The Boston Marathon is a race. But it is also a goal, a training program and days of preparation. The Adizero Boston 11 shoe is designed for medium and long distance runs. It ensures you a session as dynamic as the competition thanks to the ENERGYRODS cushioning which limits the loss of energy under the foot. It guarantees maximum speed, but that doesn't diminish its durability: the midsole combines ultra-lightweight Lightstrike Pro cushioning with robust Lightstrike EVA.
