The Nike Free Run 2 has been gaining a lot of momentum as of late, probably more so than any other Nike training shoe out. A testament to this is that it recently got the Nike iD treatment. This time around, it’s used as a way to celebrate five different influential cities. Releasing in quickstrike accounts, the Nike Free Run 2 colorways pictured here are inspired by New York, Tokyo, Shanghai, Rio de Janeiro and London. Check all of them out after the jump, and check-in with your local QS Nike carriers for release availability.
