Helion superfoam is lightweight, temperature resistant, and highly resilient, so it cushions hard landings without packing down over time. You get the same soft, protective feel on mile one as you do on mile twenty.

The Speedboard propulsion plate works with the rocker geometry to convert your landing energy into forward momentum. The result is a stride that feels effortless and propulsive rather than heavy and plodding.

The engineered knit upper conforms closely to the foot while staying breathable and light. The soft sockliner underneath adds another layer of comfort for runs where every bit of feel-good matters.
Product story
The All White colorway strips away every distraction and lets the Cloudmonster 61's architecture speak for itself. Those hollow CloudTec cushioning pods along the outsole, the sweeping rocker profile, the sculptural midsole geometry, all of it reads clearly against the unbroken white canvas. It is a shoe that turns heads on the track or the city block without trying too hard.
Underneath that clean exterior, the Cloudmonster 61 is doing serious work. Helion superfoam absorbs the shock of each foot strike while springing back quickly, so energy is not lost between steps. The Speedboard propulsion plate channels that rebound into forward drive, and the rocker shape keeps your stride rolling through the toe-off phase with almost no extra effort required from your legs.
This is a shoe built for distance but comfortable enough for everyday wear. Whether you are logging long training runs before a half marathon, walking to a meeting in clean white sneakers, or putting in a recovery jog between harder sessions, the Cloudmonster 61 earns its place. The soft sockliner and knit upper manage temperature and reduce friction across miles that stack up quickly.
The Cloudmonster 61 suits runners who want maximum cushioning without sacrificing the snappy, energetic ride that defines On. It is a strong choice for heavier runners, those returning from injury who need extra protection underfoot, or anyone whose weekly mileage demands a shoe that absorbs impact session after session. The All White finish makes it equally at home off the road, a versatile performer that does not need a separate lifestyle shoe.
