Article of footwear incorporating tensile strands and securing strands
First Claim
1. An article of footwear having an upper and a sole structure secured to the upper, the upper comprising:
- a foundation element having an interior surface and an opposite exterior surface, the interior surface defining at least a portion of a void within the upper for receiving a foot of a wearer;
a first strand located adjacent to the exterior surface and substantially parallel to the exterior surface for a distance of at least five centimeters, the first strand having a first thickness; and
a second strand securing the first strand to the foundation element, the second strand having a second thickness, the first thickness being at least three times the second thickness,the first strand stretching to a lesser degree than the foundation element to resist stretch in the upper.

Abstract
An article of footwear may have a sole structure and an upper that includes a foundation element, a tensile strand, and a securing strand. The tensile strand is located adjacent to an exterior surface of the foundation element and substantially parallel to the exterior surface for a distance of at least five centimeters. The securing strand joins or secures the tensile strand to the foundation element. Although the thicknesses may vary, a thickness of the tensile strand may be at least three times the thickness of the securing strand. In some configurations, a backing strand may also assist with joining the securing strand to the foundation element.
