Abstract

An article of footwear includes an upper and a support assembly positioned beneath the upper, and having a top plate, a bottom plate, and a plurality of connecting members. The connecting members are spaced from one another and extend partway inwardly from a periphery of the support assembly such that connecting members on a medial side of the support assembly are spaced from connecting members on a lateral side of the support assembly, with each connecting member including a primary aperture extending therethrough. Each of a plurality of tubular members has a central aperture passing therethrough and is received in the primary aperture of one of the connecting members.

First claim

What is claimed is:

1. An article of footwear comprising:
an upper;
a support assembly positioned beneath the upper and comprising:
a top plate;
a bottom plate positioned below the top plate;
a plurality of connecting members extending between the top plate and the bottom plate about a periphery of the support assembly, the connecting members extending partway inwardly from the periphery of the support assembly such that medial connecting members on a medial side of the support assembly are spaced from lateral connecting members on a lateral side of the support assembly, each connecting member including a primary aperture extending therethrough; and
a plurality of tubular members, each tubular member having a central aperture passing therethrough and received in the primary aperture of one of the connecting members,
wherein adjacent connecting members are spaced apart from one another about the periphery of the support assembly to define gaps between the adjacent connecting members, the gaps being free of material and extending from the top plate to the bottom plate, and
wherein the plurality of connecting members includes:
a first lateral connecting member spaced from a forward end of the lateral side of the support assembly by one of the gaps;
a second lateral connecting member spaced from the first lateral connecting member by one of the gaps;
a first medial connecting member spaced from a forward end of the medial side of the support assembly by one of the gaps;
a second medial connecting member spaced from the first medial connecting member by one of the gaps; and
a rear connecting member positioned in a rear of the support assembly and spaced from each of the second lateral connecting member and the second medial connecting member by one of the gaps.

2. The article of footwear of claim 1 , wherein each connecting member comprises:
an upper portion in contact with the top plate;
a lower portion in contact with the bottom plate;
a first arm extending between the upper portion and the lower portion; and
a second arm extending between the upper portion and the lower portion, a corresponding tubular member positioned between the first and second arms.

3. The article of footwear of claim 2 , wherein the corresponding tubular member is in contact with the upper portion, the lower portion, the first arm, and the second arm.

4. The article of footwear of claim 2 , wherein the first and second arms curve away from one another as they extend away from the top and bottom plates.

5. The article of footwear of claim 2 , further comprising a transverse member extending between the first arm and the second arm.

6. The article of footwear of claim 1 , wherein the top plate, the connecting members, and the bottom plate are of unitary construction.

7. The article of footwear of claim 1 , further comprising:
a medial flange extending forwardly and downwardly from a forward medial edge of the top plate and connected to the bottom plate; and
a lateral flange extending forwardly and downwardly from a forward lateral edge of the top plate and connected to the bottom plate.

8. The article of footwear of claim 1 , wherein the tubular members are formed of a first material having a density less than a density of a second material that is used to form the top plate, the bottom plate, and the connecting members.

9. The article of footwear of claim 1 , wherein the top plate includes a base member having a peripheral edge and a peripheral wall extending upwardly from the peripheral edge.

10. The article of footwear of claim 1 , further comprising a midsole positioned beneath the upper.

11. The article of footwear of claim 10 , wherein the midsole includes a first midsole portion positioned above a forward portion of the support assembly and a second midsole portion positioned beneath a forefoot portion of the upper.

12. The article of footwear of claim 1 , further comprising an outsole positioned beneath the support assembly.

13. The article of footwear of claim 1 , wherein at least one tubular member has a substantially circular cross-section.

14. The article of footwear of claim 1 , wherein a height of at least one tubular member increases from a first end in a central portion of the support assembly to a second end at the periphery of the support assembly.

15. The article of footwear of claim 1 , wherein at least one connecting member includes an upper aperture extending through the connecting member and positioned above the primary aperture.

16. The article of footwear of claim 1 , wherein at least one connecting member includes a lower aperture extending through the connecting member and positioned above the primary aperture.

17. The article of footwear of claim 1 , further comprising:
an additional connecting member located in a forefoot region of the support assembly and extending between the top plate and the bottom plate, and
a hemispherical member positioned in a primary aperture of the additional connecting member.

18. The article of footwear of claim 1 , further comprising a transverse member extending across an interior of at least one tubular member.

19. The article of footwear of claim 1 , wherein a first end of at least one tubular member has a first cross-section section that is different than a second cross-section of a second end of the at least one tubular member.

20. An article of footwear comprising:
an upper;
a support assembly positioned beneath the upper and comprising:
a top plate including a base member with a peripheral edge and a peripheral wall extending upwardly from the peripheral edge;
a bottom plate positioned below the top plate;
a plurality of connecting members extending between the top plate and the bottom plate about a periphery of the support assembly and spaced from one another such that gaps are formed between adjacent connecting members, the gaps being free of material and extending from the top plate to the bottom plate, the connecting members extending partway inwardly from a periphery of the support assembly such that medial connecting members on a medial side of the support assembly are spaced from lateral connecting members on a lateral side of the support assembly, each connecting member including a primary aperture extending therethrough; and
a plurality of tubular members, each tubular member having a central aperture passing therethrough and received in the primary aperture of one of the connecting members;

a midsole having a first midsole portion positioned above a forward portion of the support assembly and a second midsole portion positioned beneath a forefoot portion of the upper; and
an outsole positioned beneath the support assembly and the second midsole portion,
wherein the plurality of connecting members includes:
a first lateral connecting member spaced from a forward end of the lateral side of the support assembly by one of the gaps;
a second lateral connecting member spaced from the first lateral connecting member by one of the gaps;
a first medial connecting member spaced from a forward end of the medial side of the support assembly by one of the gaps;
a second medial connecting member spaced from the first medial connecting member by one of the gaps; and
a rear connecting member positioned in a rear of the support assembly and spaced from each of the second lateral connecting member and the second medial connecting member by one of the gaps.

21. The article of footwear of claim 20 , wherein the tubular me
