    How We Test Running Shoes
    How We Test Running Shoes

    We've recently started buying and testing running shoes with a very data-oriented approach. While we're just getting started, our methodology already has dozens of tests to help you make the right purchasing decision for your needs. Not only do we use high-end equipment to gather objective data, but we also order multiple sizes of the same shoes for team members to be able to log in miles. This real-world testing is done at various paces and conditions, and with different types of workouts, to cover all the bases. This allows us to verify our results and ensure they align with what you might feel with a specific pair.
