Patent ID: 8720083

Claim:
A waterproof vapor-permeable shoe, comprising: an upper portion, which delimits the foot insertion region; a sole, made mainly of plastic material, which is provided with at least one region which is diffusely perforated with through holes in the direction of the walking surface; a vapor-permeable or perforated flat element, which is rigidly coupled to the lower portion of said sole on which the tread of said sole is formed or rigidly coupled, said flat element being arranged so as to overlap directly said at least one diffusely perforated region and being adapted to limit the formation of hollows in the foot insertion region at the projection of the holes of said at least one diffusely perforated region; a waterproof vapor-permeable membrane, which is associated with said upper portion and/or with said sole, is arranged above said flat element so as to be superimposed on said at least one diffusely perforated region, and is joined hermetically along its perimeter to the portion of shoe that surrounds said membrane so as to avoid the rise of liquid from said at least one diffusely perforated region and along the perimetric edge of said membrane within the foot insertion region, means for protection against piercing being associated with said membrane and comprising at least said flat element, wherein said sole has a lower portion, which rises laterally so as to provide side walls which delimit the foot insertion region, said at least one diffusely perforated region being formed also on said side walls in order to allow vapor permeation also in a lateral direction, said flat element and said membrane protruding on said side walls so as to be superimposed on the lateral through holes of said diffusely perforated region which is provided laterally.
