Helion superfoam is lightweight, durable, and temperature-resistant, so it keeps its feel whether you are running a cold winter morning or a hot summer evening. It absorbs impact on landing and springs back quickly, giving you a ride that stays consistent mile after mile.

The snappy Speedboard propulsion plate sits inside the midsole and converts the energy of each landing into forward drive. It is what separates the Cloudmonster 61 from a shoe that simply cushions from one that actively assists your stride.

The unique rocker geometry rolls your foot naturally through each step without requiring you to muscle through the transition. On tired legs, this effortless forward momentum is the difference between finishing strong and grinding it out.
Product story
The Cloudmonster 61 in Alloy | Silver turns heads for the right reasons. The cool alloy tones and silver accents give this shoe a refined, purposeful look that moves as naturally from morning runs to post-workout errands as it does from a training block to race-day warmup. It is the kind of colorway that reads serious without announcing itself.
Under the foot, On's Helion superfoam does the heavy lifting. It is light, temperature-resistant, and engineered to absorb impact on landing while giving you a responsive bounce at toe-off. The Speedboard propulsion plate works in concert with the foam to snap energy back into your stride, so the shoe pushes you forward rather than just padding the road beneath you.
The rocker geometry is what runners notice first and what keeps them coming back. Rather than forcing you to power through each step, the shape guides your foot through a natural forward roll, reducing the effort required on tired legs and long runs alike. Pair that with a soft sockliner and an upper that wraps without squeezing, and you have a shoe that feels as good at mile twenty as it does at mile one.
The Cloudmonster 61 suits men who want maximum cushioning without a mushy, undefined ride. If you are building mileage after time off, training through a heavy week, or simply want a go-to daily trainer that earns its place in a crowded rotation, this is that shoe. The Alloy | Silver colorway makes it versatile enough to wear past the finish line.
