Embodiment Construction

[0034] The following description and accompanying drawings disclose various uppers for articles of footwear, the uppers (or at least some portions thereof) being formed at least in part from materials manufactured by a jersey knitting process. The upper is integrated with a shoe suitable for sports including running and yoga. The concepts related to shoes and uppers are not limited to shoes designed for running and yoga, but they can be applied to a wider range of sports shoes including, for example, baseball shoes, basketball shoes, cross-training, bicycles Shoes, rugby shoes, tennis shoes, soccer shoes, walking shoes and hiking boots. The concept may also refer to categories of footwear generally considered to be non-athletic, including dress shoes, slippers, loafers, and work boots. The concepts disclosed herein are thus applicable to various shoe types. Also, the concepts of the present invention can be used in conjunction with other parts of the shoe structure, such as ...

Abstract

An article of footwear may include an upper with a knitted element formed through a flat knitting process. In one configuration, the knitted element has an area with a first layer and a second layer at least partially coextensive with the first layer. The first layer is formed of unitary construction with the second layer, and the second layer is joined to the first layer at opposite sides of the second layer. In another configuration, a knitted element for footwear includes a foot-receiving portion and one or more straps formed of unitary construction with the foot-receiving portion. The foot-receiving portion defines a void for receiving the foot, and the strap(s) extend outward from sides of the foot-receiving portion.

Description

Background technique [0001] A traditional article of athletic footwear includes two main elements, the upper structure and the sole structure. The upper provides coverage of the foot, the upper structure securely receiving and positioning the foot relative to the sole structure. Additionally, the upper may have a construction that protects the foot and provides breathability, thereby cooling the foot and removing moisture. The sole structure is secured to the lower surface of the upper and is generally positioned between the foot and the ground. In addition to cushioning ground reaction forces, the sole structure provides traction and controls foot movements such as pronation. Thus, the upper structure and the sole structure cooperate to provide a comfortable structure suitable for various physical activities such as walking and running. The general features and construction of conventional shoe uppers are described in detail below. [0002] The upper forms a cavity inside...
