Saucony Endorphin Pro 3 Offers More Cushion with Less Weight

A pair of Saucony Endorphin Pro 3.

The Saucony Endorphin Pro 3 manages to pack in more cushioning while reducing the overall weight, so you don’t have to sacrifice comfort for performance.

The latest version of the Saucony Endorphin Pro features more PWRRUN PB foam in the midsole than ever before - 4 millimeters more to be exact. Saucony’s PWRRUN PB midsole foam is light and springy, perfect for powering through to a new personal best.

“These shoes feel like magic for a speed workout. They’re so propulsive, and really fun to run in. They make me feel like I’m gliding, and definitely help me to pick up the pace. The way that the foam rebounds makes it a perfect race shoe,” Kate says.

“These shoes are super comfortable with a great bounce. I can definitely feel the difference from the carbon plate with turnover and the shoe helping to push me forward on the run,” Jasmine says.

A full-length carbon-fiber plate sits inside the midsole and serves as this shoe’s not-so-secret weapon. The carbon-fiber plate helps the foam compress upon landings and snap back during take-offs, using your own energy to propel you forward.

“These shoes are magical. Somehow they are as comfortable as the maximally cushioned shoes on the market, light as the most minimalist shoes, and still give a noticeable bouncy kick to your stride,” Alex says.

Saucony uses their SPEEDROLL technology in the Saucony Endorphin Pro 3, the same geometry used in the previous two versions to help roll you forward during transitions. That, combined with the carbon-fiber plate and the light, springy foam, creates an effortlessly smooth ride that will keep you moving for miles.

“The shape and softness of the foam cradles my foot in a really cushy, supportive way. With each step the foam feels like it’s rebounding and sending me forward. For many shoes, the foam doesn’t really come alive until you start running, but with the Endorphin Pro 3, it feels lively from the moment you put the shoe on your foot,” Kate says.

Airy Mesh Upper Brings Style to the Start Line

Not only will you feel speedy in the Saucony Endorphin Pro 3, you’ll look the part too. The latest version of the Endorphin Pro offers a lightweight, breathable mesh upper that subtly shimmers.

Reviewers enjoyed the fit, feel and flash of the Saucony Endorphin Pro 3.

“The upper is super flashy – perfect for race day, and clearly designed to be light, with big, open mesh for ventilation and cut-outs along the top of the foot for extra breathability. The thin, suede tongue is soft and comfortable without adding anything unnecessary,” Kate says.

Saucony used their FORMFIT design in the upper to support the contours of your feet while offering breathability and flexibility. Reviewers with all different foot shapes found their perfect fit in the Endorphin Pro 3.

“I really love the streamlined mesh upper. It’s everything you want in a race shoe: super airy with a good balance of structure, contour and comfort. The tongue feels great, wrapping around the top of my foot with zero discomfort or hot spots,” Nate says.

“I can’t say enough good things about the mesh upper. I have a narrow foot and it felt like a glove when lacing up,” Jasmine says.
