Saucony Endorphin Speed 5: Lightweight Power for Every Pace

From daily miles to tempo runs and everything in between, the Saucony Endorphin Speed 5 is your do-it-all performance trainer — responsive, nimble, and designed to keep you moving fast. Now in its fifth iteration, this fan-favorite super trainer continues to impress with updated geometry, a re-engineered plate, and finely tuned cushioning, making it one of the most versatile shoes in the performance running space.

At the core of the Speed 5 is PWRRUN PB, Saucony’s spring-loaded PEBA-based superfoam. It’s sculpted for reduced weight and shaped for smooth, fast transitions. Embedded within is a redesigned nylon plate that now features a more flexible, torsion-friendly shape — no lateral wing, and a new medial wing for improved stability and smoother midfoot transitions.

This combo of foam and plate is supported by SPEEDROLL™ geometry, which encourages an effortless forward momentum — helping you run quicker without trying harder. Underfoot, the XT-900 outsole offers durable traction and improved heel coverage, while a full-length flex groove helps maintain adaptability and responsiveness on varied efforts.

Up top, the single-layer engineered hex mesh upper delivers breathable comfort with a sleek, performance-driven look. A 3D heel counter adds rearfoot stability, and the Super Responsive Sockliner (SRS) provides that plush, bouncy feel the moment you step in.

Whether you’re hitting long runs, sharpening speed, or just want a fun, fast ride for daily training, the Endorphin Speed 5 offers race-ready energy in an everyday package.
