SOLE STIFFENING DEVICE, PARTICULARLY FOR SPORTS SHOES

摘要

Sole stiffening device, particularly for sports shoes such as climbing boots, ice boots, trekking boots, soccer shoes, or golf shoes, which is constituted by a semirigid insole (11) that can be temporarily compressed, with the interposition of at least one flexible element (10), inside a box-like mid-sole (5), arranged inside the sole. The device therefore allows to vary the rigidity of the sole simply by varying the position of the semirigid insole with respect to the box-like mid-sole.
