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;

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

a fastening system; and

a 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, wherein;

the unsecured portion includes an innermost portion and an outermost portion positioned over the innermost portion, the innermost portion being closer to the upper than the outermost portion;

the first attachment point and the second attachment point are adjacent to the sole; and

the unsecured portion includes a looped portion configured to receive an element of the fastening system.

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

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

5. The article of footwear according to claim 4, wherein the tensile strand element comprises 6 tensile strands.

6. The article of footwear according to claim 5, wherein the 6 tensile strands are formed from one tensile strand that is secured at 12 attachment points to create 6 unsecured portions.

7. The article of footwear according to claim 1, further comprising a cover layer positioned over the upper and the tensile strand element.

8. The article of footwear according to claim 7, wherein the cover layer comprises an aperture, and wherein the looped portion of the tensile strand element protrudes through the aperture towards the exterior surface of the upper.

9. The article of footwear according to claim 4, wherein:

each of the plurality of tensile strands includes two attachment points forming a plurality of attachment points and an unsecured portion located between the two attachment points forming a plurality of looped portions;

the plurality of looped portions are co-located and configured to receive an element of the fastening system together; and

each of the plurality of tensile strands extends from the plurality of looped portions to the plurality of attachment points, the plurality of attachment points being spaced apart and adjacent to the sole, the plurality of tensile strands together deflecting in a tent-like shape from the fastening region to the sole.

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

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

12. An article of footwear comprising:

an upper having a fastening region that includes a lace;

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

a tensile strand element 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 looped portion, wherein each looped portion is co-located and is configured to receive an element of the fastening system.

13. The article of footwear according to claim 12, wherein each of the plurality of tensile strands is secured between the sole and the upper at the respective two attachment points.

14. The article of footwear according to claim 12, further comprising a plurality of tensile strand elements.

15. The article of footwear according to claim 12, wherein the tensile strand element comprises 6 tensile strands.

16. The article of footwear according to claim 15, wherein the 6 tensile strands are formed from one tensile strand that is secured at 12 attachment points to create 6 unsecured portions.

17. The article of footwear according to claim 12, wherein:

for each of the plurality of tensile strands, the plurality of looped portions are co-located and configured to receive an element of the fastening system together; and

the plurality of tensile strands extend from the plurality of looped portions to the respective two attachment points, the respective two attachment points for each tensile strand being spaced apart and adjacent to the sole, the plurality of tensile strands together deflecting in a tent-like shape from the looped portions to the two attachment points.

18. The article of footwear according to claim 12, further comprising a cover layer positioned over the upper and the tensile strand element.

19. The article of footwear according to claim 18, wherein the cover layer comprises an aperture, and wherein the looped portions of the tensile strand element protrude through the aperture towards an outer surface of the article of footwear.

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

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

22. The article of footwear according to claim 12, wherein the plurality of tensile strands comprises:

a first tensile strand with a first attachment point, a second attachment point, and a first unsecured portion located between the first attachment point and the second attachment point, the first unsecured portion including a first looped portion,

a second tensile strand with a third attachment point, a fourth attachment point, and a second unsecured portion located between the third attachment point and the fourth attachment point, the second unsecured portion including a second looped portion, and

wherein the first attachment point and the second attachment point are located proximate the sole, and wherein the first attachment point is closer to a heel end of the article of footwear and the second attachment point is closer to a toe end of the article of footwear; and

wherein the third attachment point and the fourth attachment point are located proximate the sole between the first attachment point and the second attachment point, and wherein the third attachment point is closer to a heel end of the article of footwear and the fourth attachment point is closer to a toe end of the article of footwear.

23. The article of footwear according to claim 12, wherein the second tensile strand includes a first portion located between the third attachment point and the second looped portion and a second portion located between the fourth attachment point and the second looped portion, and wherein the first portion crosses the second portion.

24. The article of footwear according to claim 12, wherein an axis running through the first looped portion and the second looped portion is parallel to the upper.
