Abstract
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.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
166 words
A shoe comprising a sole plate formed with a recess, and a shock absorbing cushioning member having a pair of sheets adhered together at spacings to form between said spacings a plurality of spaced gel filled chambers and an annular gel filled chamber around said spaced chambers, each of said gel filled spaced chambers and said annular gel filling chamber being filled with a non-elastically deformable gel, said recess being of a depth substantially equal to the thickness of said spaced gel filled chambers and said annular chamber, said cushioning member being received in said recess in said sole plate with air filled spaces between and surrounding said gel filled spaced chambers and said gel filled annular chamber, said gel filled chambers being deformed and said air in said air spaces between and surrounding said gel filled chambers being compressed when shock forces are applied to said cushioning member, said compressed air expanding and reforming said deformed gel filled chambers when said shock forces are repulsed.
Claim 2
Dependent Claim
166 words
A shoe comprising a sole plate formed with a recess, and a shock absorbing cushioning member having a pair of sheets adhered together at spacings to form between said spacings a plurality of spaced gel filled chambers and an annular gel filled chamber around said spaced chambers, each of said gel filled spaced chambers and said annular gel filling chamber being filled with a non-elastically deformable gel, said recess being of a depth substantially equal to the thickness of said spaced gel filled chambers and said annular chamber, said cushioning member being received in said recess in said sole plate with air filled spaces between and surrounding said gel filled spaced chambers and said gel filled annular chamber, said gel filled chambers being deformed and said air in said air spaces between and surrounding said gel filled chambers being compressed when shock forces are applied to said cushioning member, said compressed air expanding and reforming said deformed gel filled chambers when said shock forces are repulsed.
