The same CloudTec pods that define the Cloudmonster series compress on impact and rebound with each stride, delivering a soft, responsive feel across easy runs and long training days alike.

A Speedboard propulsion plate runs through the midsole to enhance stability and encourage a smooth forward roll, reducing the effort required to maintain pace over distance.

The haptic mesh upper and perforated microfiber tongue keep air moving around the foot, while TPU eyelet stays add structure without adding visual weight to the clean Glacier and Alloy finish.
Product story
The Cloudmonster Void in Glacier and Alloy is built around contrast: a cool, near-neutral colorway on the outside and a maximally cushioned ride underneath. The Glacier upper sits alongside steely Alloy accents in a way that reads almost architectural, subdued enough to pair with streetwear but purposeful enough for a long training block.
The ride starts with the same CloudTec cushioning pods that defined the original Cloudmonster. Those hollow pods compress precisely on landing and then rebound to return energy, while the Helion superfoam midsole keeps the overall package lightweight across long efforts. An embedded Speedboard propulsion plate stiffens the forefoot just enough to encourage a natural forward roll, so the shoe never feels like it is working against you.
The Cloudmonster Void was redesigned with all-day wear in mind, and the upper details reflect that goal. A haptic mesh construction allows airflow throughout, while a perforated microfiber tongue reduces pressure points during extended wear. Rubber outsole pads are positioned for grip on both wet pavement and indoor surfaces, making this a capable choice from a rainy morning run to an afternoon spent on your feet.
This colorway is aimed at the runner who has settled on a neutral, go-with-everything shoe and does not want to compromise on performance to get it. The Glacier and Alloy combination works as well beside running shorts as it does with chinos. If you put in real mileage and want the shoe to hold up visually and mechanically over time, the Cloudmonster Void is a considered, durable answer.
