Description

Sports shoe midsole and outsole structure

Technical Field

The application belongs to the field of sports shoes, and particularly relates to a middle sole and an outsole structure of a sports shoe.

Background

The sole structure of the existing mainstream common sports shoes is mainly made of EVA or other damping materials for making the midsole and rubber for making the outsole. When people wear the sports shoes to do sports, the midsole material is required to have four functions of cushioning, supporting, extending, softness and easy curling. But since these several characteristics are contradictory in many scenarios: for example, when the sole falls to the ground, the midsole is required to be soft enough to absorb and share the impact force, and meanwhile, the sole is required to be supported laterally enough to cause eversion; when the sole is started from the ground, the midsole is required to have enough longitudinal supporting force in order to have quick response, and meanwhile, the human sole needs to have transverse softness and heel when the tarsal bones and the metatarsal bones are sequentially bent to the phalanges to exert force in the ground-leaving action. The mere use of one material and construction must therefore be a great compromise in the performance of the sports shoe.
