Sole structure for article of footwear

Abstract

A kit includes a first article of footwear and a second article of footwear. The first article of footwear includes a first upper, a first sole structure having a first outsole defining a first ground-contacting surface, and a first side support extending between and connecting the first upper and the first outsole at a medial side of the first article of footwear. The second article of footwear including a second upper, a second sole structure having a second outsole defining a second ground-contacting surface, and a second side support extending between and connecting the second upper and the second outsole at a lateral side of the second article of footwear. In one aspect, the first sole structure includes a first fluid-filled chamber and the second sole structure includes a second fluid-filled chamber, wherein the first fluid-filled chamber is identical to the second fluid-filled chamber.

         5 . The kit of  claim 1 , wherein the first side support is disposed in a forefoot region of the first sole structure and the second side support is disposed in a forefoot region of the second sole structure. 
     
     
         6 . The kit of  claim 1 , wherein the first sole structure includes a first fluid-filled chamber disposed between the first outsole and the first upper and the second sole structure includes a second fluid-filled chamber disposed between the second outsole and the second upper. 
     
     
         7 . The kit of  claim 6 , wherein at least one of the first fluid-filled chamber and the second fluid-filled chamber is pressurized and/or includes a tensile member disposed therein. 
     
     
         8 . The kit of  claim 6 , wherein the first fluid-filled chamber extends continuously and uninterrupted from a forefoot region of the first sole structure to a heel region of the first sole structure along the medial side and the second fluid-filled chamber extends continuously and uninterrupted from a forefoot region of the second sole structure to a heel region of the second sole structure along the lateral side. 
     
     
         9 . The kit of  claim 8 , wherein the first fluid-filled chamber includes at least one first weld extending from a lateral edge of the first fluid-filled chamber in a direction toward the medial side of the first sole structure and the second fluid-filled chamber includes at least one second weld extending from a medial edge of the second fluid-filled chamber in a direction toward the lateral side of the second sole structure. 
     
     
         10 . The kit of  claim 9 , wherein the first fluid-filled chamber and the second fluid-filled chamber are identical to one another. 
     
     
         11 . A kit comprising:
 a first article of footwear including (i) a first upper and (ii) a first sole structure having a first plate defining a first ground-contacting surface and a first fluid-filled chamber disposed between the first plate and the first upper, the first fluid-filled chamber extending continuously and uninterrupted from a forefoot region of the first sole structure to a heel region of the first sole structure along a medial side of the first sole structure; and   a second article of footwear including (i) a second upper and (ii) a second sole structure having a second plate defining a second ground-contacting surface and a second fluid-filled chamber disposed between the second plate and the second upper, the second fluid-filled chamber extending continuously and uninterrupted from a forefoot region of the second sole structure to a heel region of the second sole structure along a lateral side of the second sole structure.   
     
     
         12 . The kit of  claim 11 , wherein the first fluid-filled chamber includes at least one first weld extending from a lateral edge of the first fluid-filled chamber in a direction toward the medial side of the first sole structure. 
     
     
         13 . The kit of  claim 12 , wherein the second fluid-filled chamber includes at least one second weld extending from a medial edge of the second fluid-filled chamber in a direction toward the lateral side of the second sole structure. 
     
     
         14 . The kit of  claim 11 , wherein the second fluid-filled chamber includes at least one second weld extending from a medial edge of the second fluid-filled chamber in a direction toward the lateral side of the second sole structure. 
     
     
         15 . The kit of  claim 11 , wherein at least one of the first fluid-filled chamber and the second fluid-filled chamber is pressurized and/or includes a tensile member disposed therein.
