CloudSwift – Rock Slate
Cloudswift by On-Running is engineered with Helion™ superfoam for cushioning with zero compromises. It’s light on weight but big on energy return and durability. In short, everything you need to run the city.
The Cloudswift performance running shoe, the first shoe to feature On’s new Helion™ superfoam. The Helion™ foam combines properties other foams can’t, delivering durability and rebound at a previously impossible level. The unique new On Helion™ foam is formed of a special structure fusing stable, hard elements and softer, elastic segments. This enables greater durability without adding weight and more rebound without sacrificing cushioning. Thanks to its temperature resistance capability, the cushioning stays premium – no matter if it’s cold or warm outside. Its enduring energy-return properties offer protection from the road and performance for the run.
“No compromises” was the mantra when we set out to create this new superfoam,” explains Olivier Bernhard, On Co Founder and multiple Ironman champion. “As a runner, you need your shoe to perform at its best so you can too. You won’t say yes to second best.
Since no other foam was able to offer what On-running wanted, they decided to build their own. Helion™ is a lighter, softer, and more agile foam for a ride that feels more alive every step of the run.”
The all-new Cloudswift is made for urban runners who like to keep their shoes light and swift yet still have superior cushioning and road protection. While newly shaped Cloud elements on the sole collapse diagonally to increase horizontal cushioning, durable rubber reinforcements provide enhanced traction. In the forefoot, Cloud elements connect at the central channel for a more directional push-off without energy loss.
