[0005] SEQUENCE LISTING

[0006] NOT APPLICABLE TECHNICAL FIELD

[0007] The present disclosure relates generally to an article of footwear, and more particularly to an article of footwear having a fastening mechanism including a tensioning member and one or more tensioning elements. BACKGROUND

[0008] Many conventional shoes or other articles of footwear generally include an upper and a sole attached to a lower end of the upper. Conventional shoes also include an interior space, i.e., a void or cavity, formed by interior surfaces of the upper and the sole that accommodates a user’s foot prior to securing the shoe to the foot. The sole is attached to a lower surface or border of the upper and is positioned between the upper and the ground. As a result, the sole generally provides stability and cushioning to the user when the shoe is being worn. In some cases, the sole can include multiple components, such as an outsole, a midsole, and a top. The outsole can provide traction to a bottom surface of the sole, the midsole can be attached to an interior surface of the outsole, and can provide cushioning or increased stability to the sole. For example, the sole can include a particular foam material that can increase stability at one or more desired locations along the sole, or a foam material that can reduce stress or impact energy on the foot or leg when the user is running, walking, or engaged in other activities. The sole can also include additional components, such as plates, embedded in the sole to increase the overall stiffness of the sole and reduce energy loss during use.

[0009] The upper generally extends upward from the sole and defines an interior void that fully or partially encloses a foot. In most cases, the upper extends over the instep and toe areas and around the medial and lateral sides of the instep and toe areas. Many articles of footwear can also include a tongue that extends across the instep area to bridge a gap between the medial and lateral edges of the upper that defines an opening into the void. The tongue can also be disposed under a lacing system and between the medial and lateral sides of the upper to allow for adjustment of the tightness of the shoe. The tongue can also be manipulated by the user to allow ingress and egress of the foot from the interior void or space. Additionally, fastening mechanisms can allow the user to adjust certain dimensions of the upper or sole, thereby allowing the upper to accommodate various foot shapes having different dimensions and shapes.

[0010] The upper of many shoes can include a variety of materials that can be used to form the upper and selected for use according to one or more intended uses of the shoe. The upper can also include portions that include different materials specific to certain areas of the upper. For example, increased stability can be required in the forefoot or adjacent heel areas of the upper to provide a higher degree of resistance or rigidity. Conversely, other portions of the shoe can include soft textile fabrics to provide areas with stretch resistance, flexibility, breathability, or sweat wicking properties.

[0011] While many currently available articles of footwear have different features related to the characteristics described above, in many cases, there is a need for footwear having fastening mechanisms that are more easily tightened and loosened by the user, as well as improved support for a user’s foot along the upper of the footwear.

[0041] 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 variety of footwear and footwear styles, including, for example, cross-training shoes, football shoes, golf shoes, hiking boots, ski and snowboard boots, soccer shoes, and slip-resistant shoes, walking shoes, and tracked slip-resistant shoes. The concepts of shoe or sole constructions can also be applied to footwear articles considered non-athletic, including dress shoes, sandals, casual shoes, slippers, and high heels. In addition to footwear, the specific concepts described herein can also be applied to and incorporated into other types of clothing or other sporting 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.

[0042] As used herein, the term“about” refers to a possible variation, for example, in a value occurring from typical measuring and manufacturing procedures for an article of footwear or other manufactured article that can include embodiments disclosed herein; from inadvertent error in said procedures; from differences in the manufacturing, sourcing, or purity of ingredients used in the manufacture of compositions or mixtures or in the practice of a method; or the like. Throughout the disclosure, the terms“about” and“approximately” refer to a range of ±5% of a numerical value that precedes the term.

[0043] As used herein, the term“elastic” refers to the elastic or rubber-like properties of a material (e.g., a polymer). For example, a reference to an“elastic material” is intended to denote a material configured to elastically deform when a load is applied to the material and to recover its original shape when the load is removed from the material.

[0044] As used herein, the term“diameter” refers to the shortest distance between opposite sides of a perimeter or opening through a center of the perimeter or opening. Thus, a reference to a“diameter” of a structure herein does not imply that the perimeter or opening of the component in question is generally circular in shape. For example, a reference to a“diameter” of an opening of a component having a non-circular shape can refer to the shortest distance between opposite sides of the opening through a center of the opening. Further, for example, a reference to a“diameter” of an elastically deformable component can refer to a“first diameter” corresponding to a non-elastically deformed circular shape of an opening of the component and a“second diameter” corresponding to an elastically deformed non-circular shape of the opening of the component. Further, for example, a reference to a“diameter” of an elastically deformable component can refer to a“first diameter” corresponding to a non-elastically deformed non-circular shape of an opening of the component having a first shortest distance through a center of the opening between first opposite sides of the opening, and can further refer to a“second diameter” and / or a“third diameter” corresponding to an elastically deformed non-circular shape of the opening of the component having a second and / or third shortest distance through the center of the opening between second and / or third opposite sides of the opening that are different from the first opposite sides.

[0045] Further, as used herein, directional terms are used for ease of discussing certain examples or aspects of the figures unless otherwise defined or limited. For example, references to "downward" or other directions, or "lower" or other positions, can be used in discussing various aspects of a particular example or figure, but do not necessarily require similar orientations or geometries in all installations or configurations. The terms first, second, third, etc. can be used herein to describe various elements, components, regions, layers and / or sections. These elements, components, regions, layers and / or sections should not be limited by these terms. These terms are only used to distinguish one element, component, region, layer or section from another region, layer or section. Terms such as "first," "second," and other numerical terms do not imply a sequence or order unless the context clearly dictates. Thus, a first element, component, region, layer or section discussed below could be termed a second element, component, region, layer or section without departing from the teachings of the example configurations.

[0046] The present disclosure relates to an article of footwear and / or particular components of the article of footwear, such as an upper and / or a sole or sole structure. The upper can include a knit component, a woven textile, and / or a nonwoven textile. The knit component can be made from knit yarns, the woven textile is made from woven yarns, and the nonwoven textile is made from a unitary nonwoven web. The knit textile includes a fabric formed by warp knitting, weft knitting, flat knitting, circular knitting, and / or other suitable knitting operations. For example, the knit textile can have a flat knit structure, a mesh knit structure, and / or a rib knit structure. The woven textile includes, but is not limited to, a fabric formed by any of a variety of weaving forms, such as plain weave, twill weave, satin weave, dobby weave, jacquard weave, double weave, and / or double cloth fabric. The nonwoven textile includes a fabric made, for example, by air-laying and / or spun-laying processes. The upper can include a variety of materials, such as a first yarn, a second yarn, and / or a third yarn, which can have different properties or different visual characteristics.

[0047] The following discussion and accompanying figures disclose various embodiments or configurations of an article of footwear. The article of footwear can be provided as a pair of shoes, including a first shoe or left shoe and a second shoe or right shoe. The left shoe and the right shoe can be similar in all materials, except that the left shoe and the right shoe accommodate the user’s left foot and right foot, respectively, in terms of size and shape. To facilitate disclosure, reference will be made to a single shoe or article of footwear to describe various aspects of the present disclosure. In some figures, the article of footwear is depicted as a right shoe, while in some figures, the article of footwear is depicted as a left shoe. The following disclosure regarding the article of footwear applies to both the left shoe and the right shoe. In some embodiments, there can be differences between the left shoe and the right shoe, in addition to the left / right configuration. For example, in some embodiments, the left shoe can include a fastening mechanism, while the right shoe can not include a fastening mechanism, or vice versa. Further, in some embodiments, the left shoe can include one or more additional elements that the right shoe does not include, or vice versa.

[0048] Reference Figures 1-3 is shown, illustrating an exemplary embodiment of an article of footwear 100, including an upper 102 and a sole structure 104. The upper 102 is attached to the sole structure 104, and together define an interior void 106 (see Figure 2 and Figure 3 ) into which a user’s foot can be inserted. For reference, the article of footwear 100 defines a forefoot region 108, a midfoot region 110, and a heel region 112 (see Figure 2 and Figure 3 ). The forefoot region 108 generally corresponds with the portions of the article of footwear 100 that wrap the portions of the foot including the toes, the ball of the foot, and the joints connecting the metatarsal bones with the toes or phalanges. The midfoot region 110 is proximate and adjacent to the forefoot region 108, and generally corresponds with the portions of the article of footwear 100 that wrap the arch of the foot, as well as the bridge of the foot. The heel region 112 is proximate and adjacent to the midfoot region 110, and generally corresponds with the portions of the article of footwear 100 that wrap the rear of the foot, including the heel or calcaneus, the ankle, and / or the Achilles tendon.

[0049] Many conventional articles of footwear have uppers formed from a plurality of elements (e.g., fabric, polymeric foam, polymeric sheeting, leather, and synthetic leather) that are joined together through adhesion or stitching at seams. In some embodiments, the upper 102 of the article of footwear 100 is formed from a knit structure or knit component. In various embodiments, the knit component can incorporate various types of yarns that can provide 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 set of properties, while another region of the upper 102 can be formed from a second type of yarn that imparts a second set of properties. With this configuration, the properties of the upper 102 can vary throughout the upper 102 by selecting particular yarns for different regions of the upper 102.

[0050] With respect to the materials that make up the upper 102, the particular properties that a particular type of yarn will impart to a region of the knitted component can 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 feel, biodegradability, or a natural aesthetic to the knitted material. Spandex and stretch polyester can each provide the desired elasticity and recovery properties to the knitted component. Rayon can provide a high luster and moisture absorbent material, wool can provide a moisture absorbent enhanced material, nylon can be a durable material that is resistant to abrasion, and polyester can provide a durable material that is hydrophobic.

[0051] Other aspects of the knitted component can also vary to affect the properties of the knitted component and provide the desired attributes. For example, the yarns that form the knitted component can include single filament yarns or multi-filament yarns, or the yarns can include filaments that are each formed from two or more different materials. Further, the knitted component can be formed using a particular knitting process to impart particular properties to regions of the knitted component. Thus, the materials that form the yarns and other aspects of the yarns can be selected to impart a variety of properties to particular regions of the upper 102.

