance to a cavity 1114 within the midsole 172. As described herein, cavity 1114 may be the same as cavity 270 described above. Groove 1110 is located in the heel region 112 of sole structure 1102 and extends onto a side 116 of sole structure 1102. In some embodiments, groove 1110 may extend a longer or shorter distance along the side 116 of sole structure 1102. Furthermore, in some embodiments, groove 1110 may extend along the inner side 118 of sole structure 1102.

[0129] Still refer to Figure 15A and 15B The sole structure 1102 includes a sheet-like overhang 1120 extending adjacent to the groove 1110. Specifically, the sheet-like overhang 1120 is configured to extend into and cover a portion of the groove 1110. The sheet-like overhang 1120 is configured to bend into and out of the cavity 1114 about a movable hinge 1124, forming a movable barrier within the cavity 1114. Therefore, the sheet-like overhang 1120 is configured to deform to allow access to the groove 1110 and the cavity 1114. (This is related to the above...) Figure 14 Similarly, the sheet-like overhang 1120 is configured to securely hold the plate 200 within the cavity 1114. Specifically, as... Figure 15B As shown, the sheet-like pendant 1120 may include a notch 1128 located on the inner surface 1132 of the sheet-like pendant 1120, the notch being configured to receive a portion of the plate 200. In a preferred embodiment, the periphery 290 of the rear section 212 of the plate 200 is configured to be secured within the notch 1128 of the sheet-like pendant 1120. As described above, once the plate 200 is inserted into the cavity 1114, the notch 1128 of the sheet-like pendant 1120 can help restrict movement of the plate 200. In some embodiments, the sheet-like pendant 1120 is configured to cover most or a portion of the groove 1110. In some embodiments, the sheet-like pendant 1120 may completely cover the groove 1110. Furthermore, in some embodiments, the notch 1128 may not be present in the sheet-like pendant 1120.

[0130] Still refer to Figure 15A and 15BDuring use, the user can insert the plate 200 into the cavity 1114 through the slot 1110 in a manner similar to that described above regarding plate 200, that is, aligning the front section 220 of the plate 200 with the slot 1110. When the user inserts the plate 200 into the slot 1110, the sheet-like overhang 1120 can rotate / deform to an open position via the movable hinge 1124 to allow the plate 200 to pass through. In some embodiments, the sheet-like overhang 1120 can be deformed simply by inserting the plate 200 into the cavity 1114. Alternatively, in some embodiments, the user can hold the plate 1120 in place when the plate 200 is inserted into the cavity 1114. Once the rear section 212 of the plate 200 has translated through the slot 1110, the sheet-like overhang 1120 can snap back into its original configuration in a closed position to secure the plate 200 therein. In some embodiments, the user may need to further position the plate 200 and / or the sheet overhang 1120 such that a portion of the plate 200 is located within the recess 1128 of the sheet overhang 1120. As described herein, Figure 15A and 15B The sheet-like overhang 1120 is shown in the closed position.

[0131] Still refer to Figure 15A and 15B The sheet-like overhang 1120 is formed internally together with the sole structure 1102. However, in some embodiments, the sheet-like overhang 1120 may be a separate component attached to or fixed to the sole structure 1102. As described herein, the sheet-like overhang 1120 is shown extending upward from the sole structure 1102. However, in some embodiments, the sheet-like overhang 1120 may extend downward from the sole structure 1104 to cover the groove 1110. Furthermore, in some embodiments, the sole structure 1102 may include a plurality of sheet-like overhangs 1120 extending over the groove 1110. For example, the sole structure 1102 may include two sheet-like overhangs 1120 located on opposite sides of the groove 1110, i.e., one sheet-like overhang extends upward from the sole structure 1102 and the other sheet-like overhang extends downward from the sole structure 1104, such that the distal edges of the sheet-like overhangs 1120 are adjacent to each other. In this embodiment, each sheet-like overhang 1120 can deform or rotate about a movable hinge (e.g., movable hinge 1124) to form a movable barrier. When the plate 200 is pushed into the slot 1110, the sheet-like overhang 1120 can shift / rotate about the movable hinge to allow access therein.

