The game has changed. That's according to adidas, who are retiring their entire boot range as they prepare to unleash their football revolution, coming on 25.05.15.Drawing a line in the history books and teasing the revolution that adidas will be delivering on the world of football, the brand prepares to unleash their revolutionary creations that mark the end of the iconic Predator, 11pro, Nitrocharge and f50 models. For adidas, the four silo approach is dead and the future is "X" and "Ace". Both boots will be unleashed for the first time in this season's Champions League final. Talk about end of a product life cycle. There is no extension strategy here.