[0052] In some embodiments, the elasticity of the knitted structure can be measured based on comparing a width or length of the knitted structure in a first, non-stretched state to a width or length of the knitted structure in a second, stretched state after the knitted structure has had a force applied to it in the lateral direction. In further embodiments, the upper 102 can also include additional structural elements. For example, in some embodiments, a heel counter or overlay (not shown) can be disposed on the heel region 112 to provide additional support to the heel of the user's foot. In certain instances, other elements, such as plastic materials, logos, trademarks, and the like can also be applied and secured to the outer surface using a glue or thermoforming process. In some embodiments, the properties associated with the upper 102, such as the stitch type, the yarn type, or properties associated with different stitch types or yarn types, such as elasticity, aesthetic, thickness, breathability, or abrasion resistance can vary.

[0053] Referring again to Figure 1The sole structure 104 is connected or fixed to the upper 102 and extends between the user's foot and the ground when the article of footwear 100 is worn by the user. The sole structure 104 can include one or more components, which can include an outsole, a midsole, a heel, a vamp, and / or an insole. For example, in some embodiments, the sole structure can include an outsole that provides structural integrity to the sole structure and provides traction for the user, a midsole that provides a cushioning system, and an insole that provides support for the user's arch. Further, the insole can be a strobel board, a forefoot plate, a durability plate, or the like, or combinations thereof, and the insole can be disposed between the upper 102 and the sole structure 104, or the insole can be disposed as part of the upper 102.

[0054] Further, the insole can be located in a void of the upper 102, which can be in direct contact with the user's foot when the article of footwear 100 is worn. Further, the upper 102 can also include a liner (not shown), which can increase comfort, for example, by reducing friction between the user's foot and the upper 102, the sole structure 104, the insole, or the like, and / or by providing sweat-absorbing properties. The liner can line the entire void of the upper 102 or only a portion thereof. In some embodiments, a gasket (not shown) can surround an opening of the void of the upper 102 to secure the liner to the upper 102 and / or to provide an aesthetic element on the article of footwear 100.

[0055] With reference to Figure 2 and Figure 3 The article of footwear 100 also defines a lateral side 116 and a medial side 118. When worn by a user, the lateral side 116 corresponds to an outward-facing portion of the article of footwear 100, while the medial side 118 corresponds to an inward-facing portion of the article of footwear 100. As such, the article of footwear 100 has opposing lateral and medial sides 116, 118. The lateral and medial sides 116, 118 adjoin one another along a longitudinal center plane or axis 120 of the article of footwear 100, which is coplanar with a longitudinal axis L of the article of footwear 100. Figure 1 As will be discussed further herein, the longitudinal center plane or axis 120 can divide a center neutral axis between the lateral side 116 and the medial side 118 of the article of footwear 100. In other words, the longitudinal plane or axis 120 can extend between a posterior proximal end 122 of the article of footwear 100 and an anterior distal end 124 of the article of footwear 100, and can continuously define a midfoot portion of the insole 126, the sole structure 104, and / or the upper 102 of the article of footwear 100, i.e., the longitudinal plane or axis 120 is a straight axis that extends through the proximal end 122 of the heel region 112 to the distal end 124 of the forefoot region 108.

[0056] Unless otherwise noted, referenceFigure 2 And Figure 3 The article of footwear 100 can be defined by a forefoot region 108, a midfoot region 110, and a heel region 112. The forefoot region 108 can generally correspond to portions of the article of footwear 100 that enclose the toes or phalanges 130, the ball of the foot or hallux 132, and one or more joints 134 connecting the metatarsals 136 and the toes or phalanges 130 of the foot 128. The midfoot region 110 is proximate to and adjacent with the forefoot region 108. The midfoot region 110 generally corresponds to portions of the article of footwear 100 that enclose the arch of the foot 128 and the instep of the foot 128. The heel region 112 is proximate to and adjacent with the midfoot region 110. The heel region 112 generally corresponds to portions of the article of footwear 100 that enclose the rear of the foot 128, including the heel or calcaneus 138, the ankle (not shown), and / or the Achilles tendon (not shown).

[0057] Still referring to Figure 2 And Figure 3 The forefoot region 108, the midfoot region 110, the heel region 112, the lateral side 116, and the medial side 118 are intended to define the boundaries or areas of the article of footwear 100. To this end, the forefoot region 108, the midfoot region 110, the heel region 112, the lateral side 116, and the medial side 118 generally characterize portions of the article of footwear 100. Certain aspects of the present disclosure can refer to portions or elements that extend coextensively with one or more of the forefoot region 108, the midfoot region 110, the heel region 112, the lateral side 116, and / or the medial side 118. Further, both the upper 102 and the sole structure 104 are characterized as having portions that lie within the forefoot region 108, the midfoot region 110, the heel region 112, and / or along the lateral side 116 and / or the medial side 118. Accordingly, the upper 102 and the sole structure 104, and / or individual portions of the upper 102 and the sole structure 104, can include portions disposed within the forefoot region 108, the midfoot region 110, the heel region 112, and / or along the lateral side 116 and / or the medial side 118.

[0058] Still referring to Figure 2 And Figure 3The forefoot region 108, the midfoot region 110, the heel region 112, the lateral side 116, and the medial side 118 are shown in detail. The forefoot region 108 extends from a toe end 140 of the article of footwear 100 to a widest portion 142. The widest portion 142 is defined or measured along a first line 144 that is perpendicular to a longitudinal axis 120 that extends from a distal portion of the toe end 140 to a distal portion of a heel end 146, which is opposite the toe end 140. The midfoot region 110 extends from the widest portion 142 of the article of footwear 100 to a narrowest portion 148. The narrowest portion 148 of the article of footwear 100 is defined as the narrowest portion of the article of footwear 100 measured across a second line 150 that is perpendicular to the longitudinal axis 120. The heel region 112 extends from the narrowest portion 148 of the article of footwear 100 to the heel end 146.

[0059] It should be appreciated that in light of the foregoing description, many modifications will be apparent to those of ordinary skill in the art and that individual components thereof can be incorporated into a number of articles of footwear. Accordingly, various aspects of the article of footwear 100 and components thereof can be described with reference to general regions or portions of the article of footwear 100, with the understanding that boundaries of the forefoot region 108, the midfoot region 110, the heel region 112, the lateral side 116, and / or the medial side 118 as described herein can vary between articles of footwear. However, aspects of the article of footwear 100 and individual components thereof can also be described with reference to exact regions or portions of the article of footwear 100, and the scope of the claims appended herein can incorporate limitations related to these boundaries of the forefoot region 108, the midfoot region 110, the heel region 112, the lateral side 116, and / or the medial side 118 described herein.

[0060] Still referring to Figure 2 and Figure 3 The medial side 118 begins at the distal toe end 140 and curves outward along the medial side of the article of footwear 100 along the forefoot region 108 toward the midfoot region 110. The medial side 118 reaches the first line 144 at which point the medial side 118 curves inward toward the central longitudinal axis 120. The medial side 118 extends from the first line 144 (i.e., the widest portion 142) to the second line 150 (i.e., the narrowest portion 148) at which point the medial side 118 enters the midfoot region 110, i.e., upon crossing the first line 144. Upon reaching the second line 150, the medial side 118 curves outward, away from the longitudinal central axis 120, at which point the medial side 118 extends into the heel region 112, i.e., upon crossing the second line 150. The medial side 118 then curves outward and then inward toward the heel end 146 and terminates at the point at which the medial side 118 intersects the longitudinal central axis 120.

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

[0062] Still referring to Figure 2 and Figure 3 The upper 102 extends along the lateral side 116 and the medial side 118 and across the forefoot region 108, the midfoot region 110, and the heel region 112 to accommodate and enclose the user’s foot. When fully assembled, the upper 102 also includes an interior surface 152 and an exterior surface 154. The interior surface 152 faces inward and generally defines the interior void 106, while the exterior surface 154 of the upper 102 faces outward and generally defines the outer perimeter or boundary of the upper 102. The upper 102 also includes an opening 156 that is at least partially located in the heel region 112 of the article of footwear 100 that provides access to the interior void 106 and through which the user’s foot can be inserted and removed. In some embodiments, the upper 102 can also include an instep region 158 that extends from the opening 156 in the heel region 112 to a region corresponding to the instep of the user’s foot and to a region proximate to the forefoot region 108. The instep region 158 can include an area where a tongue 160 of the present embodiment is disposed. In some embodiments, the upper 102 does not include a tongue 160, i.e., the upper 102 is tongueless.

[0063] In the illustrated embodiment, the sole structure 104 includes a midsole 162 and an outsole 164. The outsole 164 can define a bottom end or bottom surface 166 of the sole structure 104 that spans the forefoot region 108, the midfoot region 110, and the heel region 112. Further, the outsole 164 can be the ground-engaging portion of the sole structure 104, or include a ground-engaging surface, and can be opposite the insole 126 (see Figure 2 ) of the article of footwear 100. As Figure 1As shown, the bottom surface 166 of the outsole 164 can include a tread pattern 168, which can include a variety of shapes and configurations. The outsole 164 can be formed from one or more materials to impart durability, wear resistance, abrasion resistance, or traction to the sole structure 104. In some embodiments, the outsole 164 can be formed from any kind 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 164 can define a Shore A hardness of up to 95. Further, the outsole 164 can be manufactured by processes including injection molding, vulcanization, layer-by-layer printing, i.e., additive manufacturing systems or methods, and the like.

[0064] Still referring to Figure 1 , the midsole 162 can be configured from a thermoplastic material, such as polyurethane (PU), e.g., and / or ethylene-vinyl acetate (EVA), copolymers thereof, or similar types of materials. In other embodiments, the midsole 162 can be an EVA solid sponge (“ESS”) material, an EVA foam (e.g., ProFoam Lite™, IGNITE Foam), polyurethane, polyether, olefin block copolymer, organic sheet, thermoplastic material (e.g., thermoplastic polyurethane, thermoplastic elastomer, thermoplastic polyolefin, etc.), or a supercritical foam. The midsole 162 can be a single polymeric material, or can be a mixture of multiple materials, such as EVA copolymers, thermoplastic polyurethane, polyether block amide (PEBA) copolymers, and / or olefin block copolymers. One example of a PEBA material is In some embodiments, the midsole 162 is manufactured by processes involving injection molding, vulcanization, layer-by-layer printing, i.e., additive manufacturing systems or methods, and the like.

