Description

[0001] Related applications

[0002] This application is a divisional application of the invention patent application filed on February 21, 2020, with application number 202080015942.0 (international application number PCT / US2020 / 019362) and entitled "Footwear Article with Abrasion-Resistant Protective Components". Background Technology

[0003] Footwear can be subjected to significant stress throughout its use, leading to deterioration over time. Different areas of the footwear may deteriorate at different rates depending on the specific activities the user engages in. For example, in construction, repair work, and other related fields, users may frequently perform knee-bending movements, lunges, squats, and other actions that cause frequent flexion at the vamp. Similarly, other activities such as hiking and various sports can also cause frequent flexion at the vamp. This frequent flexion at the vamp is problematic because it can lead to rapid deterioration of the vamp, particularly where it meets the quarter.

[0004] For example, substantial deterioration (including the formation of holes) may occur near the junction of the vamp and the instep of the footwear. Therefore, deterioration is concentrated at the vamp compared to the rest of the footwear. Summary of the Invention

[0005] Therefore, considering the above circumstances, the inventors have developed a footwear article that at least partially solves the aforementioned problems. Specifically, the inventors have developed a footwear article comprising a flexible abrasion-resistant forefoot guard positioned at the forefoot of the footwear article. It should be noted that the flexible abrasion-resistant forefoot guard may also be referred to herein as an abrasion guard or a forefoot abrasion guard.

[0006] In at least one example, the flexible fore-upper abrasion protection element may be formed as a cover located above the upper of the footwear article. However, in one or more examples, the flexible fore-upper abrasion protection element may be integrated with the upper of the footwear article. The flexible fore-upper abrasion protection element may be formed as a corrugated tube including grooves and ribs to ensure structural support and flexibility. Furthermore, the flexible fore-upper protection element may be integrated with the toe cap of the footwear article.

[0007] With the flexible abrasion-resistant forefoot protection as described above, the force applied to the footwear by bending at the forefoot can be distributed throughout the abrasion-resistant protection, thereby preventing the footwear from deteriorating. Furthermore, the flexibility of the flexible forefoot protection ensures sufficient flexibility for the user's comfort and freedom of movement. Attached Figure Description

[0044] The following description relates to a footwear article that includes abrasion-resistant protective components to prevent deterioration of the forefoot while maintaining the flexibility and mobility of the footwear for the user's comfort.

[0045] like Figures 1-9 And Figures 11, 14, 20, 24, and 27. Figure 30 As shown in Figure 31, footwear articles may include a flexible abrasion protection feature at the forequarter. This flexible abrasion protection feature can be a cover formed using a corrugated tube comprising ribs and grooves. The corrugated tube provides force dispersion to prevent deterioration of the footwear article while also allowing the footwear article to bend at the forequarter. The corrugated tube may include, for example... Figures 10A-10F Various outlines are shown.

[0046] Corrugated pipe fittings have various shapes and various configurations (such as...) Figure 13 Figures 16-19, 22-23 Figure 26 , Figure 29 (As shown in Figures 33-35) is feasible. In one or more examples, such as Figures 1 to 9As shown in Figures 12, 15, 21, 25, 28, and 32, the corrugated tubular feature can be integrated into the heel of footwear. In this way, flexing can be achieved while preventing deterioration of the footwear. In one or more embodiments, the flexible abrasion protection element with corrugated tubing can be integrated with other abrasion protection components to improve the force distribution and strength of the abrasion protection. For example, the flexible abrasion protection element can be integrated with one or more of the toe cap, heel cap, and peripheral abrasion protection components.

[0047] Figures 1-3 Figure 5 illustrates the relative positioning of the various components of a footwear item. If a component is shown to be in direct contact or directly joined to another, then in at least one example such a component may be referred to as being in direct contact or directly joined, respectively. Similarly, components shown to be continuous or adjacent to each other may be continuous or adjacent to each other, respectively, in at least one example.

[0048] As an example, components that are in contact with each other on the same plane can be referred to as being in contact with each other on the same plane or in physical contact. As another example, elements that are positioned separately from each other and have only space between them without other components can be referred to as being separated from each other in at least one example.

[0049] As another example, elements shown as being above / below each other, on opposite sides of each other, or on the left / right of each other may be referred to as being above / below, on opposite sides, or on the left / right of each other relative to each other. Furthermore, as shown in the figures, the topmost element or the topmost point of an element may be referred to as the “top” of the component in at least one example, and the bottommost element or the bottommost point of an element may be referred to as the “bottom” of the component in at least one example. As used herein, top / bottom, upper / lower, above / below may be relative to the vertical axis of the figures and may be used to describe the positioning of the elements in the figures relative to each other. Thus, an element shown above other elements is vertically positioned above said other elements in one example. As another example, the shapes depicted in the figures of elements may be referred to as having those shapes (e.g., such as circular, straight, planar, curved, arcuate, chamfered, angled, etc.). Furthermore, elements shown as being adjacent to each other may be referred to as adjacent elements or adjacent to each other in at least one example. Furthermore, an element shown as being inside or outside another element may be referred to as being inside or outside said other element in one example.

[0050] Furthermore, while various example footwear items are used to illustrate the features, it should be noted that features on various footwear items described herein can be combined. For example, multiple corrugated tubular profiles and shapes may be included in the same footwear item. Therefore, an illustration of one footwear item does not exclude features included in other footwear items shown herein. More precisely, the features of the various footwear items are interchangeable and combinable.

[0051] For discussion purposes, we will jointly describe Figure 2-Figure 1 4.

[0052] Figure 1 A first side view of a first example footwear article 100 according to one or more embodiments of the present disclosure is shown.

[0053] In one or more examples, the first example footwear item may be a work boot. However, it should be noted that footwear item 100 is not limited to work boots, and the features of footwear item 100 discussed herein are applicable to other types of footwear items. Additionally, the features of other example footwear items described herein (which may be schematically shown as work boots) are also applicable to other types of footwear items. These different types of footwear items may include casual shoes, sandals, various athletic shoes, and other types of boots.

[0054] The first example footwear article may include an abrasion-resistant protective element made of a material different from the material of the upper of the first example footwear article, which is generally indicated by 201. The upper 201 may include a forefoot 206 (including a toe cap joint 206a and a midfoot joint 206b) and a side section formed by a first midfoot panel 234 and a second midfoot panel 235. It should be noted that the first midfoot panel and the second midfoot panel may also be referred to herein as a first midfoot panel and a second midfoot panel, respectively. However, in other examples, the upper of the footwear article may not include a panel structure. For example, instead, the upper may be a one-piece upper or an upper with an interchangeable panel arrangement.

[0055] In at least one example, the abrasion-resistant protective component may include any one of natural rubber, vulcanized rubber, ethylene vinyl acetate (EVA), polyvinyl chloride (PVC), polyurethane (such as thermoplastic polyurethane (TPU)), and other materials with similar properties. It should be noted that any protective component described herein, including corrugated tubular structures or grooved structures only, may include one or more of these materials. Regarding the upper, any upper of the example footwear articles described herein may include any one or a combination of moldable materials, leather, synthetic leather, knitted textiles, nylon, and other materials with similar properties.

[0056] The abrasion-resistant protective element can be specifically shaped and positioned to protect the upper while also being sufficiently flexible at the forefoot 210 to ensure user comfort. Specifically, the abrasion-resistant protective element can be positioned and shaped to facilitate comfortable knee flexion movements and other movements that cause forefoot bending by the user wearing the first example footwear while reducing material wear and deterioration.

[0057] The abrasion protection structure may include one or more components, including one or more of a flexible forefoot abrasion protector 202, a toe cap 204, a heel cap 208, and a perimeter 222. It should be noted that in one or more examples, the flexible forefoot abrasion protector 202 may be formed as a cover. Therefore, the flexible forefoot abrasion protector 202 may also be referred to herein as a flexible forefoot cover or abrasion protector. Furthermore, the heel cap 208 may also be referred to herein as a heel protector.

[0058] In at least one example, the components of the wear protection structure may be molded. In some examples, the wear protection structure may be a single molded part. However, in other manifestations, the components of the wear protection structure may be molded separately and then joined together.

[0059] One or more components of the abrasion protection structure can be directly molded to the upper of the footwear article. Alternatively or additionally, one or more components of the abrasion protection structure can be formed and then attached to the upper of the first example footwear article. For example, at least one component of the first example footwear article can be molded and then bonded to the upper using an adhesive. It should be understood that other attachment methods (such as stitching or ultrasonic welding) for bonding one or more components of the abrasion protection to the upper are also feasible.

[0060] A flexible, abrasion-resistant forefoot protector 202, which can be formed from a corrugated tubing, is positioned at the forefoot 210 of the footwear article. The forefoot 210 may be located at the toe 212 of the first example footwear article and at the first instep 234 and second instep 235 of the first example footwear article. Figure 3 and Figure 4 The area extending between the second shoe waist 235 shown in the figure. Specifically, the forefoot 210 extends along the lace line of the footwear article on the toe side of the lace line. The forefoot 210 includes the metatarsophalangeal joint area 101 of the footwear article (see figure). Figure 2 The metatarsophalangeal joint region 101 is the curved area on the toe side of footwear adjacent to the lace line.

[0061] The flexible front abrasion-resistant protective component 202 has a corrugated tubular structure, wherein the corrugated tubular structure of the flexible front abrasion-resistant protective component 202 includes pleats. The pleats of the corrugated tubular structure can be formed by ribs 202a and grooves 202b of the corrugated tubular structure (described in further detail below). The pleats of the corrugated tubular structure can advantageously achieve both unfolding and bending.

[0062] Therefore, the corrugated tubular structure of the flexible forefoot abrasion protector 202 allows it to unfold and bend at the flexion point of the user's foot. Specifically, during use, the corrugated tubular portion of the flexible forefoot abrasion protector 202 can be positioned at the metatarsophalangeal joint area (basically at the ball of the foot of the user's foot). The metatarsophalangeal joint is the flexion point during the user's knee-bending movements, lunges, squats, and other similar movements. Therefore, because the flexible forefoot abrasion protector 202 allows flexion at the metatarsophalangeal joint during use and is shaped to move with the user during use, it prevents deterioration of footwear while achieving user comfort.

[0063] The metatarsophalangeal joint area 101 of footwear is the area on the toe side of the shoelaces that is immediately adjacent to the shoelaces of the footwear.

[0064] Continuing with footwear items, in at least one example, such as Figure 2 As shown, the first shoe upper 234 and the second shoe upper 235 may include structures for holding shoelaces 226 in footwear. For example, the first shoe upper 234 and the second shoe upper 235 may include one or more eyelets 230 for receiving shoelaces 226. Furthermore, each of the first shoe upper 234 and the second shoe upper 235 may include a notch 216 to guide shoelaces 238. Additionally or optionally, the first shoe upper 234 and the second shoe upper 235 may include hooks 228 for receiving shoelaces 226. It should also be noted that in at least one example, the footwear may not include shoelaces. Furthermore, the upper of the footwear may include replaceable sheet arrangements, straps, or one-piece constructions.

[0065] The first shoe waist 234 and the second shoe waist 235 form the side of the first example footwear article and are part of the upper 201. As shown, the first shoe waist 234 and the second shoe waist 235 are sheets of material extending from the outsole 218 of the first example footwear article to the tongue 232. The outsole 218 may form the bottom surface of the first example footwear article. The sheets of material (e.g., the first shoe waist 234 and the second shoe waist 235) may include one or more sheets. Stitching 238 may be included to bind multiple sheets of material together and / or provide a reinforcing effect throughout the first shoe waist 234 and the second shoe waist 235. For example, stitching 238 may also be included at the lacing structure.

