[0003] In view of this, this application provides a sole and a shoe using the sole, which is beneficial to extend the service life of the shoe while improving the overall comfort of the shoe.

[0004] A first aspect of this application provides a shoe sole, including a sole body and a support piece fixed to the sole body. The sole body includes a heel portion, a forefoot portion, and an arch portion connecting the forefoot portion and the heel portion. The support piece has a higher hardness than the sole body, and includes a main body portion and an extension portion extending from the main body portion. The thickness of the main body portion is greater than the thickness of the extension portion, and one side of the main body portion is flush with one side of the extension portion. The sole body includes an upper surface and a lower surface facing away from each other, and a through hole penetrating the upper surface and the lower surface. The through hole is located in the arch portion to receive the main body portion, and the side of the main body portion flush with the extension portion faces away from the lower surface. The upper surface is recessed inward from the lower surface at least in the arch portion to form a recess, the recess communicating with the through hole and receiving the extension portion.

[0005] Based on the first aspect above, in some embodiments, the support sheet is a carbon plate, a nylon plate, or a thermoplastic polyurethane sheet.

[0006] Based on the first aspect above, in some embodiments, the recess extends to the forefoot portion, and the extension of the support piece extends to the forefoot portion.

[0007] Based on the first aspect described above, in some embodiments, the side of the main body portion flush with the extension portion is recessed inward toward the lower surface to form a depression, and the depression forms an opening on the side of the main body portion flush with the extension portion. The inner wall of the depression is an arc-shaped surface, and in the cross-section in the direction of the opening, the area of ​​the depression gradually decreases from the opening toward the direction away from the opening.

[0008] Based on the first aspect mentioned above, in some embodiments, in the thickness direction of the sole, the height of the main body portion is 5mm to 15mm, and one end of the main body portion away from the upper surface is located inside the through hole.

[0009] Based on the first aspect above, in some embodiments, the thickness of the extension gradually decreases from the end connected to the main body to the end away from the main body, and the depth of the recess gradually decreases from the end communicating with the through hole to the end away from the through hole.

[0010] Based on the first aspect above, in some embodiments, the side of the support piece opposite to the lower surface of the sole body is flush with the upper surface of the sole body.

[0011] Based on the first aspect described above, in some embodiments, the extension includes a first portion, a second portion, a third portion, and a fourth portion extending from the main body portion, respectively. The first portion and the second portion extend at an angle toward the forefoot portion, and the third portion and the fourth portion extend at an angle toward the rearfoot portion.

[0012] Based on the first aspect above, in some embodiments, the extension includes a forefoot region located in the forefoot portion, wherein the end of the forefoot region away from the arch portion forms two or three spaced grooves toward the arch portion.

[0025] The technical solutions of the embodiments of this application will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0027] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0028] Please see Figure 1 One embodiment of this application provides a shoe 100, including a sole 10 and an upper 20. The upper 20 is combined with the sole 10 to jointly define a receiving cavity (not shown) for receiving a user's foot. The upper 20 and sole 10 can be joined together in any desired manner, for example, by adhesives or bonding agents, stitching, or other mechanical connections. The upper 20 can be made of any desired material or constructed without departing from the present technology. For example, at least a portion of the upper 20 may include woven textile components, knitted textile components, natural leather components, synthetic leather components, polymer components, etc.

[0029] Please see Figure 1 and Figure 2 The sole 10 includes a sole body 11 and a support piece 13 fixed to the sole body 11. In this embodiment, the sole body 11 and the support piece 13 can be fixed by adhesive bonding. In some embodiments, the sole body 11 and the support piece 13 can also be fixed by snap-fitting, or by other means, such as but not limited to, connecting the two with shoe spikes.

[0030] The sole body 11 is divided into a heel portion 111, a forefoot portion 113, and an arch portion 115 connecting the heel portion 111 and the forefoot portion 113.

[0031] The sole body 11 includes an upper surface 11a, a lower surface 11b opposite to the upper surface 11a, and a through hole 11c penetrating the upper surface 11a and the lower surface 11b. Further, the through hole 11c is located in the arch portion 115 and penetrates the arch portion 115 in the thickness direction Z. In this embodiment, the sole body 11 may be composed of a midsole and an outsole stacked together. It is understood that in this case, the upper surface 11a is the surface of the midsole opposite to the outsole, the lower surface 11b is the surface of the outsole opposite to the midsole, and the through hole 11c penetrates the midsole and the outsole. The midsole and the outsole may be detachable or integrally molded.

