Selling a BRAND NEW pair of Saucony Endorphin Speed 4 in Mens size 11.5 in the "Cloud" colorway. I do not still have the original box, but the shoes have never been worn. 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. Offset: 8 mm Stack Height: 36 mm heel/28 mm forefoot Weight: 8.2 oz (233g)
