Abstract: Breathable footwear comprising a waterproofing and breathable portion, at least partially closed so as to identify a containment volume for a foot, wherein the waterproofing and breathable portion is shaped to allow the escape of water or vapour to the outside of the footwear and of the containment volume and to prevent the entry of water or vapour coming from the outside, an upper arranged to cover said waterproofing and breathable portion, wherein the upper is at least partially perforated to facilitate the escape of water or vapour from the waterproofing and breathable portion. The waterproofing and breathable portion is mechanically connected to the upper by means of at least one tape, comprising at least a first flap attached to the waterproofing and breathable portion by means of gluing or heat welding, and comprising at least a second flap fixed to the upper by means of gluing, thermo-forming or sewing.
