Abstract

A sole for sports shoes is proposed which has improved shock absorbing capability when landing, and provides a repulsion force when kicking. Cushioning members are mounted in the recesses formed in the sole plate. Each cushioning member has a pair of sheets adhered together at spacings to form a plurality of chambers. The chambers are filled with a gel to inflate them. Air chambers are formed between the gel filling chambers.
