The Evolution
of Fast

Engineered with elite athletes and built for everyday runners, the Endorphin Collection features revolutionary SPEEDROLL Technology, which propels you forward with the feeling of continuous momentum.

The result? Faster speeds. Better times. And more good runs for all.

Race Day

With ultralight, springy PWRRUN PB cushioning and our signature S-curve carbon fiber plate, the EndorphinPRO uses SPEEDROLL Technology to blur the line between each stride so that running beyond race pace feels effortless, and personal bests come naturally. Simply put, it’s the fastest shoe we’ve ever built.

Speed Day

From tempo workouts to race day, the EndorphinSPEED combines a semi-rigid nylon plate with ultralight and springy PWRRUNPB cushioning. The resulting SPEEDROLL propels you forward and helps you get more out of every stride so that running faster feels easier.

Easy Day

The EndorphinSHIFT combines a lofty bed of PWRRUN cushioning with finely-tuned stability features to create a truly effortless ride. That’s SPEEDROLL at work, propelling you to faster, feel-good runs for every day of the week. So if it feels like the shoe is doing the work for you, it’s because it is.
