Saucony’s Endorphin lineup has revolutionized the running shoe game, especially for athletes looking for speed and performance. Two of the most talked-about models in this line are the Endorphin Speed and the Endorphin Pro. While they share similar technology, they are designed for different purposes. So, which one is right for you?
Let’s break down the differences in design, performance, comfort, and use case to help you make the best decision.
Key Similarities Between the Endorphin Speed and Pro
Before diving into what sets them apart, it’s helpful to understand what they have in common:
- PWRRUN PB Midsole Foam: Both models use Saucony’s PEBA-based foam that offers an exceptionally lightweight and responsive ride.
- SPEEDROLL Technology: This geometry is designed to create a rolling-forward sensation that reduces effort and encourages faster turnover.
- Engineered Mesh Uppers: Breathable and lightweight uppers that hug the foot without adding bulk.
These shared features create a fast, cushioned ride in both shoes—but the devil is in the details.

- More Forgiving Ride: Great for tempo runs, long runs, and even race day.
- Durability: Built to last through hundreds of miles of hard training.
- Weight: Around 8.1 oz (men’s size 9)
Best For:

Comfort and Fit Comparison