[0065] In embodiments where the midsole 162 is formed from a supercritical foaming process, the supercritical foam can include a microcellular foam or a cellular foam, such as TPU, EVA, or mixtures thereof, using a process conducted in an autoclave, injection molding equipment, or any adequately heated / pressurized vessel capable of handling the mixing of a supercritical fluid (e.g., CO2, N2, or mixtures thereof) with a preferably molten material (e.g., TPU, EVA, polyolefin elastomer, or mixtures thereof). In an exemplary process, a solution of supercritical fluid and molten material is pumped into a pressurized vessel, after which the pressure is released within the vessel, causing the molecules of the supercritical fluid to rapidly transform into a gas, forming small pockets within the material and expanding the material into a foam. In further embodiments, the midsole 162 can be formed using alternative methods known in the art, including the use of an expansion press, injection machine, pellet expansion process, cold foaming process, compression molding techniques, die cutting, or any combination thereof. For example, the midsole 162 can 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 particular shape.

[0066] Referring now to Figure 4 , an exemplary article of footwear 200 is shown that includes a fastening mechanism 270 having a loop or tension member 272 that is operatively engaged or coupled with a thread or tension element 274 to at least tighten and / or loosen the upper 202 of the article of footwear 200 around a user's foot. The article of footwear 200 is similar to the previously described embodiments, with like elements denoted by like reference numerals under the "2xx" and "3xx" series. For example, the article of footwear 200 includes an upper 202 that defines an opening 256 into an interior void 206 thereof and a sole structure 204 that includes a midsole 262 and an outsole 264, just as the article of footwear 100 includes an upper 102 and a sole structure 104.

[0067] In Figure 4In the illustrated embodiment, the tensioning member 272 of the article of footwear 200 includes a first or outer tensioning member 276 having a first or outer member opening 278 and a second or inner tensioning member 280 having a second or inner member opening 282. The inner tensioning member 280 is disposed within the outer member opening 278 of the outer tensioning member 276 such that a first or outer central axis of the outer tensioning member 276 and a second or inner central axis of the inner tensioning member 280 are aligned and parallel, i.e., coaxial, about a tensioning member axis 284. In other words, the outer tensioning member 276 is a first or outer ring and the inner tensioning member 280 is a second or inner ring disposed within the outer ring. In some embodiments, the inner tensioning member 280 can not include the inner member opening 282. In the illustrated embodiment, the tensioning member 272, i.e., the outer tensioning member 276 and the inner tensioning member 280, is disposed on or along the instep region 258 of the upper 202 of the article of footwear 200 and at least partially within each of the midfoot region 210 and the heel region 212. In some embodiments, the tensioning member 272 can be disposed on or along the instep region 258 adjacent the opening 256 of the upper 202. In some embodiments, the tensioning member 272 is disposed entirely within the midfoot region 210. In some embodiments, the tensioning member 272 is at least partially disposed within the forefoot region 208. In some embodiments, the tensioning member 272 can be disposed on or along a tongue (not shown) of the upper 202, such as on the tongue 160 (see Figure 2 ) of the article of footwear 100.

[0068] Still referring to Figure 4 , the tensioning element 274 of the fastening mechanism 270 is generally configured to be tensioned by the tensioning member 272 to tighten or loosen the fastening mechanism 270 about the upper 202. In the illustrated embodiment, the tensioning element 274 includes a first or lateral tensioning element 288 and a second or medial tensioning element 290 (see Figure 5 and Figure 6). The outer tensioning element 288 extends from the sole structure 204 (such as the midsole 262 thereof) along the lateral side 216 of the upper 202 to a first or lateral side 292 of the outer tensioning member 276, and the inner tensioning element 290 extends from the sole structure 204 (such as the midsole 262 thereof) along the medial side 218 of the upper 202 to a second or medial side 294 of the outer tensioning member 276. In some embodiments, the fastening mechanism 270 can include three or more tensioning elements 274. For example, in some embodiments, the fastening mechanism 270 can further include a third or distal tensioning element (not shown) extending from the distal end 224 of the sole structure 204 to the outer tensioning member 276 along the instep region 258 of the upper 202, and / or a fourth or proximal tensioning element (not shown) extending from the proximal end 222 of the sole structure 204 to the outer tensioning member 276 along the lateral side 216 and / or the medial side 218 of the upper 202.

[0069] With continued reference to Figure 4 In the illustrated embodiment, the outer tensioning elements 288 include a first outer tensioning element 298 disposed toward the proximal end 222 of the article of footwear 200, a second outer tensioning element 300 disposed adjacent the first outer tensioning element 298, a third outer tensioning element 302 disposed adjacent the second outer tensioning element 300, a fourth outer tensioning element 304 disposed adjacent the third outer tensioning element 302, a fifth outer tensioning element 306 disposed adjacent the fourth outer tensioning element 304, and a sixth outer tensioning element 308 disposed adjacent the fifth outer tensioning element 306 and toward the distal end 224 of the article of footwear 200. In other words, the outer tensioning elements 298, 300, 302, 304, 306, 308 are arranged in series along the lateral side 216 of the upper 202, with the first outer tensioning element 298 being closest to the proximal end 222 and the sixth outer tensioning element 306 being closest to the distal end 224. In the illustrated embodiment, one or more of the outer tensioning elements 298, 300, 302, 304, 306, 308 are disposed in each of the forefoot region 208, the midfoot region 210, and the heel region 212 of the article of footwear 200. In some embodiments, the outer tensioning elements 298, 300, 302, 304, 306, 308 can be disposed entirely in the midfoot region 210 of the article of footwear 200.

[0070] With reference to Figure 6 The inner tensioning elements 290 include a first inner tensioning element 292 disposed toward the proximal end 222 of the article of footwear 200 (see Figure 4) a first inner tensioning element 310 disposed, a second inner tensioning element 312 disposed adjacent the first inner tensioning element 310, a third inner tensioning element 314 disposed adjacent the second inner tensioning element 312, a fourth inner tensioning element 316 disposed adjacent the third inner tensioning element 314, a fifth inner tensioning element 318 disposed adjacent the fourth inner tensioning element 316, and a sixth inner tensioning element 320 disposed adjacent the fifth inner tensioning element 318 and toward the distal end 224 (see Figure 4 ) of the article of footwear 200. In other words, similar to the outer tensioning elements 298, 300, 302, 304, 306, 308, the inner tensioning elements 310, 312, 314, 316, 318, 320 are arranged in series along the medial side 218 of the upper 202, with the first inner tensioning element 310 closest to the proximal end 222 and the sixth inner tensioning element 294 closest to the distal end 224 (see Figure 4 ) of the article of footwear 200. In the illustrated embodiment, similar to the outer tensioning elements 298, 300, 302, 304, 306, 308, one or more of the inner tensioning elements 310, 312, 314, 316, 318, 320 are disposed in each of the forefoot region 208, the midfoot region 210, and the heel region 212 of the article of footwear 200 (see Figure 4 ) of the article of footwear 200. In some embodiments, the inner tensioning elements 310, 312, 314, 316, 318, 320 can be disposed entirely in the midfoot region 210 (see Figure 4 ) of the article of footwear 200.

[0071] Referring to Figure 4 and Figure 5 , the fastening mechanism 270 is configured to be switchable between an initial or loosened configuration (as shown in Figure 4 and Figure 6 ) and a cinched configuration (as shown in Figure 5 and Figure 7between the first and second tensioning configurations, the tensioning elements 274 (i.e., the outer tensioning element 288 and the inner tensioning element 290) are tensioned to a first tension in the initial or loosened configuration, and in the cinched configuration, the tensioning elements 274 (i.e., one or both of the outer tensioning element 288 and the inner tensioning element 290) are tensioned to a second tension greater than the first tension by rotation of the inner tensioning member 280 relative to the outer tensioning member 276. It should be appreciated that the first and second tensions are intended to refer to the amount or magnitude of tension, which can not include the amount or magnitude of tension, and reference to a particular tension, i.e., the first and second tensions, refers to the tension applied by the tensioning member 272 to the tensioning elements 274, which can not include the tension. In particular, in the illustrated embodiment, the outer tensioning member 276 is fixedly attached to the upper 202, and the inner tensioning member 280 is configured to be rotatable within the outer tensioning member 276 about a tensioning member axis 284 in a first direction 324 and a second direction 326 opposite the first direction 324. The outer tensioning member 276 and the inner tensioning member 280 are configured such that an outer circumference 328 of the inner tensioning member 280 continuously contacts an inner circumference 330 of the outer tensioning member 276 opposite an outer circumference 332 of the outer tensioning member 276 while the inner tensioning member 280 is rotated.

[0072] Still referring to Figure 4 and Figure 5first ends 298a, 300a, 302a, 304a, 306a, 308a of the outer tensioning elements 298, 300, 302, 304, 306, 308, respectively (collectively referred to as the first ends 288a of the outer tensioning elements 288), are fixedly attached to the sole structure 204, and the outer tensioning elements 298, 300, 302, 304, 306, 308 extend along the lateral side 216 of the upper 202 toward the lateral side 292 of the outer tensioning member 276. Similarly, the first ends 310a, 312a, 314a, 316a, 318a, 320a (not shown) of the inner tensioning elements 310, 312, 314, 316, 318, 320, respectively (collectively referred to as the first ends 290a of the inner tensioning elements 290), are fixedly attached to the sole structure 204, and the inner tensioning elements 310, 312, 314, 316, 318, 320 extend along the medial side 218 of the upper 202 toward the medial side 294 of the outer tensioning member 276. In some embodiments, the upper 202 can define one or more tensioning element receptacles (not shown) configured to receive at least a portion of one or more of the outer tensioning elements 288 or the inner tensioning elements 290 between the first ends 288a, 290a and the outer tensioning member 276. For example, in some embodiments, the upper 202 can include a first or inner layer (not shown) at least partially defining the interior surface 252 of the upper 202 and a second or outer layer (not shown) at least partially defining the exterior surface 254 of the upper 202, and one or both of the outer tensioning elements 288 and the inner tensioning elements 290 can extend at least partially between the inner layer and the outer layer of the upper 202. In some embodiments, the article of footwear 200 can be configured such that the first ends 288a, 290a of the outer tensioning elements 288 and the inner tensioning elements 290 can slide along the sole structure 204 between the proximal end 222 and the distal end 224. In some embodiments, the tensioning elements 274 can include one or more tensioning elements that extend from the lateral side 292 of the outer tensioning member 276 along the lateral side 216 of the upper 202 and around the upper 202 between the sole structure 204 to the medial side 218 of the upper 202 to the medial side 294 of the outer tensioning member 276.

