Abstract
Waterproof, water vapor permeable shoe construction including an exterior upper, a waterproof, water vapor permeable functional-layer upper, a lining upper, and a sole. Both the waterproof, water vapor permeable functional-layer upper and the lining upper are in the shape of a sock and introduced separately into the shoe. The functional-layer upper and lining upper are preferably joined to the exterior upper only at a top opening of the shoe construction through which a foot is inserted. The functional-layer upper can be composed of individual pieces that are joined together by seams that are sealed, or it can be seamless. The method for manufacturing the waterproof, water vapor permeable shoe has the steps of manufacturing a exterior upper; manufacturing a waterproof, water vapor permeable functional-layer upper in the shape of a sock; manufacturing a lining upper in the shape of a sock; inserting the functional-layer upper into the exterior upper; inserting the lining upper into the functional-layer upper; and applying a sole from underneath.
