Abstract
A sole for footwear provided with an aeration system to permit the fresh air to reach the entire lower foot surface of the user, is described. Accordingly, a perforated portion (5) has been provided in the bridge area which on its inner face is in fluid connection with the sole and heel areas, where a circuit has been formed for air flow, thanks to recesses or notches (4,5) made in the respective economisers (2,3). An internal housing permits the arrangement of a Goretex plate intended to allow moisture circulation in a single direction, from inside to outside.
