Description

Technical Field

[0001] This utility model relates to a durable multi-layer slipper sole structure, belonging to the field of slipper soles. Background Technology

[0002] Slippers are a type of shoe with an open heel and a toe box. They are usually flat and do not require laces. They are often made of lightweight and soft materials such as leather, plastic, or fabric. Types of slippers vary depending on the occasion and intended use.

[0003] To increase the friction between the sole and the foot, existing slippers often have a frosted surface or anti-slip raised structures on the top. However, the anti-slip raised structures can cause discomfort to the feet, while the frosted surface has poor water drainage, which greatly reduces the anti-slip effect when wading in water. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a durable multi-layer slipper sole structure to solve the problem that existing slipper soles have a frosted surface or anti-slip protrusions on the top surface in order to increase the contact friction with the foot. The anti-slip protrusions can easily cause discomfort to the foot, while the frosted surface has poor water drainage, resulting in a significant reduction in anti-slip effect when wading in water.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a durable multi-layer slipper sole structure, comprising an outsole, a midsole, and an insole; the midsole is connected to the top surface of the outsole; and the insole is fixedly embedded in the top surface of the midsole.

[0006] The heel section of the midsole is provided with several integrally formed cushioning ridges from top to bottom, and the front part of the cushioning ridges extends and wraps around both sides of the midsole.

[0007] The outer side of the insole is provided with a shoelace insertion slot, and the top surface of the insole is composed of a frosted area and a smooth area, wherein the middle edge of the frosted area is provided with an arch part corresponding to the arch part of the foot.

[0008] The smooth area includes at least two grooves spaced apart, with a smooth end face between each pair of grooves.

[0009] Furthermore, to improve the buffer deformation effect, the outer side of the buffer convex band has an arc.

[0010] Furthermore, to facilitate assembly, the top of the midsole is provided with an assembly slot that fits and is fixed to the inner insole.

[0011] Furthermore, in order to arrange drainage according to the structure of the foot, the smooth area is provided in two places, one of which is inclined at the forefoot of the insole, and the other is connected at one end to the edge of the forefoot of the insole and at the other end to the edge of the heel of the insole.

[0012] Furthermore, in order to achieve efficient drainage, the smooth area has an arc-shaped or wavy structure.

[0013] Furthermore, in order to improve the anti-slip effect, an anti-slip groove is provided in the center of the bottom surface of the outsole. Several edge anti-slip protrusions are provided around the anti-slip groove, and several central anti-slip protrusions are provided inside the anti-slip groove. The size of the central anti-slip protrusions is monotonically increasing along the forefoot direction of the outsole.

[0014] Furthermore, in order to squeeze out the water from the ground, both the edge anti-slip protrusion and the center anti-slip protrusion are provided with at least one drainage groove.

[0015] The beneficial effects of this utility model are: the multi-layer slipper sole structure formed by the outsole, midsole, and insole, together with several cushioning convex strips on the midsole, effectively improves the overall durability. When the foot acts on the multi-layer slipper sole structure, the abrasive area and the smooth area are reasonably positioned. The abrasive area is responsible for contacting the foot and ensuring anti-slip performance, while the smooth area, through the grooves and smooth end face, can effectively drain the liquid flowing into the abrasive area out of the sole, preventing it from affecting the anti-slip effect.

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments. Example 1

[0022] Please see Figure 1 , Figure 2 , Figure 3 This utility model provides a durable multi-layer slipper sole structure technical solution: its structure includes an outsole 1, a midsole 2, and an insole 3; the midsole 2 is connected to the top surface of the outsole 1; the insole 3 is fixedly embedded in the top surface of the midsole 2;

[0023] The bottom and top surfaces of the midsole 2 are connected to the outsole 1 and the insole 3 by adhesive bonding. The outsole 1 is made of one of the following materials: rubber, thermoplastic rubber, or PVC. The midsole 2 is made of EVA material. The insole 3 is made of one of the following materials: silicone, microfiber leather, or EVA foam.

[0024] like Figure 1 As shown, the heel portion of the midsole 2 is provided with several integrally formed cushioning convex bands 21 from top to bottom, and the front part of the cushioning convex bands 21 extends and wraps around both sides of the midsole 2.

[0025] The outer side of the insole 3 is provided with a shoelace insertion slot 31. The top surface of the insole 3 is composed of a frosted area 32 and a smooth area 33. The middle edge of the frosted area 32 is provided with an arch part 34 corresponding to the arch part of the foot.

[0026] The frosted area 32 is manufactured by laser engraving a 120-200 grit sandblasted texture on the surface of a steel mold. This sandblasted area 32 is formed after the steel mold presses against the top surface of the inner bottom 3.

[0027] like Figure 2 As shown, the smooth area 33 includes at least two grooves spaced apart, with a smooth end face between each pair of grooves.

[0028] To improve the buffering effect, the outer side of the buffer convex band 21 is curved.

[0029] To facilitate assembly, the top of the midsole 2 is provided with an assembly slot that fits and is fixed to the inner bottom 3.

[0030] like Figure 2 As shown, in order to arrange drainage according to the structure of the foot, two smooth areas 33 are provided at intervals. One smooth area 33 is inclined at the forefoot of the insole 3 to avoid contact with the toes. The other smooth area 33 is connected at one end to the edge of the forefoot of the insole 3 and at the other end to the edge of the heel of the insole 3, and is distributed in the concave arc surface of the foot.

[0031] For efficient drainage, the smooth area 33 has a wavy structure.

[0032] like Figure 3As shown, in order to improve the anti-slip effect, an anti-slip groove 11 is provided in the middle of the bottom surface of the outsole 1. Several edge anti-slip protrusions 12 are provided around the anti-slip groove 11, and several central anti-slip protrusions 13 are provided inside the anti-slip groove 11. The size of the several central anti-slip protrusions 13 is monotonically increasing along the forefoot direction of the outsole 1.

[0033] Among them, the edge anti-slip protrusion 12 and the center anti-slip protrusion 13 are one of the following structures: conical, square, or circular with arc-shaped ends, preferably conical.

[0034] In order to squeeze out the water from the ground, both the edge anti-slip protrusion 12 and the center anti-slip protrusion 13 are provided with at least one drainage groove 14.

[0035] The outsole 1, midsole 2, and insole 3, together with several cushioning convex strips 21 on the midsole 2, form a multi-layer slipper sole structure, which effectively improves the overall durability. When the foot acts on the multi-layer slipper sole structure, the abrasive area 32 and the smooth area 33 are properly positioned. The abrasive area 32 is responsible for contact with the foot to ensure anti-slip performance, while the smooth area 33, through the grooves and smooth end face, can effectively drain the liquid flowing into the abrasive area 32 to the outside of the sole, preventing it from affecting the anti-slip effect.
