The On Cloudmonster 2 is a max-cushion daily trainer priced at ₹15,999 in India. The verifiable specs are a 40 mm heel and 34 mm forefoot stack, a 6 mm drop, a 290 g unit weight, Helion superfoam and an internal Speedboard. Those numbers, set against the peer-reviewed literature on cushioning, drop and daily-trainer use, give us a defensible picture of who the shoe suits and how it should be used in Indian conditions.
The specifications, in context
The Cloudmonster 2 sits clearly in the max-cushion daily-trainer category. The 40 mm heel and 34 mm forefoot are at the upper bound of contemporary daily-trainer stack heights. Understanding what the research says about stack and drop is the right starting point.
Stack height and impact attenuation
A 2023 review in Sports Medicine concluded that increased midsole stack height is associated with reduced vertical impact peaks in laboratory testing, though the magnitude varies with foam composition and runner mass. The Cloudmonster 2's Helion superfoam, paired with the Speedboard, is the mechanism through which On attempts to convert that increased stack into a controlled, propulsive ride rather than a soft, unstable one.
Drop and lower-leg loading
The 6 mm drop is moderate. Published work on heel-toe drop, summarised in a 2020 BJSM narrative review, suggests that lower drops shift mechanical load distally toward the Achilles and calf, while higher drops shift load toward the knee. The 6 mm figure is a reasonable middle position for runners with no specific lower-leg history; runners coming from a 10 mm drop should expect a measured adaptation period.
Weight and category fit
At 290 g, the Cloudmonster 2 is firmly in daily-trainer territory rather than race or tempo. The literature is consistent: shoe mass is one of the more robustly demonstrated determinants of running economy, with each 100 g per shoe associated with roughly a one percent change in oxygen cost at submaximal paces. A 290 g shoe is not a racing tool; it is a training tool, and the trade-off is durability and cushioning rather than speed.
Who the Cloudmonster 2 suits
The category, geometry and price together suggest a defined buyer profile.
The high-volume neutral runner
If your weekly distance is 50 to 80 kilometres and you do not need pronation control, a max-cushion daily trainer is one of the better-supported gear choices in the literature. The Cloudmonster 2 fits that brief. Long easy runs and recovery jogs are where the 40 mm stack returns the clearest benefit.
The marathon-training runner
For 16-week marathon blocks, a max-cushion option for long runs is a defensible second shoe in a rotation. Rotation itself is supported by injury-risk literature: a 2013 study in the Scandinavian Journal of Medicine and Science in Sports reported lower injury rates among runners who rotated between two or more shoes versus those who used one. Pair the Cloudmonster 2 with a lighter tempo shoe and a race-day option; the 2026 super-shoe comparison can help select the race-day tool.
Who should consider another category
Runners with significant overpronation requiring stability features, runners who train almost exclusively at fast paces, and runners new to running who would benefit from a lower-stack, more proprioceptive shoe should look elsewhere. Our On shoes in India page lists other On options across daily and stability categories.
What the Cloudmonster 2 cannot do
Bounded claims hold up better than unbounded ones.
It is not a race shoe
The 290 g weight and the daily-trainer Speedboard are not engineered for race-day economy at the level of a 200 g carbon-race shoe. The published lab work on plated race shoes consistently shows greater economy benefits at fast paces than tempo-class trainers. If you are chasing a marathon PB, this is not the tool for the start line.
It is not a stability shoe
On positions the Cloudmonster line as neutral. The Speedboard provides some torsional integrity, but the shoe does not include a medial post or pronation-control geometry. Runners with documented medial collapse should select a category-appropriate shoe.
It is not a trail shoe
The outsole is built for tarmac. Indian off-road conditions, particularly during monsoon, will both reduce grip and accelerate outsole wear. Use a dedicated trail shoe for unpaved routes.
Indian-conditions notes
India-specific use cases are where most generic global reviews stop being useful.
Heat and foam behaviour
Helion superfoam, like most TPU- and PEBA-blend midsoles, is rated to perform consistently across the temperate range. Above 32 degrees Celsius, all current-generation superfoams soften measurably, which is documented in materials-science literature on running shoe midsoles. For Chennai, Mumbai and pre-monsoon Delhi, plan harder sessions for the cool window, 5 to 7 a.m. or after sundown.
Monsoon use
The outsole sheds water adequately on tarmac but offers no specific aquaplaning protection. On wet, polished surfaces such as Indian footpaths after rain, slow the pace and shorten the stride.
Durability expectations
The published durability range for max-cushion daily trainers is broadly 500 to 800 kilometres, with significant individual variance. Track total mileage and judge retirement by feel, not calendar. The midsole compresses gradually; the visual signal is creasing along the lateral midfoot.
City-specific use
The Cloudmonster 2 handles the mixed urban surfaces typical of Indian cities, smooth bitumen, broken tarmac, occasional stone paving, at easy pace. Hard track sessions and trail use sit outside its design envelope. For runners alternating between city training and the occasional unpaved route, a dedicated trail shoe is the rational second purchase. The category-mate options on the On India page include On's trail line for that role.
Decision and next step
The Cloudmonster 2 is a category-appropriate max-cushion daily trainer for neutral runners with consistent weekly volume. Within the limits of what the literature supports, it is a defensible choice for long easy runs and recovery jogs. It is not a race shoe and does not pretend to be. Compare it on specs against category mates using our shoe comparison tool, browse the wider category at gear shoes, and if you have not yet built the training plan that will use this shoe, our plan generator is the right next step.
