Abstract

An article of footwear including a compression molded upper is disclosed. A composite structure including several layers is placed under heat and pressure to form a laminate. One layer of the composite is an optical effect layer possessing an aesthetic that differs from one or more of the other layers of the composite structure. A plurality of holes are cut through one or more of the layers of the laminate to expose the optical effect layer.

First claim

I claim:

1. A method of forming an upper for an article of footwear comprising:
compression molding multiple layers of fabric with heat and pressure that softens one or more of the multiple layers of fabric to cause the multiple layers of fabric to adhere together and form a fabric laminate defining a rearfoot portion or forefoot portion of the upper, the multiple layers of fabric including an interior textile layer, an intermediate foam layer, and an exterior textile layer;
cutting a plurality of holes through one or more layers of the multiple layers of fabric laminate with a cutting apparatus; and
laminating an optical effect layer of material to an innermost layer of the fabric laminate to provide an aesthetic effect that can be seen through the plurality of holes.

2. The method of claim 1 , wherein the compression molding forms perforations in the fabric laminate and the method further comprises aligning the fabric laminate within the cutting apparatus by aligning the perforations with blades of the cutting apparatus.

3. The method of claim 2 , wherein the perforations extend into the exterior textile layer and the plurality of holes extend through the interior textile layer, the intermediate foam layer and the exterior textile layer.

4. The method of claim 1 , wherein the optical effect layer of material is an aesthetic layer and the plurality of holes expose the aesthetic layer.

5. The method of claim 4 , further comprising removing material from the plurality of holes subsequent to the cutting.

6. A method of forming an upper for an article of footwear comprising:
compression molding multiple layers of fabric with heat and pressure that softens one or more of the multiple layers of fabric to cause the multiple layers of fabric to adhere together and form a fabric laminate defining a rearfoot portion or forefoot portion of the upper, wherein the compression molding forms a plurality of holes in the fabric laminate; and
laminating an optical effect layer of material to an innermost layer of the fabric laminate to provide an aesthetic effect that can be seen through the plurality of holes.

7. The method of claim 6 , further comprising:
removing loose material from the plurality of holes subsequent to the compression molding to expose the aesthetic effect.

8. The method of claim 6 , wherein the multiple layers of fabric comprise:
an interior layer, an intermediate layer, and an exterior layer, wherein perforations extend into the exterior layer and the holes extend through the interior layer, the intermediate layer and the exterior layer.

9. A method of forming an upper for an article of footwear comprising:
compression molding multiple layers of fabric with heat and pressure that softens one or more of the multiple layers of fabric to cause the multiple layers of fabric to adhere together and form a fabric laminate defining a rearfoot portion or forefoot portion of the upper, wherein the compression molding forms perforations in the fabric laminate;
aligning the fabric laminate within a cutting apparatus by aligning the perforations with blades included in the cutting apparatus; and
cutting a plurality of holes through one or more of the multiple layers of fabric laminate with the cutting apparatus to create an aesthetic effect.

10. The method of claim 9 , further comprising laminating an optical effect layer of material to an innermost layer of the fabric laminate to provide the aesthetic effect, which can be seen through the plurality of holes.

11. The method of claim 6 , wherein the optical effect layer of material comprises at least one of: a layer that has a higher degree of brightness than other layers of the multiple layers of fabric, a metal foil layer; a holographic layer, a reflective layer, or a transparent layer.

12. The method of claim 9 , wherein the aesthetic effect is created by exposing an optical effect layer of material that comprises at least one of: a layer that has a higher degree of brightness than other layers of the multiple layers of fabric, a metal foil layer; a holographic layer, a reflective layer, or a transparent layer.

13. The method of claim 9 , wherein the multiple layers of fabric comprise an interior textile layer, an intermediate foam layer, an exterior textile layer, and an optical effect layer of material, wherein the perforations extend into the exterior textile layer and the plurality of holes extend through at least the exterior textile layer to reveal the optical effect layer of material and create the aesthetic effect.
