Helion superfoam is lightweight, durable, and temperature-resistant, absorbing impact on landing while returning energy through each stride rather than simply muffling it.

The Speedboard propulsion plate works with the shoe's rocker geometry to create a snappy, efficient toe-off that keeps momentum building rather than stalling at the end of each step.

An engineered upper with a soft sockliner wraps the foot in next-level comfort, moving with natural foot motion and reducing friction across long runs and high-mileage weeks.
Product story
The Cloudmonster 61 in Moon | Fawn was designed for women who want their gear to look as considered as their training. The Moon tone sits at the cool, misty end of the spectrum, balanced by the quiet warmth of Fawn, producing a pairing that works on the road at dawn and off it at the coffee shop after. It is a colorway for runners who appreciate restraint over flash.
Underneath the surface, the Cloudmonster 61 delivers On's maximum-cushion road experience. Helion superfoam absorbs impact on landing, returning energy instead of deadening it, while the Speedboard propulsion plate snaps through each toe-off with efficiency you can feel from the first kilometer. The rocker geometry guides the foot through a natural forward arc so the shoe does some of the work your legs do not have to.
The Cloudmonster 61 earns its place in long-run rotation, easy-effort days, and recovery miles alike. Women training for their first half marathon, working through higher weekly mileage, or simply looking for a shoe that will not punish tired legs will find it purpose-built for exactly that kind of sustained, forgiving use. The soft sockliner and engineered upper wrap the foot without pressure points.
The Cloudmonster 61 suits women across a wide range of paces and backgrounds: the recreational runner who prioritizes comfort on every outing, the experienced racer logging easy-day miles, and anyone who spends long hours on their feet and needs a shoe that respects that. In Moon | Fawn, it also happens to be a shoe you will want to lace up simply because it looks the part.
