On's Cloudmonster line has spent four years establishing itself as a reliable platform for runners prioritizing maximal cushioning. The third iteration arrives as a test case for the Swiss brand's latest material breakthrough—LightSpray, an ultralight upper construction introduced in 2024 that fundamentally shifts how the shoe manages weight while preserving responsiveness.

LightSpray functions as a next-generation solution to a familiar problem in running footwear: achieving minimal mass without compromising durability or breathability. The technology integrates throughout the upper, reducing overall shoe weight in a category where grams matter. For the Cloudmonster 3 Hyper specifically, this means the characteristic cushioning stack remains intact while the upper itself becomes significantly more efficient.

Design & Technology

The Cloudmonster franchise has always centered around On's proprietary cushioning philosophy—soft, responsive, and generous underfoot. The third generation maintains that DNA while the LightSpray integration represents a controlled evolution rather than a radical departure. The upper's construction becomes the focal point, with the material's spray-applied nature allowing for precise placement and reduced material layering.

The Hyper designation signals this particular colorway within the broader Cloudmonster 3 launch, though On has positioned the model as the flagship expression of what LightSpray can accomplish at scale.
