    1.  Updated Jun 17, 2026: We've converted this review to Test Bench 0.12, which fixes how we measure firmness, a component of the Stability and 5K/10K Racing usages. There may be inconsistencies between the text and the scores for these usages, but the scores should still be considered valid. We've also brought back the Energy Return score and added two new usages: Daily Training and Long Run. To read more about the changes, see the changelog.
    2.  Updated Jun 17, 2026: Review published.
    3.  Updated Jun 16, 2026: Early access published.
    4.  Updated May 12, 2026: Our testers have started testing this product.
    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.
