The handle is operably coupled to a cable that extends along the sole structure from the heel region to the midfoot region of the footwear. Rotation of the handle tightens or loosens the footwear in the midfoot region.

Description

[Technical Field]

[0001] FIELD OF THE DISCLOSURE The present disclosure relates generally to articles of footwear that include a closure mechanism, and more particularly to closures having a twist fastener mechanism. [Background technology]

[0002] Many conventional shoes or other footwear articles generally consist of an upper and a sole attached to the underside of the upper. Conventional shoes also include an interior space—i.e., a void or cavity formed by the upper and the inner surface of the sole—that accommodates the user's foot before the shoe is fastened to the foot. The sole is attached to the underside or boundary of the upper and is positioned between the upper and the ground. As a result, the sole typically provides the user with stability and cushioning while wearing the shoe. In some cases, the sole may include multiple components, such as an outsole, a midsole, and a top. The outsole provides traction to the bottom surface of the sole, while the midsole is attached to the inner surface of the outsole and can provide cushioning or additional stability to the sole. For example, the sole may include specific foam materials that can increase stability at one or more desired locations along the sole or that can reduce stress and impact energy applied to the foot or leg when the user runs, walks, or engages in another activity. The sole may also include additional components, such as an embedded plate, to increase the overall rigidity of the sole and reduce energy loss during use.

[0003] The upper generally extends upward from the sole and defines an interior cavity that completely or partially encases the foot. The upper often extends across the instep and toe areas, medial and lateral surfaces of the foot. Many footwear articles also include a tongue that extends across the instep to fill the gap between the medial and lateral surfaces of the upper, defining an opening to the cavity. The tongue may also be positioned below a lacing system, between the medial and lateral sides of the upper, to allow the shoe's tightness to be adjusted. The tongue may also be manipulated by the user to allow the foot to move in and out of the interior space or cavity. Furthermore, the lacing system allows the user to adjust predetermined dimensions of the upper or sole, allowing the upper to accommodate a wide variety of foot lasts having different sizes and shapes.

[0004] Many shoe uppers can be constructed from a wide variety of materials, which can be used to form the upper and selected for use based on one or more intended uses of the shoe. The upper can also include sections of different materials specialized for specific areas of the upper. For example, it may be desirable to add additional stability to the areas adjacent to the forefoot or heel portion of the upper to provide greater resistance or rigidity. In contrast, other portions of the shoe may include soft woven fabrics to provide properties such as stretch resistance, flexibility, breathability, and moisture wicking. Summary of the Invention [Problem to be solved by the invention]

[0005] However, many people desire footwear with an upper that provides increased comfort and a better fit, along with an improved closure mechanism. One common closure mechanism that tightens the upper and tongue around the user's foot is the use of shoelaces. While shoelaces certainly provide a closure mechanism, shoelaces can break or come undone. Additionally, shoelaces can loosen over time, which can lead to unsightly wear. [Means for solving the problem]

[0006] The articles of footwear described herein can have a variety of configurations. An article of footwear can have an upper and a sole structure connected to the upper.

[0007] In some embodiments, an article of footwear includes an upper and a fastener. The upper is attached to a sole structure. The fastener includes a handle disposed within a first cavity at a heel end of the sole structure. The handle is operably coupled to a cable that extends along the sole structure from the heel region to the midfoot region of the footwear. Rotation of the handle allows for tightening or loosening of the footwear in the midfoot region.

[0008] In some embodiments, an article of footwear includes an upper and a fastener. The upper is attached to a sole structure. The fastener includes a handle disposed at a heel end of the sole structure. A first cable extends from the sole structure to a portion of the upper. The handle is coupled to allow manipulation of the first cable. Rotation of the handle in a first direction is configured to apply tension to the first cable.

[0009] In some embodiments, an article of footwear includes an upper and a fastener. The upper is attached to a sole structure. The fastener includes a handle disposed at a heel end of the sole structure. A first slat extends from the sole structure along the upper. A shaft is coupled to the handle such that the first slat can be manipulated by the handle. The handle and shaft are configured to rotate within the sole structure to adjust the tightness of the footwear. The first slat is configured to translate into the sole structure upon rotation of the shaft.

[0010] In some embodiments, the handle is formed as a cylinder, a square, or a rectangle, and it is contemplated that other configurations may be implemented.

[0011] Other aspects of the article of footwear, particularly its features and advantages, will become apparent to those skilled in the art upon review of the figures and detailed description herein, and all such aspects of the article of footwear are intended to be included in the detailed description and this summary.

[0013] The following description and accompanying drawings disclose various embodiments or configurations of shoes and sole structures. While shoe or sole structure embodiments are disclosed with respect to athletic shoes, such as running shoes, tennis shoes, and basketball shoes, the concepts associated with shoe or sole structure embodiments can be applied to a wide range of footwear and footwear styles, including, for example, cross-training shoes, football shoes, golf shoes, hiking shoes, hiking boots, ski and snowboard boots, soccer shoes and cleats, walking shoes, and track cleats. The shoe or sole structure concepts can also be applied to articles of footwear considered non-athletic, including dress shoes, sandals, loafers, slippers, and heels. In addition to footwear, certain concepts described herein can also be applied to and incorporated into other types of apparel or other athletic equipment, including helmets, padding or protective padding, shin guards, and gloves. Furthermore, certain concepts described herein can be incorporated into cushions, backpack straps, golf clubs, or other consumer or industrial products. Accordingly, the concepts described herein can be utilized in a variety of products.

[0014] As used herein, the term "about" refers to variations in numerical quantities resulting from, for example, typical measuring and manufacturing procedures used for articles of footwear or other manufacture that may include embodiments of the present disclosure, inadvertent errors in these procedures, differences in manufacture, source, or purity of ingredients used to make a composition or mixture or practice a method, etc. Throughout this disclosure, the terms "about" and "approximately" refer to a range of ±5% of the value of the numerical value that follows the term.

