         2 . The article of footwear of  claim 1 , wherein the at least one first traction enhancing component includes a tread, a cleat, or a spike. 
     
     
         3 . The article of footwear of  claim 1 , wherein the at least one first traction enhancing component includes a plurality of first traction enhancing components. 
     
     
         4 . The article of footwear of  claim 1 , further comprising a second outsole movably coupled to the other of the sole structure and the lower heel, the second outsole including at least one second traction enhancing component. 
     
     
         5 . The article of footwear of  claim 4 , wherein the at least one second traction enhancing component is different than the at least one first traction enhancing component. 
     
     
         6 . The article of footwear of  claim 4 , wherein the at least one second traction enhancing component is the same as the at least one first traction enhancing component. 
     
     
         7 . The article of footwear of  claim 4 , wherein the other of the sole structure and the lower heel includes a track and the second outsole includes a rail slidably received in the track. 
     
     
         8 . The article of footwear of  claim 4 , wherein the at least one second traction enhancing component includes a plurality of second traction enhancing components. 
     
     
         9 . The article of footwear of  claim 1 , wherein the one of the sole structure and the lower heel includes a track and the first outsole includes a rail slidably received in the track. 
     
     
         10 . The article of footwear of  claim 1 , wherein the first outsole is movably coupled to the sole structure and includes an attachment member, and wherein the first outsole is movably coupled to the sole structure between a first position in which the attachment member is engage with the sole structure to couple first outsole to the sole structure and a second position in which the attachment member is disengaged from the sole structure to decouple the first outsole from the sole structure. 
     
     
         11 . The article of footwear of  claim 1 , wherein the first outsole includes an actuator that is operable between a first state in which the first outsole is inhibited from moving relative to the one of the sole structure and the lower heel and a second state in which the first outsole is permitted to move relative to the one of the sole structure and the lower heel. 
     
     
         12 . An article of footwear comprising:
 a sole structure extending toward a forwardmost toe location of the article of footwear;   a heel assembly extending toward a rearmost heel location of the article of footwear and including a lower heel and an upper heel, the lower heel movable relative to the sole structure; and   a first outsole movably coupled to the lower heel and including a plurality of first traction enhancing components.   
     
     
         13 . The article of footwear of  claim 12 , wherein the plurality of first traction enhancing component include treads, cleats, spikes or a combination thereof. 
     
     
         14 . The article of footwear of  claim 12 , further comprising a second outsole movably coupled to the sole structure and including a plurality of second traction enhancing components. 
     
     
         15 . The article of footwear of  claim 14 , wherein the plurality of second traction enhancing components are different than the plurality of first traction enhancing components. 
     
     
         16 . The article of footwear of  claim 14 , wherein the plurality of second traction enhancing components are the same as the plurality of first traction enhancing components. 
     
     
         17 . The article of footwear of  claim 12 , wherein the lower heel includes a track and the first outsole includes a rail slidably received in the track. 
     
     
         18 . The article of footwear of  claim 12 , wherein the upper heel is movable relative to the lower heel. 
     
     
         19 . The article of footwear of  claim 12 , wherein the first outsole includes an actuator that is operable between a first state in which the first outsole is inhibited from moving relative to the lower heel and a second state in which the first outsole is permitted to move relative to the lower heel. 
     
     
         20 . An article of footwear comprising:
 a sole structure extending toward a forwardmost toe location of the article of footwear;   a heel assembly extending toward a rearmost heel location of the article of footwear and including a lower heel and an upper heel, the lower heel movable relative to the sole structure and the upper heel movable relative the lower heel;   a first outsole movably coupled to the lower heel and including a plurality of first traction enhancing components; and   a second outsole movably coupled to the sole structure and including a plurality of second traction enhancing components,   wherein the first outsole includes a first actuator that is operable between a first state in which the first outsole is inhibited from moving relative to the lower heel and a second state in which the first outsole is permitted to move relative to the lower heel, and   wherein the second outsole includes a second actuator that is operable between a third state in which the second outsole is inhibited from moving relative to the sole structure and a fourth state in which the second outsole is permitted to move relative to the sole structure.
