The Endorphin Pro has always stood out in the carbon racer category for feeling predictable and accessible rather than demanding and twitchy. The Endorphin Pro 5 keeps that identity intact while sharpening every performance detail that matters on race day.

The dual-layer midsole pairs supercritical PWRRUN HG on top — now extended further up the sidewalls for improved inherent stability — with a PWRRUN PB base layer featuring a strategic underfoot cutout that shaves grams without sacrificing cushioning where it counts. The full-length carbon fiber plate gets a meaningful update with a slotted forefoot design borrowed from the Endorphin Elite, allowing more natural foot flex while a more pronounced rocker profile drives snappier transitions and better propulsion through the toe-off.

Underfoot, Saucony upgraded to PWRTRAC rubber for an outsole that outlasts its predecessor and grips more confidently on wet road surfaces — a practical improvement for anyone who has ever raced through a rainy morning. The lightweight recycled engineered mesh upper is streamlined and breathable, delivering a secure lockdown without the stiffness that can make some race shoes feel unforgiving over longer distances.

Whether you're targeting a 5K PR or digging deep in the final miles of a marathon, the Endorphin Pro 5 gives you the propulsion of a serious carbon racer with enough forgiveness to run your best from start line to finish tape.

MIDSOLE

• PWRRUN HG superfoam forms a full-length top layer that's more generous than before. It offers firmer response, added sidewalls, and high energy return.
• PWRRUN PB superfoam bottom layer is a PEBA formulation for lightweight, maximal cushioning and rebound.
• All-new carbon fiber plate is a more aggressive, full-length design with better foam integration for enhanced propulsion and smoother transitions.
• SPEEDROLL technology promotes forward momentum and efficient rolling motion with a more pronounced toe rocker curve.
• Super Responsive Sockliner (SRS) adds a step-in layer of molded supercritical cushioning.

OUTSOLE

• PWRTRAC rubber provides a thin layer of premium rubber for 15% better traction on wet surfaces and greater resistance to abrasion.
• Central cutout reduces weight while preserving the stack height and plush feel.

UPPER

• Recycled engineered mesh is breathable, lightweight, and sustainable for a secure and streamlined race fit with excellent ventilation.
