  • Patent number: 6769201
    Abstract: Waterproof shoe structure with an exterior upper (1), an interior upper containing at least a waterproof, water vapor permeable functional layer (2) and a lining (3), an insole (4), and an outsole (8). The lower end of the exterior upper (1) and the insole (4) are joined by a seam (5), wherein the functional layer (2) at the lower end of the interior upper extends past the lining (3) and possibly additional layers of the interior upper by a lower portion of the functional layer. The extending portion of the functional layer (2) is joined to the lower end of the exterior upper (1) in a waterproof manner, and that the seam (5) joining the lower end of the exterior upper (1) to the insole (4) is located exclusively in the portion (a) of the lower end of the exterior and interior uppers in which the lower portion of the functional layer is joined to the exterior upper (1) in a waterproof manner.

  • Patent number: 6698108
    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.
