Abstract
Described are shoe uppers in which at least a portion thereof is formed of a multilayered material. The multilayered material includes at least one nonwoven fiber layer with unidirectionally oriented fibers and a matrix material, wherein the multilayered material has elastic properties that allow the multilayered material to deform when stretched over a three dimensional mold.
Claims34
A shoe upper comprising at least a portion formed of a multilayered material comprising:
- (a) a collection of an odd number of nonwoven fiber layers, wherein the collection comprises a base layer and at least one set of paired layers, each nonwoven fiber layer comprising a plurality of unidirectionally oriented fibers, wherein the fibers in a first layer of the at least one set of paired layers form an angle in the range of −25° to 65° with respect to the fibers in the base layer, and the fibers in a second layer of the at least one set of paired layers form an angle in the range of +25° to +65° with respect to the fibers in the base layer;
- and
- (b) a matrix material;
- wherein the multilayered material comprises elastic properties that allow the multilayered material to deform into a smooth three dimensional shape when the multilayered material is stretched over a three dimensional mold, wherein the multilayered material is not cut or sewn to eliminate wrinkles in the smooth three dimensional shape.

A shoe upper comprising:
- (a) a first portion formed of a breathable material;
- (b) a second portion formed of a multilayered material comprising:
- (i) a collection of an odd number of nonwoven fiber layers, wherein the collection comprises a base layer and at least one set of paired layers, each nonwoven fiber layer comprising a plurality of unidirectionally oriented fibers, wherein the fibers in a first layer of the at least one set of paired layers form an angle in the range of −25° to 65° with respect to the fibers in the base layer, and the fibers in a second layer of the at least one set of paired layers form an angle in the range of +25° to +65° with respect to the fibers in the base layer;
- and
- (ii) a matrix material;
- wherein the multilayered material comprises elastic properties that allow the multilayered material to deform into a smooth three dimensional shape when the multilayered material is stretched over a three dimensional mold, wherein the multilayered material is not cut or sewn to eliminate wrinkles in the smooth three dimensional shape.