[0066] For example, the first shoe waist 234 may include a lateral support seam 238a, wherein the lateral support seam 238a includes a seam from the front edge 234a of the first shoe waist 234 to the heel edge 234b of the first shoe waist 234. The front edge 234a of the first shoe waist material is the edge of the first shoe waist material 234 closest to the toe 212 of the first example footwear article. The heel edge 234b of the first shoe waist material 234 is the edge of the first shoe waist material 234 closest to the heel of the first example footwear article. In at least one example, the lateral support seam 238a may include multiple rows of seams. For example, the lateral support seam 238a may include three rows of seams.

[0067] Next, the first shoe waist panel 234 may also include a peripheral seam 238b. The peripheral seam 238b may be a seam that is substantially located at and runs along the edge of the panel. For the first shoe waist panel 234, this peripheral seam 238b may be substantially located at one or more edges of the first shoe waist panel 234 and extend along those edges. For example, the first shoe waist panel 234 may include peripheral seams 238b located at any one or more of the front edge 234a, the tongue edge 234c, and the upper edge 234d of the first shoe waist panel 234. In at least one example, the peripheral seam 238b may include multiple rows of seams. Additionally, in one or more examples, the number of rows of the peripheral seam 238b may vary along the edge of the same panel.

[0068] For example, for approximately the first half of the front edge 234a, the front edge 234a of the first shoe waist 234 may include three rows of peripheral seams 238b, wherein the first half of the front edge 234a is closer to the outsole 218 than the second half of the front edge 234a. For approximately the second half of the front edge 234a, the front edge 234a of the first shoe waist piece may also include two rows of peripheral seams 238b, wherein the second half of the front edge 234a is closer to the tongue 232 than the first half of the front edge 234b. Therefore, the number of rows of peripheral seams 238b on the same edge of the same piece of material may be different.

[0069] The variation in the number of rows of peripheral seam 238b at the same edge can specifically benefit from altering the support along the same edge. For example, the first half of the front edge 234a, comprising three rows of peripheral seam 238b, can have stronger support than the second half of the front edge 234a, which comprises two rows of peripheral seam 238b.

[0070] Alternatively or additionally, it should be understood that the same number of rows of peripheral seams 238b can be used along the entire edge of the sheet material. For example, two rows of peripheral seams 238b can be used along the tongue edge 234c of the first instep 234. In one or more examples, for the same sheet material, the number of rows of peripheral seams 238b can vary from one edge to another. For example, the first edge can have two rows of peripheral seams 238b for the entire first edge, and the second edge can have three rows of peripheral seams 238b for the entire second edge. Furthermore, in one or more embodiments, the same number of rows of peripheral seams 238b can be used along all edges of the sheet material. It should be noted that in examples where the upper can be a one-piece upper, can include different sheet material arrangements, or can have stripes, different peripheral seams or no peripheral seams may be used.

[0071] Alternatively or additionally, for the shoe seam construction, the first shoe waist 234 may include a lace-reinforced seam 238c. The lace-reinforced seam 238 may be positioned such that one or more lace-receiving structures (hooks 228, eyelets 232, notches 216) are positioned between the lace-reinforced seam 238c and the edge 234c of the tongue. This lace-reinforced seam 238 may extend the length of the first shoe waist 234 from a peripheral seam 238b located at the upper edge 234d of the first shoe waist 234 to a peripheral seam 238b located at the front edge 234a of the first shoe waist 234. The lace-reinforced seam 238c may help protect the first shoe waist 234 from deterioration due to the tension of the laces 226. However, in other examples, the footwear article may not include laces, and therefore the footwear article may not include a lace-reinforced seam.

[0072] In addition to the above, the shoe tongue 232 may be positioned between the first shoe waist 234 and the second shoe waist 235, wherein the shoe tongue 232 at least partially overlaps with the first shoe waist 232 and the second shoe waist 235. (See also: Regarding...) Figure 2 As described, the shoe tongue 232 may include an upper portion 232a and a lower portion 232b.

[0073] In at least one example, the first shoe support 234 and the second shoe support 235 may both be integrated into the ankle support 224, wherein, in one or more examples, the ankle support 224 may include padding for user comfort. For example, the ankle support 224 may further advantageously provide a tighter fit to prevent debris from entering.

[0074] In one or more examples, the flexible forefoot abrasion protection 202 may be positioned on the top of the upper. For example, the forefoot portion 206 of the upper 201 may be partially covered by the flexible forefoot abrasion protection 202. The forefoot portion 206 may include a toe cap joint portion 206a and a midfoot joint portion 206b.

[0075] The toe cap joining portion 206a may engage with the toe cap 204 and the flexible forefoot abrasion protection 202, and the toe cap joining portion 206a is positioned in a gap 214 formed between the toe cap 204 and the flexible forefoot abrasion protection 202. The midsole joining portion 206b may engage with the flexible forefoot abrasion protection 202 at the midsole (e.g., a first midsole 234 and a second midsole 235). However, in one or more examples where the footwear article includes a one-piece upper rather than a sheet structure, the flexible forefoot abrasion protection 202 may be positioned at the forefoot to prevent forefoot degradation. Alternatively, in another embodiment, the flexible forefoot cover 202 may be integrally integrated into the upper, rather than located on top of the upper 201. The flexible forefoot cover 202 may be formed using corrugated tubing and thus include one or more ribs 202a and one or more grooves 202b (also referred to herein as lateral grooves). One or more grooves 202b are recessed relative to one or more ribs 202a.

[0076] One or more ribs 202a and one or more grooves 202b forming the corrugated tube increase the flexibility at the forefoot 210 while protecting the upper 201 from deterioration. The material of the flexible forefoot abrasion protection 202 can be thinner at one or more grooves 202b than at one or more ribs 202a, thus allowing the flexible forefoot cover 202 to bend more easily at one or more lateral grooves 202b. Furthermore, ribs 202a that are thicker than the grooves 202b of the flexible forefoot cover 202 can help prevent deterioration of the upper 201 by dispersing the forces generated by bending at the forefoot 210.

[0077] In at least one example, the end width of each rib 202a at any end of each rib 202a may be wider than its center. In other words, each rib 202a widens at any end adjacent to the periphery 222 and / or the outsole 218. Thus, the central portion of each rib 202a is narrower in width than its ends, wherein the central portion of each rib 202a is the portion of the rib 202a aligned and positioned between the lacing structure of the footwear article and the toe cap 204. Furthermore, the central portions of the ribs 202a and the grooves 202b are substantially parallel to each other.

[0078] By making the width of each rib 202a narrower at its central portion than at its ends, the flexible fore-upper cover 202 achieves greater flexibility in the center of the fore-upper, a common bending area in footwear. Therefore, improved user comfort and mobility can be achieved while still preventing deterioration of the footwear.

[0079] Besides the width of rib 202a varying along its length, each rib 202a can have a different curvature. For example, as Figure 1 As shown, the front edge 202c of the rib 202a closest to the toe cap 204 may be substantially perpendicular to the perimeter 222 and / or the outsole 218. It should be noted that the front edge 202c of each rib 202a refers to the edge of each rib 202a closest to the toe of the footwear item. The closer the rib 202a is to the heel cap 208, the smaller the angle formed between the front edge 202c of each rib 202a and the perimeter 222 and / or the outsole 218.

[0080] Furthermore, the closer the rib 202a is to the heel cap 208, the greater the angle formed between the rear edge 202d of each rib 202a and the periphery 222 of the corrugated tube and / or the outsole 218. It should be noted that the rear edge 202d of each rib 202a refers to the edge of each rib 202a closest to the heel of the footwear item.

[0081] The rib 202a having the aforementioned curvature helps ensure that the entire flexible front cover 202 bends, so that the flexible front cover 202 bends with the user as the user moves.

[0082] In addition to the flexible forefoot cover 202, the abrasion protection structure also includes a toe cap 204. The toe cap 204 is positioned at the toe of the first example footwear article. In at least one example, the toe cap 204 may be positioned on top of the cover 201 of the footwear article. However, in other examples, the toe cap 204 may be integrated with the upper 201, rather than positioned on top of the upper 201.

[0083] The toe cap 204 is advantageously shaped to extend further into the footwear at the user's big toe position. This shaping advantageously provides additional protection at the big toe position. The toe cap 204 also advantageously prevents the footwear from deteriorating due to wear, moisture, and debris at the toe 212.

[0084] Furthermore, the toe cap 204 can be connected to the flexible fore-upper protection 202, which is also referred to herein as an abrasion-resistant protection element. Therefore, the toe cap 204 and the flexible fore-upper protection 202 can form an integrated structure. That is, the toe cap 204 and the flexible fore-upper protection 202 are a single, integral structure. This integration of the toe cap 204 with the flexible fore-upper cover 202 provides the advantage of improved support and durability of the upper 201. While the flexible fore-upper protection 202 can be formed using corrugated tubing, it should be noted that the toe cap 204 may not be formed without corrugated tubing.

[0085] The first example footwear also includes a gap 214 (such as) located between the toe cap 204 and the flexible forefoot protection 202. Figure 1 (as shown in the diagram). Specifically, the gap 214 may be defined by the toe cap 204 and the flexible forefoot cover 202, and the entire periphery of the gap 214 is formed by the toe cap 204 and the flexible forefoot cover 202.

[0086] At the same location indicated as the transition from the toe cap 212 to the forefoot vamp 210 of the footwear article, the toe cap 204 transitions to the flexible forefoot vamp protector 202. Therefore, the gap 214 can be completely surrounded by the toe cap 204 and the flexible forefoot vamp cover 202. The forefoot vamp portion 206 of the upper 201 can be positioned within and exposed through the gap 214. Specifically, the toe cap joining portion 206a of the upper 201 can be positioned within and exposed through the gap 214. Therefore, due to the gap 214, the forefoot vamp portion 206 of the upper 201 located within the gap 214 forms part of the outer surface of the footwear article. Specifically, the toe cap joining portion 206a is positioned within the gap 214 and forms part of the outer surface of the footwear article.

[0087] Since degradation typically concentrates in the area of ​​the forefoot adjacent to the instep, gap 214 can strategically create an abrasion-resistant structure to protect the upper 201 at the most vulnerable location. This strategic approach to protecting the upper advantageously provides protection against degradation while avoiding unnecessary overuse of materials.

[0088] Furthermore, including gap 214, compared to fully covering the forefoot and toe box, further contributes to reducing the overall weight of footwear. This weight reduction helps improve overall user comfort.

[0089] In addition to the toe cap 204, further toe protection can be provided by a toe reinforcement structure. For example, footwear articles may include a toe reinforcement structure located below the upper 201 at the toe of the footwear article. The toe reinforcement structure may include steel or a composite material such as carbon fiber, dense plastic, or Kevlar. However, in other examples, the footwear article may not include a toe reinforcement structure.

[0090] In one or more examples, the abrasion protection structure may also include a heel cap 208 positioned at the heel of the first example footwear article. The heel cap 208 may include ribs 208a for increasing structural support. However, in at least one example, the heel cap 208 may be more rigid than the flexible forefoot abrasion protector 202. For example, the thickness of the heel cap 208 may be greater than the thickness of the flexible forefoot abrasion protector. Therefore, although the heel cap 208 includes ribs 208a similarly to the flexible forefoot abrasion protector 202, it should be noted that the heel cap 208 does not have the same structure as the flexible forefoot abrasion protector 202, and the heel cap 208 may achieve less flexibility than the flexible forefoot abrasion protector 202.

