Abstract

An article of footwear includes an upper with a heel region that extends posteriorly about the heel, a medial side, and a lateral side. The article of footwear also includes a sole structure. Moreover, the article includes a longitudinal strand that extends along at least one of the medial side and the lateral side. Also, the article includes an underfoot strand that is coupled to the longitudinal strand and that extends across the sole structure to extend between the lateral side and the medial side of the upper. Furthermore, the article includes a closure strand that is coupled to the longitudinal strand. The closure strand is configured to couple to the closure element such that tensioning of the closure element tensions the longitudinal strand, the underfoot strand, and the closure strand to selectively secure the article of footwear to the foot.

First claim

What is claimed is:

1. An article of footwear including a sole structure, the article of footwear comprising:
a forefoot region;
a heel region opposite the forefoot region;
a medial side extending from the forefoot region to the heel region;
a lateral side opposite the medial side and extending from the forefoot region to the heel region;
a closure element configured to secure the article of footwear to a foot;
a first longitudinal strand disposed on one of the medial side and the lateral side and extending between a first end located proximate to the forefoot region and a second end located proximate to the heel region;
a second longitudinal strand disposed on the other of the medial side and the lateral side and extending between a first end located proximate to the forefoot region and a second end located proximate to the heel region; and
an underfoot strand including a first segment extending through the sole structure from a first position coupled to the first longitudinal strand to a second position coupled to the second longitudinal strand, and a second segment extending from the second position coupled to the second longitudinal strand, through the sole structure, to a third position coupled to the first longitudinal strand.

2. The article of footwear of claim 1 , wherein the first end of the first longitudinal strand and the first end of the second longitudinal strand are coupled to a securement member and the second end of the first longitudinal strand and the second end of the second longitudinal strand are coupled to a heel strap.

3. The article of footwear of claim 1 , wherein tensioning the closure element urges the first end of the first longitudinal strand toward the second end of the first longitudinal strand.

4. The article of footwear of claim 3 , wherein tensioning the closure element urges the first end of the second longitudinal strand toward the second end of the second longitudinal strand.

5. The article of footwear of claim 1 , further comprising:
a first closure strand having a first end and a second end and extending continuously between the first end and the second end of the first closure strand and between the closure element and the first longitudinal strand, the first closure strand contacting the closure element at more than one location along a length of the first closure strand; and
a second closure strand having a first end and a second end and extending continuously between the first end and the second end of the second closure strand and between the closure element and the second longitudinal strand, the second closure strand contacting the closure element at more than one location along a length of the second closure strand.

6. The article of footwear of claim 5 , wherein tensioning of the closure element tensions the first longitudinal strand, the second longitudinal strand, and the underfoot strand.

7. The article of footwear of claim 5 , wherein the first end of the first closure strand is coupled to a first location of the article of footwear and the second end of the first closure strand is coupled to a second location of the article of footwear, the first location disposed between the forefoot region and the heel region and the second location disposed between the first location and the heel region.

8. The article of footwear of claim 7 , wherein the first end of the first longitudinal strand is coupled to the first location of the article of footwear and the second end of the first longitudinal strand is coupled to a third location of the article of footwear.

9. The article of footwear of claim 8 , wherein the second location is disposed between the first location and the third location in a direction extending between the forefoot region and the heel region.

10. The article of footwear of claim 8 , wherein the first location and the second location are disposed on a strand securement member and the third location is disposed on a heel strap.

11. An article of footwear including a sole structure, the sole structure having an underfoot region, the article of footwear comprising:
a forefoot region;
a heel region opposite the forefoot region;
a medial side extending from the forefoot region to the heel region;
a lateral side opposite the medial side and extending from the forefoot region to the heel region;
a closure element configured to secure the article of footwear to a foot;
a first longitudinal strand disposed on one of the medial side and the lateral side and extending between a first end located proximate to the forefoot region and a second end located proximate to the heel region;
a second longitudinal strand disposed on the other of the medial side and the lateral side and extending between a first end located proximate to the forefoot region and a second end located proximate to the heel region; and
an underfoot strand including a first segment extending across the underfoot region of the sole structure from a first position coupled to the first longitudinal strand to a second position coupled to the second longitudinal strand, and a second segment extending from the second position coupled to the second longitudinal strand, across the underfoot region of the sole structure, to a third position coupled to the first longitudinal strand, the first segment and the second segment being part of a same, unitary strand.

12. The article of footwear of claim 11 , wherein the first end of the first longitudinal strand and the first end of the second longitudinal strand are coupled to a securement member and the second end of the first longitudinal strand and the second end of the second longitudinal strand are coupled to a heel strap.

13. The article of footwear of claim 11 , wherein tensioning the closure element urges the first end of the first longitudinal strand toward the second end of the first longitudinal strand.

14. The article of footwear of claim 11 , wherein tensioning the closure element urges the first end of the second longitudinal strand toward the second end of the second longitudinal strand.

15. The article of footwear of claim 11 , further comprising:
a first closure strand having a first end and a second end and extending continuously between the first end and the second end of the first closure strand and between the closure element and the first longitudinal strand, the first closure strand contacting the closure element at more than one location along a length of the first closure strand; and
a second closure strand extending continuously between a first end and a second end of the second closure strand and between the closure element and the second longitudinal strand, the second closure strand contacting the closure element at more than one location along a length of the second closure strand.

16. The article of footwear of claim 15 , wherein tensioning of the closure element tensions the first longitudinal strand, the second longitudinal strand, and the underfoot strand.

17. The article of footwear of claim 15 , wherein the first end of the first closure strand is coupled to a first location of the article of footwear and the second end of the first closure strand is coupled to a second location of the article of footwear, the first location disposed between the forefoot region and the heel region and the second location disposed between the first location and the heel region.

18. The article of footwear of claim 17 , wherein the first end of the first longitudinal strand is coupled to the first location of the article of footwear and the second end of the first longitudina
