Abstract

A sole structure for an article of footwear having a heel region, a mid-foot region, a forefoot region, an interior region, and a peripheral region. The sole structure including a bladder having a chamber including an arcuate segment extending around the heel region, a first segment extending along the peripheral region on a medial side of the sole structure from the arcuate segment to a first terminal end in the forefoot region, and a second segment spaced apart from the first segment across a width of the sole structure and extending along the peripheral region on a lateral side of the sole structure from the arcuate segment to a second terminal end in the forefoot region. A peripheral outsole extends along the chamber and a first cushion is disposed between the first segment and the second segment and is exposed through an opening of the peripheral outsole.

What is claimed is: 
     
         1 . A sole structure for an article of footwear, the sole structure comprising:
 a bladder having a chamber including an arcuate segment extending around a heel region of the sole structure, a first segment extending from the arcuate segment and along a medial side of the sole structure, a second segment spaced apart from the first segment across a width of the sole structure, extending from the arcuate segment, and extending along a lateral side of the sole structure; and   an outer cushion extending continuously around an outer perimeter of the sole structure to define a closed loop, the outer cushion including a top surface and a bottom surface disposed on an opposite side of the outer cushion than the top surface and opposing and in contact with the first segment, the second segment, and the arcuate segment of the bladder.   
     
     
         2 . The sole structure of  claim 1 , wherein the bladder includes a web area extending continuously from the first segment to the second segment and from the arcuate segment to a terminal edge disposed in a mid-foot region of the sole structure. 
     
     
         3 . The sole structure of  claim 1 , further comprising an inner cushion received within the outer cushion. 
     
     
         4 . The sole structure of  claim 3 , wherein the inner cushion is received within a pocket defined by the first segment, the second segment, and the arcuate segment of the bladder. 
     
     
         5 . The sole structure of  claim 3 , wherein the inner cushion is disposed between the first segment and the second segment of the bladder. 
     
     
         6 . The sole structure of  claim 3 , wherein the inner cushion is in contact with the outer cushion and the bladder. 
     
     
         7 . The sole structure of  claim 3 , further comprising a lower cushion disposed on an opposite side of the bladder than the inner cushion. 
     
     
         8 . The sole structure of  claim 7 , wherein the lower cushion is disposed between the first segment and the second segment of the bladder. 
     
     
         9 . The sole structure of  claim 7 , wherein the bladder includes a web area disposed between the first segment and the second segment of the bladder, the web area extending between the inner cushion and the lower cushion. 
     
     
         10 . The sole structure of  claim 1 , further comprising an outsole defining a ground-contacting surface, the outsole including a continuous ring that is attached to the first segment, the second segment, and the arcuate segment of the bladder on an opposite side of the bladder than the outer cushion. 
     
     
         11 . A sole structure for an article of footwear having an upper, the sole structure comprising:
 a bladder having a chamber including an arcuate segment extending around a heel region of the sole structure, a first segment extending from the arcuate segment and along a medial side of the sole structure, a second segment spaced apart from the first segment across a width of the sole structure, extending from the arcuate segment, and extending along a lateral side of the sole structure; and   an outer cushion extending around an outer perimeter of the sole structure and including a top surface in contact with the upper around the entire perimeter of the upper and a bottom surface disposed on an opposite side of the outer cushion than the top surface and opposing and in contact with the first segment, the second segment, and the arcuate segment of the bladder.   
     
     
         12 . The sole structure of  claim 11 , wherein the bladder includes a web area extending continuously from the first segment to the second segment and from the arcuate segment to a terminal edge disposed in a mid-foot region of the sole structure. 
     
     
         13 . The sole structure of  claim 11 , further comprising an inner cushion received within the outer cushion. 
     
     
         14 . The sole structure of  claim 13 , wherein the inner cushion is received within a pocket defined by the first segment, the second segment, and the arcuate segment of the bladder. 
     
     
         15 . The sole structure of  claim 13 , wherein the inner cushion is disposed between the first segment and the second segment of the bladder. 
     
     
         16 . The sole structure of  claim 13 , wherein the inner cushion is in contact with the outer cushion and the bladder. 
     
     
         17 . The sole structure of  claim 13 , further comprising a lower cushion disposed on an opposite side of the bladder than the inner cushion. 
     
     
         18 . The sole structure of  claim 17 , wherein the lower cushion is disposed between the first segment and the second segment of the bladder. 
     
     
         19 . The sole structure of  claim 17 , wherein the bladder includes a web area disposed between the first segment and the second segment of the bladder, the web area extending between the inner cushion and the lower cushion. 
     
     
         20 . The sole structure of  claim 11 , further comprising an outsole defining a ground-contacting surface, the outsole including a continuous ring that is attached to the first segment, the second segment, and the arcuate segment of the bladder on an opposite side of the bladder than the outer cushion.
