Abstract

Articles of footwear may include an upper with a forward lace-receiving element and a plurality of strands that extend forward from the lace-receiving element. In some configurations, the strands are located between a pair of material layers and lay substantially parallel to the material layers. In other configurations, the material layers form a loop structure, and the strands may extend at least partially around the loop structure.

Claims

1. An article of footwear having an upper and a sole structure secured to the upper, the upper comprising:

a throat area extending forward from an ankle opening of the upper towards a forefoot region, the throat area including a plurality of lace-receiving elements that include a forward lace-receiving element positioned closer to a forward edge of the article of footwear than other lace-receiving elements, the forward lace-receiving element being centrally positioned and extending between a medial side and a lateral side of the throat area;

a lace extending through at least the forward lace-receiving element;

a tensile strand element located within the forefoot region of the article of footwear, the tensile strand element including (i) at least one material layer, and (ii) a plurality of strands that lay adjacent to a surface of the material layer, the tensile strand element forming a loop that defines the forward lace-receiving element, the plurality of strands extending at least partially around the loop; and

wherein the plurality of strands extend from an area proximal to the forward lace-receiving element on a top portion of the upper located forward of the throat area towards the forward edge of the article of footwear.

2. The article of footwear according to claim 1, wherein the plurality of strands extend to the forward edge.

3. The article of footwear according to claim 1, wherein the plurality of strands terminate inward of the forward edge.

4. The article of footwear according to claim 1, wherein the plurality of strands cross each other between the area proximal to the forward lace-receiving element and the forward edge.

5. The article of footwear according to claim 1, wherein the plurality of strands exhibit a branching structure on the top portion of the upper located forward of the throat area.

6. The article of footwear according to claim 1, wherein at least a portion of the plurality of strands exhibit a wavy or non-linear configuration on the top portion of the upper located forward of the throat area.

7. The article of footwear according to claim 1, wherein the plurality of strands further extend through portions of at least a midfoot region and a heel region of the article of footwear.

8. The article of footwear according to claim 1, wherein the plurality of strands are exposed on the tensile strand element.

9. The article of footwear according to claim 1, wherein the at least one material layer of the tensile strand element comprises a base layer and a cover layer;

and

wherein the plurality of strands are located between the base layer and the cover layer in the tensile strand element.

10. The article of footwear according to claim 9, wherein the base layer is substantially planar and the cover layer protrudes outward in the location of the plurality of strands.

11. The article of footwear according to claim 9, wherein the base layer and the cover layer protrude outward in the location of the plurality of strands.

12. The article of footwear according to claim 9, further comprising an additional layer located adjacent to the base layer.

13. The article of footwear according to claim 9, wherein the plurality of strands are disposed along a first side of the base layer;

and

wherein an additional set of strands is located along a second side of the base layer opposite the first side.

14. The article of footwear according to claim 13, wherein an additional layer is located adjacent to the second side of the base layer, the additional layer covering the additional set of strands.

15. An article of footwear having an upper and a sole structure secured to the upper, the upper comprising:

a throat area extending forward from an ankle opening of the upper towards a forefoot region, the throat area including a plurality of lateral lace-receiving elements extending along a lateral side of the upper, a plurality of medial lace-receiving elements extending along a medial side of the upper, and a forward lace-receiving element centrally positioned and extending between the lateral side and the medial side at a forward portion of the throat area adjacent to the forefoot region;

a lace extending through the lateral lace-receiving elements, the medial lace-receiving elements, and the forward lace-receiving element;

a tensile strand element located within the forefoot region of the footwear, the tensile strand element including a first layer, a second layer, and a plurality of strands located between the first layer and the second layer;

wherein at least the first layer, the second layer, and the plurality of strands form the forward lace-receiving element being centrally positioned on a top portion of the upper located forward of the throat area;

wherein the first layer, the second layer, and the plurality of strands extend forward from an area proximal to the forward lace-receiving element on the top portion of the upper towards a forward edge of the article of footwear; and

wherein the forward lace-receiving element is a loop formed by the first layer, the second layer, and the plurality of strands extending at least partially around the loop.
