ABSTRACT:
A waterproof foot covering such as a shoe, boot or the like has a molded-on (foamed-on) outersole and an upper that is lined with a waterproof but water vapor-permeable layer. The lower welt region of the upper is connected to the lower welt region of the waterproof layer and to the outer welt region of the inner sole via an upper band, a lower band, and a multiplicity of tensile-load-resistant straps connecting the upper and lower bands to one another. The lower welt region of the upper is stitched to the upper band. The lower welt region of the waterproof layer and the outer welt region of the inner sole are stitched to the lower band. The straps and the lower band are embedded in the material forming the outersole. This material is connected, in this embedding region, to the waterproof layer in a waterproof manner by molding-on (foaming-on).
