<p>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.</p> |
