Abstract

The utility model relates to a sports shoe sole with functions of internal/external balance transfer and whole-sole shock absorption. The sports shoe sole mainly comprises a middle sole, a protective cover and an outer sole. The middle sole is made of a high-elasticity EVAMD material; and the inner and the outer sides of the middle sole are corrugated in a way that the ridges are oppositely tilted in the forward and backward directions, so that during running, both the inner and the outer sides generate two pressure forces with the same intensity in different directions and the two pressure forces in the forward and the backward directions offset to each other, thereby achieving the whole-sole shock absorbing function. The protective cover is made of a high-elasticity thermoplastic polyurethanes (TPU) material and is positioned in the back sole part of the high-elasticity EVAMD middle sole so as to support the back sole part; high-elasticity TPU balancing and supporting bars are connected on the bottom surface of the protective cover to balance the inner and the outer sides of the middle sole and prevent the imbalance due to the non-uniform stresses on the inner and the outer sides, thereby stabilizing the shoe sole and achieving the effects of internal/external balance transfer and whole-sole shock absorption. The outer sole is made of wear-resistant rubber and has excellent resistance to skid and wear; octopus sucker-simulated functional elements are arranged at the middle part of several main wear-resistant rubber units being in contact with the ground, so as to enhance the skid resistance and the stability during exercise.
