Endorphin Speed 6
The Endorphin Speed 6 bridges fast training and racing. New beaded PEBA-based PWRRUN PBX cushioning adds foam while reducing weight versus Speed 5. A reshaped nylon plate and SPEEDROLL promote smoother, more propulsive transitions, while lightweight breathable mesh holds the foot as pace rises. It is built for tempo efforts, intervals and track workouts.
