Abstract

The present invention is directed to an article of footwear and method for making the same, where the article of footwear has a minimal number of upper pieces. The method of the present invention is directed to a process for manufacturing an article of footwear having a single or multiple layer upper. Each layer of the upper according to the present invention is constructed of a one-piece upper material. At least the outer layer of the upper is molded utilizing an embossing tool according to the present invention, such that the desired appearance of the upper is embossed on the outer layer. Additionally, the improved shoe manufacturing process of the present invention may further comprise the step of decorating at least the outer layer of the upper, by screen printing, sublimation, large format ink jet printing, cold and hot peel transfers, fabric dyeing and/or multi-layered digital printing, allowing for multiple or different colorways to be created using a single base color upper material. The tool and process according to the present invention exhibit great flexibility with respect to aesthetics, construction and cost values, allowing for the creation of an unlimited variety of upper appearances with minimal retooling time and costs.

Claims

1. An article of footwear comprising:

an upper formed from a one-piece outer layer and a one-piece inner layer joined to said outer layer; and

a sole disposed on said upper,

wherein said outer layer is molded with a desired texture and said inner layer comprises a bellows tongue arrangement.

2. An article of footwear according to claim 1, further comprising a one-piece middle layer adhered to said outer layer to form an outer layer/middle layer combination, wherein said one-piece inner layer is joined to said outer layer/middle layer combination.

3. An article of footwear according to claim 1, wherein said outer layer is molded by a process selected from the group consisting of at least one of the following:

thermal compression molding, RF welding, ultrasonic welding, thermal calendaring, and vacuum assisted forming;

such that the desired appearance of said upper is molded onto said outer layer.

4. An article of footwear according to claim 3, wherein said outer layer is molded with an embossing tool consisting of an embossing mold and at least one texture insert.

5. An article of footwear according to claim 1, wherein a portion of said inner layer is exposed on the vamp of the shoe.
