The On Running Cloudmonster 2 "White Frost" is the evolution of one of the brand's most bold silhouettes — a running shoe that delivers extraordinary performance and a striking look, perfect for those seeking a sneaker with power, cushioning, and style. With a sophisticated colour combination of grey tones and subtle blue accents, the Cloudmonster 2 stands out both on the streets and in the running world.
The upper is crafted from breathable technical mesh that keeps feet cool and ventilated, even during longer and more intense runs. The design is adaptive and comfortable, with a lightweight feel that doesn’t compromise on the support runners of all levels need.