[0091] In at least one embodiment, the heel cap 208 may be positioned on top of the upper 201 of the footwear article. However, it should be understood that, alternatively, the heel cap 208 may be integrated into the upper 210.

[0092] The heel cap 208 can be connected to the flexible forefoot cover 202 via the periphery 222 of the abrasion protection structure. For example, the heel cap 208 can be connected to the flexible forefoot cover 202 via the periphery 222 of the abrasion protection structure. Therefore, the heel cap 208, the flexible forefoot cover 202, and the toe cap 204 can be an integral structure.

[0093] By connecting the heel cap 208, the flexible forefoot cover 202, and the toe cap 204 via the perimeter 222, the abrasion protection structure can effectively disperse forces to prevent deterioration of the upper 201. Furthermore, by forming the heel cap 208, the flexible forefoot cover 202, and the toe cap 204 into an integrated structure, improved structural stability of the abrasion protection structure itself can be achieved.

[0094] In at least one example, the periphery 222 of the abrasion protection structure may be a component positioned along the entire periphery of the footwear article or substantially the entire periphery of the footwear article. The periphery 222 of the abrasion protection structure may be positioned between the outsole 218 and the upper 201.

[0095] In at least one embodiment, the periphery 222 of the abrasion protection structure may be positioned on a portion of the outsole 218 and a portion of the upper 201. In at least one example, the outsole 218 may include a tread 220. The periphery 222 may advantageously prevent deterioration of the footwear at the junction of the upper 201 and the outsole.

[0096] In addition to connecting other components of the abrasion protection structure to improve force distribution and thus prevent deterioration of the upper 201, the periphery 222 of the abrasion protection structure can also advantageously improve the bonding between the upper 201 and the outsole 218.

[0097] Now go to Figure 2The image shows the front view of the first example footwear item 200. (See image for details.) Figure 2 As shown, the shoe tongue 232 includes an upper portion 232a and a lower portion 232b. In at least one example, the upper portion 232a of the shoe tongue 232 may be padded for the user's comfort and grip.

[0098] The lower portion 232b of the tongue 232 may include a lace guide 233 for positioning the laces 226. Furthermore, the flexible forefoot abrasion protection 202 may include an extension 306 extending onto the lower portion 232b of the tongue 232. The extension 306 may advantageously help to further distribute forces and prevent deterioration of the upper 201. In at least one example, the extension 306 may be rounded to ensure user comfort and prevent deterioration of the forefoot upper.

[0099] The extension 306 may be positioned between the first shoe instep 234 and the second shoe instep 235. In at least one example, the extension 306 may be positioned such that the extension 306 does not contact the first shoe instep 234 and the second shoe instep 235. The extension 306 may also be positioned such that at least a portion of the extension 306 is positioned below the shoelace 226.

[0100] The extension 306, comprising an extension located on the lower portion 232b of the tongue 232 and at least partially below the laces 226, not only serves to disperse forces to prevent deterioration of the upper 201 but also advantageously provides structural rigidity to prevent wrinkling and deterioration of the tongue 232. The extension 306 may be formed adjacent to the metatarsophalangeal joint region 101 of the footwear.

[0101] Extension 306 can also be formed using corrugated tubing. Therefore, similar to the flexible fore-upper cover 202, extension 306 may also include ribs 202a and grooves 202b. However, the ribs 202a and grooves 202b of the corrugated tubing of extension 306 may be spaced further apart than the spacing between the ribs 202a and grooves 202b along the fore-upper part 210 of the footwear. That is, the distance between the ribs 202a and grooves 202b of the corrugated tubing of the flexible fore-upper abrasion protection 202 may be smaller than the distance between the ribs 202a and grooves 202b of the corrugated tubing of extension 306.

[0102] The further spacing between the ribs 202a and the grooves 202b at the extension 306 allows the extension 306 to bend in a manner that mimics a user's knee-bent, lunge, squatting, or other similar positions. That is, for example, when the user is in a knee-bent position, less bending is required at the lower portion 232b of the tongue 232 than at the forefoot 210. Therefore, the ribs 202a and grooves 202b of the corrugated tube of the extension 306 are further apart at the lower portion 232b of the tongue 232 than at the forefoot 210 to accommodate such user movement while still providing as much support as possible.

[0103] Briefly Figures 10A-10F It should be noted that example outlines for corrugated fittings (such as the corrugated fitting for the first example footwear item) are shown. First, go to... Figure 10A The first example of a corrugated tube profile 1000 is shown. Figure 10A As shown, for the first example corrugated profile 1000, there are valleys 1006 and peaks 1008. Peaks 1008 are relatively sharp, and valleys 1006 located between successive peaks 1008 are arc-shaped. The thickness of the material used for the first example corrugated profile 1000 is substantially constant. This construction allows for the achievement of bellows durability while still permitting bending. Although the first example corrugated profile 1000 can be used with any one or any combination of the example corrugated profiles discussed herein, it should be noted that in at least one example, the corrugated profile can be used with... Figures 1-9 The example footwear items in the text are used in combination.

[0104] Go to Figure 10B The second example of a corrugated tubular profile 1001 is shown. Figure 10B As shown, the second exemplary corrugated profile 1001 includes notches 1010 but not arcuate valleys. Each notch 1010 advantageously includes a first movable hinge point 1012 and a second movable hinge point 1014, such that when the peaks 1008 of the second exemplary corrugated profile 1001 undergo bending (as indicated by the bend line 1016), the peaks 1008 of the corrugated profile are more likely to align with each other as indicated by arrow 1018. It should be noted that in at least one example, bending may occur in a bent position. While the second exemplary corrugated profile 1001 can be used with any one or any combination of the exemplary corrugated profiles discussed herein, it should be noted that in at least one example, the corrugated profile can be used in conjunction with the exemplary footwear articles in Figures 11-13.

[0105] Now go to Figure 10C , Figure 10C A third example of a bellows-shaped profile 1002 is shown. This third example of a bellows-shaped profile 1002 is also undergoing a bend, as shown by the bend line 1016. Figure 10CAs can be seen, the third example corrugated profile 1002 includes varying thicknesses through thinning valleys 1020. That is, the thinning valleys 1020 are relatively thinner compared to the thickness of the corrugated member at the peak 1008 and the thickness of the wall 1022 extending between the peak 1008 and the valley 1020. Furthermore, for example, the thinning valleys 1020 are relatively wider compared to the second example corrugated profile 1001. Through the thinning valleys 1020, the corrugated member can be easily bent toward each other during bending, as indicated by arrow 1018. While the third example corrugated profile 1002 can be used with any one or any combination of the example corrugated members discussed herein, it should be noted that in at least one example, the corrugated profile can be compared with that in Figure 11- Figure 13 The example footwear items in the text are used in combination.

[0106] Now go to Figure 10D , Figure 10D A fourth example of a bellows profile 1003 is shown. The fourth example of a bellows profile 1003 forms raised strips 1024 (also referred to herein as peaks) and a capsule shape to provide flexibility and structural properties. The raised strips 1024 are the peaks of the fourth example of the bellows profile 1003, and sharp valleys 1026 are formed between successive raised strips 1024. When bent, the valleys 1026 are able to move, while the raised strips 1024 provide rigidity and structural properties. While the fourth example of a bellows profile 1003 can be used with any one or any combination of the example bellows components discussed herein, it should be noted that in at least one example, the bellows profile can be used with Figure 24- Figure 26 The example footwear items in the text are used in combination.

[0107] Now go to Figure 10E , Figure 10E A fifth example of a corrugated profile 1004 is shown. The fourth example of a corrugated profile 1004 includes relatively thin hollow ribs 1030 to form the peaks of the profile and wide valleys 1028. The cross-section of the thin hollow ribs 1030 is approximately C-shaped. This thin hollow rib 1030 and wide valleys 1028 can be a more flexible corrugated profile compared to the other profiles discussed herein. While the fifth example of a corrugated profile 1004 can be used with any one or any combination of the example corrugated pipes discussed herein, it should be noted that in at least one example, the corrugated profile can be used with that shown in Figure 27- Figure 29 The example footwear items in the text are used in combination.

[0108] Looking at it now Figure 10F , Figure 10FA sixth example of a corrugated tubular profile 1005 is shown in a flexed position 1032, a flat position 1034 (also referred to herein as the base position), and an extended position 1036. It should be noted that the flexed position 1032 may occur during flexion in the metatarsophalangeal joint region of the footwear (e.g., when walking or during a knee-flexed position). The flat position 1034 may occur in areas of the footwear with small curvature. The extended position 1036 may occur when it is necessary to extend the corrugated tubing over the forefoot of the user. That is, extension can be an extension of the corrugated tubing from the outsole at the inner step of the footwear to the outsole at the outer step of the footwear. It should be noted that in at least one example, the sixth example of a corrugated tubular profile 1005 corresponds to the grid corrugated tubular construction shown in Figures 14-19. The sixth example of a corrugated tubular profile 1005 includes quadrilaterals 1038 spaced apart by valleys 1040 to form a grid. In the bent position 1032, quadrilaterals 1038 bend towards each other across valley 1040, and the quadrilaterals themselves bend inward. Due to the inward bending of quadrilaterals 1038, the top surface of the quadrilaterals bends similarly to the curved curve 1042. In the flat position 1034, quadrilaterals 1038 are substantially flat at their top surfaces. In the extended position 1036, the top surface of the quadrilaterals unfolds and bends in the opposite direction to that during bending 1032. This is particularly due to the formation of voids in quadrilaterals 1038 (discussed in more detail in Figures 18-19). The ability of quadrilaterals 1038 to bend in the processing direction (collapse during bending and unfold during extension) improves flexibility while maintaining the integrity of the footwear article. While the sixth example corrugated profile 1004 can be used with any one or any combination of the example corrugated fittings discussed herein, it should be noted that in at least one example, the corrugated profile can be used in conjunction with the example footwear articles of Figures 14-17. In addition to the example profile shown, it should be noted that other profiles are envisioned. For example, a profile in which both the peak and valley have roughly V-shaped cross-sections is feasible.

[0109] Now back Figure 1 It should be noted that flexible abrasion-resistant front guards 202, including any one or any combination of the contours discussed herein, achieve many advantages. For example, by including at least the metatarsophalangeal joint area covering the front guard 210 (see... Figure 2 The flexible abrasion protection element 202 (101) prevents the upper 201 from deteriorating at the forefoot 210 because the force can be distributed throughout the abrasion protection element. Furthermore, the inclusion of an extension (e.g., extension 306) from the flexible abrasion protection element 202 to the lower part of the tongue 232b further helps to prevent deterioration.

[0110] continue Figure 2As further shown, the flexible forefoot cover 202 may include a first curve 302 along the first instep 234 and a second curve 304 along the second instep 235.

[0111] The first curve 302 and the second curve 304 can respectively facilitate the accommodation of the first shoe waist 234 and the second shoe waist 235, so as to prevent the first shoe waist 234 and the second shoe waist 235 from deteriorating due to friction.

