Description

Technical Field

[0001] The present application relates to the technical field of sports shoes, and in particular to a heel structure and sports shoes for preventing heels from falling off. Background Art

[0002] The inner wall of the existing sports shoes at the back heel has poor three-dimensionality, which makes it poorly adapted to the back heel of the wearer. During walking and exercise, it is impossible to provide sufficient friction and limit, which may easily cause the heel to fall off. Utility Model Content

[0003] In order to reduce the possibility of heel falling off during wearing, the present application provides a heel structure and sports shoes that can prevent heel falling off.

[0004] The present application provides a heel structure and sports shoes that prevent heel drop, which adopt the following technical solutions:

[0005] A heel structure for preventing heels from falling off comprises a mesh, a first foam layer and suede breathable leather, wherein the first foam layer is located between the mesh and the suede breathable leather, the first foam layer is provided with two heterosexual foams, the two heterosexual foams are symmetrically arranged, a gap is provided between the two heterosexual foams, and the length direction of the heterosexual foams is parallel to the length direction of the first foam layer.

[0006] By adopting the above technical solution, a heterosexual foam is arranged on the first foam layer, the heterosexual foam protrudes from the first foam layer, and there is a gap between the two heterosexual foams. During wearing, the wearer's Achilles tendon is stuck in the gap between the two heterosexual foams, thereby reducing the possibility of heel falling off during walking.

[0007] Optionally, a first extension portion is provided at one end of the heterosexual foams that are close to each other, and the first extension portion extends upward.

[0008] By adopting the above technical solution, the foot will have recessed parts on both sides of the Achilles tendon, and the first extension parts are arranged on the heterogeneous foam in turn. When worn, the two first extension parts are respectively clamped in the recessed parts on both sides of the Achilles tendon, thereby further reducing the possibility of heel falling off.

[0009] Optionally, the connection between the heterosexual foam and the first extension portion is an arc-shaped transition connection, and the arc-shaped opening faces upward.

[0010] By adopting the above technical solution, the connection is set to an arc-shaped transition, making the connection smoother, thereby improving the comfort when wearing.

[0011] Optionally, an arc-shaped groove is provided on the upper edge of the transverse section of the heterosexual foam, and the arc-shaped groove extends to an end of the heterosexual foam away from the first extension portion.

[0012] By adopting the above technical solution, since there are protruding bone joints on both sides of the ankle of the human foot, an arc groove is provided on the transverse section of the special-shaped foam to be adapted to the bone joints, thereby further improving the wearing comfort.

[0013] Optionally, the special-shaped foam is located on the upper part of the first foam layer.

[0014] Optionally, TPU strips are evenly distributed on the side of the suede breathable leather away from the first foam layer, and the TPU strips are thermally pressed on the suede breathable leather.

[0015] By adopting the above technical solution, TPU strips are provided on the suede breathable leather. The TPU strips can provide a certain frictional force and unevenness, thereby increasing the frictional force between the wearer's foot and the suede breathable leather, and thus reducing the possibility of heel slipping.

[0016] Optionally, a cavity is formed in the special-shaped foam, activated carbon particles are filled in the cavity, and a plurality of air holes communicating with the cavity are formed on the surface of the special-shaped foam away from the first foam layer.

[0017] By adopting the above technical solution, activated carbon particles are provided in the special-shaped foam. The activated carbon particles can deodorize the air in the shoe cavity, thereby improving the wearing comfort.

[0018] An anti-heel-slipping sports shoe includes the above-mentioned heel structure and a shoe upper body. The shoe upper body has a shoe cavity inside, and the shoe upper body is provided with an insertion opening for the wearer's foot to extend into the shoe cavity. The heel structure is fixedly installed on the inner wall of the shoe cavity at the insertion opening.

[0019] In summary, the present utility model has the following beneficial effects:

[0020] 1. A special-shaped foam is provided on the first foam layer to increase the convexity, and the shape of the special-shaped foam is adapted to the wearer's rear heel to catch the concave position of the ankle rear heel of the foot, thereby playing a role in limiting and preventing heel slipping;

[0021] 2. There are recessed parts on both sides of the foot at the Achilles tendon. A first extension part is provided on the special-shaped foam in sequence. When wearing, the two first extension parts are respectively caught in the recessed parts on both sides of the Achilles tendon, thereby further reducing the possibility of heel slipping.

[0028] This embodiment of the application discloses an anti-heel-drop heel structure, referring to Figure 1 the figure, which includes a mesh fabric 1, a first foam layer 2 and a suede breathable leather 4. The first foam layer 2 is located between the mesh fabric 1 and the suede breathable leather 4, and the first foam layer 2 is fixedly connected to the mesh fabric 1. The first foam layer 2 is provided with two special-shaped foams 3. The two special-shaped foams 3 are symmetrically arranged along the length direction of the mesh fabric 1. There is a gap between the two special-shaped foams 3. The length direction of the special-shaped foam 3 is parallel to the length direction of the first foam layer 2. The suede breathable leather 4 is fixedly connected to the first foam layer 2 to cover the two special-shaped foams 3.

[0029] Referring to Figure 1 the figure, the ends of the special-shaped foams 3 close to each other are provided with first extension parts 31. The first extension parts 31 extend upward. There will be recessed parts on both sides of the foot at the Achilles tendon. The first extension parts 31 are successively arranged on the special-shaped foams 3. When wearing, the two first extension parts 31 are respectively clamped in the recessed parts on both sides of the Achilles tendon, thereby further reducing the possibility of heel drop.

[0030] Referring to Figure 1 the figure, the connection between the special-shaped foam 3 and the first extension part 31 is an arc-shaped transition connection and the arc opening faces upward. The upper edge of the transverse section of the special-shaped foam 3 is provided with an arc-shaped groove 32. The arc-shaped groove 32 extends to the end of the special-shaped foam 3 far from the first extension part 31, and the special-shaped foam 3 is located above the first foam layer 2. Since there are protruding joints on both sides of the ankle of the human foot, an arc-shaped groove 32 is provided on the transverse section of the special-shaped foam 3 to match the joints, thereby further improving the wearing comfort.

[0031] Referring to the figure, TPU strips are evenly distributed on the side of the suede breathable leather away from the first foam layer. The TPU strips are hot-pressed on the suede breathable leather. TPU strips are provided on the suede breathable leather. The TPU strips can provide a certain frictional force and unevenness, thereby increasing the frictional force between the wearer's foot and the suede breathable leather, and thus reducing the possibility of heel drop.
