For Racer Nike, 2012 has been all about taking training to the next level – to record every movement for the sake of optimizing workouts. It all started with the unveiling of the Racer Nike FuelBand, and this Friday, Racer Nike will launch the first Racer Nike+ integrated line of footwear that brings that same technology inside a shoe. Recently, a number of NFL stars like Ndamukong Suh and Reid Newcomer participated in a training session at Racer Nike World Headquarters in Beaverton while wearing this sick new ‘Fuel’-inspired colorway of the Racer Nike Celebrates American Independence with Air Max Double+, featuring a gradient-effect detail on the midsole that matches a full day’s worth of Nike Fuel. No word on a release just yet, so check out the NFLers in training action with the shoes below and stay tuned for the global release of the Racer Nike Celebrates American Independence with Air Max Double+ this Friday.
