'SOLA UNDERSTANDING A STEAM PERMEABLE ELEMENT AND FOOTWEAR UNDERSTANDING THE SAME'

摘要

Steam-permeable element to be used in the composition of shoe soles, shoe soles and footwear. a vapor permeable element (10, 210, 310, 410, 510, 610) for use in the composition of shoe soles comprising: - a support frame (11, 211, 311, 411) substantially delimiting at least one hole broad bypass (12,512); - a membrane (17, 117) which is water impermeable and water vapor permeable and is arranged on the support frame (11, 211, 311, 411) to cover at least the large through hole (12, 512); - at least one vapor permeable or perforated protective layer (19) for the membrane that is disposed between the support frame (11, 211, 311,411) and the membrane (17, 117) to cover at least the large through hole ( 12, 512). the membrane (17, 117) and the protective layer (19) are joined, at least at their perimeter edges, to each other and to said support frame (11, 211, 311, 411); The protective layer (19), in cooperation with the sole of the sole with which it is associated, is available for contact with the ground during use of the sole.
