Abstract: A sock-like shoe insert is provided which incorporates an upper of waterproof, water-vapor permeable functional layer for waterproof, breathable footwear and a sole of a waterproof, non-porous plastic film that can be stretched in two directions.

Abstract: Waterproof, breathable footwear with an upper connected to an insole, the upper having an outside layer formed of an outer upper material and an inside layer constructed of a waterproof, water vapor-permeable functional layer and a liner material in which on the bottom end of the upper, the inside layer extends about 5 mm beyond the outside layer. Only the bottom end of inside layer is sewn to insole. The bottom end of outside layer is glued to the inside layer by an adhesive. An outsole is injection molded onto the insole, and the bottom ends of inside and outside layers.

Abstract: Wearing apparel with an air-impermeable or only slightly air-permeable layer which is lined with ventilation material which has longitudinal air duct and transverse air ducts.

Abstract: Footwear consisting of an insole, an upper sewn to the insole, a lining for lining the upper which is also sewn to the insole and has microporous functional layer that is waterproof and permeable to water vapor, and a waterproof plastic sole which is injection-molded to the bottom side of the insole and the lower portion of the upper and encloses the seam region. The lower portion of the upper which is adjacent to the insole is formed by a porous material that is adapted to be penetrated by the plastic sole material which is liquid during the injection molding operation.