[0112] In other words, friction between the first shoe corset 234 and the second shoe corset 235 and the flexible forefoot abrasion-resistant protective element 202 may cause damage to the upper 201 at the first shoe corset 234 and the second shoe corset 235. Therefore, shaping the flexible overlay 202 to include the first curve 302 and the second curve 304 can help avoid such degradation because it minimizes or prevents contact.

[0113] like Figure 2 As further shown, the flexible front fender 202 is substantially symmetrical. Therefore, the second curve 304 of the flexible front fender 202 substantially reflects the shape of the first curve 302 of the flexible front fender 202.

[0114] The first curve 302 of the flexible forefoot protector 202 curves continuously and transitions to the extension 306 (including the highest point 305 of the extension 306). Similarly, the second curve 304 of the flexible forefoot protector 202 also curves continuously and transitions to the extension 306 (including the highest point 305 of the extension 306). The continuous curvature of the transition area between the flexible forefoot protector 202 and the extension 306 at the first curve 302 and the second curve 304 advantageously improves user comfort while preventing deterioration of the shoe upper.

[0115] Go to Figure 3 , Figure 3 A second side view of a first example footwear item 300 is shown. (As can be seen from...) Figure 3 As seen in the image, the ribs 202a and grooves 202b of the flexible abrasion-resistant fore-end guard 202 are shaped to have substantially the same shape and size on the second side of the first example footwear article as on the first side. Furthermore, it is possible to... Figure 3 The second shoe waist 235 can be observed more clearly in the image. It should be noted that the front edge 235a, heel edge 235b, tongue edge 235c, and upper edge 235d of the second shoe waist 235 correspond to the front edge 234a, heel edge 234b, tongue edge 234c, and upper edge 234d of the second shoe waist 234. Details regarding the edges, seams, and lacing structure of the first shoe waist 234 similarly apply to the second shoe waist 235 and will not be discussed further herein.

[0116] Reference Figures 1-3 As can be clearly seen, the abrasion-resistant protective element 202 extends from the outsole 218 located on the first side of the footwear to the outsole 218 located on the second (opposite) side of the footwear. Specifically, the abrasion-resistant protective element 202 extends from the inner step side of the outsole 218 to the outer step side of the outsole, and extends across the vamp 210 and the metatarsophalangeal joint area 101 of the footwear. In at least one example, the abrasion-resistant protective element 202 may be integrated between the outsole 218 and the vamp. However, in other examples, the abrasion-resistant protective element 202 may be engaged with the outsole 218 at the top edge of the outsole 218, rather than positioned below the outsole 218. In this way, degradation of the footwear can be prevented while maintaining sufficient flexibility.

[0117] Go to Figure 4 , Figure 4 A top view of a second example footwear article 400 is shown. As can be seen from the top view of the second example footwear article 400, the second example footwear article is substantially similar to the first example footwear article. For example, as in the first example footwear article, the second example footwear article 400 includes a flexible abrasion-resistant forefoot guard 402 positioned at the metatarsophalangeal joint region 101 of the footwear article, the flexible abrasion-resistant forefoot guard 402 including, Figures 1 to 3 Features similar to ribs 402a and grooves 402b discussed in the text. Furthermore, Figure 4 The flexible abrasion-resistant forefoot cover 402 extends from the outsole located on the first side of the footwear article through the forefoot of the footwear article and extends to the outsole on the opposite side of the footwear article. However, significantly, the flexible forefoot cover 402 of the second example footwear article is partially positioned below the first instep 434 and the second instep 435 of the second example footwear article.

[0118] That is, instead of the flexible abrasion-resistant forefoot guard 402 of the second example footwear article being bent to accommodate the first shoe waist 434 and the second shoe waist 435, the second example footwear article has a flexible abrasion-resistant forefoot guard 402 arranged such that the first shoe waist 434 and the second shoe waist 435 are positioned on top of the flexible abrasion-resistant forefoot guard 402. Furthermore, the flexible abrasion-resistant forefoot guard 402 is integrated into the forefoot of the footwear article. Similar to the first example, the flexible abrasion-resistant forefoot guard 402 is smaller in size than the forefoot of the footwear article. Therefore, a gap 410 exists between the flexible abrasion-resistant forefoot guard 402 and the toe cap 404. In one or more examples, the flexible abrasion-resistant forefoot guard 402 may not be connected to the toe cap 404. The flexible abrasion-resistant forefoot guard 402 extends to the first shoe waist 434 and the second shoe waist 435 of the second example footwear article. Specifically, the flexible abrasion-resistant protective component 402 of the third example footwear article is positioned below a portion of the first upper 234 and a portion of the second instep 235.

[0119] In the second example footwear article, the heel cap may not be connected to the flexible forefoot protector 402 or the toe cap 404. In contrast, the heel cap of the first example footwear article is integrated with the flexible forefoot abrasion protector and the toe cap.

[0120] Furthermore, the corrugated tubing of the second example footwear article extends substantially laterally below the first and second waistband materials 234 and 235. In contrast, the flexible abrasion-resistant forefoot protection of both the first and second example footwear articles is shaped to bend around the first and second waistbands.

[0121] look Figure 5 , Figure 5A partial front view of a third example footwear article 500 is shown. Compared to both the first and second example footwear articles, the third example footwear article includes an abrasion protector 502 (also referred to as a flexible forefoot abrasion protector or forefoot protector) that is not attached to the toe cap 504 of the third example footwear article. Furthermore, the abrasion protector 502 does not stretch across the outsole on one side of the footwear article to the outsole on the opposite side. Instead, the abrasion protector 502 is not attached to the outsole. The abrasion protector 502 may be integrated into the upper of the third example footwear article, rather than being formed as a cover located on top of the upper. Similar to the previously discussed footwear article examples, the third example footwear article has an abrasion protector 502 positioned on the metatarsophalangeal joint region 101 of the footwear article. The abrasion protector 502 includes a corrugated tubular structure having ribs 502a and grooves 502b (as in the previously discussed abrasion protector 502). The abrasion protector 502 also includes an extension 506 extending from the metatarsophalangeal joint region 101 toward the toe cap 504. This inclusion of the extension 506 advantageously improves the distribution of force throughout the footwear and prevents deterioration. It should be noted that in at least one example, the shape of the abrasion protector 502 can vary. For example, the abrasion protector 502 can actually be narrower and formed in a generally M-shaped configuration.

[0122] Briefly Figure 6 , Figure 6 A partial side view of the third example footwear item 600 at the toe area is shown. Figure 6 As shown, the abrasion-resistant protective component 502 is clearly spaced from the outsole 218, midsole 602, and toe cap 504. It should be noted that the midsole 602 includes... Figure 7 The top feature 604 and the middle feature 606 are discussed further in the text.

[0123] Now go to Figure 7 , Figure 7 A rear view of a third example footwear article 700 is shown, illustrating the heel area. Similar to the footwear articles previously discussed, the third example footwear article includes a heel guard 208 having multiple structural ribs 208a. In at least one example, these structural ribs 208a advantageously create a grip for the user to remove the footwear article. For example, the user can use the opposing foot to push against the structural ribs 208a or use another surface to generate a downward force on the structural ribs 208a to facilitate removing the footwear article.

[0124] It should be noted that, unlike the previous examples, Figure 7 The heel protector 208 may not be attached to other parts of the cover. Instead, Figure 7The heel protector 208 is actually a separate piece that can be attached as a cover to the heel portion of the footwear article according to any one or any combination of the methods discussed herein. In other words, the heel protector 208 can, for example, be adhered to the outer surface of the footwear article at the heel portion.

[0125] In addition to the above, Figure 7 Footwear items also include midsoles such as 602, such as in Figure 6 As discussed herein, the midsole includes a top feature 614 and a middle feature 616 located in the toe area of ​​the footwear article. Furthermore, in addition to the top feature 614 and the middle feature 616, the midsole 602 also includes... Figure 7 The texturing feature 618 shown is located in the heel area of ​​the footwear article.

[0126] The top feature 614 can be positioned between the midsole feature 616 and the upper of the footwear article. The midsole feature 616 can be positioned between the top feature of the midsole and the textured feature 618 in the heel area. The textured feature 618 can be positioned between the midsole feature 616 and the outsole 218 of the footwear article. The textured feature 618 of the midsole includes a plurality of recesses 620 that are substantially circular in shape.

[0127] Go to Figure 8 , Figure 8A front view of a fourth example footwear article 800 is shown. It should be noted that the abrasion protector 802 of the fourth example footwear article extends further rearward toward the heel of the footwear article than the abrasion protectors in the previous examples. Furthermore, the abrasion protector 802 of the fourth example footwear article is positioned between the shoe waist plate and the outsole of the footwear article. The abrasion protector 802 extends from a first side of the outsole 218 located on the outer side of the footwear article, passes through the forefoot (including the metatarsophalangeal joint area 101), and extends to a second side of the outsole 218 located on the inner side of the footwear article (opposite to the first side). The abrasion protector 802 includes a parallel corrugated tube having parallel ridges 804 and valleys 808 forming multiple curves. Specifically, the ridges 804 and valleys 808 of the corrugated tubular feature each include a first curve 804a, which curves around the front edge 234a of the first shoe waist piece 234 towards the toe of the footwear. The ridges 804 and valleys 808 of the corrugated tubular feature also include a second curve 804b between the first shoe waist piece 234 and the second shoe waist piece 235, and between the toe of the footwear and the lacing structure of the footwear, which curves towards the tongue 232 of the footwear. The ridges 804 and valleys of the corrugated tubular feature also include a third curve 804c. Both the first curve 804a and the second curve 804c curve approximately at the points where the shoe waist pieces 234 and 235 reach their peaks during their extension towards the toe of the footwear. The second curve 804b is positioned between the tongue 232 and the toe cap 806 of the footwear. The curvature in the ridge 804 and valley 808 advantageously results in the corrugated fitting bending in a comfortable manner while still protecting footwear from deterioration.

[0128] In at least one example, the ridge 804 of the bellows fitting may correspond to the peak of the bellows profile (e.g., in...). Figures 10A-10F (The peaks discussed in the text). In at least one example, the ridge 804 of the bellows fitting may be positioned between two consecutive valleys 808 of the bellows fitting. The valleys 808 of the bellows fitting may correspond to valleys of the bellows-like profile (e.g., in...). Figures 10A-10F The valley discussed in the middle).

[0129] Now go to Figure 9 , Figure 9 A side view of the fifth example footwear item 900 is shown. (As in...) Figure 9As can be seen, the ridge 804 formed by the corrugated tubing of the abrasion protector 902 has a bend that is generally aligned with the lacing guide in the shoe waist piece. Therefore, the ridge 804 formed by the corrugated tubing bends from the tongue of the footwear to the waist piece, extending at an angle of approximately 25 to 50 degrees relative to the direction of extension of the midsole 924. Although the opposite sides are not shown, it should be noted that the abrasion protector 902 extends from the outer side of the footwear to the inner side, extending across the metatarsophalangeal joint region 101. Specifically, the abrasion protector 902 engages with the midsole 924 on either side of the footwear. In at least one example, the abrasion protector 902 may be partially positioned between the midsole 924 and the upper, such that the abrasion protector is partially located below the midsole 924.

