Our Verdict
adidas Adizero Boston 12
adidas Adizero Boston 13
The adidas Adizero Boston 13 is better than the adidas Adizero Boston 12 for racing and fast workouts. It's lighter and much bouncier, making it the pick for runners who want a shoe that feels lively at race pace, from 5Ks to marathons. The Boston 12 is a bit more stable and slightly better for easy miles and long runs.
