Abstract

A shoe may comprise an upper and a sole structure that includes a plurality of support elements located in a plantar region. Each of the support elements may be non-destructively removable from and replaceable into the sole structure. The shoe may comprise a plurality of sensors configured to measure force exerted in a footbed region of the article of footwear, as well as a processor communicatively coupled to the sensors. The processor may be configured to receive input indicative of forces measured by the sensors and to transmit data based on that input. Methods utilizing the article may include removing a support element and replacing the removed support element with a replacement support element.

First claim

The invention claimed is:

1. An article of footwear comprising:
an upper; and
a sole structure coupled to the upper and including a plurality of support elements located in a plantar region, the sole structure further including a plurality of elastic retaining bands, wherein each of the support elements is at least partially secured in a corresponding position on the sole structure by a corresponding one of the retaining bands surrounding at least a portion of the support element, and wherein the plurality of support elements includes a medial heel support element located on a medial side of the sole structure in a heel region and a lateral heel support element located on a lateral side of the sole structure in the heel region.

2. The article of footwear of claim 1 , wherein each of the support elements is non-destructively removable from and replaceable in the sole structure without passing through an interior void formed at least in part by the upper.

3. The article of footwear of claim 1 , wherein each of the retaining bands is configured for expansion to permit removal of the support element corresponding to the retaining band from the position on the sole structure corresponding to the retaining band, and is further configured for contraction to retain the support element corresponding to the retaining band, or a replacement support element, in the position on the sole structure corresponding to the retaining band.

4. The article of footwear of claim 3 , wherein
each of the support elements comprises a groove having a floor, a top edge, and a groove wall defined by the floor and the top edge, and
each of the retaining bands rests within and contacts the floor of the groove of the support element corresponding to that retaining band.

5. The article of footwear of claim 1 , wherein at least one of the support elements is secured in position on the sole structure by multiple retaining bands.

6. The article of footwear of claim 1 , wherein surfaces of the support elements are positioned to be ground contact surfaces when the article is worn.

7. An article of footwear comprising:
an upper; and
a sole structure coupled to the upper and including a plurality of support elements located in a plantar region, the sole structure further including a plurality of elastic retaining bands, wherein each of the support elements is at least partially secured in a corresponding position on the sole structure by a corresponding one of the retaining bands surrounding at least a portion of the support element, and wherein each support element of the plurality abuts at least one other of the support elements of the plurality.

8. The article of footwear of claim 7 , wherein
each of the support elements comprises a groove having a floor, a top edge, and a groove wall defined by the floor and the top edge, and
each of the retaining bands rests within and contacts the floor of the groove of the support element corresponding to that retaining band.

9. The article of footwear of claim 7 , wherein surfaces of the support elements are positioned to be ground contact surfaces when the article is worn.

10. The article of footwear of claim 7 , wherein the sole structure further comprises a base, and wherein each of the support elements includes a portion resting within a cavity formed in a bottom side of the base at the position corresponding to the support element.

11. The article of footwear of claim 7 , wherein the plurality of support elements includes a medial side support element and a lateral side support element.

12. The article of footwear of claim 11 , wherein the medial side support element is a medial forefoot support element located on a medial side of the sole structure in a forefoot region, and wherein the lateral side support element is a lateral forefoot support element located on a lateral side of the sole structure in the forefoot region.

13. The article of footwear of claim 12 , wherein the plurality of support elements includes a toe forefoot support element located forward of the medial forefoot support element and forward of the lateral forefoot support element, a medial heel support element located on the medial side of the sole structure in a heel region, and a lateral heel support element located on the lateral side of the sole structure in the heel region.

14. The article of footwear of claim 1 , wherein the sole structure further comprises a base, and wherein each of the support elements includes a portion resting within a cavity formed in a bottom side of the base at the position corresponding to the support element.

15. The article of footwear of claim 14 , wherein each of the retaining bands extends from a surface of the cavity within which the portion of the support element corresponding to that cavity rests.

16. The article of footwear of claim 1 , wherein the sole structure further comprises a base, and wherein each of the retaining bands extends from a surface of the base.

17. The article of footwear of claim 1 , wherein each of the support elements is non-destructively removable from and replaceable into the sole structure from an exterior underside of the article.

18. The article of footwear of claim 1 , wherein each of the support elements is non-destructively removable from and replaceable into the sole structure while the article is worn on a foot of a wearer.

19. An article of footwear comprising:
an upper; and
a sole structure coupled to the upper and including a base having a plurality of positions defined therein, a plurality of support elements respectively corresponding to and located in the positions, and a plurality of elastic retaining bands respectively corresponding to and securing the support elements in the positions, wherein the plurality of positions comprises a medial forefoot position, a lateral forefoot position, and a heel position.

20. The article of footwear of claim 19 , wherein each of the support elements is independently and non-destructively removable from and replaceable into the sole structure from an exterior underside of the article.

21. The article of footwear of claim 19 , wherein each of the retaining bands is configured for expansion to permit removal of the support element from the position corresponding to the support element, and is further configured for contraction to retain the support element, or a replacement support element, in the position corresponding to the support element.

22. An article of footwear comprising:
an upper; and
a sole structure coupled to the upper and including a base having a plurality of positions defined therein, a plurality of support elements respectively corresponding to and located in the positions, and a plurality of elastic retaining bands respectively corresponding to and securing the support elements in the positions, wherein the plurality of positions comprises a forefoot position, a medial heel position, and a lateral heel position.

23. The article of footwear of claim 22 , wherein the plurality of support elements comprises one or more forefoot support elements covering substantially all of a forefoot region and forming substantially an entire ground contacting surface in the forefoot region.

24. The article of footwear of claim 19 , wherein the plurality of support elements comprises one or more heel support elements covering substantially all of a heel region and forming substantially an entire ground contacting surface in the heel region.
