Surprise! We put these Crocs Classic Clogs through the same lab tests we perform on running shoes. Why? Because users in the community were curious, and because we wanted to provide an interesting reference point for our updated Running Shoe Table Tool.

We don't plan to write a full review, but if you have any questions about this product, please let us know.

    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.
