Abstract

A tensile strand element for an article of footwear is disclosed. The tensile strand element includes one or more tensile strands secured at their endpoints between the sole and upper of an article of footwear, creating one or more looped portions. The unsecured looped portions may extend into the fastening region of the footwear and engage with a fastening system to tighten the footwear upper snugly against a wearer'"'"'s foot to provide added support.

Claims

1. An article of footwear comprising:

an upper having a fastening region that includes a fastening system;

a cover layer over the upper that forms a portion of an exterior surface of the footwear, the cover having an upper end and a lower end, the upper and the cover layer forming an unattached region where the upper and the cover layer are unsecured to each other, the cover layer defining a first aperture and a second aperture in the unattached region, the first and second apertures being between the upper end and the lower end of the cover layer;

a sole attached to the upper and spaced from the fastening region; and

a first tensile strand element having a tensile strand with a first attachment point, a second attachment point, and an unsecured portion located between the first attachment point and the second attachment point, the first attachment point and the second attachment point being adjacent to the sole, a first section of the unsecured portion being located between the upper and the cover layer in the unattached region, and a second section of the unsecured portion including a first looped portion that extends through the first aperture in the cover layer and is located adjacent to the exterior surface of the footwear, the first looped portion being configured to receive an element of the fastening system,

a second tensile strand element, the second tensile strand element comprising a second looped portion that extends through the second aperture in the cover layer,

wherein at least a portion of the first tensile strand element and at least a portion of the second tensile strand element is positioned between the upper and the cover layer.

2. The article of footwear according to claim 1, wherein the first tensile strand element is secured between the sole and the upper at the first attachment point and at the second attachment point.

3. The article of footwear according to claim 2, the article of footwear having a longitudinal direction directed from a toe end of the article of footwear to a heel end of the article of footwear, and wherein the first attachment point and the second attachment point are at the same location along the longitudinal direction.

4. The article of footwear according to claim 2, wherein the first attachment point is closer to a toe end of the article of footwear and the second attachment point is closer to a heel end of the article of footwear.

5. The article of footwear according to claim 1, wherein the fastening system comprises laces.

6. The article of footwear according to claim 1, wherein the first tensile strand element comprises a plurality of tensile strands.

7. The article of footwear according to claim 6, wherein the plurality of tensile strands comprise a plurality of first looped portions, the first looped portions being co-located to receive an element of the fastening system, and wherein a distance between adjacent ones of the plurality of tensile strands is greatest at the plurality of attachment points on the sole.

8. The article of footwear according to claim 6, wherein the first tensile strand element comprises 6 tensile strands.

9. The article of footwear according to claim 8, wherein the 6 tensile strands are formed from one tensile strand that is secured at 12 locations to create 6 unsecured portions.

10. The article of footwear according to claim 6, wherein the first tensile strand element comprises 2 tensile strands.

11. The article of footwear according to claim 1, wherein the first tensile strand element is positioned on a lateral side of the upper.

12. The article of footwear according to claim 1, wherein the first tensile strand element is positioned on a medial side of the upper.

13. The article of footwear according to claim 1, wherein the unsecured portion of the first tensile strand comprises:

a first portion located between the first attachment point and the first looped portion;

a second portion located between the second attachment point and the first looped portion; and

wherein the first portion and the second portion are twisted between the first attachment point, the second attachment point, and the first looped portion.

14. The article of footwear according to claim 1, wherein the cover layer comprises a warp-knitted material.

15. An article of footwear comprising:

an upper having a fastening region that includes a lace;

a cover layer over the upper that forms a portion of an exterior surface of the footwear, the cover having an upper end and a lower end, the upper and the cover layer forming an unattached region where the upper and the cover layer are unsecured to each other, the cover layer comprising a first aperture and a second aperture that are located between the upper end and the lower end;

a sole attached to the upper and spaced from the fastening region;

a first tensile strand element, the tensile strand element being located between the upper and the cover layer and including a plurality of tensile strands, each of the plurality of tensile strands having two attachment points and an unsecured portion located between the two attachment points, each unsecured portion having a first looped portion, wherein each first looped portion is co-located and is extends through the first aperture in the cover layer to receive the lace, and

a second tensile strand element, the second tensile strand element comprising a second looped portion that extends through the second aperture in the cover layer to receive the lace.

16. The article of footwear according to claim 15, wherein each of the two attachment points is secured proximate the sole.

17. The article of footwear according to claim 15, further comprising a third tensile strand element and a fourth tensile strand element.
