Abstract
A waterproofed and breathable sole for shoes, which includes a tread made of leather, or similar breathable and water-permeable material, at least partially covered in an upward region by a membrane made of a material that is breathable and impermeable to water and is perimetrically joined to the tread with the interposition of a sealant or by direct adhesion thereof so as to provide a seal.
Claims16
A waterproofed and breathable sole for shoes, comprising:
- a tread made of leather, or similar breathable and water-permeable material, which is entirely covered in an upward region by a membrane made of a material that is breathable and impermeable to water and is joined at least perimetrically to the tread with the interposition of a sealant, said membrane being shaped perimetrically complementarily to the edge of said tread such that said membrane and said tread have the same perimetric dimensions.
A method for producing a waterproofed and breathable sole for shoes, comprising the steps of:
- providing a tread made of leather, or similar breathable and a water-permeable material,
- providing a membrane made of a material that is breathable and impermeable to water and that is shaped perimetrically complementarily to the edge of said tread such that said membrane and said tread have the same perimetric dimensions,
- spreading sealant on an upper part of the tread, at least at a position of an edge of the membrane;
- applying the membrane on the tread while the sealant is still moist such that the membrane entirely covers the upward region of the tread,
- performing catalysis selectively, either at high temperature, or at a lower temperature with addition of reaction promoters;
- and
- performing cooling.