[0130] exist Figure 9 In the example footwear article shown, the toe guard includes a first toe guard material 904, a second toe guard material 908, and a ridge 906 located between the first toe guard material 904 and the second toe guard material 908. In at least one example, the first toe guard material 904 may include a first material, wherein the first material is a flexible material such as leather, TPU, etc. The second toe guard material 908 may include a second material, wherein the second material is less flexible than the first material. In at least one example, the second material may be a rubber or plastic material. Furthermore, in at least one example, the second material may be a textured material, such that the first material is smoother than the second material. In addition to including the ridge 906, the second toe guard 908 may also include a gripping portion 910. Such a construction can help prevent deterioration of the toe area of ​​the footwear article while still maintaining flexibility.

[0131] In addition to the toe protection features Figure 9 The footwear article also includes a shoe waist panel 234, which may include a first material. In at least one example, the shoe waist panel 234 may also include one or more features formed by shoe seams 238. In at least one example, such features may be reinforcing features. Figure 9 In footwear, a padding feature 912 may be present at the ankle area in at least one example. The padding feature 912 may include one or more openings 914. In at least one example, such openings advantageously allow air to be expelled from the padding feature 912 upon compression. In addition to the padding feature 912, Figure 9The footwear articles in at least one example also include a heel pull tab 916, which can be used to pull the shoe up. Furthermore, areas of the upper may include a third material, such as in areas 924 and 928. It should be noted that in at least one example, areas 924 and 928 may be the base of the upper, and the waistband material 934, abrasion protection 902, and toe protection features may all be coverings on top of the base.

[0132] Figure 9 The footwear also includes a molded lateral heel panel 918, which includes a molded protective element 920. When the footwear is worn, the molded protective element 920 is positioned approximately at the user's ankle. The molded protective element 920 may also wrap around the heel of the footwear. In at least one example, the molded protective element 920 provides additional lateral stiffness.

[0133] As can be seen further, Figure 9 The footwear includes an outsole 218 with various textured features. These textured features include ribs 922 at the heel of the footwear. It should be noted that the textured features of the outsole 218 (such as ribs 922) can advantageously improve the grip of the footwear.

[0134] Now turn to Figures 11-35, which show various feasible corrugated tubular structures. It should be noted that... Figure 1-Figure 1 One or more of the corrugated tubular structures described in Figure 0 may be used in combination with any one or more of the corrugated tubular structures in Figures 11-35. Alternatively, in at least one example, one or more of the corrugated tubular structures described in Figures 11-35 may be used as Figure 1-Figure 1 Alternatives to the examples described in 0, or as... Figure 1-Figure 1 One or more of the corrugated tubular structures described in Figure 0 may be used without combination with any of the corrugated tubular structures discussed in Figures 11-35. It should be noted that combined corrugated tubular structures may include one or more of the profile, positioning, and curvature of combined corrugated tubular features. Furthermore, in at least one example, the representation of the corrugated tubular structure (such as in...) Figure 13 Figure 16, Figure 22 Figure 26 , Figure 29 (As shown in Figure 33) can be a covering attached to the top of the upper of a footwear item. Alternatively, a corrugated tubular construction (such as in...) Figure 13 Figure 16, Figure 22 Figure 26 , Figure 29 (As shown in Figure 33) may include the upper itself, and thus illustrates how the overlay and the upper have been integrated together.

[0135] Turning now to Figure 11, Figure 11 shows a side view of the sixth example footwear article 1100 between the vertical axis 1114 and the horizontal axis 1115. As can be seen in Figure 11, abrasion protection can be positioned at one or more of the following locations: the forefoot (including the metatarsophalangeal joint area 101), the outsole located below the forefoot, the heel, and the flex abrasion protection 1104 above the bridging area 1112 of the footwear article. It should be noted that in Figure 13 The second piece 1310 described herein is positioned directly above the bridging region 1112. In at least one example, these wear-resistant protective elements include those that can have, for example... Figure 10A , Figure 10B and Figure 10C The corrugated tubular profile shown in any one or more of the examples. Additionally or alternatively, in the sixth example footwear article, such as... Figures 10D to 10F The corrugated tube profile discussed in the text is also feasible.

[0136] Abrasion protection 1102 may be positioned at the forefoot, including the metatarsophalangeal joint region 101. Outsole abrasion protection 1108 may be positioned at the outsole of the footwear article located below the forefoot. Heel abrasion protection 1106 may be positioned at the heel region of the footwear article. Flex abrasion protection 1104 may be positioned adjacent to the bridging member 1112 of the footwear article. It should be noted that flex abrasion protection 1104 may not have a lining. Briefly referring to Figure 12, which shows a rear view of a sixth example footwear article 1200, the heel protection device 1106 includes a plurality of corrugated tubular features extending across the heel of the footwear article. In at least one example, further variations of the corrugated tubular features shown are possible. For example, while the corrugated tubular features shown for the heel abrasion protection 1106 are generally V-shaped, additional ribs that are arcuate and have a narrower profile may be included. In at least one example, this additional rib may be included in the top portion of the heel abrasion protection 1106. Furthermore, it should be noted that in at least one example, the heel protection 1106 may be sewn to the upper of the footwear article, such that the heel protection 1106 is integrated into the heel of the footwear article. For example, the top of the heel protection 1106 may be sewn to the top of the upper and to the top of a padding positioned beneath the upper. In at least one example, the top may be a flange such as a tapered flange. The portion of the heel protection 1106 comprising a corrugated tubular structure, between the top and bottom ends, may include a lining. Specifically, the lining may be positioned behind the corrugated tubular portion of the heel protection 1106.

[0137] Furthermore, at the bottom end of the heel protector 1106, a lining may be positioned between the heel protector 1106 and the lining. On top of both the heel protector 1106 and the lining, the lining may be an upper material forming the outer surface of the footwear article. In at least one example, the upper may be directly sewn onto the top of the bottom end of the heel protector 1106. In at least one example, the bottom end of the heel protector may be, for example, a tapered flange.

[0138] In at least one example, the heel protector 1106 can be formed as a single piece with the upper panel wing. For example, the heel protector 1106 and the upper panel wing can be molded as a single piece using any one or any combination of materials discussed herein for abrasion protection. The single-piece heel protector 1106 and the upper panel wing can be symmetrical about the longitudinal axis of the heel protector 1106. In such an example, the heel protector 1106 and the upper panel wing can be wound around the top portion of the heel to the rear edge of the upper panel of the footwear and generally wound around to the top of the footwear at the area where the bridging region 1112 and the ankle 1113 meet (see Figure 11). The upper panel of this integrated heel protector 1106 may not extend on the tongue and may be positioned between the opening / lacing guide of the footwear. Triangular cutouts may be included in the upper panel wing located in a lateral position on the footwear. Furthermore, the one-piece heel protector 1106 and the shoe waist flap allow the bottom of the heel of the footwear article to be substantially completely uncovered on the rear and sides, and the sides of the ankle area of ​​the upper to be uncovered. This one-piece heel protector 1106 and shoe waist flap may include a tapered twill fabric flange at the edge for attachment to the footwear article. A minimal lining, such as a foam lining, may be included below the one-piece heel protector 1106 and shoe waist flap. The remainder of the hoop of the ankle 1113 (see FIG. 11) may be filled with foam. For example, foam may not be included on the inner surface of the footwear article, and the one-piece heel protector 1106 and shoe waist flap are positioned on the inner surface. Conversely, only the lining, the one-piece heel protector 1106, and shoe waist flap may be included on the inner surface of the footwear article. In at least one example, the heel protector 1106 and the winglet of the shoe waist panel may be sewn to the ankle portion 1113 of the footwear article (see Figure 11). For example, seams may be included along both side edges of the heel protector 1106. In at least one example, the seams may be visible on both the outer and inner sides of the footwear article.

[0139] In addition to the corrugated tubular feature, the wear-resistant protective component 1102 may also include one or more deformable features 1110. These deformable features 1110 may be generally rhomboid in shape. For example, see Figure 13 , Figure 13An example corrugated tubular construction of a sixth example footwear article 1300 according to one or more embodiments of the present disclosure is shown. It should be noted that references to things such as… Figure 13 Figures 16 and 22 Figure 29 The corrugated tubular structure shown in Figure 33 refers to corrugated tubular components that can be integrated into footwear. In other words, Figure 13 Figures 16 and 22 Figure 29 The corrugated tubular construction in Figure 33 illustrates corrugated tubing that can be integrated into footwear articles using one or more of the following methods: adhesives, stitching, acoustic welding, and direct molding. Figure 13 As can be seen, deformation feature 1110 includes two adjacent sheets 1110a and 1110b that are joined along crease 1302. These adjacent sheets 1110a and 1110b can both be triangular and together form a rhomboid deformation feature.

[0140] Each of the two adjacent triangular sheets 1110a and 1110b is angled downwards from the top surface of the footwear to meet at crease 1302. The deformation feature 1110 allows bending at crease 1302, and when bending occurs at deformation feature 1110, its shape helps prevent unwanted deformation of other parts of the bellows. Including such a deformation feature 1110 advantageously improves the flexibility of the footwear. Specifically, deformation feature 1110 can be strategically positioned throughout the footwear to provide localized flexibility where needed. For example, deformation feature 1110 can be positioned end-to-end across the length of wing 1318 and across the length of wing 1320, with the associated crease 1320 aligned end-to-end. This positioning of deformation feature 1110 in the first wing 1318 introduces increased flexibility, particularly at the location where deformation feature 1110 is positioned. The second wing 1320 may also include a similar construction to the first wing 1318.

[0141] although Figure 13 The arrangement of deformation features 1110 shown is one possibility; however, it should be noted that other arrangements of deformation features 1110 are also possible without departing from the scope of this disclosure. For example, in at least one example, the bending guard 1104 may include more or fewer deformation features. For example, three end-to-end aligned deformation features 1110 may be present at the bending guard 1104, instead of just two. Similar modifications may be made to the arrangement of deformation features 1110 in one or more of the intermediate sheet 1304, the first wing 1318, and the second wing 1320. Additionally or alternatively, in at least one example, the deformation features 1110 may be located in different positions throughout the corrugated tubular structure 1300.

[0142] In at least one example, the shoe seam 1326 may extend onto the first piece 1308 and the second piece 1310 of the tongue 232, aligned with the crease 1302 of the deformation feature 1110 formed in the bending guard 1104. Furthermore, it should be noted that in at least one example, the bending guard 1104 may be sewn to the first piece 1308 and the second piece 1310. For example, a flange (such as a tapered flange) at a first end of the bending guard 1104 may be positioned between the outer layer of the first piece 1308 and the foam lining the back of the first piece 1308. Similarly, a flange at a second opposite end of the bending guard 1104 may be positioned between the outer layer of the second piece 1310 and the foam lining the back of the second piece 1310.

[0143] As for the abrasion-resistant protective element 1102, it can also be joined to the second piece 1310 via a shoe seam. In at least one example, the abrasion-resistant protective element can be sewn onto the top of the second piece 1310. Furthermore, in one or more examples, the end of the abrasion-resistant protective element 1102 sewn onto the top of the second piece 1310 may not be tapered, and the opposite ends of the abrasion-resistant protective element 1102 may include tapered flanges.

[0144] Observing the first wing 1318 and the second wing 1320, it should be noted that the outer edges of the corrugated tube 1322 at the first wing 1318 and the outer edges of the corrugated tube 1324 at the second wing 1320 can be shaped to match the top line of the midsole or outsole to which the corrugated tubular construction 1300 of the footwear article is attached. In particular, some footwear articles do not include a midsole. Therefore, in such examples, the outer edges 1322 and 1324 can be shaped to match the outsole of the footwear article. However, in cases where the footwear article includes a midsole, the outer edges 1322 and 1324 can be shaped to match the midsole. By matching the shapes of the outer edges 1322 and 1324 to match the outsole or midsole, it means that the curvature of the outer edges 1322 and 1324 is shaped to fit along the midsole or outsole in an aligned manner without gaps. This example of the corrugated tube outer edges matching the midsole of the footwear article can be seen at the abrasion protection 1102 in Figure 11. In this way, the corrugated tube in the corrugated tubular structure can extend from the outsole on the first side of the footwear to the outsole on the opposite side of the footwear.

