Shoe Specifications

Designed as an up-tempo shoe, it’s quickly proven itself as much more, equally capable during long, moderate training sessions and sprints to the finish.

The Endorphin Speed 5 is built to go fast and feel smooth—whether you're pushing the pace on track night with friends or chasing a PR . A newly designed nylon plate and responsive PWRRUN PB cushioning come together for snappy transitions and a fast ride. This is speed you can count on.

Product Highlights

Snappy Ride – A full-length semi-rigid nylon plate between two layers of responsive PWRRUN foam, giving you a perfect balance of propulsion and cushioning for every stride.
Optimized Outsole – Reconfigured outsole with expanded coverage in the heel for greater durability during your quickest strides.
Natural Flow – Full-length groove enhances your gait cycle, giving you a smoother transition from foot strike to push-off.
