[0017] Implementations of the present disclosure will now be described, by way of embodiments, with reference to the above figures. The embodiments are obviously a portion but not all of the embodiments of the present disclosure.

[0018] Unless otherwise defined, the technical terms used in the present disclosure have the same meanings as those commonly understood by those skilled in the art. The terms used in the present disclosure are for describing specific embodiments but not intended to limit the scope of present disclosure. In addition, technical features involved in different embodiments of this application that are described below may be combined as long as they do not conflict with each other.

[0019] Referring to FIG. 1, a footwear 100 is provided according to an embodiment of the present disclosure. The footwear 100 includes a sole 10 and an upper 20 connected to the sole 10. The upper 20 and the sole 10 cooperatively define a receiving cavity (not shown) for receiving a wearer's foot. The upper 20 and the sole 10 may be connected to each other in any desired manner, including in manners known and used in the footwear articles (such as by one or more of adhesives or cements, stitching or sewing, mechanical connectors, etc.). The upper 20 may be made of any desired material in any desired construction or manner. For example, at least a portion of the upper 200 may be formed as a woven textile component, a knitted textile component, a natural leather component, a synthetic leather component, or a polymeric component (e.g., thermoplastic polyurethane, TPU).

[0020] Referring to FIGS. 1 and 2, the sole 10 includes a sole body 11 and a support sheet 13 fixed to the sole body 11. In at least one embodiment, the sole body 11 and the support sheet 13 may be fixed by adhesion. In some embodiments, the sole body 11 and the support sheet 13 may also be fixed by interlocking, or by other means such as but not limited to fixing the two by shoe nails.

[0021] The sole body 11 is divided into a rearfoot portion 111, a forefoot portion 113 and an arch portion 115 connecting the rearfoot portion 111 and the forefoot portion 113.

[0022] The sole body 11 has a thickness direction Z and includes an upper surface 11a, a lower surface 11b facing away from the upper surface 11a in the thickness direction Z, and a through hole 11c penetrating the upper surface 11a and the lower surface 11b. The through hole 11c is located in the arch portion 115 and extends through the arch portion 115 in the thickness direction Z. In at least one embodiment, the sole body 11 can be formed by stacking a midsole and an outsole. It can be understood that at this time, the upper surface 11a is a surface of the midsole facing away from the outsole, the lower surface 11b is a surface of the outsole facing away from the midsole, and the through hole 11c extends through the midsole and the outsole. The midsole and the outsole may be designed to be separable or integrally formed.

[0023] Referring to FIGS. 3 to 6, a recess 11d is recessed from the upper surface 11a at least corresponding to the arch portion 115 towards the lower surface 11b, and the recess 11d is in communication with the through hole 11c.

[0024] A hardness of the support sheet 13 is higher than a hardness of the sole body 11. When the support sheet 13 is fixed to the sole body 11, the support strength of an area of the sole body 11 corresponding to the support sheet 13 can be enhanced.

[0025] The support sheet 13 includes a main body 131 and an extension portion 133 extending from the main body 131. A thickness of the main body 131 is greater than a thickness of the extension portion 133, and a side of the main body 131 is flush with a side of the extension portion 133.

[0026] The main body 131 is accommodated in the through hole 11c, and the extension portion 133 is accommodated in the recess 11d. Moreover, the side of the main body 131 flush with the extension portion 133 faces away from the lower surface 11b, that is, the side of the main body 131 flush with the extension portion 133 faces upwards. It can be understood that the extension portion 133 can be designed to conform to a shape of the recess 11d.

