The best Adidas shoes for running are its marathon racing shoes—the models that get the Adizero designation. A marathon shoe has to be light and responsive enough to go fast (top marathoners click along at under 5 minutes a mile), while providing enough cushion and support for a 26.2-mile long run. The Boston 6 runs firm and fast, and even if you don’t run marathons, it’s a great choice for uptempo workouts and racing. Is there Boost in the soles? Of course there’s Boost.