[0015] The present disclosure relates to articles of footwear and / or specific components of such articles of footwear, such as uppers and / or soles, or sole structures. Uppers may be constructed of knitted, woven, and / or nonwoven fabrics. Knitted fabrics can be produced by knitting yarns, woven fabrics by weaving yarns, and nonwoven fabrics by producing a monolithic nonwoven web. Knitted fabrics include fabrics formed by warp knitting, weft knitting, flat knitting, circular knitting, and / or other suitable knitting operations. Knitted fabrics may have, for example, plain knit, mesh knit, and / or rib knit constructions. Woven fabrics include woven fabrics with numerous weaves, such as, but not limited to, plain weave, twill weave, satin weave, dobbin weave, jacquard weave, double weave, and / or double weave fabrics. Nonwoven fabrics include, for example, woven fabrics made by airlaid and / or spunlaid processes. The upper can be constructed of different materials, such as first yarns, second yarns, and / or third yarns, which can have different properties or different visual characteristics.

[0016] 1-3 illustrate an exemplary embodiment of footwear 100 including an upper 102 (see FIGS. 1 and 2) and a sole structure 104. Upper 102 is attached to sole structure 104, and together they define an interior cavity 106 (see FIG. 2) into which the foot is inserted. For reference, footwear 100 comprises a forefoot region 108, a midfoot region 110, and a heel region 112. Forefoot region 108 generally corresponds to the portion of footwear 100 that encases portions of the foot, including the toes, ball of the foot, and the joints connecting the metatarsals to the toes or phalanges. Midfoot region 110 is adjacent to and proximal to forefoot region 108 and generally corresponds to the portion of footwear 100 that encases the arch of the foot. Heel region 112 is proximate and adjacent to midfoot region 110 and generally corresponds to the portion of footwear 100 that surrounds the rear of the foot including the calcaneus or heel bone, the ankle, and / or the Achilles tendon.

[0017] Many conventional footwear uppers are formed from multiple elements (e.g., textiles, polymer foams, polymer sheets, leather, synthetic leather) joined together by welding or stitching at seams. In some embodiments, the upper 102 of footwear 100 is formed from a knit fabric or knitted components. In various embodiments, the knitted components can incorporate different types of yarns that impart different properties to the upper. For example, one region of the upper 102 can be formed from a first type of yarn that imparts a first property, while another region of the upper 102 can be formed from a second type of yarn that imparts a second property. This configuration allows the properties of the upper 102 to be varied throughout the upper 102 by selecting specific yarns for different regions of the upper 102.

[0018] 1 and 2, with regard to the material(s) comprising upper 102, it is contemplated that the specific properties that a particular type of yarn imparts to a region of the knit component will depend, at least in part, on the materials forming the various filaments and fibers of the yarn. For example, cotton can impart a soft effect, biodegradability, or a natural aesthetic to the knit material. Stretch polyester and elastic polyester can impart desired stretch and recovery properties to the knit material, respectively. Rayon can provide a shiny, moisture-wicking material, wool can provide enhanced moisture-wicking material, nylon can provide a durable, abrasion-resistant material, and polyester can provide a durable, hydrophobic material.

[0019] Other aspects of the knit component can also be varied to affect its properties and provide desired characteristics. For example, the yarns forming the knit component can include monofilament yarns or multifilament yarns, or the yarns can include filaments, each formed of two or more different materials. Additionally, the knit component can be formed using a particular knitting process to impart specific properties to regions of the knit component. Thus, both the materials forming the yarns and other properties of the yarns can be selected to impart different properties to specific portions of the upper 102.

[0020] Continuing with reference to FIGS. 1 and 2 , in some embodiments, the elasticity of a knit structure may be measured based on a comparison of the width or length of the knit structure in a first, unstretched state to the width or length of the knit structure in a second, stretched state after a lateral force is applied to the knit structure. In further embodiments, upper 102 may also include additional components. For example, in some embodiments, a heel plate or cover (not shown) may be provided in heel region 112 to provide additional support to the user's heel. In some embodiments, other elements, such as plastic materials, logos, trademarks, etc., may also be applied and secured to the exterior surface using adhesives or a thermoforming process. In some embodiments, properties associated with upper 102, such as stitch type, yarn type, or properties associated with different stitch types or yarn types, such as stretch, aesthetic appearance, thickness, breathability, or scuff resistance, may be varied.

[0021] The sole structure 104 is connected to or secured to the upper 102 and extends between the user's foot and the ground when the footwear 100 is worn by the user. The sole structure 104 may include one or more components, which may include an outsole, a midsole, a heel, a panel, and / or an insole. For example, in some embodiments, the sole structure may include an outsole that provides traction to the user and structural integrity to the sole structure, a midsole that provides cushioning, and an insole that supports the user's arch. Furthermore, the insole may be a Strobel board, a forefoot board, a lasting board, or the like, or a combination thereof, and the insole may be provided between the upper 102 and the sole structure 104 or may be provided as part of the upper 102.

[0022] 1 and 2 , an insole can be disposed within the interior cavity of the upper and can be in direct contact with the user's foot while the footwear is being worn. Additionally, the upper can also include a liner (not shown) that can enhance comfort, for example, by reducing friction between the user's foot and the upper, sole, insole, etc., and / or by providing moisture-wicking properties. The liner can cover the entire interior cavity or only a portion of it. In some embodiments, a binding (not shown) can surround the opening of the interior cavity to secure the liner to the upper and / or to provide aesthetic appeal to the article of footwear.

