Product Details:
Don't you love it when a shoe's name tells you exactly what it is? Well, you don't have to be a pro or run ultras to enjoy its benefits, but you can trust that's exactly what the On Cloudultra Pro is crafted for. It's a flagship trail racing super shoe, lab tested and trail validated by elites at some of the biggest ultras in the world.
With enduring rebound that helps you feel fresher for longer, the Helion HF superfoam is also tuned for trail control. To enhance your surefooted experience, the CloudTec pods are cleverly designed to compress slightly more in the center than along the perimeter. This improves stability without having to widen the base excessively, which also helps you pick your landings with greater agility.
Adding propulsive pop to your strides is an embedded fiberglass Speedboard. Through athlete testing, fiberglass proved superior to carbon, especially on uphill sections. Coupled with a strong rocker shape, this powerful shoe helps keep your long-distance pace flowing swiftlyeasier and longer than ever. Finished with a hydrophobic leno weave upper and On's most advanced Missiongrip outsole ever, you'll feel dialed, confident, and ready to rock.
Step to the start line and turn your wildest ultra dreams into reality. The On Cloudultra Pro is built to propel you every step of the way, through the finish line and beyond.

We measure every shoe in-house to provide accurate and consistent details.

Weight
The weight is based on a Men's size 9 for Men's and Unisex shoes or Women's size 8 for Women's shoes. The weight listed is for a single shoe, including the laces.

Heel Stack
The heel stack refers to how high your heel sits above the ground when wearing shoes. Based on Men's size 9 as the standard.

-
Heel-toe Offset
Heel-toe offset (drop) is the difference in height between the heel stack and the forefoot stack. We use the number given to us by the brand.
How We Measure Shoe Fit
