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.
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 Speed 2 combines ultralight and springy
PWRRUN PB 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.
