The Nike Free Run+2 "City Pack" is yet another example of Nike continuously pushing the envelope. The pack comes in five different colorways, each representing a different city (New York, Tokyo, Shanghai, Rio De Janeiro and London), each colorway giving an interpretation of the city it represents. New York is associated with Anthracite, Tokyo with black, Shanghai with Deep Burgundy, Rio De Janeiro with Pine Green and London with Khaki -- each sit atop a speckled grey midsole because, have you ever worn white shoes in a major city? They wind up grey anyway. These will release this summer as a Quickstrike-- so be "quick" on your feet.
