Abstract
Abstract Footwear adapted to absorb perspiration from the foot and keep the foot substantially dry includes a layer of sponge material (2, 21) with open intercommunicating cells, which is substantially non elastically deformable under the compressive stress due to the weight of the person wearing the footwear. The layer of sponge material is intended to be interposed between the sole of the footwear and the foot of the user, and is preferably constituted by a highly porous sponge metal. The invention is particularly useful in the manufacture of sports footwear.
