A firmer compression-molded foam midsole and aggressive rocker shape deliver an energetic rolling sensation that makes the Altra Experience Flow an exciting neutral trainer for daily runs and workouts. In our Altra Experience Flow review, our testers praised the unexpected liveliness of the firm, yet lightweight cushioning. “Running in the Experience Flow is a lot of fun,” says Tony. “The shoes feel very light on my feet and the foam has a very responsive feel–more than I was expecting, being that it’s on the firmer side. When I wore these for the first time, I was happy the entire run.” The Experience Flow bridges the gap to zero-drop with a low, 4 mm offset and effortless ride.

Details: Upper: The Experience Flow features a Standard FootShape™ Fit, which falls in the middle of Altra’s three different options. “Great wiggle room in the toe box and a glove-like fit in the midfoot,” says Travis in our Altra Experience Flow review. Midsole: With a 4 mm drop, the Flow’s lightweight compression molded midsole gives you a responsive feel in combination with a rocker shape to gently roll you forward into your next stride.
