Endorphin Speed 2

Podium-worthy. On and off the course.
Building on an award-winning year, the Endorphin Speed2 is back with its just-right combo of ultralight PWRRUNPB 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.

Rolling in speed
SPEEDROLL Technology propels you forward with the feeling of continuous momentum. Its two core variables are elevated cushioning and a stiff forefoot, which together result in an instantly responsive ride so you can run faster, not harder.

Versatile energy return
The Endorphin Speed2 combines ultralight and springy PWRRUNPB cushioning with a full-length, semi-rigid nylon plate that’s more flexible than carbon fiber, resulting in a powerful SPEEDROLL effect that works for both speed workouts and races.

Superior fit
We worked with our athletes to fine-tune the heel shape and fit for a locked-in feeling, mile after mile.

Good for the earth
