Shoe and shoe sole structure thereof

Abstract

The invention discloses a shoe and a shoe sole structure thereof. The shoe sole structure comprises a large sole, a middle sole and an upper sole which are connected from bottom to top in sequence. A plurality of first grooves which are concave inwards downwards are formed at intervals in sequence in the length direction of a shoe sole on the top face of the middle sole. A first protruding edge is formed between two adjacent first grooves. Upward-inward-concave second grooves arranged corresponding to the first grooves are formed in the bottom face of the upper sole. Second protruding edges which are arranged at intervals corresponding to first protruding edges are formed between the adjacent second grooves. The shoe sole structure has the advantages that the first grooves and the second grooves are designed, so that deformation is large under stress, impact force absorption effect is good, and accordingly damping effect is obvious, a strip-shaped groove, an opening groove and a ventilation hole are designed, so that after deformation of the first grooves and the second grooves, air is compressed, air flow is facilitated, and the ventilation function of the shoe sole is improved.

Description

technical field

[0001] The invention relates to the field of shoes, in particular to shoes and sole structures. Background technique

[0002] As we all know, when people are walking or running, the impact force on the feet of the ground is very large, which can easily lead to injuries to the feet and even the lower limb chain. For this reason, the damping function of sole seems particularly important. At present, the commonly used shock absorption method is to design the sole as follows: the sole is divided into two layers: the outsole and the midsole. The outsole is in contact with the ground and has high wear resistance; the midsole in contact with the foot is made of elastic material. , using the deformation of the elastic material to absorb the above-mentioned ground impact force, so as to achieve the shock absorption function.

[0003] Although the existing sole design can relieve a part of the strong impact force generated by the ground on the feet, the elastic mater...

Examples

Embodiment 1

[0033] Embodiment one: if Figure 2-4 As shown, a plurality of the third grooves 8 and the fourth grooves 9 are arranged along the moving track of the center of gravity of the foot during exercise: the moving track of the center of gravity of the foot is from the outside of the heel, through the middle of the heel, the center of the foot, From the middle of the forefoot to the inside of the forefoot.

[0034] The inner side walls of the third groove 8 and the fourth groove 9 are respectively provided with strip-shaped grooves 13 arranged along the length direction of the sole, and the strip-shaped grooves 13 run through the corresponding first ribs respectively. 5. The design of the bar-shaped groove structure helps the deformation of the first groove and the second groove to compress and promote the flow of air and improve the breathability of the sole.

Embodiment 2

[0035] Embodiment two: if Figure 5-7 As shown, the width of the third groove 8 is almost the same as that of the first rib 5 , and the side walls of the fourth groove 9 communicate with the left and right sides of the midsole 2 .

[0036] For the fifth groove 10 corresponding to the third groove 8 and the fourth groove 9 and the upper bottom 3, the lower surface corresponding to the middle part is respectively provided with the second rib 7 The opening groove 14 is provided directly above the opening groove 14 with a ventilation hole 15 penetrating through the upper surface of the upper bottom. The structural design of the opening groove and the ventilation hole helps the deformation of the first groove and the second groove. Compresses and promotes the flow of air, improving the breathability of the sole.

[0037] The present invention overcomes the technical defect that the shock absorption effect of the sole is not obvious due to insufficient deformation of the sole in th...
