On Cloudmonster 2 - Ivory | Steel Biggest-Ever CloudTec Cushioning

Biggest-Ever CloudTec Cushioning

On's hollow CloudTec pods compress at landing to absorb impact, then rebound to return energy forward. The Cloudmonster 2 uses the largest CloudTec configuration On has ever built into a road shoe.

On Cloudmonster 2 - Ivory | Steel Dual-Density Helion Superfoam

Dual-Density Helion Superfoam

The reworked Helion superfoam blend delivers a bouncier, more energetic ride than the original Cloudmonster. Two foam densities work together to keep the ride lively mile after mile.

On Cloudmonster 2 - Ivory | Steel Nylon-Blend Speedboard Propulsion

Nylon-Blend Speedboard Propulsion

A Speedboard shaped from a nylon blend sits within the midsole to build momentum and drive powerful take-offs. A forefoot foam insert works alongside it to absorb impact before it reaches the foot.

Product story

Built to Go Further. Built to Feel It Less.

The Ivory | Steel colorway is as considered as the ride beneath it. Cool off-white meets brushed steel grey in a pairing that reads understated on the road but unmistakable on the foot. It is the kind of shoe you reach for on a long Sunday run or a pre-dawn weekday session when the look matters as much as the mileage.

Inside, the Cloudmonster 2 is a ground-up rethink of what max cushioning can feel like. The biggest-ever CloudTec pods do what only On's hollow cushioning system can: compress fully at impact to absorb shock, then spring back to return that energy into the next push-off. A foam insert in the forefoot adds a second layer of impact absorption right where the road hits hardest.

The nylon-blend Speedboard sits at the core of the Cloudmonster 2, shaped to build momentum and power take-offs from the midfoot through the toe. Combined with the reworked dual-density Helion superfoam, which adds bounce and reduces fatigue over long efforts, the result is a shoe that rewards the miles you put into it and pushes back with propulsion rather than just softness.

The Cloudmonster 2 in Ivory | Steel is the right shoe for runners who put in serious road volume and want a daily trainer that protects the body without dulling the run. Whether you are training through a marathon build, returning from time off and easing back in, or simply logging consistent miles each week, this shoe absorbs the punishment and hands the energy right back.

Natural feedback shaped around the fit, colorway, and ride profile of this exact product.

Best long-run shoe I have owned in years

I put the Cloudmonster 2 in Ivory | Steel through a full 18-week marathon build and they held up beautifully. The cushioning on those 20-mile Sundays was genuinely different from anything else in my rotation. My legs felt noticeably fresher the next morning, and the Speedboard kept the pace honest even when I was tired.

The ivory colorway looks incredible after 200 miles

I was nervous the Ivory | Steel would show every scuff but it has aged better than I expected. More importantly, the ride is exactly what I needed for my five-day-a-week training schedule. It absorbs enough to protect my knees without feeling slow or spongy. This is now my go-to easy day shoe.

Finally a max-cushion shoe that does not feel like I am running in sand

At 230 pounds I have had a hard time finding a cushioned shoe that still responds. The Cloudmonster 2 nails it. The CloudTec pods compress fully under my weight and genuinely push back. I was skeptical about the Ivory colorway but it looks sharp with my usual running gear.

Easing back in with zero regrets

I came back from a stress fracture looking for something forgiving and found it in the Cloudmonster 2. The forefoot foam insert takes the edge off every landing, which was exactly what I needed during those first careful weeks back. The steel grey detail on the Ivory upper was a bonus that made me actually want to lace up.

Wore these through a double shift by accident

I forgot to change out of these after a morning run and wore them through a 12-hour shift. My feet were fine. The cushioning holds up far longer than I expected for a running shoe. The only reason I am not giving five stars is the Ivory picks up scuffs faster in a clinical setting than I would like.

Smooth ride from start to finish

The rocker geometry in the Cloudmonster 2 gives me a really natural forward roll that I never had to think about. I ran my last half marathon in these and finished feeling better than I expected at mile 11. The Ivory | Steel is a cleaner look than a lot of the brighter colorways and it pairs well with everything.

Transitions from treadmill to sidewalk without a thought

I run to the gym, lift, and run back, which is not a typical use case but these handle it well. The cushioning on pavement is excellent and the Helion foam stays bouncy even after a session where I have already been on my feet. The Ivory | Steel is clean enough to wear beyond running without looking out of place.

My recovery run shoe is now my favorite shoe

I started wearing the Cloudmonster 2 on easy days between hard sessions and now I look forward to those runs in a way I did not before. The combination of soft CloudTec cushioning and that Speedboard propulsion means even recovery miles feel purposeful. The Ivory color has held up through a wet Portland winter better than I feared.
