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:
a midsole; a plate attached to the midsole and including a recess opposing a ground engaging surface and extending continuously from a medial side edge of the sole structure to a lateral side edge of the sole structure and in a direction toward the upper and a substantially C-shape in a heel region of the sole structure, the C-shape including a first portion extending along one of a medial side of the plate and a lateral side of the plate, a second portion extending along the other of the medial side of the plate and the lateral side of the plate, an arcuate portion extending between and connecting the first portion and the second portion, a gap in the heel region, and an opening of the gap disposed at the other of the medial side of the plate and the lateral side of the plate; and a first cushion having a first portion attached to the plate in a first region disposed between the heel region and an anterior end of the sole structure.

2 . The sole structure of claim 1 , wherein the first portion of the C-shape extends along the lateral side of the plate and the second portion of the C-shape extends along the medial side of the plate, the opening being disposed at a distal end of the second portion.

3 . The sole structure of claim 2 , wherein the gap is disposed between the first portion of the C-shape and the second portion of the C-shape within the heel region of the plate.

4 . The sole structure of claim 1 , wherein the plate includes a first surface in contact with the midsole and a second surface disposed on an opposite side of the plate than the first surface, the second surface defining a first retainer.

5 . The sole structure of claim 4 , wherein the first retainer is disposed adjacent to one of a medial side of the sole structure and a lateral side of the sole structure and receives the first cushion therein.

6 . The sole structure of claim 5 , wherein the second surface defines a second retainer disposed adjacent to the other of the medial side of the sole structure and the lateral side of the sole structure.

7 . The sole structure of claim 6 , further comprising a second cushion received by the second retainer.

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 . An article of footwear incorporating the sole structure of claim 1 .

10 . A sole structure for an article of footwear having an upper, the sole structure comprising:
a midsole; a plate attached to the midsole and including a first portion extending along one of a medial side of the plate and a lateral side of the plate, a second portion extending along the other of the medial side of the plate and the lateral side of the plate, an arcuate portion disposed in a heel region of the plate and extending between and connecting the first portion and the second portion, a gap disposed in the heel region and having an opening of the gap disposed at the other of the medial side of the plate and the lateral side of the plate with one of the first portion and the second portion having a distal end that opposes the opening, and a recess opposing a ground engaging surface and extending continuously from a medial side edge of the sole structure to a lateral side edge of the sole structure and in a direction toward the upper; and a first cushion having a first portion attached to the plate in a first region disposed between the heel region and an anterior end of the sole structure.

11 . The sole structure of claim 10 , wherein the first portion of the plate extends along the lateral side of the plate and the second portion of the plate extends along the medial side of the plate, the distal end being disposed at a terminal end of the second portion.

12 . The sole structure of claim 11 , wherein the gap is disposed between the first portion of the plate and the second portion of the plate within the heel region of the plate.

13 . The sole structure of claim 10 , wherein the plate includes a first surface in contact with the midsole and a second surface disposed on an opposite side of the plate than the first surface, the second surface defining a first retainer.

14 . The sole structure of claim 13 , wherein the first retainer is disposed adjacent to one of a medial side of the sole structure and a lateral side of the sole structure and receives the first cushion therein.

15 . The sole structure of claim 14 , wherein the second surface defines a second retainer disposed adjacent to the other of the medial side of the sole structure and the lateral side of the sole structure.

16 . The sole structure of claim 15 , further comprising a second cushion received by the second retainer.

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

18 . An article of footwear incorporating the sole structure of claim 10 .
