A Versatile Running Shoe That Can Handle Any Workout You Throw At It
The Saucony Endorphin Speed series has dominated the space as one of the most versatile and lightweight trainers you can find. The Endorphin Speed 4 continues this legacy with a few adjustments and upgrades to help push this shoe to its limits.
A familiar feeling of PWRRUN PB can be found underfoot, creating a soft but super-responsive experience that’s further enhanced with the addition of the new Super Responsive sockliner. Within this premium midsole cushioning is an updated winged nylon plate, creating torsional rigidity while allowing forefoot flexibility. All these features underfoot synergize with incorporated SPEEDROLL Technology to bring you an efficient stride with effortless speed.
Run with confidence with the secure-fitting, engineered zonal mesh upper, offering optimal breathability with minimal weight. The Endorphine Speed 4 upper uses an integrated tongue to increase comfort and create a better fit. Along the outsole, you’ll notice a distinct lattice configuration made from Saucony’s XT-900 carbon rubber. The combination of premium material and expert design gives this trainer enhanced durability and incredible traction on varied surfaces.
The Saucony Endorphin Speed has built a loyal fanbase over the years and there doesn’t seem to be any sign of that stopping soon.
Features & Benefits:
- PWRRUN PB foam cushioning offers an incredibly lightweight and responsive experience
- New Super Responsive Sockliner adds more bounce underfoot with additional supercritical foam
- A re-engineered winged nylon plate allows forefoot flexibility while maintaining torsional rigidity
- Engineered zonal mesh upper with integrated tongue creates a comfortable and secure fit
- SPEEDROLL Technology encourages smooth turnover and a propulsive experience
- XT-900 carbon rubber increases overall durability and enhances traction

My Race Day Runners
This is my second pair of the Endorphin Speed 4. In June 2025, I earned a Half Marathon PR wearing my first pair! I recently purchased a second pair, which I just wore in a Half Marathon Relay with my son. We placed 4th in our coed division. I love that that these shoes are lightweight while also being supportive.The plate allows me to really push off while going uphill. I am hard on shoes, in part due to an arthritic toe that causes me to strike harder on my left heel, so my first pair wore about a bit quickly. - I think I got a little over 100 miles on them before needing to retire them.This is less mileage than I am able to get on other runners.

Great every day running shoe
This is my go-to running shoe. Offers great support for those suffering from plantar. Had to size down though since this version had a bigger toe box.

Like a cloud
The Endorphin Speed 4 hugs the foot like a cloud providing a cushioned and springy run. Highly recommend for road running/regular run training especially for longer runs (over 6 miles).

What I need in stock!
Saucony has become my go to shoe! I love that the Speed 4 has a little more softness and bounce. I've now started using them as both my daily trainer as well as on speed days.

Must add to your quiver of shoes!
Marathon sports is the best. Great customer service, I had a question about shipping. Shipping was super fast. I was able to exchange for a different size, no hassle. These shoes are classic, great training and racing shoe. Breathable and has great push off.

Great running shoes! They’re fast and soft, but stable

My go-to shoe
This is my second time buying the Speed 4s, after also having multiple pairs of the 2s and 3s over the past couple of years. The 4s have been my favorite — great fit, fun colors, durable, and give me a smooth ride on the run. Only complaint on the last pair was that the Saucony logo started peeling off, but haven’t had that problem yet on these

Saucony speed 4 is elite!
My overall experience has been nothing amazing. I accidentally purchased a women’s size 10.5 and the size swap for a men’s 10.5 was simple and easy. The running sneaker itself is lightweight and durable. I cross train from running and weight training and it’s been heaven for my feet. I would recommend 10/10!

Fast nylon plated shoe
Have enjoyed running workouts and short races in these - definitely give some popat faster paces. Wouldn't recommend for anything over 10 miles as my feet started to get achy.

Not for wide feet
I’ve been looking for a new tempo training shoe and the internet loves these so wanted to try them. I found them extremely narrow in the forefoot, and they felt narrow underfoot during a track workout. I have a wide forefoot but typically wear regular width shoes anyway; by comparison these were much narrower than anything I’ve run in.

Great shoe; wears out fast
This is an excellent running shoe. Super lightweight, propulsive, can be worn for everyday miles as well as racing. They do wear out fast, though. With some outsole wear occurring within a few weeks of use.

bummer
my toes go numb in these, even sizing up.
