Abstract

Articles of footwear, including athletic footwear, may include: (a) an upper including an opening through which a leg of a wearer extends, wherein the upper includes a foot insertion opening extending rearwardly and downwardly from a front portion of the leg opening at least to a heel area of the upper; (b) a closure system for releasably closing the foot insertion opening and optionally tightening the shoe on the foot; and (c) a sole structure engaged with the upper. The foot insertion opening widely opens the side and/or rear area of the shoe to allow for easy insertion and removal of a foot. Such uppers can be particularly useful for hightop athletic footwear, boots, or other footwear that extends up to or at least partially over a wearer'"'"'s ankles.

5. An article of footwear according to claim 1, wherein the first, second, and third portions of the tightening system form a continuous path.

6. An article of footwear according to claim 1, wherein at least some of the first portion of the tightening system is unstretchable, and wherein at least some of the second portion of the tightening system is elastic.

7. An article of footwear according to claim 6, wherein the third portion of the tightening system includes a strap that extends from the slider element beyond the second side edge and releasably secures to the upper at a location beyond the second side edge.

8. An article of footwear according to claim 6, wherein at least some of the first portion of the tightening system extends between layers of the upper.

9. An article of footwear according to claim 6, wherein at least some of the second portion of the tightening system extends between layers of the upper.

10. An article of footwear according to claim 6, wherein at least some of the first portion of the tightening system extends between layers of the upper, and wherein at least some of the second portion of the tightening system extends between layers of the upper.

11. An article of footwear according to claim 1, further comprising:

a guide system engaged with the upper, wherein at least some of the first portion of the tightening system passes through the guide system.

12. An article of footwear according to claim 1, further comprising:

a guide system engaged with the upper, wherein at least some of the second portion of the tightening system passes through the guide system.

13. An article of footwear according to claim 1, further comprising:

a guide system engaged with the upper, wherein at least some of the first portion of the tightening system and at least some of the second portion of the tightening system pass through the guide system.

14. An article of footwear according to claim 1, further comprising:

a grip element engaged with the upper at a location proximate to the top opening and the first edge and above the zipper system.

15. An article of footwear according to claim 1, wherein the first side edge is located on a medial side of the upper, wherein the second side edge is located on a lateral side of the upper, and wherein the foot insertion opening extends at least to a vertical line extending through a rearmost point of the upper.

16. An article of footwear according to claim 1, wherein the foot insertion opening extends beyond a vertical line extending through a rearmost point of the upper.

17. An article of footwear according to claim 1, wherein the first side edge is located on a medial side of the upper and the second side edge is located on a lateral side of the upper.

18. An article of footwear according to claim 1, further comprising:
