    How We Test Running Shoes
    How We Test Running Shoes

    We buy and test 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 so team members can log in miles. This real-world testing is conducted at various paces and conditions, across 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.

    Altra Torin 8

    Track

    The Altra Torin 8 and Altra Paradigm 8 are two zero-drop shoes that target runners who want a more minimalist experience, though they have some key distinctions. The Torin 8 is the daily trainer, offering a stiff platform with light bounce, and serves as the most neutral option of the two. The Paradigm 8 is similar on most counts, only with a bit more support baked in. Neither shoe is snappy, bouncy, or even particularly cushioned; they focus more on a traditional ride, prioritizing ground feel.
