Helion superfoam compresses on impact to absorb shock, then rebounds quickly to put energy back into your next stride. It stays responsive across a wide range of temperatures, making it reliable for both summer track sessions and cooler morning runs.

The embedded Speedboard propulsion plate amplifies the rebound from Helion foam, giving the Cloudmonster 61 a snap at toe-off that most max-cushion shoes sacrifice for softness. The result is a ride that feels both protected and propulsive.

The Cloudmonster 61's engineered rocker geometry guides the foot from landing through toe-off without requiring the runner to muscle through a thick stack of foam. It creates a smooth, natural forward momentum that reduces fatigue over long distances.
Product story
The Cloudmonster 61 in Ivory and Pearl is a deliberate departure from the darker, high-contrast colorways that define much of the Cloudmonster line. This neutral, almost luminous palette suits runners who want the shoe to feel as clean as the ride itself, whether that is an early morning long run or a casual day on the road. It pairs easily with training kit without asking for attention, which makes it one of the more wearable expressions of a shoe that is anything but subtle underfoot.
Beneath the soft engineered upper, On has packed in Helion superfoam, a proprietary compound engineered to absorb impact on landing while snapping back quickly to return energy with each toe-off. The Speedboard, a stiff propulsion plate embedded through the midsole, amplifies that rebound and keeps the transition from heel to forefoot feeling urgent and connected. Together these two systems make the Cloudmonster 61 feel faster than a shoe this cushioned has any right to feel.
The unique rocker geometry is the third pillar of what makes this shoe work. Rather than forcing a runner to do the work of rolling through a thick midsole, the Cloudmonster 61 uses its curved profile to guide the foot forward naturally, reducing the dead feeling that plagues less well-engineered max-cushion shoes. That rocker shape also makes it a genuinely comfortable option for runners dealing with heel or forefoot sensitivity, as it quietly manages ground contact without demanding anything extra from the runner.
The Cloudmonster 61 in Ivory and Pearl suits a wide range of men, from high-mileage marathon builders putting in weekly long runs to commuters and nurses who need their feet to feel good through a full shift. The soft sockliner and accommodating upper make it comfortable from the first wear, and the light, durable foam construction holds up across hundreds of miles without losing its signature bounce. If you have been waiting for a max-cushion On shoe that does not look like it is trying too hard, this colorway was made for you.
