Hollow cushioning pods compress on landing and rebound on toe-off, calibrated in the Cloudmonster 1 for sustained comfort across high-mileage days rather than short bursts.

The integrated Speedboard works with Helion foam to store and return energy through the stride, keeping each step feeling efficient without the stiffness of a traditional carbon plate.

Hidden eyelets give the Steel and Eclipse colorway an uncluttered silhouette, while the rubber outsole maintains grip on roads and wet pavement throughout a long day.
Product story
The Cloudmonster 1 in Steel and Eclipse was designed for runners who log miles in the early hours and keep moving well into the afternoon. The cooled grey of Steel pairs with the depth of Eclipse to create a colorway that transitions naturally from the road to everything that follows. It is a shoe that earns its place in a daily rotation without announcing itself loudly.
Under the foot, CloudTec cushioning pods compress on landing and rebound with each stride, tuned here for all-day wear rather than race-day intensity. The Helion foam midsole absorbs road shock while the Speedboard propulsion plate guides energy forward through each toe-off. Together they create a ride that feels planted on the way down and lively on the way up.
The Cloudmonster 1 fits naturally into recovery runs, long easy days, and any session where you need cushioning to do real work. Hidden eyelets keep the upper profile clean and snag-free, and the rubber outsole provides reliable grip on road and light wet surfaces. Runners who spend time on their feet outside of training will find the transition from sidewalk to any indoor surface uneventful.
This shoe suits men who want a single shoe that handles both structured training blocks and everyday wear without compromise. Whether you are returning to consistent mileage after a break, building a base for a fall race, or simply need a shoe that can carry you through a long shift and a walk home afterward, the Cloudmonster 1 in Steel and Eclipse is equipped for it.
