Detailed description of the invention

In order to technical scheme is explained further, come this below by specific embodiment Invention is described in detail.

As it is shown in figure 1, the present invention relates to a kind of sole 1 shock-damping structure, including being formed at sole 1 half sole and/or rear several damper elements 3 slapping region, these some damper elements 3 can be single Solely it is formed at half sole region, it is also possible to slap region after being individually formed at, it is also possible to be concurrently formed at Half sole region and rear palm region.

The central inventive point of the present invention is to be the improvement to damper element 3, each damper element 3 are respectively provided with shock-absorbing main bodies 32 and are coated on the outsourcing edge 31 of shock-absorbing main bodies 32 lateral margin, and this subtracts Shake main body 32 and outsourcing edge 31 are the most vertically extending with trampling that support shoes are subjected to Power.

This shock-absorbing main bodies 32 uses the first elastomeric material to make, and this outsourcing edge 31 uses the second bullet Property material make, the elasticity of this first elastomeric material is better than the second elastomeric material, and this is second elastic The ageing resistace of material is better than the first elastomeric material.In the specific implementation, this first elastic material Material selects EVA, TPE or rubber, and this second elastomeric material selects TPU or nylon, this TPU Refer to thermoplastic polyurethane, its be use Shooting Technique one-body molded go out described outsourcing edge 31.