[0145] In at least one example, it should be noted that one or more of the abrasion protection 1102, flex protection 1104, and heel protection 1106 may include tapered edges or flanges such as twill fabric flanges to make it easier to integrate with footwear items.

[0146] Turning to the tongue 232, the tongue 232 includes a first piece 1308, a flexural abrasion protector 1104, and a second piece 1310. The first piece 1308 and the second piece 1310 may comprise a first material different from the second material of the flexural abrasion protector. For example, the first piece 1308 and the second piece 1310 may comprise leather, while the flexural abrasion protector 1104 may comprise a plastic (such as TPU) or rubber material. A corrugated tube formed into the tongue 232 includes a slight bend along the central midline of the entire corrugated structure toward the top of the tongue 232. The tongue 232 may include two sets of aligned deformation features 1110, the deformation features 1110 being symmetrical about the central midline of the corrugated structure. It should be noted that the entire corrugated structure, including the ridge 1312, the valley 1314, and the deformation features 1110, is symmetrical about the central midline of the corrugated structure 1300. Furthermore, it should be noted that the ridges of the corrugated pipe fittings mentioned herein (such as ridge 1312) should be understood as corresponding to Figures 10A-10F The peaks shown in the figure can be followed as follows Figures 10A-10F Any one or any combination of the contours discussed herein. Similarly, valleys (such as valley 1314) mentioned herein should be understood as corresponding to Figures 10A-10F The valleys shown in the diagram can be followed as follows: Figures 10A-10F Any one or any combination of the outlines discussed in the text.

[0147] The intermediate sheet 1304 is positioned between the first wing 1318 and the second wing 1320, and below the tongue 232, with additional deformation features 1110 located within it. These deformation features (similar to deformation features 1110 of the first wing 1318 and the second wing 1320) are positioned end-to-end, and the associated creases 1302 are aligned end-to-end.

[0148] In one or more examples, the corrugated tubular structure may be formed as a single piece for the first wing 1318, the second wing 1320, the intermediate sheet 1304, and the tongue 232. Note that in at least one example, the first wing 1318 and the second wing 1320 may also be referred to herein as wings.

[0149] Optionally, in at least one example, the wings 1318, 1320 and the middle piece 1304 may be formed as a single forefoot piece, the flexural abrasion protection 1104 positioned on the tongue 232 may be formed as a separate tongue piece, and the heel protector 1106 may be formed as yet another separate piece. It should also be noted that the heel protector 1106 may have a shape variation. For example, as an alternative shape variation, the heel protector 1106 may be formed in a generally hourglass shape. Regarding the tongue 232, it should be noted that the portion of the tongue excluding the flexural protection 1104 may be padded. That is, one or both of the first piece 1308 and the second piece 1310 may be padded. In some examples, such padded at the first piece 1308 and / or the second piece 1310 may include leather overlays. The flex protection 1104 can be sewn to the first piece 1308 and the second piece 1310, such that the flex protection is integrated into the direction of the tongue 232, rather than being placed on top of the tongue 232. Furthermore, in at least one example, a material may be present connecting the wings 1318, 1320 and the tongue 232. Specifically, material may be included to attach the edges of the wings 1318, 1320 opposite to the toe edge 1316 of the corrugated structure 1300 to the outer edge of the tongue 232 near the wings 1318, 1320. Including such material helps maintain the proper positioning of the corrugated structure on footwear. In addition to the corrugated structure shown, it should be noted that between the tongue 232 and the middle piece 1304, in Figure 13 The throat of the corrugated tubular structure shown may include additional corrugated fittings in the form of ribs and grooves. Furthermore, in at least one example, Figure 13 The corrugated tubular structure shown may also include openings formed therein for attachment to footwear items.

[0150] Between the deformation feature 1110 of the middle sheet 1304 and the deformation features 1110 of the wings 1318 and 1320, it is noted that the ridges 1312 and valleys 1314 of the corrugated tube curve toward the toe edge 1316 of the corrugated structure 1300. In contrast, between the deformation feature 1110 on the first side of the middle sheet 1304 and the deformation feature on the second side of the middle sheet 1304, the ridges 1312 and valleys 1314 of the corrugated tube curve toward the tongue of the corrugated structure 1300. This curvature improves the movement of the corrugated tube and the user during footwear use. Furthermore, Figure 13 The curvature of the ridges 1312 and valleys 1314 of the corrugated fitting shown further enhances user comfort by helping to prevent the wear-resistant protective element from piercing the user's foot during use. In at least one example, Figure 13 The corrugated tubular structure in the middle is symmetrical about the central axis 2210.

[0151] Turning now to Figure 14, Figure 14 shows a side view of a seventh example footwear article 1400 according to one or more examples of the present disclosure. As can be seen in Figure 14, the footwear article includes an abrasion protector 1402 positionable at the forefoot, the forefoot including a metatarsophalangeal joint region 101. The footwear article may also include one or more of a flexural abrasion protector 1404 positioned on the tongue of the footwear article and a heel abrasion protector 1406 positioned at the heel region of the footwear article. Briefly referring to Figure 15, which shows a rear view of the seventh example footwear article 1500, the heel protector 1406 includes a plurality of corrugated tubular features in a grid structure, wherein the grid includes a plurality of quadrilaterals 1412 extending across the heel of the footwear article. The grid includes a curvature toward the outsole 218 of the footwear article. In at least one example, it should be noted that the heel protector 1406 may also include one or more rib structures that follow a curvature similar to that of the grid. It may also include an arcuate extension at the top of the heel protector 1406 that accommodates these additional rib structures. Furthermore, it should be noted that in at least one example, the shape of the heel protector 1406 may vary. For example, the heel protector 1406 may be generally triangular in shape and have an arcuate flange at each point of the triangle. In at least one example, one or more of the arcuate flanges may be tapered. It should be noted that in at least one example, the edges of the heel protector 1406 may be sewn to the footwear article. For example, the top of the heel protector 1406 may include a flange sewn to the top of the footwear article, including on the top of the vamp and foam padding of the footwear article. The bottom of the heel protector 1406 may include a flange (such as a tapered flange) sewn between the vamp and the lining of the footwear article. In at least one example, the lining may be positioned directly behind the mesh of the heel protector 1406. In at least one example, some or all of the edges of the heel guard 1406 may be tapered to form a tapered flange that adjoins the entire heel guard 1406.

[0152] As further shown in Figure 14, the footwear article may also include a pull tab 1408 extending from the top of the tongue of the footwear article. Briefly referring to Figure 17, which shows a outline view of the corrugated tubular construction of the seventh example footwear article, it can be seen that the pull tab 1408 is an extension of the flexural abrasion protection 1404. Specifically, as shown in Figure 17, the flexural abrasion protection 1404 is positioned on the top of and attached to the tongue 232. The pull tab 1408 extends from the flexural abrasion protection 1404 above the tongue 232 such that the pull tab 1408 is not directly attached to the tongue 232. Instead, the pull tab 1408 is indirectly attached to the tongue 232 through the flexural abrasion protection 1404. The pull tab 1408 also includes one or more ridges 1410, which make it easier to grip the pull tab 1408. The features of the pull tab 1408 advantageously enable the user to manipulate the tongue 232. In at least one example, the pull tab 1408 may comprise TPU and / or rubber material. Furthermore, in at least one example, the ridge 1410 of the pull tab 1408 may comprise a tapered edge.

[0153] Referring now to Figure 16, Figure 16 illustrates the corrugated tubular structure of a seventh example footwear article 1600. As can be seen in Figure 16, the corrugated tubular structure is a grid structure comprising a plurality of quadrilaterals 1412. In at least one example, the wings 1318 and 1320, the middle sheet 1304, and the tongue 232 of the corrugated tubular structure can be formed as a single piece, and the heel protector 1406 can be formed as a separate piece. The dimensions of the quadrilaterals 1412 of the grid can vary. Each quadrilateral 1412 of the grid can be molded to include a similar top surface shape as discussed in further detail below. Furthermore, the grid can be symmetrical about the central axis 2210 of the corrugated tubular structure 1600. In at least one example, the height of the quadrilaterals 1412 can vary within the grid. For example, the quadrilaterals 1412 positioned along the middle sheet 1304 can be shorter than the quadrilaterals 1412 positioned on the wings 1318 and 1320. In at least one example, the connection portion where wings 1318 and 1320 meet the intermediate sheet 1304 may have a height variation, and the quadrilateral 1412 of the intermediate sheet 1304 is shorter at the connection portion than the quadrilateral 1412 of wings 1318 and 1320. Similar to... Figure 13 In the example, the outer edges 1318 and 1320 of the grid formed by quadrilaterals 1412 can be curved to match the shape of the top line of the midsole. Alternatively, in an example where a midsole may not be present, the outer edges 1318 and 1320 of the grid formed by quadrilaterals 1412 can be curved to match the top line of the outsole. In this way, the outer edges 1318 and 1320 can be positioned adjacent to the midsole or outsole in an aligned manner without gaps.

[0154] In at least one example, the corrugated tubular mesh portion of the tongue 232 can be attached to the tongue of the footwear article by means of material wrapped from the back of the tongue to the top of the corrugated tubular mesh portion of the tongue 232. This material can be sewn onto the top of the tongue 232 portion at the edge of the corrugated tubular mesh. This material is not sewn onto the top of the quadrilateral 1412. In at least one example, foam can be positioned between the material and the corrugated tubular mesh for filling. This flange can be wrapped around the tongue of the footwear article.

[0155] The grid-like corrugated tubular construction shown in the figure advantageously improves bending at each location. For example, while other corrugated tubular constructions discussed herein may be suitable for bending across the front of the foot from the center outwards, the grid construction allows the user to bend at any location. It should also be noted that the quadrilaterals 1412 of the grid are separated by valleys 1602 (also referred to herein as voids). The inclusion of such valleys 1602 allows for bending in combination with the structure of each of the quadrilaterals 1412, to bend in both bent and extended positions. In at least one example, the quadrilaterals 1412 may correspond to... Figure 10F The quadrilateral at the location, and valley 1602 can correspond to Figure 10F The valley at the throat 1604 between the tongue 232 and the middle piece 1304 should be noted. Specifically, a valley 1604 (which may also be referred to herein as a gap) exists at the throat 1604 between the tongue 232 and the middle piece 1304 to ensure that the abrasion protection bends at the base of the throat.

[0156] Briefly referring to Figure 18, Figure 18 illustrates a schematic diagram of the corrugated tubular feature of a seventh example footwear article 1800 according to one or more embodiments of the present disclosure. As can be seen in Figure 18, the top surface 1418 of the quadrilateral is formed to follow the direction of manipulation. For example, the top surface 1418 of the quadrilateral 1412 is formed such that the top surface 1418 produces a concave structure when subjected to bending 1414. That is, when manipulated to bend, the top surface 1418 includes a notch as indicated by arrow 1414. Conversely, the top surface 1418 of the quadrilateral is formed such that the top surface is convex when subjected to extension 1416. That is, the top surface 1418 convexes outward as indicated by arrow 1416 in response to extension 1416. As can be seen in Figure 19, which illustrates a schematic representation of the corrugated tubular feature of the seventh example footwear article 1900, the top surface 1418 of the quadrilateral 1412 is concave (as in its original position). In other words, when not undergoing bending or stretching, the top surface 1418 of quadrilateral 1412 is concave.