[0132] Reference Figure 16 Another embodiment of footwear article 1200 is shown. For example... Figure 16 As shown, footwear article 1200 includes sole structure 1202 and upper 1204. Figure 16Footwear article 1200 is similar to footwear article 100; therefore, similar reference numerals are used to indicate similar elements. Sole structure 1202 includes a groove 1210 that defines the entrance (shown as a dashed line) to cavity 1214. Compared to the previous embodiment, Figure 16 The groove 1210 extends within the heel region 112 and the outer side 116 of the midsole 172. In other words, the groove 1210 comprises a J-shape that extends around the heel region 112 and extends onto the side 116 of the sole structure 1202. In some embodiments, the groove 1210 may extend along the heel region 112 and the midfoot region 110 of the sole structure 1202. The groove 1210 allows the plate 200 to be inserted into the cavity 1214. As mentioned above, the width of the plate 200 can always vary to conform to the shape of the human foot. Therefore, in some embodiments, the arch section 216 and / or the forefoot section 220 of the plate 200 may be wider than the heel section 212. To account for this variation in width, in some embodiments, the sole structure 1202 may include grooves 1210 extending on multiple sides to facilitate insertion into and removal from the cavity 1214.

[0133] Still refer to Figure 16 During installation, the user can insert the board 200 into the slot 1210 at a certain angle, such as... Figure 16 As indicated by dashed arrow B. Once the front section 220 of the plate 200 contacts the wall 1218 of the end defining the cavity 1214, the user can rotate the plate 200 counterclockwise, i.e., the rear section 212 of the plate 200 rotates toward the heel end 146 of the footwear 1200, to slide the entire plate 200 into the cavity 1214 via the groove 1210. Once the plate 200 is positioned within the cavity 1214, the plate 200 is secured therein by the width difference of the cavity 1214. In some embodiments, such as Figure 16 As shown, the groove 1210 may be located within the heel region 112 and the inner side 118 of the sole structure 1102, rather than within the heel region 112 and the outer side 116.

[0134] As described above, footwear articles 100, 1000, 1100, and 1200 may include various configurations to accommodate various plates 200, 400, 500, 702a, 702b, 702c, and 1008. As described herein, any of the above embodiments can be interchanged with different embodiments. For example, any of the above-described sole structures 104, 402, 502, 802, 902, 1002, and 1202 can be used with any of the uppers 102, 1004, 1104, and 1204. Furthermore, any of the above-described grooves 272, 910, 1024, 1110, and 1210 and / or cavities 270, 808, 920, 1020, 1114, and 1214 can be used with any of the sole structures 104, 402, 502, 802, 902, 1002, 1102, and 1202. Therefore, it is conceivable that footwear articles 100, 1000, 1100, and 1200 may include various combinations of sole structures 104, 402, 502, 802, 902, 1002, 1102, and 1202, uppers 102, 1004, 1104, and 1204, grooves 272, 910, 1024, 1110, and 1210, and / or cavities 270, 808, 920, 1020, 1114, and 1214.

[0135] Furthermore, plates 200, 400, 500, 702a, 702b, 702c, and 1008 can be formed into various shapes and sizes and provided as part of footwear 100, 1000, 1100, and 1200, for example, in soles 104, 402, 502, 802, 902, 1002, 1102, and 1202 or uppers 102, 102, 1004, 1104, and 1204. Additionally, plates 200, 400, 500, 702a, 702b, 702c, and 1008 can be replaced by other plates 200, 400, 500, 702a, 702b, 702c, and 1008 with specific characteristics, performance indicators, or stiffness. Furthermore, plates 200, 400, 500, 702a, 702b, 702c, and 1008 can also be replaced after prolonged activity. Plates 200, 400, 500, 702a, 702b, 702c, and 1008 can be configured to be at least partially customized to influence or enhance requirements such as gait, stance, posture, propulsion, and agility. For example, plates 200, 400, 500, 702a, 702b, 702c, and 1008 can be configured to reduce pain and / or improve performance for users with medical problems or deformities. Additionally, the flexural resistance (BR) and torsional resistance (TR) of plates 200, 400, 500, 702a, 702b, 702c, and 1008 can be increased and customized for specific applications, with these resistances (BR and TR) taking into account and relating to the moment of inertia (MOI) and modulus of elasticity.