[0023] 2 and 3 , footwear 100 defines a lateral side 114 and a medial side 116. The lateral side 114 corresponds to the portion of footwear 100 that faces outward when a user is wearing the shoe, while the medial side 116 corresponds to the portion of footwear 100 that faces inward. As such, footwear 100 has opposing lateral and medial sides 114, 116. The medial and lateral sides 116 are adjacent to one another along a longitudinal center plane or central axis 118 of footwear 100, which is coplanar with longitudinal axis L in FIG. 1 . As described further herein, the central axis 118 may define a central, medial axis between the medial and lateral sides 116, 114 of footwear 100. Stated another way, the central axis 118 can extend between the rear proximal end 120 of the footwear 100 and the front distal end 122 of the footwear 100 and continuously define the center of the insole 124, sole structure 104 and / or upper 102 of the footwear 100; i.e., the central axis 118 is a linear axis extending from the rear proximal end 120 of the heel region 112 to the front distal end 122 of the forefoot region 108.

[0024] 3 , unless otherwise specified, footwear 100 may be defined by a forefoot region 108, a midfoot region 110, and a heel region 112. The forefoot region 108 may generally correspond to the portion of footwear 100 that encases a portion of a foot 126, including a set of toes or phalanges 128, a ball of the foot 130, and a set of joints 132 that connect a set of metatarsals 134 of the foot 126 to the set of toes or phalanges 128. The midfoot region 110 is proximate to and adjacent to the forefoot region 108. The midfoot region 110 generally corresponds to the portion of footwear 100 that encases an arch 136 of the foot 126 along with a bridge 138 of the foot 126. The heel region 112 is proximate to and adjacent to the midfoot region 110. Heel region 112 generally corresponds to the portion of footwear 100 that encases the rear portion of foot 126, including the heel or calcaneus 140, the ankle (not shown), and / or the Achilles tendon (not shown).

[0025] 1 and 2, forefoot region 108, midfoot region 110, heel region 112, medial surface 116, and lateral surface 114 are intended to define boundaries or regions of footwear 100. To this end, forefoot region 108, midfoot region 110, heel region 112, medial surface 116, and lateral surface 114 may generally characterize portions of footwear 100. In certain aspects of the present disclosure, this may refer to portions or elements coextensive with one or more of forefoot region 108, midfoot region 110, heel region 112, medial surface 116, and / or lateral surface 114. Additionally, both upper 102 and sole structure 104 may be characterized as having portions along forefoot region 108, midfoot region 110, heel region 112, and / or medial surface 116 and / or lateral surface 114. Thus, the upper 102 and sole structure 104, and / or individual portions of the upper 102 and sole structure 104, may include portions located in the forefoot region 108, the midfoot region 110, the heel region 112, and / or along the medial surface 116 and / or the lateral surface 114.

[0026] 2 and 3, the forefoot region 108, midfoot region 110, heel region 112, medial side surface 116, and lateral side surface 114 are shown in detail. The forefoot region 108 extends from a toe tip 142 to a widest portion 144 of the footwear 100. The widest portion 144 is defined or measured along a first line 146 perpendicular to the central axis 118 that extends from a distal portion of the toe tip 142 to a distal portion of the heel tip 148 opposite the toe tip 142. The midfoot region 110 extends from the widest portion 144 to a narrowest portion 150 of the footwear 100. The narrowest portion 150 of the footwear 100 is defined as the narrowest portion of the footwear 100 measured across a second line 152 perpendicular to the central axis 118. Heel region 112 extends from narrowest portion 150 to heel end 148 of footwear 100 .

[0027] It should be understood that many variations will be apparent to those skilled in the art from the foregoing description and its individual components, and that the individual components may be incorporated into many articles of footwear. Accordingly, portions of footwear 100 and its components may be described with reference to general areas or portions of footwear 100, with the understanding that the boundaries of forefoot region 108, midfoot region 110, heel region 112, medial surface 116, and / or lateral surface 114, as described herein, may vary from article to article of footwear. However, the characteristics of footwear 100 and its individual components may also be described with reference to precise areas or portions of footwear 100, and the claims appended hereto may include limitations related to these boundaries of forefoot region 108, midfoot region 110, heel region 112, medial surface 116, and / or lateral surface 114.

[0028] 2 and 3 , medial surface 116 begins at distal toe tip 142 and arcs outward along the medial side of footwear 100, along forefoot region 108, and toward midfoot region 110. Medial surface 116 reaches a first line 146, at which point medial surface 116 curves inward toward a central axis 118. Medial surface 116 extends from first line 146, or widest portion 144, to a second line 152, or narrowest portion 150, at which point medial surface 116 enters midfoot region 110, i.e., crosses first line 146. Upon reaching second line 152, medial surface 116 curves outward, away from central axis 118, at which point medial surface 116 extends into heel region 112, i.e., crosses second line 152. The medial surface 116 then curves outward and then inward to the heel end 148 , terminating at the point where the medial surface 116 intersects with the central axis 118 .

[0029] The lateral surface 114 also arcs outwardly, beginning at the distal toe tip 142, along the forefoot region 108, and along the lateral side of the footwear 100 toward the midfoot region 110. The lateral surface 114 reaches a first line 146, at which point the lateral surface 114 arcs inward toward a central axis 118. The lateral surface 114 extends from the first line 146, i.e., widest portion 144, to a second line 152, i.e., narrowest portion 150, at which point the lateral surface 114 enters the midfoot region 110, i.e., crosses the first line 146. Upon reaching the second line 152, the lateral surface 114 arcs outwardly, away from the central axis 118, at which point the lateral surface 114 extends into the heel region 112, i.e., crosses the second line 152. The lateral surface 114 curves outward and then inward toward the heel end 148 , terminating at the point where the lateral surface 114 intersects with the central axis 118 .