[0157] Turning now to Figure 20, Figure 20 shows a side view of an eighth example footwear article 2000 according to one or more embodiments of the present disclosure. As can be seen in Figure 20, the footwear article includes an abrasion protector 2002 positionable at the forefoot, which includes a metatarsophalangeal joint region 101. The abrasion protector 2002 may include a similar mesh construction discussed in Figures 14-19. The footwear article may also include one or more of a curved abrasion protector 2004 positioned on the tongue of the footwear article and a heel abrasion protector 2006 positioned at the heel region of the footwear article. Briefly referring to Figure 21, which shows a rear view of the eighth example footwear article 2100, the heel protector 2006 includes a plurality of corrugated tubular features in the form of a curved slit structure, wherein the spline 2102 closest to the outsole 2104 is curved in a direction away from the outsole. As spline 2102 moves further away from the outsole, the curvature of spline 2102 gradually reverses and eventually bends in the direction toward the outsole 2104. As can be seen in Figure 20, spline 2102 helps provide structural characteristics while still allowing the heel guard 2006 to bend (as shown in 2008) during bending. The flexural abrasion guard 2004 may include the spline construction discussed in detail in Figure 22.

[0158] Turning to Figure 22, Figure 22 illustrates a corrugated tubular construction of a ninth example footwear article 2200 according to one or more embodiments of the present disclosure. As can be seen in Figure 22, the corrugated tubular construction includes a plurality of spline lines 2102 having various sizes and curvatures. Additionally, a plurality of slits 2202, 2204, 2206, and 2208 form the corrugated tubular construction, the slits being substantially perpendicular to at least a portion of the plurality of spline lines 2102. It should be noted that the slits and spline lines are symmetrical about the central axis 2210 of the corrugated tubular construction. Slits 2202, 2204, 2206, and 2208 all extend along the length of the tongue 232 and curve inward toward the central axis 2210. Furthermore, it should be noted that the length and curvature of the spline lines 2102, as well as the spacing between the plurality of spline lines, are varied to accommodate specific movements of the footwear article. That is, the spacing, length, and specific curvature of the spline lines 2102 in Figure 22 achieve specific movement advantages. For example, Figure 23 shows a profile of the corrugated tubular construction of the ninth example footwear article 2300. As shown in Figure 23, the spacing between the spline lines 2102 located in region 2302 near the toe side edge 1316 of the corrugated tubular construction in Figure 22 is smaller than the spacing between the spline lines 2102 located in region 2304 on the tongue 232. In particular, more flexibility is required in region 2302 than in region 2304. Furthermore, the degree of curvature at the middle piece 1304 in Figure 22 is different from (higher than) the curvature on the tongue 232 to achieve increased flexibility.

[0159] Turning now to Figure 24, which shows a side view of the tenth example footwear article 2400. As shown in Figure 24, the footwear article includes an abrasion protector 2402 that can be positioned on the forefoot (including the metatarsophalangeal joint region 101). Additionally, the footwear article includes a first flexure abrasion protector 2404 and a second flexure abrasion protector 2406, both positioned on the tongue 232 of the footwear article. Furthermore, the footwear article in Figure 24 may include a first heel protector 2408, a second heel protector 2410, and a third heel protector 2412. Briefly referring to Figure 25, which shows a rear view of the tenth example footwear article 2500.

[0160] As shown in Figure 25, the first heel protector 2408, the second heel protector 2410, and the third heel protector 2412 all include different corrugated tubular profiles. However, it is conceivable that only some of the corrugated tubular profiles and / or heel protectors may be used in one or more examples. In at least one example, the first heel protector 2408 may include a corrugated tube that is relatively narrow and very close to another corrugated tube in the footwear article. That is, the peaks 2502 and valleys 2504 of the corrugated tube at the first heel protector 2408 may be relatively narrow compared to the corrugated tubes of the rest of the footwear article. Furthermore, the ridges (peaks 2502) and valleys 2504 of the first heel protector 2408 extend substantially straight and parallel to the bottom of the outsole 2506. The length of each corrugated feature (wherein each corrugated feature includes two valleys and a peak structure located between them) is narrowest at the top of the ankle and widest near the outsole 2506. Compared to the flexibility of the second heel protector 2410 and the third heel protector 2412, the corrugated tubular structure used for the first heel protector 2408 can be more flexible. This increased flexibility at the top of the ankle of the first heel protector 2408 makes the footwear easier to put on and take off.

[0161] The second heel protector 2410 includes a corrugated tubular structure in which the peaks 2508 may have different shapes from each other. For example, the uppermost peak 2508 immediately adjacent to the first heel protector 2408 is wider than the remaining peaks 2508 of the second heel protector 2410. Furthermore, as shown in FIG. 24, the lateral profile of the uppermost peak (labeled 2508 in FIG. 25) of the second heel protector 2410 differs in shape and curvature from the remaining peaks 2508 of the second abrasion protector 2410. In particular, the uppermost peak may be shaped to allow it to easily compress downward toward the remaining peaks. This shaping can be an economical option for shoe seams and layers to produce both structural integrity and flexibility.

[0162] Regarding the third heel protection device 2412, the third heel protection device 2412 includes a corrugated tube with peaks 2512, the peaks 2512 being in a raised strip structure between valleys 2514.

[0163] It should be noted, for example, in Figure 24- Figure 26 Any corrugated pipe fitting described herein may have similar characteristics to those in this disclosure. Figure 10D The raised strip corrugated tubular profile discussed in the text. Within the raised strip profile, a capsule shape can be incorporated to provide flexibility and stability.

[0164] For example, referring back to Figure 24, any one or any combination of the abrasion-resistant protective component 2402, the first flexural protective component 2404, the second flexural protective component 2406, and the heel protective components 2408, 2410, and 2412 may include, for example, Figure 10D The raised strip structure is shown in the figure. Footwear articles may also include one or more of a flexural abrasion protection 2004 positioned on the tongue of the footwear article and a heel abrasion protection 2006 positioned in the heel area of ​​the footwear article.

[0165] Continuing with Figure 24, as can be seen, the wing 1318 can be a region including recessed grooves, the wing 1318 including at least one peripheral groove 2414a and one or more lateral grooves 2414b. Additional grooves 2414 may also be formed in the ankle flexion area of ​​the upper. The wing 1318 may also be constructed without any raised strips to aid flexion and thus only include recessed grooves. Specifically, as shown in the tenth example footwear article 2600, a corrugated tubular construction... Figure 26 As shown, slots 2414a and 2414b are positioned in wing 1318 without any rods.

[0166] like Figure 26 As can be further seen, the corrugated tubular construction may include a first piece 2602 and a second piece 2604 of the tongue 232, wherein the first piece 2602 and the second piece 2604 do not include any corrugated tubular structure. Furthermore, it can be seen that the first bending protection 2404 includes a corrugated tubular construction having peaks 2606 and valleys 2608.

[0167] Turning now to Figure 27, which shows a side view of the eleventh example footwear article 2700. As can be seen in Figure 27, the footwear article includes an abrasion-resistant guard 2702 that can be positioned at the forequarter, which includes a metatarsophalangeal joint area 101 (see Figure 27). Figure 29Additionally, a flexural abrasion protector 2704 is positioned on the tongue of the footwear article, and a heel protector 2706 is positioned at the heel of the footwear article. Briefly referring to Figure 28, which shows a rear view of the eleventh example footwear article 2800, in at least one example, the heel protector 2706 may be a one-piece heel protector. Referring back to Figure 27, it should be noted that an outsole abrasion protector 2708 may also be included.

[0168] In at least one example, it can be similar to Figure 10E The corrugated profile in Figure 27, specifically the abrasion-resistant protective elements (2702, 2704, 2706, 2708), includes a peak 2710 and a valley 2712. It should be noted that each abrasion-resistant protective element in Figure 27 comprises corrugated elements that extend entirely at substantially the same angle. For example, as can be seen in Figure 28, the corrugated elements of the heel protector 2706 all extend at the same angle and are part of a single element. Furthermore, as shown in the eleventh example of the corrugated construction of footwear article 2900... Figure 29 As can be seen, the bellows extends at the same angle and is part of a single component. The wear-resistant protective element can be molded such that the bellows is convex. In at least one example, Figure 27- Figure 29 The corrugated tubular structure at the location can resemble a flexible tube. Furthermore, although footwear articles are shown as having a portion of the forefoot that does not include the corrugated tubular structure, it should be noted that in at least one example, the entire forefoot can be constructed from the portion shown in Figure 27- Figure 29 The structure shown is made of a corrugated tubular structure.

[0169] Now go to Figure 30 , Figure 30 A side view of the twelfth example footwear item 3000 is shown. (As in...) Figure 30 As can be seen, footwear items include flexural abrasion protection 3004, heel abrasion protection 3006, and abrasion protection 3002 that can be positioned on the forefoot (including the metatarsophalangeal joint area). Figure 30 In this design, the corrugated tube at the heel can be in the form of fins, and the thickness and depth of the fins are adjusted to increase or decrease the flexibility of the footwear. For example, looking at the first region 3008 of the heel protector 3006, fins 3014 (also referred to herein as strips) extend outward to create a pull tab. Therefore, the first region 3008 can also be referred to as the pull zone.

[0170] Now looking at the second region 3010 of the heel protector 3006, the fins 3014 are arranged inward to reduce material thickness and increase flexibility. Therefore, the second region 3008 can also be referred to as the bending region in this document.

[0171] The fins 3014 of the third region 3012 of the heel protector 3006 extend outward and are thicker than the other fins of the heel protector 3006. The closer the fins 3014 are to the outsole 3016, the greater their thickness becomes within the third region 3012 itself. This increased thickness advantageously adds structural integrity to the footwear. Therefore, in at least one example, the third region 3012 can be referred to as the structural region.

[0172] In at least one example, the wear protection device 3002 includes, as shown below: Figure 8 and Figure 9 The corrugated tubular structure is shown in the figure. However, in at least one example, the combination of the corrugated tubular structures discussed herein (including fins 3014) can be incorporated into the wear-resistant protective element 3002.

[0173] Turning now to Figure 31, Figure 31 shows a side view of the thirteenth example footwear article 3100. As can be seen in Figure 31, the footwear article includes an abrasion protector 3102 that can be positioned at the forefoot, which includes the metatarsophalangeal joint area (labeled 101 in Figure 33). A heel protector 3104 may also be included. The abrasion protector 3102 and the heel protector 3104 may include a corrugated tubular construction in the form of a plurality of finger-like projections 3106 to satisfy structural support while maintaining flexibility. For example, as shown in Figure 32, the plurality of finger-like projections 3106 are arranged in a configuration that wraps around the heel of the foot to increase structural support while maintaining flexibility.

[0174] Each finger protrusion 3106 may have a different height (including a height of approximately 0.0 mm). When the height is approximately 0.0 mm, the finger protrusion 3106 is capable of bending. Therefore, these locations with a height of approximately 0.0 mm are referred to as the bending points of the finger protrusion 3106 (see 3108 in Figures 34-35).

