Abstract:
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.
