Abstract

A last system and a method of making the last system are disclosed. The last system includes a last member and an exterior layer. The exterior layer becomes deformable when heated above a characteristic temperature. The method can include forming a braided footwear component on the last system. The exterior layer may be joined with the braided footwear component by heating the last system above the characteristic temperature.

First claim

The invention claimed is:

1. An upper for an article of footwear comprising: a composite material forming at least a portion of the upper, the composite material having a first surface and a second surface opposite the first surface and comprising:
a matrix material; and
a plurality of braided strands thermally bonded with the matrix material such that the plurality of braided strands are embedded within the matrix material, wherein an inner surface of the matrix material separates the plurality of braided strands and the first surface;
a first portion having a first thickness, the first thickness comprising the composite material; and
a second portion having a second thickness, the second thickness comprising the composite material, wherein the first thickness is greater than the second thickness.

2. The upper according to claim 1 , wherein the at least a portion of the plurality of braided strands are partially, but not fully, embedded with the matrix material.

3. The upper according to claim 1 , wherein the plurality of braided strands are completely encased within the matrix material.

4. The upper according to claim 1 , wherein the first portion is located in a toe region of the upper.

5. The upper according to claim 1 , wherein the first portion is located in a heel region of the upper.

6. The upper according to claim 1 , wherein the first portion is located in an eyestay region of the upper.

7. The upper according to claim 1 , wherein the first portion is located in a sole region of the upper.

8. The upper according to claim 1 , wherein the second portion is located in a medial side region of the upper.

9. An upper for an article of footwear comprising:
a composite material forming at least a portion of the upper, the composite material comprising:
a matrix comprising a heat deformable material; and
a plurality of braided strands thermally fused with the heat deformable material;
wherein the upper comprises an interior surface and an exterior surface opposite the interior surface, at least a portion of the interior surface comprising the matrix, and wherein a portion of the matrix separates the plurality of braided strands from the interior surface of the upper.

10. The upper according to claim 9 , wherein the composite material at the exterior surface of the upper comprises an outer surface of the matrix and at least a portion of the plurality of braided strands.

11. The upper according to claim 8 , wherein the plurality of braided strands are surrounded by the matrix at the interior surface and the exterior surface of the upper.
