The same iconic cushioning pods from the original Cloudmonster compress on impact and spring back with real energy, giving the Cloudmonster Void a ride that protects without feeling dead underfoot.

A full-length Speedboard runs beneath the foot to provide enhanced stability and a consistent platform, supporting efficient movement whether you are running easy miles or moving through a busy day.

The new technical-inspired mesh upper combines a haptic texture with genuine lightness and breathability, keeping the fit comfortable across long wear sessions while TPU eyelet stays preserve structural durability.
Product story
The Cloudmonster Void starts where the original Cloudmonster left off, carrying over the same iconic CloudTec cushioning that earned the franchise its following. Those hollow cushioning pods still compress on landing and rebound with real energy, giving every step a quality that feels both protective and lively. What the Void adds is a rethought upper and a broader sense of purpose, so the shoe earns its place beyond dedicated training blocks.
At the core of the Cloudmonster Void is a Speedboard that runs the full length of the shoe, providing enhanced stability and guiding your foot through each stride. The perforated microfiber tongue and lightweight breathable mesh work together to keep air moving during long sessions and extended wear. TPU eyelet stays reinforce the lacing system without adding visual noise, keeping the structure precise and the finish durable over time.
The Alloy and Glacier colorway is the quietest version of the Cloudmonster Void, built for people who want a shoe that moves between contexts without announcing itself. The cool gray Alloy base pairs with an icy Glacier accent in a combination that reads as considered rather than understated. It sits equally well against gym wear, casual fits, or technical running kit, which is the point of a shoe designed for versatility above all.
The Cloudmonster Void in Alloy and Glacier suits runners who put in consistent mileage and need a shoe that keeps up across training days, recovery runs, and the hours in between. It is equally well suited to someone who spends long shifts on their feet and wants the benefits of serious cushioning without the visual weight of a maximalist silhouette. If you want a shoe that performs seriously but disappears into your rotation, this is the one.
