The Cloudstratus is inherently stable, thanks to On’s engineering.
On built a wide base beneath the Cloudstratus that gives the shoe its substantial stability. Testers never felt their feet roll off the side of the footbed, even around tight corners. And unlike other On running shoes, the Cloudstratus fuses the forefoot Clouds together to form a single forefoot platform, which makes for a confident toe-off.
The clouds are chiseled from Helion foam, the same cushion used in the new On Cloudswift. Helion—pronounced hee-lee-on—is firm underfoot, giving the shoe a stable landing.
On even added a second helping of cloud cushions to increase the shoe’s stamina. The two layers of Clouds work in sync, On says: the first layer collapses when your foot hits the ground and then waits to release its energy; the second layer absorbs even more impact and adds extra propulsion to the system when it springs back into shape.
Like other On running shoes, the Cloudstratus employs the company’s patented Speedboard. Designers sandwiched the plastic insert between the midsole and upper to give the shoe an extra spring. The Speedboard makes the shoe stiffer than other running shoes on the market, but it gives it a snappy step.
Every part of the On Cloudstratus is designed to help you squeeze more miles out of your run.
The top-notch stability inherent in its wide base alleviates any wobble without making it clunky, and the fused forefoot clouds provide a solid base to push off from. On top, the clever star lacing system allows for more customization and relieves tightness on the widest part of the foot by moving the first set of eyelets closer toward the toe.
While the ankle collar rode up a little too high for one of our runners, it didn’t cause any real problems.
If you’re looking for a burly and stable running shoe, the On Cloudstratus has everything you need.
