Helion superfoam is lightweight, durable, and temperature resistant, so the cushioning feel stays consistent whether you run in cool morning air or warmer afternoon conditions.

The Speedboard propulsion plate works with each foot strike to return energy forward, giving the Cloudmonster 61 a lively, responsive character that stands out in the max-cushion category.

The Cloudmonster 61's distinctive rocker shape reduces the effort needed to transition from landing to push-off, making sustained paces feel more effortless on long runs and easy days alike.
Product story
The Cloudmonster 61 in Frost | Wash arrives in a palette that feels quietly confident: a cool, pale frost tone softened by a washed finish that wears well whether you are logging easy miles before sunrise or heading out on a longer weekend run. It is a colorway that doesn't demand attention, which makes it pair with nearly anything in your rotation without effort.
Under that clean exterior, the Cloudmonster 61 is doing serious work. Helion superfoam absorbs impact on landing so your legs take on less stress, and the Speedboard propulsion plate stores and releases energy with each stride. The result is a ride that feels springy and responsive without being harsh, a combination that holds up across many miles.
The unique rocker shape of the Cloudmonster 61 encourages your foot to roll forward naturally, which reduces the effort it takes to maintain momentum. That geometry, combined with a soft sockliner and a breathable upper, makes this shoe a strong choice for daily training, easy long runs, and recovery days where comfort is the priority.
The Cloudmonster 61 suits runners who want maximum cushion without feeling buried in the shoe. Whether you are building mileage for a half marathon, recovering from a hard week of training, or simply running because you enjoy the feeling of a shoe that works with your stride, the Frost | Wash colorway gives you a shoe that is ready for all of it.
