The inner shaft includes at least one waterproof, water-vapor permeable functional layer and at least one layer of lining material which faces the inside of the shoe structure. An extension, made of a waterproof material, is connected in a waterproof manner to a lower end of the inner shaft which faces an outsole of the shoe. The inner shaft is fixed in place in the sole area by the extension only. The extension preferably encloses the lower end of the inner shaft.