[0073] Reference is now made to Figure 6 and Figure 7In the illustrated embodiment, the outer tension member 276 has a non-circular shape, where the outer sides 292 and the inner sides 294 are generally straight and parallel to each other, and the sides connecting the outer sides 292 and the inner sides 294 are curved, i.e., an elliptical shape or an oval shape. In other words, the outer sides 292 and the inner sides 294 are elongated relative to the sides of the outer tension member 276 connecting the outer sides 292 and the inner sides 294. As such, the inner tension member 280 can be configured such that at least a portion of the inner tension member 280 is elastically deformable, and thus can adapt to the fixed shape of the inner periphery 330 of the outer tension member 276 as the inner tension member 280 is rotated therein. For example, in some embodiments, the outer tension member 276 can comprise a first material, and the inner tension member 280 can comprise a second material having different properties than the first material. In some embodiments, the outer tension member 276 can comprise a rigid material, and the inner tension member 280 can comprise an elastic or flexible material. In some embodiments, the outer periphery 332 of the outer tension member 276 has a shape that is different than the inner periphery 330 of the outer tension member 276. For example, in some embodiments, the outer periphery 332 of the outer tension member 276 can have a rectangular or square shape, and the inner periphery 330 has a circular or elliptical shape. In some embodiments, at least the inner periphery 330 of the outer tension member 276 has a generally circular shape, and thus the outer periphery 328 of the inner tension member 280 has a generally circular shape. In some embodiments, at least the inner periphery 330 of the outer tension member 276 can have a regular or irregular polygonal shape, such as a triangular, quadrilateral, pentagonal, hexagonal, or octagonal shape. In such embodiments, the inner tension member 280 can have the same or a different shape than the outer tension member 276. In some embodiments, the elongated sides 292, 294 of the outer tension member 276 can extend in a direction that is substantially parallel to a longitudinal central plane or axis 220 (see FIG. 1) of the article of footwear 200. Figure 5 ) of the article of footwear 200.

[0074] With particular reference to Figure 6The inner tensioning member 280 includes a channel 336, shown in dashed lines, disposed along the outer periphery 328 of the inner tensioning member 280. The channel 336 is configured to receive portions of the outer and inner tensioning elements 288, 290 when the fastening mechanism 270 is in the cinched configuration. The channel 336 of the inner tensioning member 280 has an outwardly facing open side (not shown) such that, when the inner tensioning member 280 is disposed within the inner periphery 330 of the outer tensioning member 276, the inner periphery 330 of the outer tensioning member 276 at least partially encloses the channel 336. The second ends 298b, 300b, 302b, 304b, 306b, 308b of the first, second, third, fourth, fifth, and sixth outer tensioning elements 298, 300, 302, 304, 306, 308 (collectively, second ends 288b of the outer tensioning elements 288) extend through respective holes 338 disposed on the outer side 292 of the outer tensioning member 276 and are fixedly attached within the channel 336 along the first or outer portion 280a of the inner tensioning member 280, respectively. Similarly, the second ends 310b, 312b, 314b, 316b, 318b, 320b of the first, second, third, fourth, fifth, and sixth inner tensioning elements 310, 312, 314, 316, 318, 320 (collectively, second ends 290b of the inner tensioning elements 290) extend through respective holes 338 disposed on the inner side 294 of the outer tensioning member 276 and are fixedly attached within the channel 336 along the second or inner portion 280b (opposite the outer portion 280a) of the inner tensioning member 280, respectively.

[0075] Referring to Figure 7 When the inner tensioning member 280 is rotated in the first direction 324 within the inner periphery 330 of the outer tensioning member 276, the fixedly attached second ends 288b, 290b of the outer and inner tensioning elements 288, 290 move with the inner tensioning member 280 in the first direction 324. Accordingly, rotation of the inner tensioning member 280 in the first direction 324 causes the outer and inner tensioning elements 288, 290 to be simultaneously drawn into the holes 338 of the outer tensioning member 276, while portions of the outer and inner tensioning elements 288, 290 adjacent the second ends 288b, 290b are wound or wrapped within the channel 336 of the inner tensioning member 280 (for purposes of illustration, Figure 7Only the position of the second ends 288b, 290b of the outer and inner tensioning elements 288, 290 are depicted, while the first ends 288a, 290a of the outer and inner tensioning elements 288, 290 remain fixed to the sole structure 204. In some embodiments, at least a portion of the outer and / or inner tensioning members 276, 280 can comprise a translucent or transparent material, such that the portions of the outer and inner tensioning elements 288, 290 wrapped within the channel 336 are visible from the exterior of the article of footwear 200. In some embodiments, the channel 336 or a second channel (not shown) can be defined along the inner periphery 330 of the outer tensioning member 276. In some embodiments, the inner tensioning member 280, and thus the second ends 288b, 290b of the outer and inner tensioning elements 288, 290, can be fixedly attached to the upper 202, and the outer tensioning member 276 can be rotatable relative to the inner tensioning member 280. As noted above, in some embodiments, the inner tensioning member 280 can not include the inner member opening 282, and in such embodiments, the inner tensioning member 280 can be rotatably attached to the upper 202, and can be rotatable relative to the outer tensioning member 276 about the tensioning member axis 284 (see Figure 5 ).

[0076] As shown in Figure 7 , and as a result of the portions of the outer and inner tensioning elements 288, 290 being wrapped around the channel 336 of the inner tensioning member 280 (i.e., the tensioning mechanism 270 is in the cinched configuration), the outer and inner tensioning elements 288, 290 are tensioned to a second tension along the lateral side 216 and the medial side 218 of the upper 202, respectively (see Figure 5 ). Further, the outer and inner tensioning elements 288, 290, when tensioned to the second tension, are in contact with the upper 202, which causes the upper 202 to be compressed or cinched at least along the lateral side 216 and the medial side 218 (see Figure 5 ). Further, the outer and inner tensioning elements 288, 290 pull the tensioning member 272 on the instep region 258 of the upper 202 (via the second ends 288b, 290b of the lateral and medial tensioning elements 288, 290 that are attached to the inner tensioning member 280, which is disposed within the fixed outer tensioning member 276) downward toward the sole structure 204 (see Figure 5 ), which can cinch or compress the upper 202 at least along the instep region 258.

[0077] It is contemplated that the tensioning mechanism 270 can be configured to provide a plurality of cinched configurations having different degrees of cinching from the uncinched configuration (shown in Figure 6 ) based on the amount of rotation of the inner tensioning member 280 relative to the outer tensioning member 276 in the first direction 324. For example, with reference to Figure 6 , the uncinched configuration (Figure 6 As shown, rotation of the internal tensioning member 280 in the first direction 324 causes the outer portion 280a and the inner portion 280b of the internal tensioning member 280 to move by approximately 10% of the total distance along the inner periphery 330 of the outer tensioning member 276, which can result in a first level of tightening (i.e., a first tightening configuration). Rotation of the internal tensioning member 280 in the first direction 324 causes the outer portion 280a and the inner portion 280b of the internal tensioning member 280 to move by approximately 20% of the total distance along the inner periphery 330 of the outer tensioning member 276, which can result in a second level of tightening (i.e., a second tightening configuration). Rotation of the internal tensioning member 280 in the first direction 324 causes the outer portion 280a and the inner portion 280b of the internal tensioning member 280 to move by approximately 30%, approximately 20%, or approximately 10% of the total distance along the inner periphery 330 of the outer tensioning member 276, which can result in a third level of tightening (i.e., a third tightening configuration), etc.

[0078] It is also conceivable that the tensioning member 272 may include a tension holding mechanism 340 (see Figures 6-9 The fastening mechanism 270 is configured to releasably retain the fastening mechanism 270 in one of a tightening configuration or multiple tightening configurations. For example, in some embodiments, the tension holding mechanism 340 may be arranged along the inner periphery 330 of the outer tensioning member 276 and the outer periphery 328 of the inner tensioning member 280 (e.g., Figures 6-9 (As shown), and can be configured to hold the inner tensioning member 280 within the outer tensioning member 276 to a desired degree of rotation, i.e., a desired tightening of the fastening mechanism 270, and to prevent rotational movement of the inner tensioning member 280 in at least a second direction 326. In some embodiments, the tension holding mechanism 340 of the fastening mechanism 270 may be a ratchet system. For example, in such an embodiment, the ratchet system of the fastening mechanism 270 may include a plurality of teeth arranged along the outer periphery 328 of the inner tensioning member 280 and one or more pivoting pawls arranged on the outer tensioning member 276, the pivoting pawls being configured to releasably engage the plurality of teeth of the inner tensioning member 280. In such an embodiment, one or more pivoting pawls of the ratchet system may be pivotable by one or more actuators, such as levers or buttons 346, which may be disposed on the outer tensioning member 276 or the upper 202 of the footwear article 200.

[0079] In some embodiments, the tension retention mechanism 340 of the fastening mechanism 270 can include a plurality of grooves defined in the outer periphery 328 of the inner tension member 280 that are configured to receive one or more protrusions extending inwardly from the inner periphery 330 of the outer tension member 276. In such embodiments, the inner tension member 280 can be configured to be vertically lifted by a user along the tension member axis 284 away from the sole structure 204 of the article of footwear 200, such that the grooves of the inner tension member 280 disengage from the protrusions of the outer tension member 276 (i.e., an unlocked position), rotated in the first direction 324 to achieve a desired degree of tightening, or rotated in the second direction 326 to loosen the fastening mechanism 270, and then lowered along the tension member axis 284 such that the grooves of the inner tension member 280 align with and receive the protrusions of the outer tension member 276 (i.e., a locked position). Accordingly, the grooves and protrusions of the outer tension member 276 and the inner tension member 280 can prevent rotational movement of the inner tension member 280 relative to the outer tension member 276 in one or both directions 324, 326. In such embodiments, the inner tension member 280 can be biased toward the locked position, for example, via a tension element 288, 290 or a coil spring (not shown).

