Saucony Endorphin Speed 4 Initial Thoughts

I usually wear the Saucony Endorphin Speed 2 and 3 for most of my interval training so I was really excited to see what the latest version of this shoe looked like and felt like. I had high hopes for this incredible shoe that I have worn for the last few years of training.

The first thing I noticed was how light it felt. While it isn’t as light as the Endorphin Pros, it really is super lightweight. The next thing I noticed was the cushioned tongue. I’m always a big fan of these so that you can tie your shoe tight and not have any issues with pressure on the front of your foot, something that adds to overall comfort. Lastly, the thing I noticed was the shape of the heel part of the sole. It looks way more aerodynamic than the previous version.

I first wore these on an 6 mile interval effort on the treadmill and was impressed with how they felt when I needed to put the hammer down. All in all, a great first impression!

Saucony Endorphin Speed 4 Shoe Sole

The Saucony Endorphin Speed 4 features a re-engineered sole designed to deliver optimal performance for runners. Its PWRRUN PB foam midsole offers lightweight cushioning and exceptional energy return, making it ideal for fast-paced runs and long distances.

When looking at this sole compared to the Saucony Endorphin Speed 3, you notice how different they are, specifically almost the v shaped gap in the heel of the sole. You can see this in the pictures below.

The SpeedRoll technology incorporated into the sole promotes a smooth forward motion, allowing runners to maintain momentum with less effort. Additionally, the durable rubber outsole provides superior traction and grip on various surfaces, ensuring stability and control during high-speed sprints. Designed for efficiency, the Endorphin Speed 4’s sole enhances comfort and speed, perfect for runners looking to improve their performance.

Saucony.com states “Designed as a race-day shoe, it’s quickly proven itself much more, equally capable during long, moderate training sessions and sprints to the finish. Thanks to the “just right” combination of winged nylon-plate, SPEEDROLL technology and PWRRUN PB foam, this cushioned running shoe provides the perfect balance of support, rebound and forgiveness.“

The sole still looks great after a few runs. I will say that I still wear my Endorphin Speed 2’s and 3’s on shorter effort, which is a testament to the durability of the shoe.

Saucony Endorphin Speed 4 Shoe Upper

The upper of the Endorphin Speed 4 continues to have engineered mesh, making it a shoe that performs and breathes well all while being lightweight.

As I mentioned, the shoe features an advanced upper designed for superior comfort and breathability. Constructed with a lightweight, engineered mesh, the upper provides optimal airflow, keeping feet cool during long runs. The FORMFIT design adapts to the shape of the foot, delivering a sock-like fit that enhances support and reduces pressure points. The reinforced overlays in key areas offer added support and durability without sacrificing flexibility.

One of the things I like best is the padded heel collar and tongue improve comfort, all while preventing slippage. With a focus on both performance and comfort, the upper of the Endorphin Speed 4 ensures a secure, responsive fit that keeps runners moving efficiently.
