Altra Experience Flow ST

The Altra Experience Flow ST is Altra’s light-stability daily trainer built for runners who want guidance without the clunky feel of a traditional support shoe. Formerly known as the Experience Form, it blends a smooth rocker shape with a low-drop platform to keep your stride rolling efficiently through easy miles, steady runs, and walk-to-run days. Underfoot, Altra’s EGO P35 foam aims for that sweet spot of protection and lively turnover, while a broader, more stable base helps you stay centered when fatigue sets in.
