First Claim
Patent Images
1. An article of footwear having an upper and a sole structure secured to the upper, at least a portion of the upper comprising:
- a pair of lace-receiving elements spaced from each other;
a material layer extending from the lace-receiving elements to the sole structure; and
a pair of strands extending from an area proximal to the lace-receiving elements to an area proximal to the sole structure, the strands lying substantially parallel to a surface of the material layer and secured to the material layer in a region between the lace-receiving elements and the sole structure, and the strands crossing each other in the region between the lace-receiving elements and the sole structure.

Abstract
An article of footwear may include various strands that extend from an area proximal to lace-receiving elements to an area proximal to a sole structure. The strands lie substantially parallel to a surface of a material layer in a region between the lace-receiving elements and the sole structure, and the strands cross each other in the region between the lace-receiving elements and the sole structure.

9. An article of footwear having an upper and a sole structure secured to the upper, at least a portion of the upper comprising:
-
a first lace-receiving element and a second lace-receiving element spaced from each other; a pair of material layers extending from the lace-receiving elements to the sole structure; a first group of strands located between and secured to at least one of the material layers, the first group of strands extending between an area proximal to the first lace-receiving element and the sole structure, the first group of strands lying substantially parallel to a surface of the material layers for a distance of at least five centimeters; and a second group of strands located between and secured to at least one of the material layers, the second group of strands extending between an area proximal to the second lace-receiving element and the sole structure, the second group of strands lying substantially parallel to the surface of the material layers for a distance of at least five centimeters, wherein at least two of the first group of strands crosses at least two of the second group of stands. - View Dependent Claims (10, 11, 12, 13, 14)

15. An article of footwear having an upper and a sole structure secured to the upper, at least a portion of the upper comprising:
-
a pair of material layers extending along at least one of a lateral side and a medial side of the upper and from an upper region of the upper to a lower region of the upper, the material layers defining a first lace aperture and a second lace aperture located in the upper region; a first strand located between the material layers and extending from an area proximal to the first lace aperture to the lower area of the upper, the first strand lying substantially parallel to a surface of the material layers and secured to at least one of the material layers for a distance of at least five centimeters in a region between the first lace aperture and the lower area of the upper; and a second strand located between the material layers and extending from an area proximal to the second lace aperture to the lower area of the upper, the second strand being secured to at least one of the material layers in a region between the second lace aperture and the lower area of the upper, and the second strand crossing the first strand. - View Dependent Claims (16, 17, 18, 19)
