The Cloudmonster 3 in Black | Eclipse is engineered for runners who favor a clean, low-profile look that transitions from early morning training blocks to post-run errands without skipping a beat. The deep black colorway with its midnight eclipse tones keeps the shoe visually grounded, letting the ride quality speak for itself rather than the colorway doing the talking.

At the core of every Cloudmonster 3 is a triple-layer CloudTec cushioning system, the most advanced CloudTec configuration On has built into this series. Each hollow pod compresses independently on landing to absorb impact across the full foot strike, then rebounds sharply to return that energy forward. Helion superfoam through the midsole adds a buoyant, resilient feel that holds up across long mileage without packing down.

The Speedboard propulsion plate sits between the foam layers and works with the shoe's enhanced rocker geometry to tilt energy forward at toe-off, so each stride transitions efficiently rather than stalling at the ball of the foot. A compressed rubber outsole delivers reliable traction on dry road surfaces and light-rain pavement, and the knit upper is engineered to move with the foot and keep air circulating on sustained efforts.

The Cloudmonster 3 in Black | Eclipse suits a wide range of runners: those logging consistent weekly road miles who want durable protection, runners returning from lower-leg fatigue who need a forgiving platform, and heavier-framed athletes who rely on maximum cushioning to stay comfortable through longer distances. If you prioritize a cushioned, forward-rolling ride in a shoe that looks at home in any setting, this is the Cloudmonster built for you.
