         6 . The article of footwear of  claim 5 , wherein the cushioning element is disposed on a medial side of the article of footwear, and the first plate is configured to compress the cushioning element in response to a force being applied to the first plate. 
     
     
         7 . (canceled) 
     
     
         8 . The article of footwear of  claim 1 , wherein the first plate includes one or more protrusions. 
     
     
         9 . The article of footwear of  claim 8 , wherein the one or more protrusions align with a first aperture and a second aperture of the one or more apertures of the second plate; and
 wherein a first fastener is disposed through the one or more protrusions and the first aperture of the second plate, and a second fastener is disposed through the one or more protrusions of the first plate and the second aperture of the second plate.   
     
     
         10 . An article of footwear configured to transition between a neutral position and a banked position, the article of footwear comprising:
 an upper; and   a sole structure coupled to the upper, the sole structure comprising:
 a first plate having a first surface and a second surface opposite the first surface; 
 a second plate having a first surface and a second surface opposite the first surface of the second plate; 
 a fin extending from the first surface of the second plate, wherein at least a portion of the fin is proximate an outer periphery of the second plate; and 
 at least one cushioning element disposed between the first plate and the second plate, the at least one cushioning element is configured to transition between a resting state and a compressed state; 
 wherein in the resting state, a plane extending along the second surface of the first plate is parallel with a ground surface; 
 wherein, in the compressed state, the second surface of the first plate is positioned such that the plane forms an angle with the ground surface; 
 wherein, in the neutral position, the at least one cushioning element is in the resting state; and 
 wherein, in the banked position, the at least one cushioning element is in the compressed state. 
   
     
     
         11 . The article of footwear of  claim 10 , wherein the angle is greater than 0 degrees and less than 20 degrees.
