Podium-worthy. On and off the course. Building on an award-winning year, the Endorphin Speed 2 is back with its just-right combo of ultralight PWRRUN PB cushioning and a flexible nylon plate. It shines for both speed work and long miles, workouts and race day. Finally, a shoe that works as hard as you do.
