For those who are seeking relationships that go the distance, the Saucony Endorphin Speed 5 men's performance running shoes are here to fill the role. Designed as race-day shoes, they are quickly proven themselves 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 PWWRUN PB foam, those cushioned running shoes provide the perfect balance of support, rebound and forgiveness.
