Helion HF is On's high-energy foam compound, tuned to absorb impact on hard city surfaces while returning energy with every toe-off. The dual foam construction adds a second density layer so the ride feels both protective and responsive.

A triple-layer CloudTec base gives the Cloudmonster 3 exceptional cushioning depth for a road shoe. Two distinct foam densities work together to soften landings and promote a propulsive, rolling stride geometry.

Silicone laces replace conventional flat laces to deliver a more consistent, slip-free lockdown throughout the run. The perforated sockliner beneath your foot channels airflow to keep the interior comfortable on longer efforts.
Product story
The Cloudmonster 3 in Black | Black is the result of On's ongoing collaboration with Seoul-based design collective POST ARCHIVE FACTION. Where other colorways play with contrast, this one commits entirely to monochrome: black upper, black midsole, black outsole. The effect is a shoe that reads as a single bold object rather than a collection of parts, and it pairs with almost anything a city runner would already own.
The ride is built on Helion HF hyper foam, a high-rebound compound that absorbs ground impact without feeling dead or spongy underfoot. A dual foam construction layers different densities to give you softness at heel strike and a firmer, propulsive feel through the toe-off. A triple-layer CloudTec base provides the cushioning depth that lets the Cloudmonster 3 handle both long training blocks and all-day urban use without fatigue.
The Cloudmonster 3 excels on road and pavement, making it equally at home on a long weekend run, a commute across the city, or a shift that keeps you on your feet for hours. The rocker geometry encourages a natural forward roll, so each stride transitions smoothly rather than stalling at the ball of the foot. Silicone laces replace traditional flat laces for a consistent, grip-forward lockdown that does not loosen over the course of a run.
The Black | Black colorway suits runners who want a shoe that functions at a high level and disappears visually into any outfit. It is sold in both mens and womens fits, and the all-black construction makes it versatile enough to move from a track session to a coffee shop without a change of shoes. If you log serious weekly mileage and want maximum cushioning without sacrificing aesthetic intention, this is the version of the Cloudmonster 3 built for you.
