The same hollow-pod CloudTec system from the original Cloudmonster compresses on impact and rebounds cleanly through each stride, delivering max cushioning without adding unwanted bulk to the ride.

On's Speedboard plate runs through the midsole to enhance stability and smooth out the foot's transition from landing to toe-off, particularly useful on longer efforts when fatigue begins to affect form.

The new technical-inspired mesh upper balances ventilation with structure, while a perforated microfiber tongue and TPU eyelet stays add durability and a clean finish that holds up across daily use.
Product story
The Cloudmonster Void started with a simple question: what if the most cushioned shoe On makes was also one of the most wearable? The Sphinx and Cinder colorway answers that with a palette that moves easily from road to sidewalk, pairing a warm stone tone with a cool ash that reads refined without trying too hard. This is a shoe designed to be reached for every morning, not saved for race day.
Under the hood, the Cloudmonster Void carries the same iconic CloudTec cushioning that made the Cloudmonster a standout in the max-cushion category. Hollow pods along the outsole compress on landing and spring back through toe-off, while the Speedboard plate beneath the foot delivers enhanced stability and guides the transition forward. The result is a ride that feels generous underfoot without ever feeling slow or unresponsive.
The upper is where the redesign is most visible. A new haptic technical-inspired mesh wraps the foot in a texture that is both lightweight and breathable, keeping things comfortable during long runs and warm-weather miles. A perforated microfiber tongue reduces pressure points across the top of the foot, and TPU eyelet stays keep the lacing clean and durable across heavy use. The rubber outsole pads provide reliable grip across both wet pavement and dry paths.
The Cloudmonster Void in Sphinx and Cinder suits runners who put in consistent mileage and want a shoe that keeps up with a full schedule. It works equally well for heavier runners who need reliable cushioning day after day, and for those returning from injury who want protection without sacrificing forward momentum. If your week involves both a long run and a full day on your feet, this shoe was built with that in mind.
