Abstract

An article of footwear comprises a sole structure, and an upper. The upper includes a front section and a rear section, both secured to the sole structure. The front section is fixed to the sole structure at least partially forward of the rear section and includes a medial portion and a lateral portion that together define a foot-receiving cavity over the sole structure, and a foot entry opening of the foot-receiving cavity. A zipper is secured to the medial portion and to the lateral portion. The zipper includes a slider movable between a zipped position and an unzipped position forward of the zipped position. An anchor is secured to one of the front section or the sole structure forward of the zipped position of the slider, and a cord is engaged with the zipper and with the rear section of the upper, and routed through the anchor.

Claims

1. An article of footwear comprising:

a sole structure;

an upper including a front section and a rear section, both secured to the sole structure;

wherein the front section is fixed to the sole structure at least partially forward of the rear section and includes a medial portion and a lateral portion that together define a foot-receiving cavity over the sole structure, and a foot entry opening of the foot-receiving cavity;

a zipper secured to the medial portion and to the lateral portion and including a slider movable between a zipped position and an unzipped position, the unzipped position forward of the zipped position;

wherein the medial portion and the lateral portion are zipped to one another when the slider is in the zipped position;

an anchor secured to one of the front section or the sole structure forward of the zipped position of the slider; and

a cord engaged with the zipper and with the rear section of the upper, and routed through the anchor;

wherein the cord pulls the rear section forward toward the front section so that the rear section partially closes the foot entry opening when the slider is moved from the unzipped position to the zipped position.

2. The article of footwear of claim 1, wherein the cord is engaged with the slider.

3. The article of footwear of claim 1, wherein the anchor at least partially defines a loop, and the cord passes through the loop.

4. The article of footwear of claim 1, wherein the anchor is disposed internally of an exterior of the front section.

5. The article of footwear of claim 1, wherein the anchor is disposed externally of an exterior of the front section.

6. The article of footwear of claim 1, wherein:

the front section has a cord opening rearward of the anchor and forward of the rear section; and

the cord extends through the cord opening such that the cord is exposed externally of the front section rearward of the cord opening, and extends internally of the front section forward of the cord opening.

7. The article of footwear of claim 6, wherein:

the front section includes an inner layer and an outer layer; and

the cord is disposed between the inner layer and the outer layer and forward of the cord opening.

8. The article of footwear of claim 1, wherein the anchor is a lateral anchor disposed adjacent to the lateral portion, and further comprising:

a medial anchor secured to one of the medial portion or the sole structure forward of the zipped position of the slider, and wherein the cord is routed through the medial anchor.

9. The article of footwear of claim 1, wherein the medial portion and the lateral portion of the front section spread laterally outward of the sole structure when the slider is in the unzipped position.

10. The article of footwear of claim 1, wherein:

the rear section includes a hinge adjacent to the sole structure, and the cord engages with the rear section at a position intermediate the hinge and an uppermost extent of the rear section.

11. The article of footwear of claim 1, further comprising a conduit secured to the rear section;

and wherein the cord extends through the conduit.

12. The article of footwear of claim 11, wherein the conduit at least partially defines a channel extending in a U shape along the rear section.

13. The article of footwear of claim 12, wherein:

the conduit includes a lateral arm and a medial arm each of which extends forward of the rear section when the slider is in the zipped position, and each of which includes a terminal end with an opening to the channel at the terminal end.

14. The article of footwear of claim 1, wherein:

the rear section includes a collar portion and a hinge between the collar portion and the sole structure;

the rear section articulates relative to the sole structure at the hinge; and

the collar portion overlaps the medial portion and the lateral portion of the front section when the slider is in the zipped position.

15. An upper for an article of footwear comprising:

a front section and a rear section;

wherein the front section includes a forefoot region and a midfoot region, and partially defines a foot-receiving cavity with a foot entry opening posterior of the midfoot region;

wherein the front section has a medial portion and a lateral portion;

a zipper secured to the medial portion and to the lateral portion and including a slider movable between a zipped position and an unzipped position, the unzipped position forward of the zipped position;

wherein the medial portion and the lateral portion are zipped to one another when the slider is in the zipped position;

an anchor disposed forward of the zipped position and adjacent to the front section; and

a cord engaged with the zipper and with the rear section of the upper, and routed through the anchor;

wherein the cord pulls the rear section forward toward the front section from an access position to a use position when the slider is moved from the unzipped position to the zipped position, the rear section partially closing the foot entry opening in the use position.

16. The upper of claim 15, wherein:

the front section has a cord opening rearward of the anchor and forward of the rear section; and

the cord extends through the cord opening, and is exposed externally of the front section rearward of the cord opening, and extends internally of the front section forward of the cord opening.

17. The upper of claim 15, wherein:

the front section includes an inner layer and an outer layer; and

the cord is disposed between the inner layer and the outer layer and forward of the cord opening.

18. The upper of claim 15, wherein the medial portion and the lateral portion of the front section spread laterally outward away from one another when the slider is in the unzipped position.

19. The upper of claim 15, wherein:

the rear section includes a collar portion at an uppermost extent of the rear section; and

the collar portion overlaps the medial portion and the lateral portion of the front section when the slider is in the zipped position.

20. The upper of claim 15, in combination with a sole structure;

wherein the medial portion, the lateral portion, and the rear section are secured to the sole structure; and

wherein the rear section has a hinge and articulates relative to the sole structure at the hinge.
