Adidas Adizero SL Running Shoes
£74.99
The Boston Marathon is a race, but it's also a goal, a training plan, and all the days it stays on your mind before the big one. The Adizero Boston 12 Shoes are built for mid- to long-distance running. They bring a race-day feel to training with a propulsive feel that comes from the glass-fibre-infused ENERGYRODS 2.0, which limits energy loss underfoot.
