Problems solved by technology

[0002] In the prior art, the special insoles of sports shoes are generally designed as a plane. Although such a structure is simple, because the heel and the sole of the soles of people's feet are not on the same plane as the arch of the foot, this kind of insoles will not be on the same plane when used. Especially when people are exercising vigorously, the stress on each part of the insole is unbalanced, which will cause a large shear stress inside the insole, thus seriously affecting the service life of the insole
In order to solve this technical problem, usually only by improving the material of the insole to ensure that the insole has sufficient service life, but this increases the cost

Abstract

The invention provides a sports insole, which comprises a main body, wherein the main body consists of a heel part (1), an instep part (2), a sole part (3) and a toe part (4). The sports insole is characterized in that: the bottom face of the main body is flat; and all upper parts are in a convex-concave shape matched with the shape of the sole. The insole reduces shearing stress greatly, has a long service life, and wears comfortable.

Description

technical field [0001] The invention relates to an insole, in particular to a sports insole. Background technique [0002] In the prior art, the special insoles of sports shoes are generally designed as a plane. Although such a structure is simple, because the heel and the sole of the soles of the general people are not on the same plane as the arch of the foot, this insole is in use. Especially when people are exercising violently, the unbalanced stress of each part of the insole will cause a large shear stress inside the insole, thus seriously affecting the service life of the insole. In order to solve this technical problem, usually only by improving the material of the insole to ensure that the insole has sufficient service life, but this increases the cost. Contents of the invention [0003] The object of the present invention is to provide a sports insole with a long service life in view of the problems of the prior art. [0004] The object of the present invention...