[0032] Please refer to the following: Figures 3 to 6 The upper surface 11a is further recessed into the lower surface 11b at least in the arch portion to form a recess 11d, and the recess 11d communicates with the through hole 11c.

[0033] The support piece 13 has a higher hardness than the sole body 11. When the support piece 13 is fixed to the sole body 11, it can improve the support strength of the corresponding area.

[0034] Specifically, the support piece 13 includes a main body 131 and an extension 133 extending from the main body 131. The thickness of the main body 131 is greater than the thickness of the extension 133, and one side of the main body 131 is flush with one side of the extension 133.

[0035] The main body 131 is housed in the through hole 11c, and the extension 133 is housed in the recess 11d. Furthermore, the side of the main body 131 flush with the extension 133 faces away from the lower surface 11b, i.e., the side of the main body 131 flush with the extension 133 faces upwards. It can be understood that the extension 133 can be designed to conform to the shape of the recess 11d.

[0036] In the aforementioned shoe 100, because the sole 10 has a support plate 13 with high hardness and the support plate 13 is provided at least corresponding to the arch portion 115, the support strength of the sole 10 at the arch portion 115 can be improved, thereby enhancing the stability of the sole 10 and the entire shoe 100, and helping to extend the service life of the sole 10 and the shoe 100. Furthermore, the support plate 13 includes a thicker main body 131 and a thinner extension 133, and the main body 131 corresponds to the arch portion 115, further improving the support strength of the sole 10 at the arch portion 115 and providing better torsional resistance. In addition, the sole body 11 has the through hole 11c corresponding to the main body 131, which effectively reduces the weight of the sole 10 while improving the overall design of the shoe 100, thus enhancing the overall comfort of the shoe 100. Furthermore, the through hole 10c, in conjunction with the harder main body 131, helps to reduce wear caused by the interaction between the main body 131 and the sole body 11, and helps to extend the service life of the sole 10 and the entire shoe 100.

[0037] In some embodiments, the support plate 13 may be, but is not limited to, a carbon fiber plate, a nylon plate, or a thermoplastic polyurethane sheet. It is understood that the hardness of the carbon fiber plate, the nylon plate, or the thermoplastic polyurethane sheet needs to be higher than the hardness of the sole body 11. In some embodiments, the carbon fiber plate may include a first carbon fiber layer, a foam layer, and a second carbon fiber layer stacked sequentially, thereby improving both support strength and stability while enhancing foot feel and comfort. In other embodiments, the carbon fiber plate is not limited to the above structure; for example, it may simply be a carbon fiber layer.

[0038] In the thickness direction Z of the sole 10, the height of the main body 131 can be from 5mm to 15mm. One end of the main body 131 facing away from the upper surface 11a is located in the through hole 11c, meaning the main body 131 does not protrude from the sole body 11 through the through hole 11c. The main body 131 within the aforementioned height range helps to ensure the support strength and torsional resistance of the arch support 115.

[0039] In some embodiments, the side of the main body 131 flush with the extension 133 may be recessed inward toward the lower surface 11b to form a recess 135, and the recess 135 forms an opening 135a on the side of the main body 131 flush with the extension 133. The recess 135 enhances the support strength and stability of the sole 10 in the main body 131 while reducing the weight of the main body 131, thereby reducing the overall weight of the shoe 100 and improving the comfort of the shoe.

[0040] The opening 135a can be rhomboid, and the recess 135 is also rhomboid in the cross-section along the direction of the opening 135a. Furthermore, each included angle of each rhomboid is rounded. This rounded corner design helps reduce stress concentration.

[0041] The inner wall 135b of the recess 135 can also be an arc-shaped surface, and in the cross-section along the direction of the opening 135a, the area of ​​the recess 135 gradually decreases from the opening 135a toward the direction away from the opening 135a. This design facilitates smoother and more natural rolling of the shoe 100.

[0042] The side of the support piece 13 facing away from the lower surface 11b can be flush with the upper surface 11a, which helps to maintain the overall shape of the upper surface 11b of the sole 10 and ensures comfort.

