The Endorphin Collection

Unbelievably fast. Endless potential.

Effortless performance.

Each Endorphin is uniquely designed to help you get more out of race day, speed day, and every day.

We’ve got speed down to a science.

The Endorphin Collection is powered by SPEEDROLL Technology, an advanced form of footwear geometry based on variables like foam, propulsive plates, stack heights, and midsole shape. Each style is meticulously engineered to give you an effortless, always-forward motion that makes every speed feel like top speed. It’s all about amplifying your stride and unlocking your own feeling of fast.

Level up with our PWRRUN Cushioning Series.

Smoother, locked-in feel with FORMFIT.

The enhanced fit of these styles gives a personalized, locked-in feel that minimizes slipping in-shoe, making every stride matter more. And with all-encompassing comfort, you can break PBs while hardly breaking a sweat.