[0030] 2 , upper 102 extends along lateral side 114 and medial side 116 and across forefoot region 108, midfoot region 110, and heel region 112 to encase and wrap a user's foot. When fully assembled, upper 102 includes medial surface 154 and lateral surface 156. Medial surface 154 faces inward and generally defines interior cavity 106, while lateral surface 156 of upper 102 faces outward and generally defines the perimeter or boundary of upper 102. Upper 102 also includes opening 158 located at least partially in heel region 112 of footwear 100, which provides access to interior cavity 106 and allows for foot entry and exit through the opening. In some embodiments, upper 102 may include an instep region 160 that extends from opening 158 in heel region 112 through a region corresponding to the instep of the foot to a region adjacent to forefoot region 108. Instep region 160 may constitute a region similar to the region in which tongue 162 of the present embodiment is located. In some embodiments, upper 102 does not include tongue 162, i.e., upper 102 is tongueless.

[0031] Referring to FIG. 1 , sole structure 104 includes a midsole 164 and an outsole 166. Outsole 166 can define a bottom edge or bottom surface 168 of sole structure 104 across heel region 112, midfoot region 110, and forefoot region 108. Furthermore, outsole 166 can be the ground-contacting portion of sole structure 104 or can include the ground-contacting surface, and can be opposite its insole. As shown in FIG. 1 , bottom surface 168 of outsole 166 can include a tread pattern 170, which can have a variety of shapes and configurations. Outsole 166 can be formed from one or more materials to impart durability, abrasion resistance, wear resistance, or traction to sole structure 104. In some embodiments, outsole 166 can be formed from any type of elastomeric material, such as rubber, including thermoset elastomers or thermoplastic elastomers, or a thermoplastic material, such as thermoplastic polyurethane (TPU). In some embodiments, the outsole 166 can have a hardness up to Shore A 95. Additionally, the outsole 166 can be manufactured by processes including injection molding, vulcanization, layer-by-layer printing, additive manufacturing systems or methods, and the like.

[0032] The midsole 164 can be individually constructed from a thermoplastic material, such as polyurethane (PU), and / or ethylene vinyl acetate (EVA), its copolymers, or similar types of materials. In other embodiments, the midsole 164 can be an EVA solid sponge (“ESS”) material, EVA foam (e.g., PUMA® ProFoam Lite™, IGNITE foam), polyurethane, polyether, olefin block copolymer, organosheet, thermoplastic material (e.g., thermoplastic polyurethane, thermoplastic elastomer, thermoplastic polyolefin, etc.), or supercritical foam. The midsole 164 can be a single polymer material or a blend of materials, such as EVA copolymer, thermoplastic polyurethane, polyether block amide (PEBA) copolymer, and / or olefin block copolymer. An example of a polyether block amide (PEBA) material is PEBAX®. In some embodiments, the midsole 164 can be manufactured by processes including injection molding, vulcanization, layer-by-layer printing, or additive manufacturing systems or methods.

[0033] 1 , in embodiments in which the midsole 164 is formed from a supercritical foaming process, the supercritical foam may comprise a microporous or particulate foam of thermoplastic polyurethane (TPU), ethylene vinyl acetate (EVA), PEBAX®, or a mixture thereof, such as a microporous or particulate foam produced by a process carried out in an autoclave, an injection molding apparatus, or a sufficiently heated / pressurized vessel capable of mixing a supercritical fluid (e.g., CO , N , or a mixture thereof) with a preferably molten material (e.g., thermoplastic polyurethane (TPU), ethylene vinyl acetate (EVA), a polyolefin elastomer, or a mixture thereof). In an exemplary process, a solution of the supercritical fluid and molten material is pumped into a pressurized vessel, and then the pressure in the vessel is released, allowing the molecules of the supercritical fluid to rapidly convert to a gas, forming small pockets within the material, causing the material to foam. In further embodiments, the midsole 164 may be formed using alternative methods known in the art, including an expansion press, an injection molding machine, a pellet expansion process, a cold foam process, a compression molding technique, die cutting, or any combination thereof. For example, the midsole 164 may be formed using a process that includes an initial foaming step in which a material is expanded using a supercritical gas, and then compression molded or die cut into a particular shape.

[0034] 4 , one embodiment of footwear 200 includes a first fastener system 204 for tightening or loosening footwear 200 around a user's foot. In the illustrated embodiment, footwear 200 includes an upper 208, a midsole 212, an outsole 166, a forefoot region 108, a midfoot region 110, a heel region 112, a lateral surface 114, and an interior cavity 106. Footwear 200 further includes a panel 216 with a plurality of eyelets 220. First fastener system 204 includes a plurality of cables 224 extending from the plurality of eyelets 220 to a plurality of first openings 228 located on a first or upper surface 232 of midsole 212. Cables 224 may be secured by, for example, adhesive, crimping, forming a knot at each end of each of cables 224, interference fitting, welding, overmolding, or the like. When the plurality of cables 224 are under tension, the downward force 236 applied as a result of operating the first fastening system 204 causes the panel 216 to be pressed down against the upper 208, as shown in FIG.

[0035] 5, the first fastener system 204 includes a first fastener mechanism 240 that utilizes a cable twist fastener 244. In the illustrated embodiment, the cable twist fastener 244 includes a winding assembly 248, a braided shaft 252, and a plurality of cables 224 adapted to apply a downward force 236 to the panel 216 shown in FIG. 4. Additionally, the midsole 212 includes a second body 256 that forms a portion of the heel end 148 and has a second or heel surface 260 facing outwardly therefrom. The heel surface 260 is located in the heel region 112 and includes a third or concave surface 264 located at the heel end 148, as shown in FIG. 5. The concave surface 264 has a first side wall 268 and a first bottom wall 272 that defines the shape of a first cavity 276. The first cavity 276 is in fluid communication with a first passage 280 that extends longitudinally along the midsole 212. The midsole 212 has a first depth 284, indicated by an arrow in FIG. 5 for illustrative purposes. The first depth 284 of the midsole 212 is the length from the upper surface 232 of the midsole 212 to the upper edge. The first depth 284 of the midsole 212 increases toward the heel region 112, extending entirely through the midsole 212 in the heel region 112 as the first passage 280 extends to the concave surface 264. The first passage 280 defines a second opening 288 that intersects a first axis 292 that extends from the heel region 112 to the forefoot region 108. In some embodiments, the first axis 292 intersects the central axis 118 (see FIG. 2). In some embodiments, the first axis 292 is laterally offset from and does not intersect the central axis 118 (see FIG. 2).

