Abstract

The invention relates to footwear comprising a shank and a sole construction having an outsole. The shank is constructed with an upper material and with a water-tight functional layer which at least partially lines the upper material on the inner side thereof. In addition, the shank comprises a shank end area which is situated on the side of the sole and which has an upper material end area and a functional layer end area. The functional layer end area comprises an area which requires sealing, and the outsole is glued to the shank end area by means of an outsole adhesive situated on said outsole. The outsole adhesive is formed by a reactive hot-melt adhesive at least in one outsole partial area located opposite the area of the functional end area which requires sealing. Said hot-melt adhesive leads to water impermeability when complete reacted.

Claims

1. Footwear comprising an upper and a sole construction having an outsole, the upper being constructed with an outer material having an inner side and an outer side and with a waterproof functional layer at least partially lining the outer material on the inner side and having an upper end region with an outer-material end region and a functional-layer end region;

the functional-layer end region having a region requiring sealing; and

the outsole being adhesively bonded to the upper end region by means of outsole cement located on the outsole, the outsole cement being formed, at least in a sub-region of the outsole lying opposite the region of the functional-layer end region requiring sealing, by a reactive hot-melt adhesive which is in direct contact with the functional-layer end region and which brings about waterproofness when in the fully reacted state, and wherein the sole construction comprises an insole and a gauze strip is arranged between the insole and the outer-material end region, the gauze strip being joined to the insole and to the outer-material end region as well as to the functional-layer end region.

2. Footwear according to claim 1, wherein the outsole cement is formed by a reactive hot-melt adhesive at least in a sub-region of the outsole, which is closed off in the direction of the sole periphery and lies opposite the gauze strip.

3. Footwear according to claim 2, wherein the outsole cement is formed by an expanded reactive hot-melt adhesive at least in a sub-region of the outsole, which is closed in the direction of the sole periphery and lies opposite the gauze strip.

4. Footwear according to claim 2, wherein the entire outsole surface is provided with the reactive hot-melt adhesive.

5. Footwear according to claim 3, wherein the entire outsole surface is provided with the expanded reactive hot-melt adhesive.

6. Footwear according to claim 1, wherein filler is arranged between the insole and the outsole.

7. Footwear according to claim 1, wherein a first side edge of the gauze strip is joined to the outer-material end region and a second side edge is joined both to the insole and to the functional-layer end region.

8. Footwear according to claim 1, wherein a first side edge of the gauze strip is joined both to the outer-material end region and to the functional-layer end region and a second side edge is joined to the insole.

9. Footwear according to claim 1, wherein the outer-material end region and the functional-layer end region are fastened to each other by means of a fixing adhesive.
