Saucony Endorphin Speed 2

Up on the podium. On any track. Much like its award-winning predecessor, the Endorphin Speed 2 offers the perfect combination of ultra-lightweight PWRRUN PB cushioning and a flexible nylon plate. It impresses with its performance during tempo units and long runs, in training and on race day. Finally, a shoe that works as hard as you do. GOOD TO KNOW. - SPEEDROLL technology propels you forward with constant forward momentum. The two core variables are increased cushioning and a stiffened forefoot, which allows for direct reactivity when you run, so you can run faster, not harder. - The Endorphin Speed 2 combines ultra-light, springy PWRRUN PB cushioning with a long, semi-rigid nylon plate that's more flexible than carbon fiber. The result is the SPEEDROLL effect that gives powerful energy in training and racing. - We've worked with our athletes to fine-tune the heel shape and fit to keep the shoe secure and snug mile after mile. - This style incorporates recycled materials.
