Helion superfoam is lightweight, durable, and temperature resistant, so it performs consistently whether you are running in summer heat or a cool autumn morning. It converts impact energy into rebound rather than letting it dissipate as heat or fatigue.

The Speedboard is an internal propulsion plate that stores energy during the landing phase and releases it at toe-off, giving the Cloudmonster 61 a noticeably snappy feel underfoot. Paired with the rocker shape, it produces a forward-rolling stride that reduces the effort required to maintain pace.

The engineered upper and padded sockliner wrap the foot without restriction, making the Cloudmonster 61 as comfortable on a recovery jog as it is during a two-hour effort. The fit is accommodating enough for runners who spend long periods on their feet outside of training as well.
Product story
The Cloudmonster 61 in Ivory and Midnight is the kind of colorway that earns a second look on the road and at the coffee shop after. The pale ivory upper sits cleanly against the deep midnight sole, giving the shoe a two-tone confidence that works whether you are logging miles before sunrise or walking into a meeting still in your kit. It is a considered pairing, not an accident.
Under that refined exterior lives the same monster-level cushioning the Cloudmonster line is known for. Helion superfoam absorbs landing impact across the full stride, converting force into forward momentum rather than fatigue. The Speedboard positioned through the midsole acts like a loaded spring, adding a snappy, propulsive feel that keeps the ride energized through the final miles of a long run.
The rocker geometry built into the Cloudmonster 61 is what separates it from a shoe that simply feels soft. The curved sole geometry guides the foot through a natural toe-off, so each stride flows forward rather than stalling at the push. Combine that with the soft knit upper and padded sockliner and you have a shoe engineered to reduce the work your legs do over distance, not just to protect them.
The Cloudmonster 61 Ivory and Midnight suits runners who want maximum cushion without a maximalist aesthetic. It is a strong choice for daily training at easy to moderate paces, long weekend runs on asphalt or packed paths, and recovery days when your feet need a break but your schedule does not allow one. If you tend to favor shoes that transition cleanly from run to the rest of your day, this colorway delivers exactly that.