[0136] It is conceivable that any of the plates 200, 400, 500, 702a, 702b, 702c, and 1008 described in this disclosure may include embedded functionality in addition to the structural stiffness characteristics described above. For example, it is conceivable that plates 200, 400, 500, 702a, 702b, 702c, and 1008 may have or be modified to have conductive, thermally conductive, electrically insulating, heat-insulating, optically transmissive, or fluid-transmissive materials. Additionally or alternatively, a device (not shown) may be embedded within any plate of this disclosure. In one instance, the device (not shown) may be a sensor, such as a transducer, accelerometer, geolocation sensor, temperature sensor, humidity sensor, or moisture sensor. Furthermore, the device (not shown) may be capable of providing tactile feedback to a user, thereby notifying the user to avoid prolonged standing, sitting, or remaining still. Additionally, the device (not shown) may be an object or structural element, such as an inflatable or liquid-filled airbag or pod. Further envisioning is that the device (not shown) is capable of collecting and storing energy generated during use by deformation of the plate and / or shoe, for example, using a piezoelectric transducer.

[0137] Reference Figure 17 This provides another embodiment of footwear item 1300. Figure 17 Footwear article 1300 is similar to footwear article 100; therefore, similar reference numerals are used to indicate similar elements. For example... Figure 17As shown, footwear article 1300 includes a sole structure 1302 and an upper 1304. Footwear article 1300 may also include a plate 200 and a groove 272 within a cavity 270. However, in some embodiments, footwear article 1300 may not include the cavity 270 and / or the groove 272. Furthermore, in some embodiments, footwear article 1300 may be manufactured to include a plurality of markings thereon, including a first marking 1310 positioned adjacent to the midfoot region 110 and the heel region 112 (adjacent to the fastening system 180), a second marking 1312 positioned adjacent to the forefoot region 108 and the midfoot region 100, and a third marking 1314 positioned adjacent to the heel region 112. In the illustrated embodiment, the first marking 1310 is depicted as a logo or badge, although the first marking 1310 may be any symbol, code, password, mark, etc. The second and third markings 1312, 1314 are depicted as markings including wavy stripes or design features that reflect the outline of the upper 1304. The first, second, and third markings 1310, 1312, and 1314 are depicted as being disposed on the upper 1304, but other configurations are also possible. For example, one or more of the first, second, and third markings 1310, 1312, and 1314 may be located on the sole structure 1302. In some embodiments, by implementing the manufacturing method described above, the upper 1304 may be provided with the first, second, and third markings 1310, 1312, and 1314, such that the markings 1310, 1312, and 1314 are integrally formed with the upper 1304.

[0138] Furthermore, at least one of the markers 1310, 1312, and 1314 may contain a code or identifier, such as a machine-readable identifier. This code can be used to verify footwear item 1300, such that it is associated with a serial number or unique ID, token, or key, which can be scanned by, for example, a user device, such as a smartphone or a dedicated scanning device, such as a device employing Near Field Communication (NFC) technology. This code may correspond to encoded parameters stored in a remote host system (such as a digital platform), which may include the manufacturing date, manufacturing location, manufacturer identification, serial number or unique ID, a number associated with modified or customized features, aspects of footwear 1300 such as model and type, material, and a number associated with the quantity of items produced, such as limited edition products. Furthermore, this code may require the user device or scanning device to implement symmetric or asymmetric encoding algorithms or methods, such as Advanced Encryption Standard (AES), Rivest Shamir Adleman (RSA), Triple Data Encryption Standard (DES), Twofish algorithm, or any other suitable encryption method. In some cases, the code may be compatible with the hash function or algorithm implemented by the user device or scanning device, such as the Secure Hash Algorithm (SHA) or its equivalent published by the National Institute of Standards and Technology (NIST). It is expected that the user device or scanning device must run a specific operating system or application to implement the method for reading the code, although in some cases the code may be pre-programmed to automatically initialize a browser to search for a URL when detected by a sensor or camera, thereby accessing the software required to read the code.