[0080] Referring again to Figure 7 , the fastening mechanism 270 can be moved from the tightened configuration (as shown in Figure 7 ) back to the loosened configuration by rotation of the inner tension member 280 in the second direction 326 opposite the first direction 324. In some embodiments, the inner tension member 280 can be configured to be physically rotated by a user in the first direction 324 and the second direction 326. For example, referring again to Figure 4 and Figure 5 , the inner tension member 280 includes an outer protrusion 342 adjacent the outer portion 280a and an inner protrusion 344 adjacent the inner portion 280b (see Figure 6 and Figure 7 ). The outer protrusion 342 and the inner protrusion 344 each extend upwardly from the tension member 272 and are provided in the form of a knob or tab configured to be grasped by a hand of a user in order to rotate the inner tension member 280 in the first direction 324 and the second direction 326. In some embodiments, the fastening mechanism 270 can include a button 346 or other user-activated feature, for example on at least one of the protrusions 342, 344, that is configured to automatically move the fastening mechanism 270 from the tightened configuration to the loosened configuration. In other embodiments, the fastening mechanism 270 can include an electromechanical system that automatically moves the fastening mechanism 270 between the loosened configuration and the tightened configuration and / or one of a plurality of tightened configurations therebetween.

[0081] Referring to Figures 4-7Tensioning elements 274 can be constructed from a variety of materials, such as traditional cotton, nylon, or polyester, and can have a variety of shapes, such as a circular cross-section, to prevent twisting within the channel 336 of the inner tensioning member 280 and to improve the operation of the fastening mechanism 270. In some embodiments, the tensioning elements 274 include high modulus polyethylene fiber cables that have increased strength and abrasion resistance compared to traditional laces. In some embodiments, the tensioning elements 274 can include an elastic material to provide shock absorption to a user wearing the article of footwear 200. In some embodiments, the outer tensioning elements 288 can include a first material and the inner tensioning elements 290 can include a second material having different characteristics than the first material, such as different colors, widths, shapes, and / or elastic properties. Similarly, in some embodiments, for example, one or more of the outer tensioning elements 288 can include a first material and one or more other outer tensioning elements 288 can include a second material having different characteristics than the first material. In some embodiments, the tensioning elements 274, such as each of the outer tensioning elements 288 and the inner tensioning elements 290, have a diameter in a range between about 0.30 millimeters (mm) and about 3.0 mm, or between about 0.50 mm and about 2.5 mm, or between about 0.80 mm and about 2.0 mm, or between about 1.2 mm and about 1.7 mm. In some embodiments, one or more of the outer tensioning elements 288 and the inner tensioning elements 290 can have a different diameter than the other outer tensioning elements 288 and the inner tensioning elements 290.

[0082] With continued reference to Figures 4-7 It is contemplated that the tensioning member 272 can include three or more tensioning members, where one or more of the tensioning members can be disposed along the lateral side 216, the medial side 218, and / or the proximal end 222 of the upper 202. In such embodiments, the fastening mechanism 270 can be configured such that rotation of two or more of the tensioning members causes the fastening mechanism 270 to move between the loosened configuration and the tightened configuration. Further, in some embodiments, the tensioning elements 274 can include one or more tensioning elements 274 that extend from the lateral side 216 to the medial side 218 of the article of footwear 200 and through the tensioning member 272 disposed on the instep region 258 of the upper 202. In other embodiments, the outer tensioning elements 288 can include two to five or seven or more distinct outer tensioning elements and the inner tensioning elements 290 can include two to five or seven or more distinct inner tensioning elements. In some embodiments, the outer tensioning elements 288 can include more distinct tensioning elements than the inner tensioning elements 290, and vice versa.

[0083] Reference is now made to Figure 8 and Figure 9Another embodiment of the fastening mechanism 270 is described in which the outer tensioning elements 288 and the inner tensioning elements 290 are configured to form one or more loops extending from the sole structure 204 and are operably engaged or coupled with the tensioning member 272. Specifically, Figure 8 and Figure 9 The fastening mechanism 270 of the article of footwear 200 is similar to the previous embodiment of Figures 4-7 , like elements are designated by like reference numerals. In the embodiment shown in Figure 8 and Figure 9 , the outer tensioning elements 288 include a first outer tensioning element 298, a second outer tensioning element 300, and a third outer tensioning element 302 that are configured to form three outer tensioning loops extending along the lateral side 216 of the upper 202 (see Figure 4 and Figure 5 ). Similarly, the inner tensioning elements 290 include a first inner tensioning element 310, a second inner tensioning element 312, and a third inner tensioning element 314 that are configured to form three inner tensioning loops extending along the medial side 218 of the upper 202 (see Figure 4 and Figure 5 ).

[0084] With particular reference to Figure 8 , the first ends 298a, 300a, 302a of the first outer tensioning element 298, the second outer tensioning element 300, and the third outer tensioning element 302 extend from the lateral side 216 of the sole structure 204 toward the lateral side 292 of the outer tensioning member 276 such that the first portions 298c, 300c, 302c of the first outer tensioning element 298, the second outer tensioning element 300, and the third outer tensioning element 302 are adjacent the lateral side 216 of the upper 202 (see Figure 4 and Figure 5 ). The segments 298d, 300d, 302d of the first outer tensioning element 298, the second outer tensioning element 300, and the third outer tensioning element 302 extend from the first portions 298c, 300c, 302c through the respective holes 338 in the lateral side 292 of the outer tensioning member 276, through the respective tensioning element retainers 348 disposed within the channels 336 of the inner tensioning member 280 shown in phantom, and through the adjacent respective holes 338 in the lateral side 292 of the outer tensioning member 276 toward the sole structure 204.

[0085] The tensioning element retainer 348 is configured to slidably retain portions of the tensioning elements and can include various internal structures, such as holes or hooks, within the passage 336 of the inner tensioning member 280. The second portions 298e, 300e, 302e of the first 298, second 300, and third 302 outer tensioning elements extend from the outer tensioning member 276 along the lateral side 216 of the upper 202 proximate the first portions 298c, 300c, 302c of the sole structure 204, respectively. In some embodiments, the second portions 298e, 300e, 302e of the outer tensioning elements 298, 300, 302 can extend along the lateral side 216 of the upper 202 in a direction parallel to the first portions 298c, 300c, 302c, respectively. In other embodiments, the second portions 298e, 300e, 302e of the outer tensioning elements 298, 300, 302 can extend along the lateral side 216 of the upper 202 disposed at an angle relative to the first portions 298c, 300c, 302c.

[0086] Still referring to Figure 8 , the second ends 298b, 300b, 302b of the first 298, second 300, and third 302 outer tensioning elements can be fixedly connected to the sole structure 204 proximate the fixedly attached first ends 298a, 300a, 302a, respectively (see Figure 4 and Figure 5 ). Thus, in the illustrated embodiment, each of the first 298, second 300, and third 302 outer tensioning elements forms a fixed loop with the segment 298d, 300d, 302d that is slidably retained within the outer portion 280a of the inner tensioning member 280 via the tensioning element retainer 348. In some embodiments, one or more of the outer tensioning elements 298, 300, 302 can be closed loops, i.e., have connected first and second ends 298a, 298b, 300a, 300b, 302a, 302b, respectively, that are slidably received in one or more tensioning element receptacles (not shown) disposed on the lateral side 216 of the sole structure 204 and / or upper 202. In the illustrated embodiment, the first 310, second 312, and third 314 inner tensioning elements are configured similarly to the first 298, second 300, and third 302 outer tensioning elements such that the first 310c, 312c, 314c and second 310e, 312e, 314e portions of the first 310, second 312, and third 314 inner tensioning elements are proximate the medial side 218 of the upper 202, respectively (see Figure 4 and Figure 5The segments 310d, 312d, and 314d are slidably held within the inner portion 280b of the inner tensioning member 280 by the corresponding tensioning element retainer 348.

[0087] refer to Figure 9 In the illustrated embodiment, when the internal tensioning member 280 rotates along the first direction 324, the tensioning element retainer 348 moves along the first direction 324 with the internal tensioning member 280, and the fastening mechanism 270 moves to a tightened configuration. When the tensioning element retainer 348 rotates along the first direction 324, segments 298d, 300d, 302d, 310d, 312d, and 314d (for illustrative purposes) held within the respective tensioning element retainers 348 are... Figure 9 The points or portions (described as within the tensioning element retainer 348) slidably move together with the tensioning element retainer 348, causing the outer and inner tensioning elements 298, 300, 302, 310, 312, 314 to be tensioned to a second tension. When the second tension is reached, the outer and inner tensioning elements 298, 300, 302, 310, 312, 314 contact the upper 202, causing the upper 202 to be compressed or tightened at least along the outer side 216 and the inner side 218 (see...). Figure 4 and Figure 5 Furthermore, the outer and inner tensioning elements 298, 300, 302, 310, 312, and 314 on the instep area 258 of the upper 202 pull the tensioning member 272 downward toward the sole structure 204 via segments 298d, 300d, 302d, 310d, 312d, and 314d disposed within the tensioning element retainer 348. By rotating the inner tensioning member 280 in the second direction 326, the fastening mechanism 270 is adjusted from a tightened configuration (e.g., ...). Figure 9 (As shown) Move to the release configuration.

[0088] In other embodiments, the external tensioning element 288 may include one or more external tensioning elements forming an external tensioning ring having a segment operatively engaged or connected to the internal tensioning member 280, while the internal tensioning element 288 may include one or more internal tensioning elements having an end fixedly attached to the internal tensioning member 280 and other ends fixedly attached to the upper 202 and / or sole structure 204, and vice versa. In some embodiments, the external tensioning element 288 and the internal tensioning element 290 may form a closed loop having first and second portions extending along the outer side 216 and inner side 218 of the upper 202, a first segment received within the internal tensioning member 280, and a second segment received within one or more tensioning element receptacles (not shown) arranged on the upper 202 and / or sole structure 204.

