The Experience Flow (formerly known as the AltraFWD Experience) is all about a ride that’s smooth, effortless, and efficient. Glide through daily workouts, crush long training runs, and smile through miles with the run club crew. Featuring an updated two-color engineered mesh for greater breathability. A low, 4 mm drop complements the shoe’s rocker shape geometry, for an efficient toe-off and a smooth, quick roll through your stride. It’s got the same lightweight and responsive compression-molded midsole foam for performance. With Altra’s signature FootShape fit, you get a roomy toe box and a secure midfoot, so you can move the way you were designed to. Get into the flow and experience an effortless run!