[0036] The handle 500 has a third body 504, an actuator mechanism 508 provided as a plurality of grips 512 projecting from a fourth or outer handle surface 516, and a fifth or circumferential handle surface 520 surrounding and projecting perpendicularly from the outer handle surface 516. In some embodiments, the handle 500 is configured to fit into the first cavity 276. The plurality of grips 512 can be grasped by a user to facilitate rotating 524 the handle 500 about the first axis 292, for example, clockwise or counterclockwise.

[0037] 6 , the upper surface 232 of the midsole 212 includes a sixth surface or cutout surface 296. The cutout surface 296 can be formed in the upper surface 232 by removing (e.g., cutting) material from the midsole 212 during molding of the midsole 212 or after molding of the midsole 212. The cutout surface 296 includes a plurality of first lateral channels 300 that extend from a second or longitudinal channel 304 that is centrally located along or proximate to the first axis 292. In some embodiments, the plurality of lateral channels 300 extend perpendicular to the first axis 292. In some embodiments, at least one channel of the plurality of lateral channels 300 extends at an acute angle relative to the first axis 292. In some embodiments, each of the plurality of lateral channels 300 extending to the medial surface 116 of the midsole 212 is offset along the first axis 292 with respect to each of the plurality of lateral channels 300 extending to the lateral surface 114 of the midsole 212. That is, the plurality of lateral channels 300 extending from the longitudinal channel 304 to the medial surface 116 of the midsole 212 are not aligned along the first axis 292 with the plurality of lateral channels 300 extending from the longitudinal channel 304 to the lateral surface 114 of the midsole 212. In some embodiments, each of the plurality of lateral channels 300 extending from the longitudinal channel 304 to the medial surface 116 of the midsole 212 is aligned along the first axis 292 with one of the plurality of lateral channels 300 extending from the longitudinal channel 304 to the lateral surface 114 of the midsole 212.

[0038] The longitudinal channel 304 formed in the cutout surface 296 further includes a rear channel 308 extending rearward of the first passageway 280 along the first axis 292. The upper surface 232 of the midsole 212 slopes downward in the longitudinal direction from the heel region 112 toward the forefoot region 108, for example, toward the outsole 166 (see FIG. 4 ). The rear channel 308 in the upper surface 232 (i.e., top surface) of the midsole 212 transitions into and communicates with the first passageway 280 that extends through or within the midsole 212. An enclosure 312 is provided as part of the second body 256 of the midsole 212. In the illustrated embodiment, the enclosure 312 surrounds the first passageway 280 and includes an upper member 316 that is convexly curved relative to the outsole 166 (see FIG. 2 ) and extends vertically above the upper surface 232. In some embodiments, the plurality of lateral channels 300 have a second depth 320 and the longitudinal channel 304 has a third depth 324, where the second depth 320 and the third depth 324 are directionally the same as the first depth 284 shown in FIG. 5 . In some embodiments, the third depth 324 is greater, i.e., deeper, than the second depth 320. The longitudinal channel 304 is configured to accommodate the winding assembly 248 (see FIG. 5 ), the plurality of lateral channels 300 are configured to accommodate each of the plurality of cables 224 (see FIG. 5 ), and the rear channel 308 is configured to accommodate the braided shaft 252 (see FIG. 5 ). In some embodiments, the longitudinal channel 304 has a pair of receptacles 328 and an intermediate channel 332 extending therebetween. The first axis 292 extends along the centerline of the set of receptacles 328 , the at least one intermediate channel 332 , the rear channel 308 , and the first passageway 280 .

[0039] 7, the cable twist fastener 244 includes a winding assembly 248, a braided shaft 252, and a plurality of cables 224. In some embodiments, the winding assembly 248 includes a set of cores 336 and an intermediate portion 340. The set of cores 336 has a first diameter 344 that is wider than a second diameter 348 of the intermediate portion 340. The braided shaft 252 includes a first shaft 352 and a plurality of braided wires 356 configured to extend from the winding assembly 248 along a second axis 360. After insertion into the first passage 280 (see FIGS. 5 and 6), the plurality of braided wires 356 are secured to the handle 500 by, for example, adhesives, crimping, knotting the ends of the plurality of braided wires 356, an interference fit, welding, overmolding, or the like. In some embodiments, the first shaft 352 and the set of cores 336 of the winding assembly 248 are solid bodies without any cavities or voids therein. In some embodiments, the first shaft 352, the winding assembly 248, or both have cavities or voids therein. In some embodiments, the set of cores 336 are hollow, allowing for the removal and storage of the plurality of cables 224. In some embodiments, the plurality of cables 224 are secured to the winding assembly 248 by, for example, adhesive, crimping, knotting at each end of the plurality of cables 224, interference fitting, welding, overmolding, etc.

