The Saucony Endorphin Speed 6 is a nylon-plated speed trainer for workouts and uptempo daily miles. New PWRRUN PBX foam brings more cushioning and a lighter feel than the Speed 5, with 2mm extra stack underfoot and a redesigned nylon plate for a propulsive, smooth roll through toe-off.
A lightweight engineered mesh upper keeps the foot locked in as the pace picks up, and XT-900 rubber adds grip and durability. With an 8mm drop and SPEEDROLL geometry, it's a versatile neutral shoe for tempo runs, intervals and everyday training.
