Abstract
A waterproof and breathable sole for shoes, including a lower layer, including at least one large through hole. Above the lower layer, a mesh is provided, arranged to overlap at least the large through hole. A membrane made of a material that is impermeable to water and permeable to water vapor is associated in an upward region with respect to the mesh at least at the large hole. The membrane is joined hermetically at least perimetrically to at least one component of the sole so as to avoid liquid rise through the perimeter of the large hole. A perforated upper layer is arranged above the membrane. The lower layer is overmolded on the mesh and partially incorporates the mesh.
