Footwear incorporating a textile with fusible filaments and fibers
First Claim
1. An article of footwear having a sole structure and an upper secured to the sole structure, the upper incorporating a textile comprising:
- a fused area having a plurality of first strands that are fused to adjacent first strands to define a fused portion of the upper; and
an unfused area having a plurality of second strands that are unfused to adjacent second strands to define an unfused portion of the upper, wherein the fused area is adjacent the unfused area, and each of the fused area and the unfused area are positioned in an interior portion of the textile and have a spaced relationship with edges of the textile.

Abstract
The invention is an upper for an article of footwear that includes a textile having fusible filaments or fibers. The textile is incorporated into the upper and specific areas of the upper are heated such that the fusible filaments or fibers fuse with other filaments or fibers to form fused areas. In comparison with unfused areas of the upper, the fused areas may impart properties that include greater stretch-resistance, stability, support, abrasion-resistance, durability, and stiffness, for example. In addition, the fused areas generally provide air-permeability without significantly increasing the weight of the footwear.

- 16. An article of footwear comprising a sole structure and an upper secured to the sole structure, the upper incorporating a textile with a yarn that extends through a fused area and an unfused area of the textile, the yarn being formed of at least one thermoplastic polymer material, the yarn being fused in the fused area, and the yarn being unfused in the unfused area, wherein each of the fused area and the unfused area are positioned in an interior portion of the textile and have a spaced relationship with edges of the textile.
- 19. An article of footwear comprising a sole structure and an upper secured to the sole structure, the upper incorporating a textile formed from mechanically manipulated yarns with a plurality of first strands and second strands that form a tubular structure, the textile having a fused area wherein the first strands are fused to adjacent first strands to define a fused portion of the upper, and the textile, having an unfused area wherein the second strands are unfused to adjacent second strands define an unfused portion of the upper, the fused area being adjacent the unfused area, and each of the fused area and the unfused area being positioned in an interior portion of the textile and have a spaced relationship with edges of the textile.
