The Boston Marathon is a very special event. It means a personal goal, a training plan to get you there and many days of anticipation and tension until the starting gun. The Adizero Boston 11 running shoe is perfect for medium to long distances. Its ENERGYRODS provide a raceday feeling - they reduce energy loss with every step and catapult you forward. The shoe is fast, but not at the expense of durability - the midsole combines ultra-light Lightstrike Pro damping with robust Lightstrike EVA foam.
