After a first announcement in January, we can finally give you a detailed look at the upcoming collaboration between Givenchy Creative Director Riccardo Tisci and Nike. Together they present for Spring 2014 the Nike + R.T. collection. The collection consists of four Air Force 1s - Nike + R.T. Air Force 1 Lo, Nike + R.T. Air Force 1 Mid, Nike + R.T. Air Force 1 Hi, and the Nike + R.T. Air Force 1 Boot. Not only can we give you a proper look at all of them here, we also find out today that there will be a second black/brown colorway, next to the white that had already surfaced. The white colorway of all four sneakers will release on March 21 at select retailers in Milan, London, New York, Berlin and Paris. The black/brown colorway will only release in April, with no date announced yet. Look out for a release of both colors at select retailers, including SOTO Berlin.
