Saucony Endorphin Speed 3

The Endorphin Speed 3 is an incredibly popular choice for marathon and half-marathon training, offering a perfect blend of cushioning and bounce. It features a full-length PWRRUN PB midsole, providing exceptional energy return without the rigidity of a carbon plate.

No, unlike its sibling the Endorphin Pro, the Speed 3 utilizes a semi-rigid nylon plate instead of a carbon-fiber plate. This gives the shoe a more forgiving ride, making it versatile enough for both daily training and fast tempo runs.

The shoe features an updated engineered mesh upper that provides a secure, foot-hugging fit around the midfoot while keeping the toe box relatively spacious. It runs relatively true to size for most runners.

The Saucony Endorphin Speed 3 features an 8mm heel-to-toe drop. This mid-level drop is standard for Saucony racing shoes, allowing for a natural rolling motion thanks to their SpeedRoll geometry.