[0139] This code can be similar to a barcode, a QR code, a password containing unique symbols, a unique combination of symbols, a color, and so on. Figure 17As shown, the second and third markings 1312 and 1314 include markings that incorporate stripes and design features that can be printed on or formed together with the upper 1304 according to an encoding algorithm that determines appropriate identifying aspects of the markings, such as the size, color, shape, and arrangement of the stripes and bands, to store and convey information. In some embodiments, markings 1310, 1312, and 1314 can be formed using conductive ink, conductive fabric, or ferromagnetic elements including codes. For example, markings 1310, 1312, and 1314 may include conductive ink arranged to include resistance values ​​at discrete, predetermined locations, such that combinations of these values ​​correspond to a serial number or unique ID associated with the footwear item 1300. In some cases, the upper 1304 is formed by embedded ferromagnetic or ferrimagnetic elements arranged to form magnetic regions with discrete predetermined magnetic values ​​(e.g., magnetic flux density values), allowing a magnetometer (e.g., a gaussmeter or teslameter) to measure these magnetic values, which combine to correspond to a serial number or unique ID associated with the footwear 1300. When scanned, this code can access a digital platform via a user device, or a remotely hosted secure website or address or application with at least a partial cryptographic key or token, such as a private key, corresponding to or unlocking digital assets, such as NFTs, which include a design pattern or unique ID or serial number associated with the footwear 1300. In this way, the footwear item 1300 can be authenticated by the user to ensure that the footwear item 1300 was manufactured by a specific manufacturer or brand. Furthermore, the code can provide authentication of custom features of the footwear item 1300. Additionally, as mentioned above, the sole structure 1302 may include similar machine-readable identifiers, such as... Figure 17 The markings 1310, 1312, and 1314 are shown. In some embodiments, plates 200, 400, 500, 702a, 702b, 702c, and 1008 may include similar machine-readable identifiers, such as markings 1310, 1312, and 1314. In some embodiments, markings 1310, 1312, and 1314 may be visible through a portion of the sole structure, for example, through a transparent or translucent window (not shown) formed in the outsole or midsole, to enable communication with a smartphone or scanner, etc. In some embodiments, markings 1310, 1312, and 1314 may be invisible and capable of communicating wirelessly (e.g., NFC or Bluetooth®). Furthermore, in some embodiments, indicator 320 may be a machine-readable identifier as discussed above regarding markings 1310, 1312, and 1314.

[0140] In some embodiments, the code on footwear item 1300 can be read by an authorized third party for tracking purposes. For example, entities throughout the supply chain, such as shipping companies, may scan the code for tracking. In some cases, the code can be used for inventory tracking purposes, allowing wholesalers, retailers, and accessory specialists to scan the code to update their inventory management systems. In some examples, a URL or digital platform may be able to track and log the identity of each entity that has gained access, such as a device ID or product ID. Furthermore, a user may access the URL before receiving footwear item 1300, for example, through a security notification via email or digital platform. Thus, in the event of loss or theft of footwear item 1300, the code can help the user locate the item or identify unauthorized access, such as by counterfeiters.

