An Altra shoe with drop? Still true! The Experience Flow 2 continues to challenge expectations while staying true to Altra's roots. Featuring the brand’s signature FootShape™ fit, it gives your toes room to splay and your stride space to breathe—now paired with a subtle 4mm heel-to-toe drop for those craving a touch of forward roll. It's a road runner built for effortless movement and all-day comfort. Previously known as the AltraFWD Experience, the Flow 2 brings a familiar, fluid ride with thoughtful updates. The upper now features an airy, dual-tone engineered mesh that keeps things cool and breathable through warm-weather runs. Underfoot, the rocker-shaped geometrypairs beautifully with lightweight, responsive midsole foam to encourage a smooth toe-off and quick transitions on every stride. Whether you're logging base miles, keeping pace with your crew, or just heading out to clear your head, this shoe delivers a consistently enjoyable ride. Experience the evolution—natural comfort, now with just a little flow.
