Effortless Feel Provides Effortless Comfort

The most noticeable thing about the Endorphin Pro 2 is the boldly designed upper. Racing checks and accented pops of color add to the overall fast look of the shoe.

Saucony draped the Endorphin Pro 2 in a single layer engineered mesh upper that keeps the shoe lightweight and breathable. The mesh works with Saucony’s unique FORMFIT technology to contour to the shape of your foot for a huggy, supportive feel.

“If socks could be carbon plated, they would be the Endorphin 2’s. I can’t get over how snug and comfy these are,” says one reviewer. “They feel instantly supportive in the arch and heels, and I feel like the footbed really contours to my foot.”

On top of the FORMFIT technology throughout the shoe, the Endorphin Pro 2 also uses an attached booty-like tongue to dial in on the snug fit. Since the tongue is attached, it eliminates uncomfortable rubbing or moving while you run, and it’s lined with silky smooth material.

“The tongue liner is so soft, I could comfortably wear these shoes without socks. The whole thing feels secure but not stifling,” says a reviewer.

Perhaps the biggest update, though, is the redesigned heel support. Saucony designers paid special attention to creating an engaged feel throughout the shoe, starting with the heel.

While it may seem simple, the additional padding at the heel collar makes a world of a difference when running at top speeds.

Reviewers instantly noticed the extra padding and the smooth, performance material that wraps around the heel collar.

“I’ve previously avoided Saucony shoes because they would always bother my heel,” says one reviewer. “The inner material on the heel in the updated Endorphins is super soft and smooth and has just the right amount of hugginess.”

Saucony S-Curve Supports Super Speed

The original Endorphin Pro made a splash as a competitive carbon fiber plated shoe when they first hit the market. The updated Endorphin Pro 2, and the entire Endorphin 2 series, homes in on the powerful S-Curve carbon fiber plate.

So how does the Endorphin Pro 2 make you faster? It’s all about the Speedroll.

Saucony engineered its unique Speedroll technology to capitalize on the body’s natural forward momentum while running and multiply it. The specialized shoe geometry creates a rolling, propulsive feel through a network of foams and plating systems for a nearly effortless run.

“The ride in these shoes felt engaged and propulsive. I didn’t feel like my foot was being forced forward or that the shoe didn’t accomodate my natural landing, but instead the shoe took my natural gait and made it feel rolling and efficient,” says one reviewer.

The S-Curve carbon fiber plate rests at the center of this speed sandwich and works with your natural stride to deliver the responsive snap you need to keep it rollin’.

One member of our review team smoked a bunch of her friends in a local Pub Run in the Endorphin Pro 2s recently, and she loved every second of it.

“I wore these to a pub run on a really hot day when I was already feeling tired. I was hoping they would give me a boost, and they definitely did! I started at the back of the pack and kept working my way up to the front without feeling like I was trying very hard,” she says. “Wearing the Endorphin Pro 2 felt like wielding a secret weapon!”

In addition to a springy feel in the midsole, the Endorphin Pro 2 is equipped with a reinforced, XT-900 outsole.

Designers strategically placed the outsole material at high-abrasion zones along the bottom of the shoe to provide traction and durability where you need it, while eliminating added weight and bulk.

Endorphin Pro 2 vs Endorphin Pro

A comparison of the original Saucony Endorphin Pro and the Endorphin Pro 2

If you were a fan of the original Endorphin Pro, you won’t notice a big difference in the Endorphin Pro 2 update.

If you’re just jumping on the Endorphin train now, don’t worry, you haven’t missed out.

The biggest change in the Endorphin Pro 2 is the enhanced fit through the heel and upper thanks to additional heel collar cushioning and a new, no-slip lacing system.

Our reviewers were especially keen on this update, as it helps to accommodate a wide range of foot shapes without compromising on the speedy feel.

“It hugs my foot perfectly,” says one reviewer. “I’m also happy that this shoe has an extra eyelet to make the fit more secure. It keeps my heel from shifting around when I pick up the pace.”

The updated engineered mesh upper packs all the benefits of a single-layer upper while still feeling just as durable and secure as before.

This upgrade maximizes breathability throughout the shoe, adding to the overall ultralight feeling.

We can’t talk about the upper without talking about the striking graphics. The Endorphin Pro 2 is ready to roll on race day with bold racing checks and colored accents. You won’t be able to tell if you’re gearing up for the Indy 500 or your local 5K (as if there’s a difference).

As one reviewer put it, “I’m impressed, obsessed and can’t wait for my next run in them. They look badass and feel badass.”

Final Thoughts

The Saucony Endorphin Pro 2 packs next-level speed into a lightweight package.

Powered by Saucony’s S-curve carbon fiber plate and poppy PWRUN PB foam, the Endorphin Pro 2 delivers a smooth, responsive ride over roads and tracks.

Unique Speedroll technology integrates a beveled geometry throughout the shoe for an overall rolling feeling as you run. Combined with the carbon fiber plate and springy foam, the Endorphin Pro 2 promises powerful transitions and incredible energy return.

In addition to the fast tech underfoot, Saucony’s biggest update to the Endorphin Pro 2 is seen in the upper.

Between the soft yet secure feel of added heel collar padding and the single-layer engineered mesh upper, the Endorphin Pro 2 is even more breathable and lightweight than ever.

Our reviewers recommend the Endorphin Pro 2s for your fastest efforts.

“They are the perfect shoe for your next big race, from a 5K to a marathon, and they will help you float through miles on long, tough speed workouts too,” says one reviewer.

So whether you’re hitting the pavement for the first time post-pandemic or are gearing up to smash a PR, make sure you do it in the Saucony Endorphin Pro 2.
