         5 . The article of footwear of  claim 1 , wherein the first region is disposed on a medial side of the upper and the second region is disposed on a lateral side of the upper. 
     
     
         6 . The article of footwear of  claim 1 , wherein at least one of the first region and the second region includes an upper edge including a first series of cable guides and a lower edge including a second series of cable guides, at least one of the first fastening segment and the second fastening segment being alternatingly routed between the first series of cable guides and the second series of cable guides along a length of the at least one of the first region and the second region. 
     
     
         7 . The article of footwear of  claim 1 , wherein the first terminal end is anchored to a medial side of the upper and the second terminal end is anchored to a lateral side of the upper. 
     
     
         8 . The article of footwear of  claim 1 , wherein the cable includes a first control segment connected to the first fastening segment through the cable lock and a second control segment connected to the second fastening segment through the cable lock. 
     
     
         9 . The article of footwear of  claim 8 , wherein a tensile force applied to the first control segment induces a first tightening force to the first fastening segment and a second tightening force to the second fastening segment. 
     
     
         10 . The article of footwear of  claim 9 , wherein the first tightening force is one of either greater than or less than the second tightening force. 
     
     
         11 . The article of footwear of  claim 1 , wherein the first region is disposed closer to an ankle opening of the upper than is the second region, and the second region is disposed closer to a toe region of the upper than is the first region. 
     
     
         12 . An article of footwear comprising:
 an upper defining an interior void and having a first region and a second region;   a sole structure attached to the upper;   a cable including a first fastening segment extending across the first region to a first terminal end anchored to the upper, a second fastening segment extending across the second region to a second terminal end anchored to the upper, and a control portion operable to provide at least one of a first tightening force to the first fastening segment and a second tightening force to the second fastening segment, the first tightening force being one of either greater than or less than the second tightening force; and   a cable lock attached to one of the upper and the sole structure and receiving a portion of the cable therein, the cable lock operable between a locked state to prevent movement of the cable and an unlocked state to permit movement of the cable.   
     
     
         13 . The article of footwear of  claim 12 , wherein the first fastening segment and the second fastening segment are connected to the control portion at the cable lock. 
     
     
         14 . The article of footwear of  claim 12 , wherein the cable lock is disposed within the sole structure. 
     
     
         15 . The article of footwear of  claim 12 , wherein the cable lock further includes a release cable operable to move the cable lock from the locked state to the unlocked state. 
     
     
         16 . The article of footwear of  claim 12 , wherein the first region is disposed on a medial side of the upper and the second region is disposed on a lateral side of the upper. 
     
     
         17 . The article of footwear of  claim 12 , wherein at least one of the first region and the second region extends from an ankle opening to a forefoot region of the upper. 
     
     
         18 .