In some embodiments, the indicator 320 may be a machine-readable identifier that includes deterioration or depletion of boards 200, 400, 500, 702a, 702b, 702c, and 1008. Therefore, the indicator 320 can identify the degree of degradation or depletion of plates 200, 400, 500, 702a, 702b, 702c, and 1008, and whether new plates 200, 400, 500, 702a, 702b, 702c, and 1008 should be inserted into footwear items 100, 1000, 1100, 1200, and 1300. Furthermore, in some embodiments, the indicator 320 may be a machine-readable identifier that includes the performance and / or material characteristics of boards 200, 400, 500, 702a, 702b, 702c, and 1008, for use by racing authorities or governing bodies to ensure that boards 200, 400, 500, 702a, 702b, 702c, and 1008 are not unauthorized versions of boards 200, 400, 500, 702a, 702b, 702c, and 1008. For example, authorized personnel of the Boston Marathon® may be able to scan the indicator 320 on boards 200, 400, 500, 702a, 702b, 702c, and 1008 to determine whether boards 200, 400, 500, 702a, 702b, 702c, and 1008 are suitable for racing / performance. Furthermore, in some embodiments, the indicator 320 may be a machine-readable identifier with a token or link to the NFT. Therefore, the indicator 320 may allow a user to unlock or obtain the NFT, which may authenticate boards 200, 400, 500, 702a, 702b, 702c, and 1008. Additionally, in some embodiments, the user may authenticate boards 200, 400, 500, 702a, 702b, 702c, and 1008 in other ways, for example, by directing the user to a URL where the user can register boards 200, 400, 500, 702a, 702b, 702c, and 1008.Furthermore, in some embodiments, indicator 320 may be scanned by a third party, such as a racing authority or an entity in the supply chain (e.g., a retailer or distributor). Additionally, in some embodiments, indicator 320 allows a user to verify that boards 200, 400, 500, 702a, 702b, 702c, and 1008 are genuine, i.e., not counterfeit. As described herein, boards 200, 400, 500, 702a, 702b, 702c, and 1008 may include various markings 1310, 1312, and 1314, which are machine-readable identifiers similar to those discussed above regarding indicator 320.

[0142] Further envisioning, boards 200, 400, 500, 702a, 702b, 702c, and 1008 include a power storage unit 1320 (see...). Figure 16 Examples of such devices include batteries, capacitors, and supercapacitors. Therefore, boards 200, 400, 500, 702a, 702b, 702c, and 1008 can be removed to recharge or replace the power storage unit 1320. Furthermore, when a removed board is recharged or repaired, boards 200, 400, 500, 702a, 702b, 702c, and 1008 can be replaced with another board that includes the rechargeable power storage unit 1320. The power storage unit 1320 can be used to power circuitry (not shown) associated with various electronic features, such as lighting, displays, control modules, sensors, transmitters or receivers or transceivers, or combinations thereof, or any other electronic features provided on the footwear item 100.

[0143] In some embodiments, plates 200, 400, 500, 702a, 702b, 702c, and 1008 can be divided into discrete sub-parts corresponding to the user's foot area. (Refer to...) Figure 18 In one embodiment, the plate 1400 is laterally divided into a forefoot segment 1404, an arch or midfoot segment 1408, and a heel segment 1412. It is also conceivable that the plate 1400 can be longitudinally divided into portions corresponding to the medial side 118 and the lateral side 116, or along... Figure 3 The plate 1400 is divided by lines 144, 150, and 120. Additionally or alternatively, the forefoot segment 1404 of the plate 1400 may be configured as a plurality of longitudinal segments 1416, 1420, 1424, 1428, and 1432 corresponding to each corresponding phalanx 130 of the user's foot. It is conceivable that the thickness, material composition, stiffness, size, shape, and other properties of the plate 1400 may vary between the segments. Therefore, the footwear article 100 may include a plurality of slots 272, 910 (see...). Figure 1 and 13The size, shape, and position of the plate 1400 allow for the insertion and removal of each section or segment of the plate 1400. In some cases, a user may selectively insert all, some, or no sections of the plate 1400 for use with footwear 100. For example, a user requiring additional support in the midfoot area 110 may only wish to insert the midfoot section 1408 of the plate 1400. Additionally or alternatively, the user may be aware of the need for support along the big toe near the ball of the foot 132 (see...). Figure 3 Therefore, longitudinal segment 1416 can be installed in the forefoot area 108 of footwear article 100. In some embodiments, plate 1400 can be folded to increase stiffness or support in certain areas. For example, longitudinal segments 1416 and 1420 can be connected to each other along a movable hinge (not shown) or by fasteners, fibers, and / or stitching, so that a user can selectively fold one segment over the other and insert the combination into footwear article 100, thereby effectively increasing the stiffness or support of selected areas of the user's foot. In some embodiments, each part of plate 1400 is completely separate and distinct from each other. In some embodiments, at least some segments of plate 1400 can be connected to each other by a fragile portion (not shown), which allows the user to selectively keep the segments connected or separate the segments as needed.
