Head to head: Comparing the Saucony Endorphin Speed 4 vs Saucony Endorphin Pro 4

When we talk about fast shoes, Saucony is always in the conversation, and with two models like the Endorphin Speed 4 and the Endorphin Pro 4, the choice becomes even more interesting. Both share a common heritage and many of the brand's innovations, but are designed for different runner profiles. While the Speed 4 is all about versatility, the Pro 4 is the choice for those looking for pure speed in competition. If you've ever wondered which of these two is for you, here we break down their main differences and help you choose.

Saucony Endorphin Speed 4: versatility for all terrains

The Saucony Endorphin Speed 4 is an all-around running shoes. Ideal for both daily workouts and fast runs, it is an outstanding option for runners looking for a mixed model without the need to accumulate different pairs in the closet. Its secret lies in the combination of PWRRUN PB, a lightweight and reactive foam that propels you smoothly, along with a flexible nylon plate that adds an extra touch of reactivity without the demands of a carbon plate.

Weighing in at 233 grams in the men's version, the 4 Speed presents itself as a lightweight shoe but with enough structure to provide comfort over long distances. Its 8 mmdrop ensures a smooth transition, making it an accessible option for runners of different levels, from beginners to experienced runners.

The upper is another strong point of this shoe. Designed with a breathable and lightweight mesh, it ensures constant ventilation during longer runs. In addition, it fits comfortably and securely, providing confidence with every stride.

The Saucony Endorphin Speed 4 is the all-terrain shoe that can take you from quality training to the starting line of a half marathon.

Saucony Endorphin Pro 4: built for speed

If the Endorphin Speed 4 is the workhorse, the Endorphin Pro 4 is the Ferrari of the range. Designed specifically for competition, the Pro 4 is not a shoe for every day, but for those moments when you need to squeeze every second out of your run. Here, the protagonist is the carbon plate, which runs the entire length of the shoe and, together with the SpeedRoll geometry, provides an incomparable feeling of propulsion and speed.

The midsole combines two of Saucony's most advanced compounds: PWRRUN HG and PWRRUN PB, a duo that offers explosive reactivity, especially in the most demanding moments of the race. The result is a shoe that not only responds well at fast paces, but practically propels you forward.

With a 395 heel and 315 forefoot profile, the Pro 4 has an 8mmdrop that, like its smaller sibling, offers a smooth transition. However, the key difference is in the stiffness of the carbon plate, which demands more technique and strength from the runner. This is not a model for everyone: if you are not used to fast paces, you may find the Pro 4 more demanding than you expected.

The upper also follows the shoe's lightweight and minimalist philosophy. With a sock-like fit thanks to its stretch knit tongue, it fits the foot like a second skin. Everything is designed to maximize running performance, from breathability to the snug fit that keeps the foot in place at high speed.

Running sensations

Endorphin Speed 4

When you put on the Endorphin Speed 4 Speed, you immediately feel its versatile nature. The nylon plate provides just the right amount of reactivity without being aggressive, allowing the shoe to perform efficiently and comfortably on both long runs and fast runs. It is not a shoe that "forces" you to go fast, but it accompanies you in whatever you need.

At lighter paces, the Speed 4 maintains its lightweight cushioning and signature comfort, while on speed workouts or quality days, the shoe activates and responds fluidly, making keeping up with demanding paces no problem.

Saucony Endorphin Pro 4

The Pro 4 is another story. From the first step, the stiff carbon plate reminds you that this is not a shoe to relax in. If you're looking for speed and have the right technique, the Pro 4 rewards you with propulsion that seems to push you forward with every stride. It's not a shoe for a casual runner, but for those who are willing to take their performance to the next level.

Its cushioning is also different. While it is present and offers comfort, it doesn't have the same soft feel as the Speed 4. Here everything is optimized for speed and efficiency. Every impact becomes a rebound, an opportunity to move faster. However, if you're not ready for high paces or if you're looking for a comfortable shoe for long, leisurely workouts, the Pro 4 won't be your best ally.

Who each model is for

Saucony Endorphin Speed 4

The Saucony Endorphin Speed 4 is ideal for runners looking for a versatile shoe, capable of accompanying them in both fast workouts and races. If you don't want to mess around with multiple pairs of shoes and prefer a one-size-fits-all option, the Endorphin Speed 4 Speed is perfect for you. In addition, its flexible nylon plate makes it an excellent choice for runners who are not yet ready for the demands of a carbon plate or for those who prefer a mixed shoe, valid for both racing and training.

It is a shoe recommended for runners of moderate to fast pace, who are looking to combine comfort and reactivity in their daily training or competitions.

Saucony Endorphin Pro 4

On the other hand, the Endorphin Pro 4 is a shoe for experienced runners, with good running technique and who need an exclusive tool for competition days or high intensity workouts. If you're looking to squeeze every last second out of a marathon or half marathon, the Pro 4 is the shoe for you.

Recommended for runners who run at fast paces, who are looking for an extremely reactive shoe and who don't stop in their quest to improve their personal best times.

Speed or Pro?

Pitting the Saucony Endorphin Speed 4 and the Saucony Endorphin Pro 4 isn't a question of which is better, it's a question of which is better for you. If you're looking for versatility, a shoe that will serve you for training and racing alike, the Speed 4 is the right choice. If, on the other hand, you're a competitive runner who needs maximum propulsion and reactivity for those race days, the Pro 4 is the one to choose.

Both shoes share Sauconys DNA, but offer different experiences. The Speed 4 is an all-rounder, while the Pro 4 is the speed queen. Whichever you choose, both will help you fly through every stride.
