Sole structure able to associated to an upper of a shoe, having first ducts in the area of the plantar arch and of the tip and one or more lateral openings in the heel area. In the heel area is obtained a seat for a counter-shaped insert provided with at least an elastically compressible central area, inferiorly communicating with second ducts communicating in turn with third ducts obtained superiorly to the insert and communicating with the first ducts and with the openings, and through the interposition of a gasket permeable to air but not to water. The insert has an upper surface whereon is obtained a central area, elastically compressible and inferiorly communicating with a cavity, obtained on a lower surface of the insert, in such a way that to a deformation of the central area corresponds a variation of the volume of the cavity.
