Abstract
An insert for vapor-permeable and waterproof soles, which has a stratified and cohesive monolithic sheet-like structure, which includes a plurality of functional layers made of a polymeric material that is impermeable to water in the liquid state and permeable to water vapor. At least one functional portion of the insert for soles has such a thickness as to give it a penetration resistance of more than approximately 10 N, assessed according to the method presented in chapter 5.8.2 of the ISO 20344-2004 standard.
Claims31
An insert for vapor-permeable and waterproof soles, having a stratified and cohesive monolithic sheet-like structure, comprising:
- a plurality of waterproof and vapor permeable functional layers, each of the functional layers being made of a polymeric material that is permeable to water vapor and impermeable to water in the liquid state such that no water through passages are present in each of the functional layers, and water in the liquid state is prevented from passing in each of the functional layers from a first side surface of a respective functional layer to a second side surface of the respective functional layer opposite the first side surface;
- and
- at least one functional portion of said insert for soles having such a thickness as to give it a penetration resistance of more than approximately 10 N, assessed according to the method presented in chapter 5.8.2 of the ISO 20344-2004 standard,
- wherein the plurality of functional layers are adhered to each other to form the stratified and cohesive monolithic sheet-like structure.
A waterproof and vapor-permeable sole structure, comprising:
- a sole body including, in a lower region, a tread,
- wherein said sole body includes at least one opening that is adapted for vapor permeation and is covered, in a manner that is impermeable to water in the liquid state, by an insert for soles that has a stratified and cohesive monolithic sheet-like structure, comprising a plurality of waterproof and vapor permeable functional layers, each of the functional layers being made of a polymeric material that is permeable to water vapor and impermeable to water in the liquid state such that no water through passages are present in each of the functional layers and water in the liquid state is prevented from passing in each of the functional layers from a first side surface of a respective functional layer to a second side surface of the respective functional layer opposite the first side surface,
- at least one functional portion of said insert for soles having such a thickness as to give it a penetration resistance of more than approximately 10 N, evaluated according to the method presented in chapter 5.8.2 of the ISO 20344-2004 standard,
- wherein the plurality of functional layers are adhered to each other to form the stratified and cohesive monolithic sheet-like structure.