[0089] Now for reference Figures 10-13Another example embodiment of an article of footwear 400 is depicted, which includes an upper 402, a sole structure 404, and a fastening mechanism 470. The article of footwear 400 is similar to the previous embodiments, with like elements denoted by like reference numerals under the “4xx” series and the “5xx” series. For example, the article of footwear 400 includes an upper 402 having an interior surface 452 and an exterior surface 454 and a sole structure 404 including a midsole 462 and an outsole 464, just as the article of footwear 100 includes an upper 402 and a sole structure 404. While the fastening mechanism 470 of the article of footwear 400 is similar in many respects to the previous embodiments, there are some different aspects. In particular, the tensioning member 472 of the fastening mechanism 470 includes a first or proximal tensioning member 476 and a second or distal tensioning member 480 that are arranged at a distance from one another and around different portions of the upper 402 and the sole structure 404 of the article of footwear 400. The tensioning element 474 of the fastening mechanism 470 extends between and is operably engaged or coupled to the proximal and distal tensioning members 476, 480 such that the fastening mechanism 470 can be tightened and / or loosened around a user’s foot.

[0090] Referring to Figure 10 and Figure 12 , the proximal and distal tensioning members 476, 480 each have a member opening 478, 482 having a first diameter D1 (see Figure 12 ) defined by an inner periphery or surface 530, 534 of the proximal and distal tensioning members 476, 480, respectively. The inner surfaces 530, 534 are opposite outer peripheries or surfaces 528, 532 of the proximal and distal tensioning members 476, 480, respectively. With reference to Figure 10 , the proximal and distal tensioning members 476, 480 each extend around different portions of the lateral side 416, the medial side 418 (see Figure 11 ) and the instep region 458 of the upper 402 and through a sole aperture 560 defined by the sole structure 404. In the illustrated embodiment, the sole aperture 560 extends through the midsole 462 of the sole structure 404 from the lateral side 416 to the medial side 418 of the sole structure 404. Thus, the inner surfaces 530, 534 of the proximal and distal tensioning members 476, 480 contact the lateral side 416, the medial side 418 and the instep region 458 of the upper 402 and, in some configurations, at least the upper side 562 of the sole aperture 560.

[0091] Referring to Figure 10 , in the illustrated embodiment, the tensioning members 476, 480 are concentrically aligned about a tensioning member axis 484 and extend along the tensioning member axis 484 for a length L1 (see Figure 12) spaced apart from one another. More specifically, the proximal tension member 476 is disposed toward the opening 456 of the upper 402 and proximate a first or proximal side 564 of the sole aperture 560, and the distal tension member 480 is disposed toward the distal end 424 of the upper 402 and proximate a second or distal side 566 of the sole aperture 560. In the illustrated embodiment, the proximal and distal tension members 476, 480 are fixed such that the length LI is constant. In some embodiments, the article of footwear 400 can be configured such that the proximal tension member 476 and / or the distal tension member 480 are laterally movable about the tension member axis 484 such that the length LI between the proximal tension member 476 and the distal tension member 480 is variable. In such embodiments, the proximal tension member 476 and / or the distal tension member 480 can be biased toward the proximal 564 and / or distal 566 sides of the sole aperture 560, respectively (i.e., toward the proximal end 422 and / or the distal end 424 of the article of footwear 400), such as by a biasing member disposed within the sole aperture 560.

[0092] With continued reference to Figure 10 In the illustrated embodiment, the aperture 560, and thus the proximal and distal tension members 476, 480, are located substantially in the midfoot region 410 of the sole structure 404. In other embodiments, the proximal tension member 476 can be located in the heel region 412 of the sole structure 404, and the distal tension member 480 can be located in the forefoot region 408 of the sole structure 404. In some embodiments, the tension member 472 can include only one of the proximal or distal tension members 476, 480 to which one end of the tensioning element 474 is fixedly attached, and the other end of the tensioning element 474 is fixedly attached to the upper 402 and / or the sole structure 404. In other embodiments, the tension member 472 can include three or more tension members, and one or more of the tension members can be disposed on the proximal end 422 of the upper 402 and / or the sole structure 404. In some embodiments, the sole structure 404 can include a plurality of sole apertures 560, for example a first sole aperture located in the forefoot region 408 configured to receive the distal tension member 480, and a second sole aperture located in the midfoot region 410 and / or the heel region 412 configured to receive the proximal tension member 476.

[0093] Still referring to Figure 10In the illustrated embodiment, the tensioning elements 474 include a plurality of tensioning elements each having a first or proximal end 474a fixedly attached to the proximal tensioning member 476 and a second or distal end 474b fixedly attached to the distal tensioning member 480. Thus, the plurality of tensioning elements 474 extend between the proximal and distal tensioning members 476, 480 and along portions of the upper 402 and sole structure 404 of the article of footwear 400. In some embodiments, one or more tensioning element receptacles (not shown) can be defined along the upper 202 between the tensioning members 476, 480 configured to receive at least a portion of one or more of the plurality of tensioning elements 474 between the proximal and distal ends 474a, 474b. In some embodiments, at least some of the plurality of tensioning elements 474 can have at least one of the proximal or distal ends 474a, 474b attached to the upper 202. For example, in some embodiments, at least some of the proximal ends 474a of the plurality of tensioning elements 474 can be fixedly attached to the upper 202 between the proximal tensioning member 476 and the proximal end 422 of the upper 202, and / or at least some of the distal ends 474b of the plurality of tensioning elements 474 can be fixedly attached to the upper 202 between the distal tensioning member 480 and the distal end 424 of the upper 202. In some embodiments, at least some of the plurality of tensioning elements 474 can have at least one of the proximal or distal ends 474a, 474b attached to the sole structure 404, such as to the upper side 562 of the sole aperture 560.

[0094] Referring to Figure 10 and Figure 11 , the fastening mechanism 470 of the article of footwear 400 is configured to be movable between a loosened configuration (shown in Figure 10 and Figure 12 ) in which the plurality of tensioning elements 474 are tensioned to a first tension, and a tightened configuration (shown in Figure 11 and Figure 13 ) in which the plurality of tensioning elements 474 are tensioned to a second tension greater than the first tension, by rotation of at least one of the proximal and distal tensioning members 476, 480. In particular, with the fastening mechanism 470 in the loosened configuration (as shown in Figure 10 and Figure 12 ), each of the plurality of tensioning elements 474 tensioned to the first tension extends parallel to the tensioning member axis 484 (and thus also parallel to each other) between the tensioning members 476, 480 and along the lateral side 416, the medial side 418, and the instep region 458 of the upper 402, and orthogonally with respect to the tensioning members 476, 480. Thus, the length of each tensioning element 474 is at least equal to the length LI (see Figure 12 ) between the tensioning members 476, 480.

[0095] Referring to Figure 11 , it is shown that the fastening mechanism 470 has been moved to the cinched configuration (shown) by the user rotating the proximal tension member 476 about the tension member axis 484 relative to the distal tension member 480 in the first direction 524. Figure 11 and Figure 13 , the proximal tension member 476 includes a protrusion 570 extending outwardly from an outer surface 528 of the proximal tension member 476 that is configured to be grasped by the user’s hand to rotate the proximal tension member 476. As the proximal tension member 476 is rotated in the first direction 524, the fixed first ends 474a of the plurality of tension members 474 move with the proximal tension member 476 in the first direction 524, while the second ends 474b of the plurality of tension members 474 remain fixed in place on the stationary distal tension member 480. Accordingly, rotation of the proximal tension member 476 relative to the distal tension member 480 in the first direction 524 causes each of the plurality of tension members 474 to extend along the upper 402 at an angle Θ relative to the tension member axis 484 and be tensioned to a second tension.

[0096] The plurality of tension members 474 tensioned to the second tension pull the lateral side 416 and the medial side 418 of the upper 402 inwardly, while also pulling the instep region 458 of the upper 402 downwardly toward the sole structure 404. As noted above, in the illustrated embodiment, the inner surfaces 530, 534 of the proximal and distal tension members 476, 480 are fixed to the upper portion 402 and the upper side 562 of the sole aperture 560 such that the length LI (see Figure 12 ) between the proximal and distal tension members 476, 480 is fixed. In other embodiments, the article of footwear 400 can be configured such that the plurality of tension members 474 tensioned to the second tension pull the distal tension member 480 laterally toward the proximal tension member 476 along the tension member axis 484 such that the length LI (see Figure 12 ) decreases when the fastening mechanism 470 is moved to the cinched configuration. In such embodiments, the distal tension member 480 can be biased toward the distal side 566 of the sole aperture 560. For example, in such embodiments, the upper side 562 of the sole aperture 560 can define a sole channel (not shown) that accommodates a portion of the distal tension member 480, and a biasing member (not shown) can be disposed within the sole channel that engages a portion of the distal tension member 480.

[0097] With continued reference to Figure 11In some embodiments, the fastening mechanism 470 can be moved from the loosened configuration to the tightened configuration by rotation of the proximal tension member 476 in the first direction 524 or a second direction 526 opposite the first direction 524. In such embodiments, the plurality of tension elements 474 extend at an angle that is inversely proportional to the angle Θ when the proximal tension member 476 is rotated in the second direction 526. In other embodiments, the fastening mechanism 470 can be configured such that the fastening mechanism 470 can be moved from the loosened configuration to the tightened configuration by rotation of the distal tension member 480 relative to the proximal tension member 476 in the first or second directions 524, 526. In some embodiments, the fastening mechanism 470 can be moved from the loosened configuration to the tightened configuration by rotation of the proximal tension member 476 in the first direction 524 and rotation of the distal tension member 480 in the second direction 526, and vice versa.

[0098] It is contemplated that at least the proximal tension member 476 can include a tension retention mechanism 540 (see Figure 10 ) configured to releasably retain the fastening mechanism 470 in the tightened configuration or one of a plurality of tightened configurations. For example, in some embodiments, the tension retention mechanism 540 of the fastening mechanism 470 can be disposed between the inner surface 530 (see Figure 12 ) and / or the outer surface 528 of the proximal tension member 476 and one or more sides of the sole aperture 560 and can be configured to releasably retain the proximal tension member 476 at a desired rotational angle relative to the distal tension member 480, i.e., a desired degree of tightening of the fastening mechanism 470, and prevent rotational movement of the proximal tension member 476 in at least the second direction 526. In other embodiments, the tension retention mechanism 540 can be disposed along a portion of the upper 402 and / or the sole structure 404 that is configured to releasably retain the proximal tension member 476. In some embodiments, the tension retention mechanism 540 of the fastening mechanism 470 can include a plurality of protrusions extending outwardly from the upper 402 that are configured to be received by one or more openings or grooves disposed on the inner surface 530 of the proximal tension member 476, and vice versa.

