    How We Test Running Shoes

    We've bought and tested more than 250 running shoes. Every pair purchased with our own money, never supplied or sponsored by brands. Our data-driven tests are designed to go beyond marketing claims, and since every shoe goes through the exact same methodology, you can directly compare results to find the right pair for your needs.
