This shoe runs a little short. We recommend going up a half-size from your normal running shoe. Speedwork? Long run? Racing? You can do it all in the Saucony Endorphin Speed 3. Saucony updated this shoe to make it faster than ever. Designers changed the geometry of the shoe, making it a bit wider, to give you a smoother ride as you run. Then they added more of their ultra light PWRRUN PB foam, increasing the stack height and making it more cushioned and bouncy, so you can run faster for longer. Saucony’s SPEEDROLL technology propels you forward step after step, while a new S-curve winged nylon plate returns your energy throughout your run so your legs feel fresh. It supports your foot throughout your stride, so you can push your pace. A new upper gives you a better fit throughout your entire foot, while staying lightweight and breathable. In our Saucony Endorphin Speed 3 review, one tester noted, “The upper is simply perfect. My feet feel locked down with plenty of breathability and just that touch of extra padding that’s nice for longer miles. There’s enough room for my wider feet to stretch out as needed.” Plus, there is a XT-900 rubber outsole to let you grip the road as you run. Fast and lightweight, yet durable enough for everyday training, the Saucony Endorphin Speed 3 will help you run to your next personal best.
