First Claim
Patent Images
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; and
a tensile element including a base layer and a plurality of strands, the base layer being secured to the exterior surface, the base layer being located between the strands and the exterior surface, and the base layer defining a plurality of edges that expose at least one area of the exterior surface, the strands being positioned in contact with the base layer and substantially parallel to the base layer for a distance of at least five centimeters.

Abstract
An article of footwear may have a sole structure and an upper that includes a foundation element and a tensile element. The tensile element may include a base layer and a plurality of strands, with the base layer being joined to an exterior surface of the foundation element. In manufacturing the footwear, a thermoplastic polymer material in the base layer may be utilized to bond or otherwise join the tensile element to the foundation element.

11. 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; and a tensile element secured to the exterior surface, the tensile element including; (a) a base layer defining a plurality of base layer edges, (b) a cover layer that is coextensive with the base layer, the cover layer defining a plurality of cover layer edges located at the base layer edges, and (c) a plurality of strands positioned between the base layer and the cover layer, the strands being substantially parallel to the base layer for a distance of at least five centimeters, and ends of at least a portion of the strands being located at the edges of the base layer and the cover layer, wherein areas of the exterior surface extend beyond the tensile element and form portions of an exposed surface of the upper. - View Dependent Claims (12, 13, 14, 15)

16. 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; and a tensile element having; (a) a base layer including a thermoplastic polymer material secured to the exterior surface, the base layer defining an edge, (b) a cover layer joined to the base layer with the thermoplastic polymer material, the cover layer defining an edge positioned at the edge of the base layer, and (c) a plurality of strands positioned between the base layer and the cover layer, the strands being substantially parallel to the base layer for a distance of at least five centimeters, and ends of at least a portion of the strands being located at the edges of the base layer and the cover layer, wherein an area of the tensile element is less than an area of the exterior surface of the foundation element, and portions of the exterior surface of the foundation element form an exposed surface of the upper. - View Dependent Claims (17, 18, 19)
