Purchased NWOB. They don’t fit me. My trail shoes are Altra Lone Peak size 9.5 and I thought I’d try these for road running. The toe box is too narrow for me, after wearing barefoot shoes for so long. I sized up to a 10 and those fit perfect. So if you’re trying these for the first time and NEED a wide toe box - maybe make sure these are a 1/2 size up from what you normally run in. 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 4mm 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!
