Shoe with composite upper and method of making the same
First Claim
1. An upper for an article of footwear, comprising:
- a base layer;
a first skin layer partially covering the base layer, wherein the first skin layer includes;
(1) a thermoset polyurethane material or a thermoplastic polyurethane material and (2) a hot melt material; and
a second skin layer partially covering the base layer, wherein the second skin layer includes;
(1) a thermoset polyurethane material or a thermoplastic polyurethane material and (2) a hot melt material,wherein;
(a) at a first portion of the upper, the first skin layer;
(1) directly contacts and is fuse bonded to the base layer by the hot melt material of the first skin layer and (2) is covered by and fuse bonded to the second skin layer by the hot melt material of the second skin layer, and(b) at a second portion of the upper, the second skin layer;
(1) directly contacts and is fuse bonded to the base layer by the hot melt material of the second skin layer and (2) is covered by and fuse bonded to the first skin layer by the hot melt material of the first skin layer.

Abstract
Uppers for article of footwear may include one or more skin layers attached to a base layer, wherein the skin layers overlap with one another in varying ways (e.g., with a first skin layer overlaying a second skin layer at some locations and the second skin layer overlaying the first skin layer at other locations). If desired, at least one of the skin layers may be at least partially transparent or translucent. The skin layer(s) may be applied over other elements of the upper (e.g., other skin layers, base layers, reinforcing layers, etc.). Additional aspects of this invention relate to production of curved tongue composite structures and/or footwear having a bonded (hot melt) side seam for forming the upper (and optionally do not include a rear heel seam).
