Insole structure

Abstract

An insole structure comprises an upper sole body and a lower sole body. The upper sole body is a soft flexible fabric layer. A positioning element is arranged on the bottom face of the upper sole body. The body of the lower sole body is a foaming body composed of independent bubbles with unconnected air chambers. An antiskid element is arranged on the bottom face of the lower sole body. A bindingelement is arranged on the top face of the lower sole body. The positioning element of the upper sole body is connected with the binding element on the lower sole body, so the upper sole body is positioned on the lower sole body, the functions of supporting, buffering, shock absorbing and pressure relieving are realized through the lower sole body, the function of comfortable stepping is realizedthrough the upper sole body, and when the upper sole body gets dirty, a user only needs to replace the upper sole body instead of changing the whole insole.

Description

technical field [0001] The present invention relates to an insole structure, especially an insole structure with a detachable upper insole. When the upper insole is dirty, it is only necessary to replace the upper insole or clean the upper insole without cleaning or discarding the entire insole. . Background technique [0002] It is known that the main appeal of functional insoles is nothing more than the support of the arch of the foot, or the design of breathable and anti-beriberi, or the combination of shock-absorbing and pressure-absorbing materials to reduce the pressure on the soles of the feet. All insoles that appeal to functionality are relatively ordinary in terms of cost. Insoles are expensive, and in order to make functional insoles, the production process usually increases, resulting in cumbersome production, and in order to achieve one of the functions, it is usually necessary to abandon other functions, such as: breathable insoles, usually the supporting effec...

AI Technical Summary

Problems solved by technology

[0004] Although the conventional insole has multiple functions, the upper fabric layer cannot be removed from the foam layer of the main body, because the upper fabric layer and the foam layer are tightly bonded, once the upper fabric layer is damaged or dirty, Users usually can only discard the insole and replace it again, or scrub the entire insole. In this way, the foam layer will absorb moisture and get damp, reducing the service life of the insole

[0005] Furthermore, it is very cumbersome and time-consuming to make the insoles of multi-layer materials in order to keep the surface smooth. Especially when adding other functions, the structure must be improved. Because of the cumbersome manufacturing process, It will inevitably consume a lot of man-hours, leading to an increase in cost, and relatively causing consumers to spend more to purchase, resulting in an economic burden on consumers
