Improved vapor-permeable footwear

摘要

It has been found that inserting a layer of a micro-capillary felt (7) in the space defined between the outsole (2) and midsole (3) allows footwear to be provided with a soft plantar zone and a very flexible outsole (2) so as to contribute to the evacuation of vapor resulting from evaporation of perspiration of the foot and enhance comfort for the user while still having the advantages derived from the application of the vapor-permeable and water-tight material (6). More specifically, the footwear according to the invention has an outsole (2), a midsole (3), and an upper. Between the midsole (3) and outsole (2) is a layer of a liquid water-impervious and water vapor-permeable material (6). The outsole (2) and the midsole (3) can have a plurality of holes (4,4') for letting vapor from the interior migrate to the outside of the footwear.