[0027] In the above-mentioned footwear 100, since the sole 10 has the support sheet 13 with higher hardness and the support sheet 13 is at least arranged corresponding to the arch portion 115, the support strength of the sole 10 at the arch portion 115 can be enhanced, thereby enhancing the stability of the sole 10 and the stability of the entire footwear 100, which is beneficial to prolonging the service life of the sole 10 and the service life of the entire footwear 100. Moreover, the support sheet 13 includes a thicker main body 131 and a thinner extension portion 133, and the main body 131 corresponds to the arch portion 115, thereby further enhancing the support strength of the sole 10 at the arch portion 115 and having better anti-twist performance. Additionally, the sole body 11 is provided with the through hole 11c corresponding to the main body 131, which not only enhances the overall design sense of the footwear 100 but also effectively reduces the weight of the sole 10, thereby improving the overall comfort of the footwear 100. Moreover, the through hole 11c cooperates with the harder main body 131, which is beneficial to reducing the abrasion caused by the interaction between the main body 131 and the sole body 11, and is beneficial to prolonging the service life of the sole 10 and the service life of the entire footwear 100.

[0028] In some embodiments, the support sheet 13 may be but is not limited to a carbon plate, a nylon plate or a thermoplastic polyurethane plate. It can be understood that the hardness of the carbon plate, the nylon plate or the thermoplastic polyurethane plate needs to be higher than the hardness of the sole body 11. In some embodiments, the carbon plate may include a first carbon fiber layer, a foam layer and a second carbon fiber layer stacked in sequence, which is conducive to enhancing the support strength and the stability while improving the foot feel to enhance the comfort. In some embodiments, the carbon plate is not limited to the above structure, for example, it may only be a carbon fiber layer.

[0029] In the thickness direction Z of the sole 10, a height of the main body 131 may be in a range of 5 mm to 15 mm. An end of the main body 131 facing away from the upper surface 11a is located in the through hole 11c, that is, the main body 131 does not extend out of the sole body 11 from the through hole 11c. The above height range of the main body 131 is conducive to ensuring the support strength and the anti-twist property of the arch portion 115.

[0030] In some embodiments, a depression 135 may be recessed from the side of the main body 131 that is flush with the extension portion 133 towards the lower surface 11b, and the depression 135 includes an opening 135a on the side of the main body 131 flush with the extension portion 133. The setting of the depression 135 can reduce the weight of the main body 131 when the main body 131 enhances the support strength and the stability of the sole 10, thereby reducing the overall weight of the footwear 100, so that the comfort of the footwear is improved.

[0031] The opening 135a may be a rhombus, and each cross-section of the depression 135 in a direction where the opening 135a is located is also a rhombus. In at least one embodiment, each corner of the rhombus is rounded. The design of the rounded corners is conducive to reducing the concentration of stress.

[0032] The depression 135 is defined by an inner wall 135b, the inner wall 135b may be an arc surface, and an area of the cross-section of the depression 135 in the direction where the opening 135a is located closer to the opening 135a is greater than an area of the cross-section of the depression 135 in the direction where the opening 135a is located further away from the opening 135a. The above design is conducive to allowing the footwear 100 to roll more smoothly and naturally in a front-back direction.

[0033] A side of the support sheet 13 facing away from the lower surface 11b may be flush with the upper surface 11a, which is conducive to maintaining the overall shape of the upper surface 11a of the sole 10 and ensuring the comfort.

[0034] In some embodiments, thicknesses of any two areas of the extension portion 133 are consistent. In some embodiments, a thickness of the extension portion 133 may gradually decrease from an end of the extension portion 133 connected to the main body 131 to an end of the extension portion 133 away from the main body 131, that is, the extension portion 133 becomes thinner and thinner outward from the main body 131. Correspondingly, a depth of the recess 11d gradually decreases from an end of the recess 11d connected to the through hole 11c to an end of the recess 11d away from the through hole 11c. The above design is conducive to enhancing the support strength and the stability through the extension portion 133 while ensuring the rebound effect and the flexibility of deformation of the sole 10, thereby improving the comfort.

[0035] A thickness of a thinnest part of the extension portion 133 may be greater than or equal to 1.3 mm, which is conducive to ensuring the support strength of the support sheet 13.

