[0002] Vamp is the meaning of the upper, the surface above the sole, the part covering the instep. The vamp lining is the part of the shoe that directly contacts the foot, and it plays an important role in improving the overall quality of the shoe and the wearing experience. Traditionally, the vamp lining is usually made by lining cloth, foam, ankle foam, and reverse lining cloth at the ankle through multiple processes such as needlework, gluing, and turning. The stitching line of the vamp lining may gradually wear out and break due to constant stretching and friction, causing the lining to appear open and loose, which limits the durability of the shoe.

As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items. Example 1

[0024] Referring to Figure 1 , Figure 2 , Figure 4 , Figure 5 , the embodiment provides a one-piece structure of the shoe lining, including upper layer 12, foam interlayer 13 and lower layer 14, the upper layer 12, foam interlayer 13 and lower layer 14 are fixedly connected by die hot pressing, forming a one-piece structure.

[0025] In the technical scheme of the embodiment, the die is a flat plate die, and the shoe lining is a shoe lining with a flat structure as shown in Figure 1 and Figure 2 formed by hot pressing with the flat plate die. In other embodiments, the die is a three-dimensional die, and the shoe lining is a three-dimensional shoe lining consistent with the shape of the shoe tree formed by hot pressing with the three-dimensional die.

[0026] The upper layer 12, the foam interlayer 13 and the lower layer 14 form a plurality of protrusions in the position without hot pressing, the inside of the protrusions is filled with the foam interlayer 13, and the protrusions are protruded towards the upper layer 12 side. The upper layer 12 is in contact with the foot, and the lower layer 14 is used to connect with the vamp. The protrusions are distributed in the toe area, the body area and the heel area of the vamp lining, and the channels for air circulation are formed between the protrusions. When the foot moves, the channels between the protrusions open and close with the movement of the foot, forming a dynamic ventilation effect.

[0027] Specifically, the protrusions include a plurality of ankle protrusions 5 arranged at the top of the heel area 3 and around the toe 11, a plurality of body protrusions 6 arranged at the side of the body area 2 and below the ankle protrusions 5, a plurality of toe top protrusions 8 and a plurality of toe side protrusions 9 arranged at the top and side of the toe area 1 respectively, and a plurality of metatarsophalangeal joint protrusions 7 arranged at the joint of the toe area 1 and the body area 2. By arranging the protrusion structure at the toe, the body and the heel, the protrusion part remains soft and has a certain elasticity, which improves the comfort of the vamp lining and improves the support and cushioning of the foot.

[0028] In the technical scheme of the embodiment, the inside of the ankle protrusion 5 at the toe of the heel area is filled with a foam filling layer 15, the height of the foam filling layer 15 is greater than that of the foam interlayer 13 in other protrusions, and the density of the foam filling layer 15 is higher than that of the foam interlayer 13 in other protrusions. The height of the ankle protrusion 5 is greater than that of other protrusions, so that the toe 11 of the heel area 3 has stronger support and cushioning effect, and the ankle which is easy to be injured is protected. Preferably, the size of the ankle protrusion 5 is greater than that of other protrusions. In the embodiment, three ankle protrusions 5 are arranged on both sides of the toe. When the vamp lining is fixedly installed in the vamp, the front two ankle protrusions 5, the middle two ankle protrusions 5 and the rear two ankle protrusions protect the front, middle and rear positions of the ankle respectively.

[0029] Further, the shape of the protrusion is regular or irregular geometric shape. For example, the body protrusion 6 includes regular shape protrusions such as rhombus, triangle and trapezoidal structure. Of course, in other embodiments, the protrusion can be irregular geometric shape such as leaf shape, petal shape, cloud shape and feather shape.

[0030] In the technical scheme of the embodiment, the metatarsophalangeal joint protrusion 7 is arranged in a strip structure at the metatarsophalangeal joint part. The metatarsophalangeal joint protrusion 7 in the strip structure can naturally bend with the movement of the foot, providing better deformation space for the foot and reducing the restraint on the foot.

[0031] In the technical solution of the embodiment, the upper layer 12 is made of cool Lycra fabric or warm fabric, and the lower layer 14 is made of wear-resistant high-strength nylon fiber fabric.

[0032] Preferably, the shoe lining is uniformly distributed with a plurality of air holes 4, and the air holes 4 penetrate the upper layer 12. In other embodiments, the air holes 4 penetrate the upper layer 12 and the foam layer 13. The arrangement of the air holes enhances the air permeability of the shoe lining. Embodiment 2

[0033] Referring to Figure 3 , Figure 4 , Figure 5 , the remaining components of the embodiment correspond to those of embodiment 1, and will not be described again. The difference from embodiment 1 is that part of the area of the upper layer 1 is made of mesh fabric, and the mesh fabric and the fabric of the upper layer 1 are spliced together by hot pressing to form a mesh fabric area 16 of the upper layer 1 with air permeability, further improving the air permeability of part of the area of the shoe lining. The mesh fabric area of the embodiment is located in the toe area and / or the body area, and is used to improve the air permeability of the toe area and / or the body area.

[0034] The above embodiments are only used to illustrate the technical solutions of the present application, and are not limited thereto. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacements to part of the technical features. These modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