[0040] Each of the plurality of cables 224 has a length 364 and can be made of a natural material, a plastic material, metal wire, a combination of metal wire and plastic overmolding, or other combinations thereof. The length 364 of each of the plurality of cables 224 can be measured from the far end or distal end 368 of each of the plurality of cables 224 to the respective core 336. Due at least in part to the materials used, each of the plurality of cables 224 has sufficient strength to hold sufficient tension to apply a downward force 236 to the panel 216 without breaking (see FIG. 4). Furthermore, each of the plurality of cables 224 has sufficient flexibility to be positioned within the plurality of lateral channels 300 (see FIG. 6), bend along the medial surface 116 or the lateral surface 114 of the footwear 200 (see FIG. 4), be secured to one of the plurality of eyelets 220 (see FIG. 4), and be configured to wrap around or within the winding assembly 248 as the braided shaft 252 rotates about the second axis 360. After the plurality of braided wires 356 are attached to the handle 500, rotation 524 of the handle 500 (see FIG. 5) rotates the plurality of braided wires 356 either clockwise or counterclockwise. As the rotation 524 of the handle 500 continues (see FIG. 5), the plurality of braided wires 356 twists about the second axis 360 sufficiently to begin transmitting the rotation 524 to the winding assembly 248. As the winding assembly 248 begins to rotate about the second axis 360, the plurality of cables 224 are wound around the first diameter 344 or the second diameter 348 of the winding assembly 248. In this manner, operation of the first fastening system 204 can reduce the length 364 of each of the plurality of cables 224. This reduction in the length 364 of the plurality of cables 224 creates tension in each of the plurality of cables 224, which can apply a downward force 236 to the panel 216 (see FIG. 4).

[0041] 6 and 7, the cable twist fastener 244 (FIG. 7) is configured so that each of the plurality of cables 224 (FIG. 7) fits within one of the plurality of transverse channels 300 (FIG. 6), the braided shaft 252 (FIG. 7) fits within the rear channel 308, and the first passage 280 (FIG. 6) and winding assembly 248 (FIG. 7) fit within the receptacle 328 of the longitudinal channel 304 (FIG. 6). Furthermore, when the cable twist fastener 244 (FIG. 7) is inserted onto the cutout surface 296 (FIG. 6), the first axis 292 (FIG. 6) and the second axis 360 (FIG. 7) are aligned. In some embodiments, after the cable twist fastener 244 (FIG. 7) is inserted onto the cutout surface 296 (FIG. 6), the plurality of cables 224 (FIG. 7) are secured to the plurality of eyelets 220 (see FIG. 4), and the plurality of braided wires 356 (FIG. 7) are secured to the handle 500 (see FIG. 5), the insole 124 can be positioned over the upper surface 232 such that the cutout surface 296 (FIG. 6) and the cable twist fastener 244 (FIG. 7) are covered and cushioned for the user's foot.

[0042] Referring to FIG. 8 , second fastening mechanism 372 uses a rigid twist fastener 376 having a rigid shaft 380, multiple cables 224, and a housing 384. Rigid twist fastener 376 may be received within and / or inserted onto cutout surface 296 of midsole 212 shown in FIG. 6 . Housing 384 has a first outer surface 388 and is comprised of a midsection 392 and a rear section 396. Midsection 392 includes a plurality of openings 400 disposed laterally and facing medial and lateral surfaces 116, 114 of footwear 200 (similar to FIG. 6 ). A third axis 404 extends along the centerline of rigid shaft 380 and housing 384. In some embodiments, third axis 404 intersects central axis 118 when assembled. In some embodiments, third axis 404 does not intersect central axis 118 when assembled. The housing 384 defines an internal cavity 408 in which the rigid shaft 380 is disposed. In some embodiments, the intermediate portion 392 includes a pair of cores 412 and at least one connecting member 416. The rear portion 396 extends from the intermediate portion 392 along the third axis 404 toward the handle 500. In some embodiments, the rear portion 396 includes a flange 420. The presence of the flange 420 can provide additional stability for attaching, retaining, and rotating the rigid twist fastener 376 to the notched surface 296.

[0043] The rigid shaft 380 is rotatably secured to a first end 424 of the intermediate portion 392 located in the internal cavity 408 opposite or remote from the first rear portion 396. In some embodiments, the rigid shaft 380 is configured to be secured to the handle 500 after insertion through the first passageway 280. The rigid shaft 380 can be secured to the handle 500 by various means, including adhesive, crimping, an interference fit, a bayonet lock, welding, or overmolding. The plurality of cables 224 can be secured to the rigid shaft 380 by, for example, adhesive, crimping, an interference fit, tying, welding, or overmolding. In some embodiments, the plurality of second openings 400 in the inner surface 116 of the housing 384 are offset from any of the plurality of second openings 400 in the outer surface 114 of the housing 384 along the third axis 404. That is, each of the plurality of second openings 400 is staggered with respect to third axis 404. In some embodiments, each of the plurality of second openings 400 is perpendicular to third axis 404. Each of the plurality of cables 224 is secured to rigid shaft 380 and extends through a respective one of the plurality of second openings 400. Each of the plurality of cables 224 is inserted into the plurality of lateral channels 300 and extends through the plurality of first openings 228. Each of the plurality of cables 224 extends onto medial surface 116 or lateral surface 114 of footwear 200 to be secured to the plurality of eyelets 220 of panel 216.

[0044] Continuing with reference to FIG. 8 , rotation 524 of handle 500 (see FIG. 5 ) rotates rigid shaft 380, which is rotatably coupled to first end 424 of intermediate section 392. Rotation 524 (see FIG. 5 ) of rigid shaft 380, either clockwise or counterclockwise, causes each of the plurality of cables 224 to wrap around rigid shaft 380, forming a coil 428 with each set of cores 412. Coils 428 increase or decrease in size, i.e., diameter and / or length, in response to rotation 524 of rigid shaft 380. This results in extension 432 or contraction 436 of each of the plurality of cables 224, which translates into a downward force 236 against panel 216 (see FIG. 4 ). In some embodiments, downward force 237 increases or decreases in proportion to the size of the coil. In some embodiments, each coil 428 does not contact another coil 428.

