Patent ID: 8312644

Claim:
A water-vapor-permeable composite shoe sole designed for footwear, with at least one through hole extending through the thickness of the composite shoe sole, which is closed by a shoe-reinforcement material that has a fiber composite with a first fiber component and a second fiber component, having two fiber parts, whereby the first fiber component has a first melting point and a first softening-temperature range lying below the first melting point and a second fiber part of the second fiber component has a second melting point and a second softening-temperature range lying below the second melting point; the first melting point and the first softening-temperature range are higher than the second melting point and the second softening-temperature range; the first fiber part of the second fiber component has a higher melting point and a higher softening temperature range lying beneath the first fiber part's melting point than the second fiber part; and the fiber composite is thermally bonded, while retaining water-vapor permeability in the thermally bonded area, as a result of thermal activation of the second fiber part of the second fiber component with an adhesive softening temperature lying in the second softening-temperature range wherein a shaft is provided on a shaft-end area on a sole side with a waterproof and water-vapor-permeable shaft-bottom functional layer, whereby the composite shoe sole is connected to the shaft-end area provided with the shaft-bottom functional layer, so that the shaft-bottom functional layer is not connected to the shoe-reinforcement material, at least in the area of the at least one through hole.
