Endorphin Speed 5
The Endorphin Speed 5 is a speed trainer for track sessions, tempo runs and racing. A full-length semi-rigid nylon plate sits between two responsive PWRRUN PB layers, working with SPEEDROLL for snappy, smooth transitions. Lightweight engineered mesh improves fast-run comfort, while expanded heel coverage and a full-length outsole groove add durability and support a more continuous gait from foot strike to push-off.
