Article Of Footwear Incorporating Tensile Strands And Securing Strands

摘要

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.

主权项

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 joined to the foundation element at a plurality of locations on opposite sides of the first strand and along the distance of at least five centimeters to secure the first strand to the foundation element, the first strand being positioned between the foundation element and the second strand; and wherein the first strand extends substantially along at least a portion of a longitudinal length of the upper in a direction between a forefoot region and a heel region of the article of footwear.
