An insert for soles, particularly for perforated soles made of polymeric material, comprising a membrane (13) that is impermeable to water and permeable to water vapor, the insert (10) comprising a supporting layer (11) made of mesh, felt or other diffusely perforated material, a vapor permeation component (12), which comprises the membrane (13) arranged above the supporting layer (11), a layer of polymeric material (14) that impregnates locally the supporting layer (11), so as to form therein a matrix (15) for the adhesive bonding thereof to other components of the shoe, a region (16) for sealing the supporting layer (11) to the vapor permeation component (12). The adhesive bonding matrix (15) affects at least the perimetric region of the supporting layer (11) and delimits at least one vapor-permeable portion (18) of the supporting layer (11), which is free from polymeric material (14). The sealing region (16) provides for the intimate grip of the polymeric material (14), which impregnates the supporting layer (11), to the membrane (13). |
