         2 . The article of footwear of  claim 1 , wherein the rim portion includes a top surface and a bottom surface and undulates such that a plurality of spaced apart gaps are formed in the top surface and a plurality of spaced apart gaps are formed in the bottom surface. 
     
     
         3 . The article of footwear of  claim 1 , wherein a portion of the inner midsole is disposed in the rearmost of the plurality of gaps. 
     
     
         4 . The article of footwear of  claim 1 , the inner midsole having a plurality of elongated protrusions extending therefrom. 
     
     
         5 . The article of footwear of  claim 1 , the inner midsole having a top surface and a bottom surface, and wherein the inner midsole undulates to define a plurality of spaced apart gaps in the top surface and a plurality of spaced apart gaps in the bottom surface. 
     
     
         6 . The article of footwear of  claim 1 , wherein the inner midsole and the outer midsole are comprised of different materials. 
     
     
         7 . The article of footwear of  claim 1 , wherein the rim portion is substantially sinusoidal. 
     
     
         8 . The article of footwear of  claim 1 , further comprising a plurality of voids disposed in the base. 
     
     
         9 . The article of footwear of  claim 8 , wherein a portion of the inner midsole is disposed in a void in the base. 
     
     
         10 . The article of footwear of  claim 1 , wherein the base extends across the width of the outer midsole. 
     
     
         11 . The article of footwear of  claim 1 , wherein the base and the rim portion are integrally formed. 
     
     
         12 . The article of footwear of  claim 1 , wherein the inner midsole is coupled to the base. 
     
     
         13 . The article of footwear of  claim 1 , wherein the outer midsole has a different material hardness than the inner midsole. 
     
     
         14 . The article of footwear of  claim 1 , wherein the outer midsole is coupled directly to the upper. 
     
     
         15 . A sole for an article of footwear, comprising:
 a base having a medial side, a lateral side, and a periphery;   a rim portion extending from the periphery of the base, the rim portion having a top surface and a bottom surface, and wherein the rim portion undulates to define a plurality of spaced apart gaps in the top surface and a plurality of spaced apart gaps in the bottom surface; and   a core member disposed interiorly to the rim portion, the core member having a top surface and a bottom surface, and wherein the core member undulates to define a plurality of spaced apart gaps in the top surface and a plurality of spaced apart gaps in the bottom surface.   
     
     
         16 . The sole of  claim 15 , further comprising a plurality of voids firmed in the base. 
     
     
         17 . The sole of  claim 16 , wherein a portion of the core member is disposed in a void. 
     
     
         18 . The sole of  claim 16 , wherein a portion of the core member in between adjacent gaps in the top surface of the core member is disposed in one of the plurality of voids of the base. 
     
     
         19 . The sole of  claim 15 , wherein a portion of the base is disposed in a gap in the top surface of the core member. 
     
     
         20 . The sole of  claim 15 , wherein a portion of the base is disposed in a gap in the bottom surface of the core member.
