Feel-good cushioning and propulsive speed make every run feel better in the Saucony Endorphin Shift 3. When you first lace up the Endorphin Shift 3, you'll love how the FORMFIT design hugs every part of your foot for a personalized fit and feel. The upper is made with lightweight and breathable mesh that feels like nothing's there. It is paired with a streamlined heel clip that supports the back of your foot, so you'll feel nimble and light on your feet. The Endorphin Shift 3 is stacked with a taller bed of Saucony's PWRRUN cushioning and a PWRRUN+ sockliner for extra comfort over long miles or long weekends on your feet. To elevate your stride and propel you forward effortlessly, Saucony used their SPEEDROLL Technology and a new torsional heel groove to give you a smooth and snappy transition from heel to forefoot. Finished off with an XT-900 rubber outsole for grip and durability, this shoe can keep up with you whether you're training for a marathon or doing speed work. With high cushioning and a midsole geometry that works hard so you don't have to, watch your best runs come to life with the Saucony Endorphin Shift 3.