[0175] Briefly referring to Figures 34 and 35, Figure 34 shows a schematic representation of the morphology of the corrugated tubular structure of the thirteenth example footwear article 3400, and Figure 35 shows a contour view of the corrugated tubular structure of the thirteenth example footwear article 3500. It can be seen that each finger-like protrusion 3106 may include one or more bending points 3108. Additionally, the finger-like protrusion 3106 may include structural points 3402, which are peaks of the finger-like protrusion 3106. In at least one example, the height of the peak of the finger-like protrusion 3106 may be approximately 3.0 mm. However, other peak heights are also possible. For example, peak heights of approximately 5.0 mm to 8.0 mm are also possible.

[0176] As shown in Figure 34, the width of the finger protrusion 3106 increases with the increase of the height of the finger protrusion 3106 (also referred to herein as the thickness) (the height is shown in Figure 35). In this way, maximum structural stability is provided at structural point 3402, while maximum flexibility is provided at bending point 3108.

[0177] In at least one example, the bending points 3108 may be aligned to form a curved region 3110 of the footwear article. For example, as shown in FIG31, a first curved region 3110a and a second curved region 3110b are formed along the arrow by the alignment of a plurality of bending points 3108. Similarly, FIG33 shows a corrugated tubular construction for a thirteenth example footwear article 3300, wherein the curved region 3110 is shown along the arrow. It should also be noted that as the height of the finger protrusions 3106 increases with the width of the finger protrusions 3106, there are additional structural regions formed by the alignment of structural points 3402.

[0178] Therefore, a footwear article including an abrasion-resistant structure is provided herein, which prevents upper degradation while still maintaining the flexibility of the shoe. Specifically, the footwear article may include a flexible abrasion-resistant forefoot guard. In this way, the technical effects of reducing footwear degradation are achieved by maintaining the user's comfort and mobility are achieved. The footwear article according to this disclosure may include an upper and an abrasion-resistant guard comprising a corrugated tube positioned at the metatarsophalangeal joint region of the footwear article, wherein the material of the abrasion-resistant guard is different from the material of the upper of the footwear article. In a first example of the footwear article, the corrugated tube extends above the forefoot of the footwear article. In a second example of the footwear article, optionally including the first example, the corrugated tube extends from the outsole at a first side of the footwear article across the metatarsophalangeal joint region to the outsole at a second side of the footwear article. In a third example of the footwear article, optionally including one or both of the first and second examples, the corrugated tube bends rearward toward the heel of the footwear article. In a fourth example, which optionally includes one or more of the first to third examples, the upper is exposed between the toe cap and the abrasion protector. In a fifth example, which optionally includes one or more of the first to fourth examples, the abrasion protector is a one-piece molded structure. In a sixth example, which optionally includes one or more of the first to fifth examples, a heel protector is positioned at the heel of the footwear article, and the heel protector includes ribs formed therein. In a seventh example, which optionally includes one or more of the first to sixth examples, the toe cap, abrasion protector, and heel protector are an integral structure. In an eighth example, which optionally includes the first to seventh examples, a corrugated fitting overlaps with the waistband material of the footwear article.

[0179] A second footwear article, which may include one or more features of the aforementioned footwear article, includes an upper and an abrasion-resistant protective element constructed with corrugated tubing, wherein the corrugated tubing extends along the edge of the lacing structure of the footwear article and is located between the lacing structure and the toe cap. In a first example of the second footwear article, the corrugated tubing includes one or more lateral grooves. In a second example of the second footwear article, which optionally includes the first example, one or more lateral grooves curve toward the tongue of the footwear article in the area between the toe cap and the tongue. In a third example of the second footwear article, which optionally includes one or both of the first and second examples, the abrasion-resistant protective element extends onto the tongue of the footwear article. In a fourth example of the second footwear article, which optionally includes one or more of the first to third examples, the corrugated tubing forms a ridge that curves around the waist piece of the footwear article. In a fifth example of the second footwear article, which optionally includes the first to fourth examples, the abrasion-resistant protective element is integrated with the upper.

[0180] A third footwear article according to this disclosure, which may include any one or more features described above, includes an upper and an abrasion protector including a corrugated tube, wherein the corrugated tube is positioned adjacent to the tongue of the footwear article. In a first example of the third footwear article, the corrugated tube extends onto the tongue of the footwear article. In a second example of the third footwear article, which optionally includes the first example, the corrugated tube is positioned between the lacing structure of the footwear article and the toe of the footwear article. In a third example of the third footwear article, which optionally includes one or both of the first and second examples, the third footwear article further includes a heel protector including a plurality of ribs. In a fourth example of the third footwear article, which optionally includes one or more of the first to third examples, the abrasion protector is spaced apart from the outsole of the footwear article, wherein the upper forms part of the outer surface of the footwear article between the abrasion protector and the outsole of the footwear article.

[0181] In a fourth footwear article that optionally includes one or more of the aforementioned footwear features, the upper and abrasion protection structure include a toe cap positioned at the toe of the footwear article and a flexible fore-upper cover with corrugated tubes positioned at the fore-upper of the footwear article, wherein the material of the abrasion protection structure is different from the material of the upper of the footwear article. Including a flexible fore-upper cover with corrugated tubes positioned at the fore-upper of the footwear article can advantageously reduce upper degradation of the footwear article while still allowing sufficient mobility for the user. Furthermore, compared to integrating the flexible fore-upper abrasion protection element into the upper, the fact that the flexible fore-upper abrasion protection element is a cover in the first example footwear article, rather than being integrated into the upper, can advantageously result in improved user comfort. In the first example of the fourth footwear article, the corrugated tubes may include pleats, which in one or more examples include ribs and grooves. In a second example of the fourth footwear article that optionally includes the first example, the flexible fore-upper cover is smaller in size than the fore-upper of the footwear article. This method avoids adding excessive extra weight to footwear.

[0182] In a third example, which optionally includes one or more of the first and second examples, the abrasion protection construction further includes a gap positioned between the toe cap and the forefoot cover. In a fourth example, which optionally includes one or more of the first to third examples, the abrasion protection construction is a molded structure. In a fifth example, which optionally includes any one or more of the first to fourth examples, the abrasion protection construction further includes a heel protector positioned at the heel of the footwear article.

[0183] In a sixth example, which optionally includes any one or more of the first to fifth examples, the toe cap, the flexible fore-upper cover with corrugated tubing, and the heel protector can be an integrated structure. This integration of the toe cap, flexible fore-upper cover, and heel protector can cause the forces applied to the footwear (e.g., bending at the fore-upper part of the footwear) to be dispersed, preventing degradation of the footwear. Furthermore, this integration of the toe cap, flexible fore-upper cover, and heel protector can prevent degradation of these components themselves.

[0184] In a seventh example, which optionally includes any one or more of the first to sixth examples, the toe cap, flexible forefoot cover, and heel protector are connected to each other by a portion of the abrasion protection positioned around the periphery of the footwear article, the periphery of which is located between the forefoot and the outsole. The portion of the abrasion protection structure positioned around the periphery of the footwear article (also referred to herein as the periphery of the abrasion protection structure (e.g., periphery 222)) can advantageously enhance the bonding between the upper and the outsole of the footwear article.

[0185] In an eighth example, which optionally includes one or more of the first to seventh examples of the fourth footwear article, the fourth footwear article further includes an upper, a fore-upper abrasion protector with corrugated tubing at the fore-upper part of the footwear article, a toe cap positioned at the toe of the footwear article, and a gap between the fore-upper abrasion protector and the toe cap, the toe cap being integral with the fore-upper abrasion protector, wherein the materials of the fore-upper abrasion protector and the toe cap are different from the materials of the upper. In a ninth example, which optionally includes one or more of the first to eighth examples of the fourth footwear article, the corrugated tubing of the fore-upper abrasion protector includes one or more lateral grooves. In a tenth example, which optionally includes one or more of the first to ninth examples of the fourth footwear article, a heel cap is also included, wherein the flexible fore-upper abrasion protector, the toe cap, and the heel cap form a single integral piece. In an eleventh example, which optionally includes one or more of the first to tenth examples of the fourth footwear article, the upper can be positioned within the gap of the abrasion protection structure, the upper forming the outer surface of the footwear article at the gap. In the twelfth example, which optionally includes one or more of the first to eleventh examples, a corrugated abrasion-resistant fore-end guard constructed of corrugated tubing may be formed as a cover on top of the upper.

[0186] In a thirteenth example, which optionally includes one or more of the first to twelfth examples, the abrasion protection structure may further include an extension extending from the vamp of the footwear article to the tongue of the footwear article, the extension being configured with a corrugated tube. As described above, such an extension can advantageously further help prevent deterioration of the upper. In at least one example, the extension may be connected to and formed as a single piece with a flexible vamp abrasion protector. In a fourteenth example, which optionally includes one or more of the first to thirteenth examples, the abrasion protection extension positioned on the tongue of the footwear article may be vertically overlapped with the upper of the footwear article without being affected by the vamp or upper. In a fifteenth example, which optionally includes one or more of the first to fourteenth examples, the vamp abrasion protector configured with a corrugated tube may be integrated with the upper.

[0187] In one or more of the sixteenth examples, optionally including the first to fifteenth examples, the footwear article includes a flexible abrasion-resistant forefoot guard with a corrugated tube, a toe cap integrated into the flexible abrasion-resistant forefoot guard, and a gap defined by the flexible abrasion-resistant forefoot guard and the toe cap. In one or more of the seventeenth examples, optionally including the first to sixteenth examples, the footwear article includes an upper, wherein the forefoot portion of the upper is positioned within the gap. In one or more of the eighteenth examples, optionally including the first to seventeenth examples, the footwear article further includes a tongue, the flexible abrasion-resistant forefoot guard being integral with an extension, and the extension extending from the flexible abrasion-resistant forefoot guard to a lower portion of the tongue. Including the extension extending from the flexible abrasion-resistant forefoot guard to the lower portion of the tongue advantageously prevents the tongue from wrinkling during lacing. This wrinkling prevention improves user comfort and also prevents downstream degradation that can result from wrinkling. The extension can further help distribute forces to help prevent deterioration of the upper (especially at the forefoot).

[0188] In a nineteenth example, which optionally includes one or more of the first to eighteenth examples of the fourth footwear article, both the flexible fore-upper abrasion protection and the extension can be formed with corrugated tubing, thus including one or more ribs and one or more grooves formed therein. In a twentieth example, which optionally includes one or more of the first to nineteenth examples of the footwear article, one or more ribs of the flexible fore-upper protection are positioned more closely together than one or more ribs of the extension. This varying spacing of the ribs and grooves of the corrugated tubing, as in the twentieth example, advantageously ensures that the footwear article bends and moves in a manner that accommodates the user's movement, while still providing substantial structural integrity.

[0189] Therefore, footwear including flexible abrasion-resistant forefoot components as discussed above achieves the following technical effects: preventing degradation of the footwear in the forefoot area while still allowing for flexibility at the forefoot. Furthermore, it increases the lifespan of the footwear while maintaining user comfort and mobility.

[0190] It will be understood that the constructions and / or methods described herein are exemplary in nature, and because many variations are possible, these specific embodiments or examples should not be considered in a limiting sense. The subject matter of this disclosure includes all novel and non-obvious combinations and sub-combinations of the various features, functions, actions, and / or characteristics disclosed herein, as well as any and all equivalents thereof.
