Saucony says

We're all seeking relationships that go the distance. The Endorphin Speed 4 running shoe is here to fill the role. Designed as a race-day shoe, it's quickly proven itself much more, equally capable during long, moderate training sessions and sprints to the finish. Thanks to the "just right" combination of winged nylon-plate, SPEEDROLL technology and PWRRUN PB foam, this cushioned running shoe provides the perfect balance of support, rebound and forgiveness.
