The Endorphin Speed 2 features ultralight, perfectly balanced, and flexible PWRRUN PB foam. It shines for everything from fast runs to long distances, workouts, and race days.

SPEEDROLL technology propels you forward with a feeling of continuous momentum. The two key variables are elevated cushioning and a stiff forefoot, which result in an instantly responsive ride, so you can run faster, not harder. The Endorphin Speed 2 combines ultralight, springy PWRRUN PB cushioning with a semi-rigid full-length nylon plate that is more flexible than carbon fiber. This results in a powerful SPEEDROLL effect that works for both speed workouts and race day. We worked with our athletes to refine the heel shape and provide a locked-in feel for every mile.
