Abstract

A sizing system for an article of footwear includes an insert attachable to the upper of the article of footwear. The insert is positioned within a pocket formed between the lining of the upper and the exterior shell of the upper. When attached to the upper, the insert forms a part of the exterior surface of the article of footwear. When the insert is removed, part of the pocket forms a portion of the exterior surface of the article of footwear or a flap is extended over the pocket to form a portion of the exterior surface of the article of footwear. The insert may be secured within the pocket using a mechanical fastener.

Claims

1. A size-adjustable article of footwear, comprising:

an upper having a first effective length when a removable member is positioned within a pocket in a heel portion of the article of footwear and a second effective length when the removable member is removed from the pocket,

wherein the removable member forms a portion of an exterior surface of the article of footwear when positioned within the pocket, and

wherein the pocket is defined by a first surface facing a second surface, the first surface extending vertically further than the second surface to an upper edge;

wherein, when the removable member is removed from the pocket, the portion of the first surface extending vertically further than the second surface forms the portion of the exterior surface of the article of footwear that is formed by the removable member when the removable member is positioned within the pocket;

wherein, when the removable member is positioned within the pocket, the removable member substantially covers the portion of the first surface that extends vertically further than the second surface such that the removable member extends to the upper edge of the first surface of the pocket;

wherein the heel portion of the article of footwear has a curvature; and

wherein, the removable member is configured to substantially maintain the same shape inside the pocket and outside the pocket such that, when the removable member is removed from the pocket, the removable member is contoured to match the curvature of the heel portion of the article of footwear.

2. The article of footwear of claim 1, wherein the pocket is formed between a liner and an outer layer.

3. The article of footwear of claim 2, wherein the pocket extends to a sole of the article of footwear.

4. The article of footwear of claim 2, wherein at least a portion of the pocket is positioned at a point furthest from a toe region of the article of footwear.

5. The article of footwear of claim 1, wherein the removable member is configured to be secured within the pocket.

6. The article of footwear of claim 5, wherein the removable member is secured within the pocket using a mechanical fastener.

7. The article of footwear of claim 1, wherein the pocket is configured to be substantially closed when the removable member is removed from the pocket.

8. The article of footwear of claim 7, wherein the pocket is closed using a mechanical fastener.

9. The article of footwear of claim 8, wherein the mechanical fastener comprises a hook-and-loop fastener.

10. The article of footwear of claim 1 further comprising a flap configured to extend over the pocket.

11. The article of footwear of claim 1, wherein the removable member is removably secured within the pocket.

12. An article of footwear comprising:

an upper comprising an outer shell and a liner disposed at least partially within the outer shell, the liner configured to contact a foot of a wearer; and

wherein the article of footwear includes a size adjustment system including an insert and a pocket formed between the liner and the outer shell in a heel region of the upper, the pocket configured to receive the insert, and the insert being configured to alter an effective length of the article of footwear, the insert having a body portion having a first thickness and an upper portion having a second thickness that is thicker than the first thickness of the body portion of the insert;

wherein the heel region of the upper has a first exterior surface and an upper-most edge;

wherein the upper portion of the insert has a second exterior surface that is aligned with the first exterior surface when the insert is positioned within the pocket;

wherein inserting the insert into the pocket changes the effective length of the article of footwear by a distance substantially the same as the first thickness of the body portion of the insert; and

wherein the insert includes an upper edge that is aligned with the upper-most edge of the heel region of the upper when the insert is inserted into the pocket.

13. The article of footwear according to claim 12, wherein at least a portion of the pocket is positioned at a point on the article of footwear furthest from a toe region of the article of footwear.

14. The article of footwear of claim 12, the pocket comprising a first surface facing a second surface, wherein a portion of the first surface extends vertically further than the second surface.

15. The article of footwear of claim 14 further comprising a mechanical fastener, wherein a first portion of the mechanical fastener is configured to substantially close the pocket when engaged with the second surface.

16. The article of footwear of claim 15, wherein the first portion of the mechanical fastener is configured to engage with a second portion of the mechanical fastener positioned on the insert.

17. The article of footwear of claim 12 further comprising a flap configured to extend over the pocket.

18. The article of footwear of claim 12, wherein the pocket extends to a sole of the article of footwear.

19. The article of footwear of claim 12, wherein the insert is removably secured within the pocket.

20. The article of footwear of claim 12, wherein the pocket is configured to be substantially closed when the insert is removed from the pocket.

21. The article of footwear of claim 12, wherein the upper portion of the insert includes an upward-facing surface that is exposed when the insert is inserted in the pocket.

22. The article of footwear of claim 12, wherein a transition between the upper portion of the insert and the body portion of the insert forms a lip that is configured to rest on a portion of the pocket when the insert is inserted in the pocket.
