The Saucony Endorphin Speed series has been a true game-changer in the running world. And no, we’re not exaggerating. It proved that a plated shoe doesn't have to be an uncomfortable, short-distance "racer," but can also be an incredibly fun partner for your everyday speed sessions. Whether you’re chasing a half-marathon PR or looking for a shoe to propel you through a tough tempo run, the Speed series delivers. With every new generation, Saucony fine-tunes the stiffness of the nylon plate, the midsole geometry, and the breathability of the upper. Let’s take a look at how the latest generations — the Saucony Endorphin Speed 3, 4, and 5.
Saucony Endorphin Speed: Core Features
You’ll fall in love with the Endorphin Speed because of its versatility. It’s a shoe that blurs the lines between training and racing. What do all generations have in common?
- PWRRUN PB Foam: High-quality PEBA-based cushioning that is extremely lightweight and returns energywith every stride.
- Nylon Plate: Unlike stiff carbon, nylon is more flexible and forgiving, allowing you to wear the shoe for speed workouts without excessive tendon fatigue.
- SPEEDROLL Technology: This signature rocker geometry propels you into the next step and encourages a more active toe-off. It relies on increased cushioning and a stiffer forefoot, meaning the shoe is highly responsive, allowing you to run faster with less effort.
- A Partner for Both Racing and Training: You can rely on it for fast races, tempo runs, or dynamic intervals. It will support you over both short and long distances. On the other hand, it doesn't quite get along with slow recovery runs, where it can feel a bit too "lively" and unstable—therefore, it’s not generally recommended for absolute beginners.
Saucony Endorphin Speed 5 – The Speedster That Drives You Forward
The Endorphin Speed 5 brings a fierceness you’ll feel the moment you lace them up. This shoe won't let you down — whether it's race day or a grueling workout. What’s new?
- Upgraded Nylon Plate: The redesigned "winged" nylon plate is stiffer in key zones for an even more aggressive toe-off, while still maintaining flexibility and pop during transition.
- Newly Optimized PWRRUN PB: In its fifth generation, the foam is slightly lighter, softer, and offers higher energy return, significantly saving your legs in the final kilometers of a race or training session.
- Lightweight and Refined Upper: The ultra-thin, breathable mesh with minimal seams ensures you barely feel the shoe on your foot. The tongue is gusseted to stay put even at high speeds, and heel padding adds an extra layer of comfort. You can focus entirely on your pace.
- More Aggressive SPEEDROLL Technology: The rocker geometry is tuned to encourage a midfoot-to-forefoot strike.
- New SRS Insole: First introduced in the fourth generation, the SRS (Super Responsive Sockliner) ensures instant responsiveness, enhances comfort, and boosts running efficiency by returning energy from the very first contact with your foot.
Who is the Saucony Endorphin Speed 5 for?
- Ambitious runners looking for one shoe for fast training and road races from 5K to a full marathon.
- Those who expect maximum dynamics and the feeling of being "snapped" forward.
- Runners with established running form who appreciate lightness and aggressive energy return.
- Those who find carbon plates too stiff and prefer the flexibility of nylon.

Saucony Endorphin Speed 4 – The Balanced All-Round Partner
The fourth generation brought a solid dose of stability without losing its legendary speed. It is arguably the most versatile shoe in the entire series. Let’s take a closer look.
- The Heart of the Endorphin Series: Even in the fourth generation, you can rely on the top-tier PWRRUN PB cushioning, a dynamic nylon plate, and SPEEDROLL technology, which helps you achieve a smooth and fast transition from heel to toe.
- The New SRS Insole: This was a total game-changer for the fourth generation. The SRS (Super Responsive Sockliner) works in tandem with the PWRRUN PB foam. As a result, the shoe reacts instantly, returning energy even before the main cushioning layer and nylon plate are fully engaged.
- Zonal Upper Construction: It combines a secure heel lockdown with a highly breathable toe box, making it an excellent choice for long tempo runs.
- A Partner for Everyday Speed: This model is a true workhorse. It’s capable of handling a fast race, but thanks to its durability and comfort, it can also withstand a high volume of spirited training miles.
Who is the Saucony Endorphin Speed 4 for? It is perfect for runners looking for the ultimate balance between stability and speed, and who want a reliable partner for both fast races and high-volume tempo training.

Saucony Endorphin Speed 3 – The Classic That Started the Boom
The Speed 3 is the model that truly put the series on the map for the broader running community. The fact that it remains a highly sought-after option even today proves its lasting appeal. Why?
- More Flexible Nylon Plate: The Speed 3 features an S-shaped plate that is slightly more compliant than in the newer models, making it the most comfortable shoe in the lineup for longer runs.
- Plusher Padding: You’ll find more material in the heel and tongue compared to its more "race-oriented" successors, which enhances step-in comfort.
- Softer Underfoot Feel: The PWRRUN PB foam feels a bit softer here — something you’ll appreciate if you’re not a fan of a stiff or overly aggressive toe-off.
- Time-Tested Upper Design: This was a bet on the classics. A simple, functional upper that fits most foot types comfortably.
Who is the Saucony Endorphin Speed 3 for? It’s ideal for runners who are just entering the world of plated running shoes and want to experience the benefits of modern super-foams in a more comfortable, softer package that is more forgiving of minor flaws in running technique.