[0099] In some embodiments, the tension retention mechanism 540 of the fastening mechanism 470 (see Figure 10) can be a ratchet system. For example, in such embodiments, the ratchet system of the fastening mechanism 470 can include a plurality of teeth disposed along an inner surface 530 of the proximal tension member 476 and one or more pivoting pawls disposed on an upper, proximal, and / or distal side 562, 564, 566 of the sole aperture 560, the sole aperture 560 configured to releasably engage the plurality of teeth of the proximal tension member 476. In such embodiments, the one or more pivoting pawls of the ratchet system can be pivoted by one or more actuators, such as a lever or button 546, which can be disposed on the lateral side 416 and / or medial side 418 of the upper 402 or the sole structure 404 of the article of footwear 400. In other embodiments, the ratchet system of the fastening mechanism 470 can include a plurality of teeth disposed along an outer surface 528 of the proximal tension member 476 and one or more pivoting pawls disposed on the fourth or lower side of the sole aperture 560, the pivoting pawls configured to releasably engage the plurality of teeth of the proximal tension member 476. In such embodiments, the one or more pivoting pawls of the ratchet system can be pivoted by one or more actuators, such as a lever or button 546, which can be disposed on the lateral side 416 and / or medial side 418 of the upper 402 or the sole structure 404 of the article of footwear 400 and / or on the bottom surface 466 (see Figure 11 ) of the sole structure 404.

[0100] In some embodiments, the tension retention mechanism 540 of the fastening mechanism 470 can include a plurality of hooks and a plurality of loops, i.e., the corresponding male and female bands of a hook and loop fastener, such as Velcro®. In such embodiments, and with reference to Figure 11 , the plurality of hooks can be disposed along the inner surface 530 of the proximal tension member 476 proximate the protrusion 570 and the plurality of loops can be disposed along the instep region 458, lateral side 416, and / or medial side 418 of the upper 402 of the article of footwear 400 proximate the location of the proximal tension member 476. In such embodiments, and still with reference to Figure 11 , the proximal tension member 476 can be configured to elastically expand when the protrusion 570 is pulled outward by the user, such that the plurality of hooks on the inner surface 530 disengage a first portion of the plurality of loops of the upper 402, then can be rotated in the first direction 524 to a tightening configuration and / or in the second direction 526 to a loosening configuration, then can be released by the user, such that the proximal tension member 476 returns to its initial shape and the plurality of hooks on the inner surface 530 of the proximal tension member 476 re-engage a second portion of the plurality of loops on the upper 402.

[0101] With reference to Figures 10-13It is also conceivable that at least one of the proximal and distal tensioning members 476, 480 may be configured to elastically deform around a user's foot inserted into the upper 402, and thus also insert into openings 478, 482 of the proximal and distal tensioning members 476, 480 adjacent to the upper 402. For example, at least one of the proximal tensioning member 476 and / or the distal tensioning member 480 may comprise an elastic material such that the inner surfaces 530, 534 defining at least the openings 478, 482 of the proximal tensioning member 476 and the distal tensioning member 480 can: (i) from a first diameter D1 (see...) Figure 12 Elastic contraction to a second diameter D2 smaller than the first diameter D1 (see...) Figure 13 (ii) elastically expands from the first diameter D1 to a third diameter D3 (not shown) larger than the first diameter D1. In such an embodiment, when the fastening mechanism 470 is in a tightened configuration (e.g. Figure 11 and Figure 13 (as shown), at least the openings 478, 482 of the proximal and distal tensioning members 476, 480 can elastically contract to a second diameter D2 around the user's foot disposed in the inner cavity 406 of the upper 402 by a plurality of tensioning elements 474 tensioned to a second tension. Figure 13 ).

[0102] Similarly, in such an embodiment, when the fastening mechanism 470 is in the released configuration (e.g. Figure 10 and Figure 12 When the proximal tensioning member 476 and the distal tensioning member 480 are inserted into the inner cavity 406 through the opening 456 of the upper 402, the openings 478 and 482 can elastically deform to a third diameter D3 (not shown) so as to accommodate the wider portion of the user's foot, such as the ball of the big toe 132 of the foot 128 (see figure 128), when the user's foot is inserted into the inner cavity 406 through the opening 456 of the upper 402. Figure 3 It has a plurality of tensioning elements tensioned to a first tension. In some embodiments, at least a portion of the proximal tensioning member 476 may include a first material, and at least a portion of the distal tensioning member 480 may include a second material with less elasticity than the first material, or vice versa.

[0103] In some embodiments, the tensioning member 472 of the fastening mechanism 470 may include a connecting tube (not shown) attached to each of the proximal tensioning member 476 and the distal tensioning member 480, the connecting tube being configured to contact a portion of a user's foot between the tensioning members 476, 480 to provide enhanced support for the foot. In such an embodiment, at least a portion of the connecting tube (not shown) of the tensioning member 472 may include an elastic material to accommodate the user's foot. In such an embodiment, a plurality of tensioning elements 474 of the fastening mechanism 470 may extend along the outer surface of the connecting tube, or extend within the outer and inner surfaces of the connecting tube.

[0104] It is also conceivable that the fastening mechanism 470 can be configured such that the openings 478, 482 of the proximal and distal tensioning members 476, 480 are arranged only around the upper 402, i.e., not around the portion of the sole 404 via the sole hole 560. For example, the sole hole 560 could alternatively be a sole channel (not shown) extending through the sole interlayer 462 and the insole of the sole structure 404, for example... Figure 2 The insole 126 of the footwear article 100 is such that the open side of the sole channel extends upward from the sole structure 404 along the insole surface. In such an embodiment, at least one of the inner surfaces 530, 534 of the proximal and distal tensioning members 476, 480 can continuously contact the cross-section of the upper 402 along the tensioning member axis 484, providing direct support around the respective cross-section of the user's foot.

[0105] It can also be further envisioned that the fastening mechanism 470 may be configured to include two or more sets of tensioning elements 474 extending along the upper 402 at different or opposite angles θ, so that when the fastening mechanism 470 is in the tightened configuration, the pressure from the tensioning elements 474 is distributed more evenly along the upper 402. Now refer to Figure 14 and Figure 15 For example, another embodiment of the fastening mechanism 470 is described. Figure 14 and Figure 15 In the embodiment shown, the tensioning element 474 of the fastening mechanism 470 includes a first plurality of tensioning elements 580 and a second plurality of tensioning elements 582.

[0106] like Figure 14As shown, the first plurality of tensioning elements 580 each have a first end 580a fixedly attached to the upper 402 or the sole 404 below the inner surface 530 of the proximal tensioning member 476 and a second end 580b fixedly attached to the distal tensioning member 480. Further, the first plurality of tensioning elements 580 extend along the upper 402 between the proximal and distal tensioning members 476, 480 at a first angle θ1 relative to the tensioning member axis 484 and is measured in each of a first plurality of planes corresponding to and extending parallel to each of the first plurality of tensioning elements 580. The second plurality of tensioning elements 582 each have a first end 582a fixedly attached to the upper 402 or the sole 404 below the inner surface 534 of the distal tensioning member 480 and a second end 582b fixedly attached to the proximal tensioning member 476. Further, the second plurality of tensioning elements 582 extend along the upper 402 between the proximal and distal tensioning members 476, 480 at a second angle θ2 relative to the tensioning member axis 484 and is measured in each of a second plurality of planes corresponding to and extending parallel to each of the second plurality of tensioning elements 582, and each of the second plurality of planes corresponds to each of the respective first plurality of planes. In the illustrated embodiment, in each of the first and second plurality of planes, the second angle θ2 is an inverse of the first angle θ1 relative to the tensioning member axis 484, such that the first and second plurality of tensioning elements 580, 582 intersect each other along the upper 402 between the proximal and distal tensioning members 476, 480.

[0107] Referring again to Figure 14 and Figure 15 , the fastening mechanism 470 is configured to be movable between an initial or loosened configuration (shown in Figure 14 ) and a cinched configuration (shown in Figure 15 ), in which each of the first and second plurality of tensioning elements 580, 582 is tensioned to a first tension, and in which each of the first and second plurality of tensioning elements 580, 582 is tensioned to a second tension greater than the first tension. In the illustrated embodiment, the different tensions are achieved by rotation of each of the proximal and distal tensioning members 476, 480. As Figure 14As shown, with the fastening mechanism 470 in the loosened configuration, the first and second plurality of tensioning elements 580, 582 tensioned to the first tension extend in a crisscrossing manner along a portion of the upper 402 between the proximal and distal tensioning members 476, 480. In some embodiments, the fastening mechanism 470 can be configured such that the first and second plurality of tensioning elements 580, 582 tensioned to the first tension extend parallel to one another along the portion of the upper 402 between the proximal and distal tensioning members 476, 480. In some embodiments, the fastening mechanism 470 can be configured such that the first and second plurality of tensioning elements 580, 582 tensioned to the first tension extend at an angle measured in a plane perpendicular to an axis extending from each of the tensioning elements 580, 582 to the longitudinal axis 420 (see Figure 14 ) of the article of footwear 400, which is substantially parallel to the longitudinal axis 420 along the portion of the upper 402 between the proximal and distal tensioning members 476, 480.

