Our Verdict
Altra Experience Flow 3
Altra Torin 9
The Altra Torin 9 and Altra Experience Flow 3 are two daily trainers from the same brand, but the Experience Flow 3 is the stronger all-around option. Its low drop is easier to adapt to than the Torin's zero-drop platform, and its lighter weight, wider base, and gusseted tongue make it more stable and versatile for daily training. Get the Experience Flow 3 for the more capable everyday daily trainer. Stick with the Torin 9 only if you specifically want to stay with a full zero-drop platform.
