Insert for soles, particularly for perforated soles made of polymeric material, and sole comprising said insert

摘要

An insert for soles, particularly for perforated soles made of polymeric material, comprising a membrane that is impermeable to water and permeable to water vapor, the insert comprising a supporting layer made of mesh, felt or other diffusely perforated material, a vapor permeation component, which comprises the membrane arranged above the supporting layer, a layer of polymeric material that impregnates locally the supporting layer, so as to form therein a matrix for the adhesive bonding thereof to other components of the shoe, a region for sealing the supporting layer to the vapor permeation component. The adhesive bonding matrix affects at least the perimetric region of the supporting layer and delimits at least one vapor-permeable portion of the supporting layer, which is free from polymeric material. The sealing region provides for the intimate grip of the polymeric material, which impregnates the supporting layer, to the membrane.

1. An insert for soles, particularly for perforated soles made of polymeric material, comprising a membrane that is impermeable to water and permeable to water vapor, the insert comprising:
a supporting layer made of mesh, felt or other diffusely perforated material; a vapor permeation component, which comprises a membrane that is impermeable to water and permeable to water vapor and is arranged above said supporting layer; and a layer of polymeric material that impregnates locally said supporting layer, forming therein an adhesive bonding matrix for adhesive bonding thereof to a bearing frame of the sole, said adhesive bonding matrix affecting at least a perimetric region of said supporting layer and delimiting at least one vapor-permeable portion of said supporting layer that is free from said polymeric material for its permeability to water vapor, wherein the bearing frame includes, on its face that lies opposite a face connected to the insert, a tread surface and a structural grid, the structural grid having studs that protrude therefrom that are adapted for contact with a ground surface.