[0108] With particular reference to Figure 15 , the fastening mechanism 470 is moved to the tightened configuration by rotation of the proximal tensioning member 476 in a first direction 524 about the tensioning member axis 484 and rotation of the distal tensioning member 480 in a second direction 526 opposite the first direction 524. As such, the proximal tensioning member 476 includes a proximal protrusion 570 and the distal tensioning member 480 includes a distal protrusion 586. The proximal protrusion 570 and the distal protrusion 586 each extend outwardly from the outer surfaces 528, 532, respectively, and are configured to be grasped by a user’s hand to rotate the proximal tensioning member 476 and the distal tensioning member 480. As the distal tensioning member 480 is rotated in the second direction 526, the second ends 580b of the first plurality of tensioning elements 580 move with the distal tensioning member 480 in the second direction while the first ends 580a remain fixed such that the first plurality of tensioning elements 580 extend along the upper 402 at a third angle Θ3 relative to the tensioning member axis 484 and the angle Θ3 measured in each of the first plurality of planes is greater than the first angle Θ1. Similarly, as the proximal tensioning member 476 is rotated in the first direction 524, the second ends 582b of the second plurality of tensioning elements 582 move with the proximal tensioning member 480 in the first direction 524 while the first ends 582a remain fixed such that the second plurality of tensioning elements 582 extend along the upper 402 at a fourth angle Θ4 relative to the tensioning member axis 484 and the angle Θ4 measured in each of the second plurality of planes is greater than the second angle Θ2 and is inversely proportional to the third angle Θ3.

[0109] With continuing reference to Figure 15rotation of the tensioning members 476, 480 in the first and second directions 524, 526, respectively, causes each of the plurality of tensioning elements 580, 582 having a fixed length to extend at a greater angle along the upper 402 (from θ1 to θ3, and from θ2 to θ4, respectively) relative to the tensioning member axis 484 and measured in each of the first and second plurality of planes, respectively. Further, in the illustrated embodiment, the interior surfaces 530, 534 of the proximal and distal tensioning members 476, 480 are fixed to at least the upper side 562 of the upper 402 and the sole aperture 560 such that the length L2 (see Figure 16 ) between the tensioning members 476, 480 is fixed. Thus, rotation of the tensioning members 476, 480 causes the first and second plurality of tensioning elements 580, 582 to be tensioned to a second tension, which pulls the lateral side 416 and the medial side 418 of the upper 402 inwardly and also pulls the instep region 458 of the upper 402 downwardly toward the sole structure 404. Further, in the illustrated embodiment, the tension from the first and second plurality of tensioning elements 580, 582 tensioned to the second tension is more evenly distributed along the upper 402 because the plurality of tensioning elements 580, 582 extend through the upper 402 in a crisscrossing manner.

[0110] Referring again to Figure 14 and Figure 15 , in some embodiments, the first angle θ1 of the first plurality of tensioning elements 580 relative to the tensioning member axis 484 and measured in each of the first plurality of planes can be inversely proportional to the second angle θ2 of the second plurality of tensioning elements 582 relative to the tensioning member axis 484 and measured in each of the second plurality of planes, or vice versa. In some embodiments, one or more tensioning elements of the first plurality of tensioning elements 580 can extend along the upper 402 at an angle relative to the tensioning member axis 484 that is less than or greater than the first angle θ1 and measured in each of the first plurality of planes. In some embodiments, one or more tensioning elements of the second plurality of tensioning elements 582 can extend along the upper 402 at an angle relative to the tensioning member axis 484 that is less than or greater than the second angle θ2 and measured in each of the second plurality of planes. In some embodiments, the ratio between the first and second angles θ1, θ2 relative to the tensioning member axis 484 and measured in each of the first and second plurality of planes, respectively, and the third and fourth angles θ3, θ4 is in the range of about 1:17 to about 10:11, in the range of about 1:13 to about 10:15, or in the range of about 1:11 to about 10:19.

[0111] It is contemplated that at least one of the proximal tensioning member 476 and / or the distal tensioning member 480 can include a fixed inner tensioning member and a rotatable outer tensioning member. Referring now to Figure 16 andFigure 17 For example, another embodiment of the fastening mechanism 470 is described. Figure 16 and Figure 17 The fastening mechanism 470 of the article of footwear 400 is similar to the aforementioned embodiments of Figures 10-15 , like elements are denoted by like reference numerals. In the embodiment shown in Figure 16 and Figure 17 , the proximal tension member 476 includes an outer tension member 590 and an inner tension member 592 disposed within the outer tension member 590, and the distal tension member 480 includes an outer tension member 594 and an inner tension member 596 disposed within the outer tension member 594. With reference to Figure 10 and Figure 16 , in the embodiment shown, the inner surfaces 530, 534 of the inner tension members 592, 596 of the proximal and distal tension members 476, 480 can be fixedly attached to at least the upper side 562 of the sole aperture 560 of the upper 402 and the sole structure 404. In this way, the outer tension members 590, 594 of the proximal and distal tension members 476, 480 can rotate in the first and second directions 524, 526 about the tension member axis 484 while the inner tension members 592, 596 remain fixed in place.

[0112] With reference to Figure 16 , the first ends 580a of the first plurality of tension elements 580 are fixedly attached to the inner tension member 592 of the proximal tension member 476, while the second ends 580b (see Figure 17 ) are fixedly attached to the outer tension member 594 of the distal tension member 480. Similarly, the first ends 582a (see Figure 17 ) of the second plurality of tension elements 582 are fixedly attached to the inner tension member 596 of the distal tension member 480, while the second ends 582b are fixedly attached to the outer tension member 590 of the proximal tension member 476. With reference to Figure 17 , with at least the distal tension member 480 in this configuration, when the fastening mechanism 470 is moved to the cinched configuration (as shown in Figure 15As shown, the second end 580b of the first plurality of tensioning elements 580 moves with the outer tensioning member 594 of the distal tensioning member 480, while the first end 582a of the second plurality of tensioning elements 582 remains stationary on the fixed inner tensioning member 596 of the distal tensioning member 480. In some embodiments, each of the inner and outer tensioning members 592, 596, 590, 594 of the proximal and distal tensioning members 476, 480 can comprise a material having elastic properties. In some embodiments, the outer tensioning members 590, 594 can comprise a first material, and the inner tensioning members 592, 596 can comprise a second material having a greater elastic modulus than the first material. In some embodiments, the inner tensioning members 592, 596 of the proximal and distal tensioning members 476, 480 can be defined at end portions of a single unitary piece that defines a tensioning member tube (not shown) extending between the inner tensioning members 592, 596. In such embodiments, the tensioning member tube can extend at least along the upper 402 of the article of footwear 400, and at least some of the plurality of tensioning elements 580, 582 can extend along an outer surface of the tensioning member tube.

[0113] Referring again to Figure 16 and Figure 17 It is contemplated that the fastening mechanism 470 can include a tension retention mechanism 540 (see Figure 14 ), which can be configured to engage at least one of the proximal and distal tensioning members 476, 480 to releasably retain the fastening mechanism 470 in the cinched configuration or one of a plurality of cinched configurations. For example, in some embodiments, the tension retention mechanism 540 of the fastening mechanism 470 can be disposed between the inner periphery of the outer tensioning members 590, 594 and the outer periphery of the inner tensioning members 592, 596 of the proximal and distal tensioning members 476, 480, which can be configured to retain the outer tensioning members 590, 594 at a desired rotational angle relative to the fixed inner tensioning members 592, 596.

[0114] In some embodiments, the tension retention mechanism 540 of the fastening mechanism 470 can be a ratchet system including a plurality of teeth arranged along at least one of the inner surfaces 530, 534 of the proximal and / or distal tensioning members 476, 480, and one or more pivoting pawls arranged on the upper side 562, proximal side 564, and / or distal side 566 of the sole aperture 560 configured to releasably engage the plurality of teeth of the proximal and / or distal tensioning members 476, 480. In such embodiments, the one or more pivoting pawls of the ratchet system can be pivoted by one or more actuators, such as a lever or button 546, which can be arranged on the lateral side 416 and / or medial side 418 of the upper 402 or sole structure 404 of the article of footwear 400 and can be configured to simultaneously pivot two or more pawls such that the proximal and / or distal tensioning members 476, 480 are simultaneously released from the cinched configuration. In some embodiments, the ratchet system can include a plurality of teeth arranged along the outer surfaces 528, 532 of the proximal and / or distal tensioning members 476, 480, respectively, and one or more pivoting pawls arranged on the lower side of the sole aperture configured to releasably engage the plurality of teeth of the proximal and / or distal tensioning members 476, 480. In such embodiments, the one or more pivoting pawls of the ratchet system can be pivoted by one or more actuators, such as a lever or button 546, which can be disposed on the lateral side 416 and / or medial side 418 of the upper 402 or sole structure 404 of the article of footwear 400 and / or the bottom surface 466 (see Figure 11 ) of the sole structure 404.

[0115] In some embodiments, the tension retention mechanism 540 of the fastening mechanism 470 can include a plurality of protrusions extending outwardly from the upper 402 configured to be received by one or more openings or grooves disposed on at least one of the inner surfaces 530, 534 of the proximal and / or distal tensioning members 476, 480, or vice versa. In some embodiments, the tension retention mechanism 540 can include a plurality of hooks and a plurality of loops, i.e., a corresponding male and female side of Velcro. In such embodiments, and with reference to Figure 15 , the plurality of hooks can be arranged along at least one of the inner surfaces 530, 534 of the proximal and / or distal tensioning members 476, 480 adjacent the proximal and / or distal protrusions 570, 586, respectively, and the plurality of loops can be arranged along the instep region 458, lateral side 416, and / or medial side 418 of the upper 402 of the article of footwear 400 adjacent the location of the proximal and / or distal tensioning members 476, 480. In such embodiments, and still with reference to Figure 15, the proximal and / or distal tensioning members 476, 480 can be configured to elastically expand when the proximal and / or distal protrusions 570, 586 are pulled outward by the user, respectively, such that the plurality of hooks on the inner surfaces 530, 534 disengage from the first portion of the plurality of loops of the upper 402, rotate in the first direction 524 to the tightening configuration and / or in the second direction 526 to the loosening configuration, and re-engage the second portion of the plurality of loops on the upper 402.

[0116] Reference is made to Figures 4-17 , the various components of the example articles of footwear 200 and 400 can be formed by additive manufacturing techniques, such as by one or more of the various 3D printing techniques described above. For example, in some embodiments, the various tensioning members 272, 472 of the fastening mechanisms 270, 470 can be 3D printed as a single integral piece. In other embodiments, the inner tensioning member 280 of the fastening mechanism 270 can be 3D printed separately from the outer tensioning member 276, and then the inner tensioning member 280 can be disposed within the outer tensioning member 276.