[0036] Referring to FIGS. 2 to 3, the support sheet 13 may be approximately X-shaped. Specifically, the extension portion 133 may include a first part 133a, a second part 133b, a third part 133c and a fourth part 133d respectively extending from the main body 131. The first part 133a and the second part 133b are arranged at an angle and respectively extend towards the forefoot portion 113, while the third part 133c and the fourth part 133d are arranged at an angle and respectively extend towards the rearfoot portion 111. Thus, when observing the sole 10 from top to bottom, the support sheet 13 is approximately X-shaped.

[0037] Referring to FIG. 7, the recess 11d may also extend to the forefoot portion 113. Correspondingly, the extension portion 133 of the support sheet 13 extends to the forefoot portion 113. When the user is running, the above structure can provide better rebound and rolling push effect when the footwear deforms, thereby enhancing the comfort of the footwear.

[0038] Referring to FIG. 7, in some embodiments, the extension portion 133 may include a forefoot area 133e located in the forefoot portion 113. In at least one embodiment, the forefoot area 133e may further include two or three spaced grooves 133f, each of the two or three spaced grooves 133f recesses from an end of the forefoot area 133e facing away from the arch portion 115 towards the arch portion 115, thereby forming multiple branches at the end of the forefoot area 133e, which increases the flexibility of the deformation of the forefoot area 133e of the support sheet 13 while enhancing the support strength and the stability of the footwear 100 through the support sheet 13, thereby improving the overall comfort of the shoe 100.

[0039] In some embodiments, a side of the forefoot area 133e facing the lower surface 11b may protrude a limiting part 133g. Correspondingly, the forefoot portion 113 further includes a limiting slot 11e penetrating the upper surface 11a and the lower surface 11b, and the limiting part 133g is located in the limiting slot 11e, which is conducive to the positioning of the support sheet 13 and further reduces the overall weight of the footwear 100 to improve comfort.

[0040] It can be understood that the support sheet 13 is not limited to the above shape, for example, it may be but not limited to rectangular, irregular cloud-shaped, etc.

[0041] In some embodiments, the sole body 11 may further include several holes (not shown) or grooves (not shown in the figure) recessed from the upper surface 11a to the lower surface 11b. For example, multiple strip-shaped grooves (not shown) arranged and spaced apart from each other in the front-back direction Y of the sole 10 may be formed corresponding to the forefoot portion 113, and multiple holes (not shown) may be formed corresponding to the rearfoot portion 111 and the arch portion 115, which are used for heat dissipation or exhaust.

[0042] In the above-mentioned footwear 100, since the sole 10 has the support sheet 13 with higher hardness and the support sheet 13 is at least arranged corresponding to the arch portion 115, the support strength of the sole 10 at the arch portion 115 can be enhanced, thereby enhancing the stability of the sole 10 and the stability of the entire footwear 100, which is beneficial to prolonging the service life of the sole 10 and the service life of the entire footwear 100. Moreover, the support sheet 13 includes a thicker main body 131 and a thinner extension portion 133, and the main body 131 corresponds to the arch portion 115, thereby further enhancing the support strength of the sole 10 at the arch portion 115 and having better anti-twist performance. Additionally, the sole body 11 is provided with the through hole 11c corresponding to the main body 131, which not only enhances the overall design sense of the footwear 100 but also effectively reduces the weight of the sole 10, thereby improving the overall comfort of the footwear 100. Moreover, the through hole 11c cooperates with the harder main body 131, which is beneficial to reducing the abrasion caused by the interaction between the main body 131 and the sole body 11, and is beneficial to prolonging the service life of the sole 10 and the service life of the entire footwear 100.

[0043] Even though information and advantages of the present embodiments have been set forth in the foregoing description, together with details of the structures and functions of the present embodiments, the disclosure is illustrative only. Changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the present embodiments to the full extent indicated by the plain meaning of the terms in which the appended claims are expressed.
