The sole of the sports shoe can be mainly divided into three parts from inside to outside, namely an insole, a midsole and an outsole. The "middle sole" is located between the outsole and the insole, is usually made of materials such as EVA or PU, occupies the largest volume of the whole sole, and mainly plays roles of shock absorption, feedback propulsion and stability maintenance. The impact force generated when the sole of the wearer falls to the ground can be absorbed, buffered and dispersed by the insole, so that the cushioning effect is realized, and the damage caused by the overlarge impact force is avoided. In order to provide better support and cushioning effects for shoes, a layer of sole pad with higher mechanical strength is usually added to be sandwiched in the midsole or between the outsole and the midsole when the shoes are manufactured.

In the conventional shoe, a high Stress (Stress) is locally formed at the sole pad due to the impact force, and the sole pad is broken or cracked. Therefore, if the local high stress of the sole pad can be reduced and the elasticity can be kept, the sole pad has both functionality and durability.
