Embodiment Construction

[0104]The present disclosure relates to an upper for footwear and methods for making the footwear upper. The invention involves application of a knitting process to the production of footwear uppers. In one preferred embodiment, a knitting process is disclosed to create a completely seamless upper portion of a shoe. The process can form the footwear upper in a single step. Some benefits of this process include ease and efficiency of production, reduction of assembly time, maximum comfort through reduction of seams, and freedom of design. The methods can include weaving and / or knitting the upper. The knitting process typically includes forming upper by interconnecting a series of stitches or loops.

[0105]In the following description, and for the purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the various aspects of the invention. It will be understood, however, by those skilled in the relevant arts, that the present inve...

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application claims the benefit of U.S. Provisional Patent Application No. 61 / 473,473, entitled “SEAMLESS UPPER FOR FOOTWEAR AND METHOD FOR MAKING THE SAME” filed on Apr. 8, 2011, the entire disclosure of which is incorporated by reference herein.FIELD OF INVENTION[0002]This invention relates generally to an upper for footwear, more particularly to a seamless upper for footwear and method for making the same.BACKGROUND OF THE INVENTION[0003]The upper portion of footwear vary in composition and design based on several design parameters, to include function / performance, weight, cost, aesthetics, comfort and ease of manufacture. Athletic shoes, for example, typically emphasize performance as dictated by the sport. A running shoe is commonly of lighter-weight than a tennis shoe, for example, given a running shoe generally does not require the lateral support of a tennis shoe. Given the particular cost-competitive nature of footwear and th...
