The Endorphin Speed 4 was designed as a race-day shoe, but it’s quickly proven itself to be much more. Take it for a run and you'll find it to be equally capable during long, moderate training sessions and sprints to the finish. Thanks to the “just right” combination of a winged nylon-plate, SPEEDROLL technology, and PWWRUN PB foam, this cushioned running shoe provides the perfect balance of support, rebound and forgiveness.
