All About the Saucony Endorphin Speed 5

If you're serious about getting faster or just love the feeling of a smooth, responsive run, the Saucony Endorphin Speed 5 is a performance running shoe that should be on your radar and in your checkout basket. Whether you’re hitting the pavement with friends or pushing yourself through a tough tempo session, this road running shoe is made to keep you moving forward with the help from its awesome features. This shoe from the Endorphin sneaker range keeps everything runners loved about previous versions with a lightweight feel, cushioning, and snappy ride, but adds a few updates for even better performance.

Below, we’re breaking down all the tech that makes the Speed 5 such a standout Saucony running shoe.

SPEEDROLL Geometry

Let’s start with the SPEEDROLL design that’s Saucony’s signature rocker technology, and it’s a big part of what gives this shoe its fast, effortless feel. It uses an advanced underfoot geometry that encourages a continuous rolling motion from heel to toe, helping you keep your momentum - reducing the energy it takes to push forward. Whether you're doing a lazy lap around the block or trying to smash a PB at the track, this shoe helps you keep the pace up without overworking your legs.

PWRRUN PB Foam

The midsole is made from PWRRUN PB, our top-tier cushioning made from lightweight, responsive PEBA foam. This stuff is ultra-bouncy and brings serious energy return, so every stride feels light and springy. It’s great for race days but also holds up well in speed workouts, thanks to its durability and comfort.

Winged Nylon Plate

Wedged inside the foam is a winged nylon plate, which adds a little more flex than a carbon plate, but still very propulsive. The plate adds just the right amount of structure to add some snap to your stride without feeling too stiff, making the Speed 5 a nice option for runners who want to move fast but still enjoy a natural-feeling ride.

Full-Length Longitudinal Groove

One of the subtle but useful upgrades in tech in the Speed 5 is the full-length longitudinal groove along the bottom of the shoe. This groove adds some extra flexibility to the midsole, which makes transitions smoother and the shoe more adaptable to changes in terrain whether you're running on flat roads or gentle hills.

Engineered Mesh Upper

Up top, the engineered mesh upper keeps the Endorphin Speed 5 lightweight and breathable. It hugs your foot securely through the midfoot, while the updated squared-off toe box gives just a bit more space up front, making it a good choice for those longer runs in warmer weather. The breathability of the Endorphin has also been improved, letting heat escape faster and helping your feet stay cool when the pace picks up.

Articulated Heel Counter

Around the back of the Endorphin 5, the articulated heel counter offers a more dialled-in fit without squeezing things in too tight. It wraps around your heel for a locked-in, secure feel that keeps your foot stable and supported through every stride. There’ll be no slipping, no discomfort, just a perfect fit that will increase both your performance and recovery.

Giving the environment a hug with every step

For runners out there who want to give a little back to the environment, the Endorphin 5 is vegan-friendly sneaker made with recycled materials. It’s a small touch, but one that adds a bit of feel-good to your fast run.
