Device for differentiating the torsional stress reactions of shoes for soccer or similar sports

摘要

A device for differentiating the torsional stress reactions of shoes for soccer or similar sports comprising a substantially flat kevlar element (16) which is integrated into an insole (14) made of polymeric material with a rear part (15) shaped like a heel containment cup. The element (16) surrounds the heel region (17) starting from the part (18) that corresponds to the outside of the foot and affects the metatarsal region (19) by widening in a transverse direction.
