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, the foundation element including a plurality of lace apertures in a lace area of the upper; a plurality of tensile strands located adjacent to the exterior surface and extending between the lace area of the upper and an area where the sole structure is joined to the upper; the plurality of tensile strands comprising a plurality of strand groups each including two or more of the tensile strands, each of the plurality of strand groups having said two or more of the tensile strands oriented to radiate outward from one of the plurality of lace apertures in the lace area of the upper towards the area where the sole structure joins to the upper; and a plurality of securing strands that secures the plurality of tensile strands to the foundation element.