[0043] In some embodiments, the thickness of each region of the extension 133 is uniform. In other embodiments, the thickness of the extension 133 may gradually decrease from the end connected to the main body 131 toward the end away from the main body 131, that is, the thickness of the extension 133 becomes thinner and thinner from the main body 131 outwards. Correspondingly, the depth of the recess 11d gradually decreases from the end communicating with the through hole 11c toward the end away from the through hole 11c. The above design is beneficial for improving support strength and stability through the extension 133 while ensuring the rebound effect and deformation flexibility of the sole 10, thereby improving comfort.

[0044] The thickness of the thinnest part of the extension 133 can be greater than or equal to 1.3 mm, which helps to ensure the support strength of the support piece 13.

[0045] like Figures 2 to 3 As shown, the support piece 13 may be approximately X-shaped. Specifically, the extension 133 may include a first portion 133a, a second portion 133b, a third portion 133c, and a fourth portion 133d extending from the main body portion 131, respectively. The first portion 133a and the second portion 133b are arranged at an angle and extend toward the forefoot portion 113, respectively. The third portion 133c and the fourth portion 133d are arranged at an angle and extend toward the heel portion 111, so that the support piece 13 is approximately X-shaped when the sole 10 is viewed from above.

[0046] Please see Figure 7 The recess 11d can also extend to the forefoot portion 113. Correspondingly, the extension 133 of the support piece 13 extends to the forefoot portion 113. When the user runs, the above structure can provide better rebound and propulsion rolling when the shoe deforms, thereby improving the comfort of the shoe.

[0047] like Figure 7 The extension 133 may include a forefoot area 133e located in the forefoot portion 113. Further, the end of the forefoot area 133e away from the arch portion 115 may form two or three spaced grooves 133f toward the arch portion 115, thereby forming multiple branches at one end of the forefoot area 133e. This increases the flexibility of the forefoot area 133e of the support plate 13 in terms of deformation while improving the support strength and stability through the support plate 13, thereby improving the overall comfort of the shoe 100.

[0048] Furthermore, a limiting portion 133g may be provided on the side of the forefoot area 133e facing the lower surface 11b. Correspondingly, the forefoot portion 113 also includes a limiting groove 11e penetrating the upper surface 11a and the lower surface 11b, with the limiting portion 133g located within the limiting groove 11e. This facilitates the positioning of the support piece 13 and further reduces the overall weight of the shoe 100 to improve comfort.

[0049] It is understood that the support piece 13 is not limited to the shape described above, and may be, for example, rectangular, irregular cloud-shaped, etc.

[0050] In some embodiments, the sole body 11 may also form a plurality of holes (not shown) or grooves (not shown) from the upper surface 11a to the lower surface 11b. For example, a plurality of strip grooves (not shown) arranged at intervals along the front-rear direction Y of the sole 10 may be formed corresponding to the forefoot portion 113, and a plurality of holes (not shown) may be formed corresponding to the heel portion 111 and the arch portion 115 for heat dissipation or ventilation.

[0051] In the aforementioned shoe 100, because the sole 10 has a support plate 13 with high hardness and the support plate 13 is provided at least corresponding to the arch portion 115, the support strength of the sole 10 at the arch portion 115 can be improved, thereby enhancing the stability of the sole 10 and the entire shoe 100, and helping to extend the service life of the sole 10 and the shoe 100. Furthermore, the support plate 13 includes a thicker main body 131 and a thinner extension 133, and the main body 131 corresponds to the arch portion 115, further improving the support strength of the sole 10 at the arch portion 115 and providing better torsional resistance. In addition, the sole body 11 has the through hole 11c corresponding to the main body 131, which effectively reduces the weight of the sole 10 while improving the overall design of the shoe 100, thus enhancing the overall comfort of the shoe 100. Furthermore, the through hole 10c, in conjunction with the harder main body 131, helps to reduce wear caused by the interaction between the main body 131 and the sole body 11, and helps to extend the service life of the sole 10 and the entire shoe 100.

[0052] Furthermore, those skilled in the art should recognize that the above embodiments are merely illustrative of this application and are not intended to limit this application. Any appropriate changes and variations made to the above embodiments within the essential spirit and scope of this application fall within the scope of this application's disclosure.