[0045] Referring to FIG. 9, a second embodiment of footwear 700 includes a second fastening system 704 that shares similar function and structure with footwear 200 of FIG. 4, with similar reference numerals being used to indicate similar elements. Footwear 700 includes an upper 708, a midsole 712, an outsole 166, a forefoot region 108, a midfoot region 110, a heel region 112, a lateral surface 114, and an interior cavity 106. Footwear 700 further includes a panel 216 that includes a plurality of eyelets 220. A plurality of slats 716 extend through and are secured to each of the plurality of eyelets 220. Each of the plurality of slats 716 extends from a plurality of second openings 400 located on an upper surface 232 of the midsole 712. Each of the plurality of slats 716 is slat-shaped, i.e., each of the plurality of slats 716 is flat and wide compared to the plurality of cables 224 of FIG. 4. The plurality of slats 716 can be secured to each of the plurality of eyelets 220 by various means, including adhesive, crimping, interference fitting, welding, or overmolding. The plurality of slats 716 are configured to bend or flex as they transition from the plurality of second openings 400 to the plurality of eyelets 220. When the plurality of slats 716 are under tension, the panel 216 is forced down onto the upper 708 by a downward force 236.

[0046] 10 , the third fastening mechanism 720 uses a slat twist fastener 724 having a fifth body or core 728, a rear shaft 732, and a plurality of slats 716 protruding from a seventh or outer surface 736 of the core 728. In some embodiments, a first protrusion 740 extends from the outer surface 736 of the core 728. A fourth axis 744 extends through the first protrusion 740 (if present), the core 728, and the rear shaft 732. The rear shaft 732 is configured to be secured to the handle 500 by, for example, adhesive, crimping, an interference fit, welding, or overmolding. Rotation 524 of the handle 500 causes rotation 524 of the rear shaft 732 and the core 728. As the core 728 rotates, each of the plurality of slats 716 winds onto or unwinds from the core 728, thereby increasing or decreasing the length 364 of each of the plurality of slats 716. When the plurality of slats 716 are under tension, the panel 216 is forced down onto the upper 708 by a downward force 236 (see FIG. 9).

[0047] 11 , the midsole 712 is similar to the midsole 212 shown in FIG. 6 , and therefore, like reference numerals are used to indicate like elements. The upper surface 232 of the midsole 712 is further defined by a cutout surface 296. The cutout surface 296 may be formed in the upper surface 232 during molding of the midsole 712 or by removing material (e.g., notching) from the midsole 712 after molding of the midsole 712. The cutout surface 296 includes a plurality of second or lateral channels 748 that extend from the longitudinal channel 750 toward the medial surface 116 and the lateral surface 114 of the midsole 712. In some embodiments, the lateral channels 748 extend perpendicular to the first axis 292. Each of the lateral channels 748 is wider than the lateral channels 300 (see FIG. 6 ) to accommodate the width of each of the slats 716. In some embodiments, each of the plurality of lateral channels 748 extending from the longitudinal channel 750 to the medial surface 116 of the midsole 712 is offset along the first axis 292 relative to each of the plurality of lateral channels 748 extending from the longitudinal channel 750 to the lateral surface 114 of the midsole 712. That is, the plurality of lateral channels 748 extending to the medial surface 116 of the midsole 712 are not aligned with the plurality of lateral channels 748 extending to the lateral surface 114 of the midsole 712 along the first axis 292. In some embodiments, the plurality of lateral channels 748 are configured to accommodate the plurality of slats 716 (see FIG. 10 ). In some embodiments, each of the plurality of lateral channels 748 extending from the longitudinal channel 750 to the medial surface 116 of the midsole 712 is aligned with one of the plurality of lateral channels 748 extending from the longitudinal channel 750 to the lateral surface 114 of the midsole 712 along the first axis 292.

[0048] 5. The cutout surface 296 further includes a rear channel 308 that extends along the first axis 292 from the longitudinal channel 750 to the first passageway 280. The rear channel 308, which is above the upper surface 232 of the midsole 712, transitions into the first passageway 280, which is within the midsole 712 (i.e., not already above the upper surface 232 of the midsole 712). The midsole 712 includes an enclosure 312 and an upper member 316 that extends above the upper surface 232. In some embodiments, the plurality of lateral channels 748 have a fourth depth 752 and the longitudinal channel has a fifth depth 756, which are directionally identical to the first depth 284 of FIG. 5. In some embodiments, the fifth depth 756 is greater, i.e., deeper, than the fourth depth 752. The longitudinal channel 750 is configured to hold the core 728 (see FIG. 10 ), the plurality of transverse channels 748 are configured to hold each of the plurality of slats 716 (see FIG. 10 ), and the rear channel 308 and first passageway 280 are configured to hold the rear shaft 732 (see FIG. 10 ). In some embodiments, the longitudinal channel 750 has a receptacle 758 and a distal end 759. The first axis 292 extends along the centerlines of the receptacle 758, the distal end 759, the rear channel 308, and the first passageway 280. In some embodiments, the distal end 759 is configured to hold the first protrusion 740 (see FIG. 10 ), and the receptacle 758 is configured to hold the core 728 (see FIG. 10 ).

[0049] 12, the handle 500 includes a plurality of grips 512 and a release mechanism 528 utilizing a toggle 532 that protrudes from the outer handle surface 516. The toggle 532 is positioned and angled within a toggle or third opening 536. A lock slot 540 that contacts the circumferential handle surface 520 defines a fourth opening 544 that protrudes from the circumferential handle surface 520. The toggle 532 is configured to rotate, e.g., angle, toward and away from the lock slot 540. In some embodiments, the plurality of grips 512 protrude farther from the outer handle surface 516 than the toggle 532. In some embodiments, the plurality of grips 512 and the toggle 532 protrude the same amount from the outer handle surface 516. In some embodiments, the circumferential handle surface 520 is configured as a circumferential sidewall that facilitates rotation 524 of the handle 500 inside the first cavity 276 (see FIG. 5).

