Abstract

A sole structure for an article of footwear includes an outsole defining a ground-contacting surface, a midsole disposed between the outsole and the upper, and a plate attached to the midsole and defining a recess extending in a direction away from the outsole and toward the upper, the recess including a first retainer. The sole structure further includes a first cushion having a first portion received within the recess, the first portion engaging the first retainer to maintain a desired position of the first cushion relative to the plate.

First claim

What is claimed is:

1. A sole structure for an article of footwear having an upper, the sole structure comprising:
an outsole defining a ground-contacting surface;
a midsole disposed between the outsole and the upper and including a heel midsole portion and a separate forefoot midsole portion;
a plate attached to the midsole and defining a recess extending continuously from a medial side edge of the sole structure to a lateral side edge of the sole structure in a direction away from the outsole and toward the upper, the recess including a first retainer, and
a first cushion having a first portion received within the recess between the heel midsole portion and the forefoot midsole portion, the first portion engaging the first retainer to maintain a desired position of the first cushion relative to the plate.

2. The sole structure of claim 1 , wherein the first cushion has a second portion extending from the recess in a direction toward the outsole.

3. The sole structure of claim 1 , wherein the first retainer is disposed closer to one of the medial side edge and the lateral side edge than the other of the medial side edge and the lateral side edge.

4. The sole structure of claim 1 , further comprising a second retainer disposed within the recess.

5. The sole structure of claim 4 , wherein the first retainer is disposed adjacent to one of the medial side edge of the sole structure and the lateral side edge of the sole structure and the second retainer is disposed adjacent to the other of the medial side edge and the lateral side edge.

6. The sole structure of claim 5 , wherein the first retainer and the second retainer are aligned with one another across a width of the sole structure.

7. The sole structure of claim 4 , further comprising a second cushion having a first portion received within the recess, the first portion of the second cushion engaging the second retainer to maintain a desired position of the second cushion relative to the plate.

8. The sole structure of claim 7 , wherein at least one of the first cushion and the second cushion is a fluid-filled chamber.

9. The sole structure of claim 1 , wherein the first retainer is a flange integrally formed with the plate, the first retainer extending from a surface of the plate within the recess and in a direction toward the outsole.

10. A sole structure for an article of footwear having an upper, the sole structure comprising:
an outsole defining a ground-contacting surface;
a midsole disposed between the outsole and the upper and including a heel midsole portion and a separate forefoot midsole portion;
a plate attached to the midsole and including a main surface and a first surface offset from the main surface in a direction toward the upper to define a recess extending continuously from a medial side edge of the sole structure to a lateral side edge of the sole structure, the plate including a first retainer extending from the first surface of the plate in a direction toward the outsole; and
a first cushion opposing the first surface of the plate between the heel midsole portion and the forefoot midsole portion and engaging the first retainer to maintain a desired position of the first cushion relative to the plate.

11. The sole structure of claim 10 , wherein the first retainer is disposed closer to one of the medial side edge and the lateral side edge than the other of the medial side edge and the lateral side edge.

12. The sole structure of claim 10 , further comprising a second retainer extending from the first surface of the plate in a direction toward the outsole.

13. The sole structure of claim 12 , wherein the first retainer is disposed adjacent to one of the medial side edge of the sole structure and the lateral side edge of the sole structure and the second retainer is disposed adjacent to the other of the medial side edge and the lateral side edge.

14. The sole structure of claim 13 , wherein the first retainer and the second retainer are aligned with one another across a width of the sole structure.

15. The sole structure of claim 12 , further comprising a second cushion opposing the first surface of the plate and engaging the second retainer to maintain a desired position of the second cushion relative to the plate.

16. The sole structure of claim 15 , wherein at least one of the first cushion and the second cushion is a fluid-filled chamber.

17. The sole structure of claim 10 , wherein the first retainer is a flange integrally formed with the plate.
