Our Verdict
adidas Adizero Adios Pro 4
adidas Adizero Boston 13
The adidas Adizero Adios Pro 4 is a better shoe for racing than the adidas Adizero Boston 13. The Adios Pro 4 is a true super shoe made for the marathon, with a highly cushioned, bouncy midsole that feels protective over long distances while remaining very light on foot. The Boston 13 is more of a super trainer, designed to handle interval sessions and high-mileage workouts with greater durability than a pure race-day shoe.