[0050] 13 , the handle 500 has a fifth axis 548 that intersects the centerlines of the third opening 536, the locking slot 540, and the locking channel 552 connecting the locking slot 540 to the third opening 536. In some embodiments, the plurality of grips 512 are oriented parallel to the fifth axis 548. In some embodiments, at least one of the plurality of grips 512 is oriented at an acute angle relative to the fifth axis 548. A first stop 556 and a second stop 560 are disposed on an eighth or channel surface 564 of the locking channel 552. The channel surface 564 defines a bolt or second path 568. The first stop 556 is closer to the locking slot 540 than the second stop 560, and the second stop 560 is closer to the third opening 536 than the first stop 556. The first edge 572 defines the shape of the third opening 536 and may have a chamfered shape.

[0051] 14-16, which show a cross-sectional view of the handle 500, the third opening 536 defines a third path 576 between the outer handle surface 516 of the handle 500 and a channel surface 564 of the lock channel 552. The channel surface 564 includes a ninth or rear surface 580, which is the surface of the lock channel 552 farthest from the lock slot 540. Referring to FIGS. 15 and 16, the lock bolt 584 has a lock shaft 588 configured to fit within the lock channel 552. The lock shaft 588 has a sixth body 592. The sixth body 592 includes a stopper or first retainer 596, a toggle or second retainer 600, a lock or second end 604, and a recess or third end 608. The first retainer 596 is configured to selectively engage with the first stopper 556 or the second stopper 560 to create a stable position for the locking bolt 584 when the first retainer 596 is engaged with the first stopper 556 or the second stopper 560, and to create an unstable position for the locking bolt 584 when the first retainer 596 is not engaged with either the first stopper 556 or the second stopper 560. In this manner, the handle 500 can provide a bistable positioning system.

[0052] 15 and 16 , the second retainer 600 is configured to pivotally retain the toggle or fourth end 612 of the toggle 532. When the second retainer 600 of the locking bolt 584 and the fourth end 612 of the toggle 532 are pivotally coupled, the toggle 532 has a forward slope 616 toward the locking slot 540 (see FIG. 16 ) and a rearward slope 620 away from the locking slot 540 (see FIG. 15 ). The forward slope 616 and the rearward slope 620 are defined throughout the longitudinal extent of the toggle 532 and form angles with respect to the fifth axis 548. In some embodiments, the forward slope 616 is equal to but opposite in direction to the rearward slope 620 with respect to the fifth axis 548. In some embodiments, the forward slope 616 and the rearward slope 620 are disposed at different angles relative to each other, apart from being opposite in direction. In some embodiments, the forward ramp 616 and the rear ramp 620 are not inverse to one another; instead, the forward ramp 616 and the rear ramp 620 are simply positioned at different angles relative to one another, and articulating the toggle 532 between or among different angular positions relative to the fifth axis 548 provides different functions or operations. The second end 604 is configured to selectively retract within the second path 568 in a retracted or unlocked configuration 624 (see FIG. 16 ) and to extend beyond the second path 568 in an extended or locked configuration 628 (see FIG. 15 ). The third end 608 is configured to selectively move toward the rear surface 580 in the unlocked configuration 624 (see FIG. 16 ) and away from the rear surface 580 in the locked configuration 628 (see FIG. 15 ).

[0053] 15 and 16, when the lock bolt 584 is in the unlocked configuration 624 (see FIG. 16), the first retainer 596 engages with the second stopper 560, the second retainer 600 is closer to the third end 608 than when the lock bolt 584 is in the locked configuration 628 (see FIG. 15), the second end 604 is closer to the third end 608 than when the lock bolt 584 is in the locked configuration 628 (see FIG. 15), and the toggle 532 is positioned in a forward tilt 616 toward the lock slot 540. When the lock bolt 584 is in the locked configuration 628 (see FIG. 15 ), the first retainer 596 engages with the first stopper 556, the second retainer 600 is farther from the third end 608 than when the lock bolt 584 is in the unlocked configuration 624 (see FIG. 16 ), the second end 604 is farther from the third end 608 than when the lock bolt 584 is in the unlocked configuration 624, and the toggle 532 has a rearward tilt 620 state away from the lock slot 540.

[0054] 5 and 15, the second end 604 of the locking bolt 584 extends outside the second path 568 (see FIG. 15). The second end 604 is configured to engage the first sidewall 268 of the recess 264 (see FIG. 5). When the locking bolt 584 is in the locked configuration 628 (see FIG. 15), the second end 604 contacts the first sidewall 268, allowing a desired amount of tension in the cable twist fastener 244, the hard twist fastener 376, or the slat twist fastener 724 to be selected and maintained. The first stop 556 engages the first retainer 596 to ensure that the second end 604 remains engaged with the first sidewall 268. Referring to FIG. 16 , if a user wishes to change the tension, such as to remove footwear 200, 700 or tighten panel 216, the user simply flips toggle 532 to a second, stable, bistable position, which is unlocked configuration 624 (see FIG. 16 ). Toggle 532 is flipped by overcoming the strength of engagement between first retainer 596 and first stopper 556. Flipping toggle 532 applies a forward tilt 616 to toggle 532, transitioning locking bolt 584 to unlocked configuration 624 (see FIG. 16 ). Applying forward tilt 616 to toggle 532 induces first retainer 596 to engage second stopper 560. Referring to FIG. 16, when the second end 604 is in the unlocked configuration 624, the first side wall 268 (see FIG. 5) is not engaged and the downward force 236 on the panel 216 (see FIG. 4) can be adjusted to make it easier to remove the footwear 200, 700 with a device that does not require shoelaces.
