What changed: Corrected foam, geometry, drop, weights, widths, ride character, evidence conflict, comparisons, sourcing, lifecycle, and affiliate status.
Quick Hits
- •The catalog uses 37/28mm exact-model geometry and a 9mm drop.
- •Cloudsurfer 2 uses Helion, not the prior article's unsupported Helion HF claim.
- •Independent sources disagree substantially on total stack at 37/28mm versus 32/23mm.

On Cloudsurfer 2 Review: Audited 9mm Daily-Trainer Specs
Disclosure: TrainingPlan has not hands-on tested this exact model. This research-based review uses On's exact product page and independent exact-model evaluations. No exact-model Amazon US listing is currently verified.
Quick Verdict
The On Cloudsurfer 2 is a current neutral road trainer released in February 2025. The audited catalog uses 37mm at the heel, 28mm at the forefoot, a 9mm drop, 9.2-ounce men's and 7.8-ounce women's references, regular and wide fits, and MSRP: $160 MSRP. The midsole uses Helion foam with computer-shaped CloudTec Phase cavities and a pronounced rocker.
It is best for runners who want a smooth, relatively controlled daily ride rather than the very soft sensation associated with the previous Cloudsurfer. The second generation can cover easy miles, steady aerobic running, and ordinary daily training. Its firming, toe spring, and premium price may not suit runners seeking flexible or plush cushioning.

What Changed
The previous article listed Helion HF, a generic pod construction, 33/25mm, an 8mm drop, 9.5/8.1-ounce weights, and standard width only. Exact-model evidence supports Helion foam, retuned CloudTec Phase geometry, 37/28mm, 9mm, 9.2/7.8 ounces, and wide availability. It also incorrectly framed the shoe as automatically soft and capable at everything.
Stack evidence is not unanimous. Doctors of Running reports 37/28mm, while RoadTrailRun publishes 32/23mm. Both calculate 9mm, but total height differs by 5mm. Runtime uses the 37/28mm exact-model reference and preserves the conflict. The unverified Amazon link was removed because listing generation and ASIN were not documented together.
Ride and Intended Use
CloudTec Phase uses shaped voids designed to collapse in sequence as the runner rolls forward. In version 2, the geometry combines with a firmer Helion formulation and substantial toe spring. Independent testers describe a smooth transition and more controlled landing than the prior generation, but also less of its soft, sinking character.
The practical role is daily road mileage: easy runs, routine aerobic sessions, and some steady work. It lacks a plate and does not need one for that purpose. It is less natural for speed intervals or runners who want ground feel. Choosing running shoes explains why a distinctive sole design should still be evaluated through comfort and training use.
Fit and Sizing
On offers standard and wide versions. Reviews generally describe a secure midfoot and heel with true-to-size length, while the forefoot shape and rocker interaction remain individual. The upper is streamlined rather than heavily padded, and the wide option is preferable to adding length for a broad foot.
Try normal size first and confirm that the toe spring does not press uncomfortably under the forefoot. Compare the more cushioned On Cloudmonster 2 or the more supportive On Cloudrunner 2 if this neutral, rockered fit is not right.
What Works Well
Smooth transition is the model's clearest strength. The sequenced geometry keeps the moderate cushion moving, and the shoe remains lighter in the women's reference than many daily trainers. The firmer second-generation construction also gives the tall platform a more predictable feel for runners who found the previous version overly soft.
Regular and wide fits broaden accessibility. The outsole coverage and controlled ride support a high durability classification, although that remains an evidence-based editorial assessment rather than a mileage guarantee.
Tradeoffs
Version 2 may disappoint runners specifically seeking the prior Cloudsurfer's softness. The prominent toe spring can feel intrusive during walking or for runners whose mechanics do not match it. At MSRP: $160, the shoe competes with many capable trainers and needs to provide a clear fit or ride advantage.
The stack disagreement also cautions against presenting one method as universal. Inspect changing foam feel, outsole traction, and upper security over time using when to replace running shoes.
Who Should Consider This Shoe
Consider Cloudsurfer 2 if you want a neutral daily trainer with a smooth rocker, prefer controlled moderate cushioning, and fit either the regular or wide version. It can be particularly useful for easy-to-steady road mileage where transition matters more than bounce.
Who Should Look Elsewhere
Look elsewhere for an ultra-soft landing, minimal toe spring, dedicated stability, or a budget workhorse. ASICS Novablast 5 is livelier and higher; Nike Pegasus 41 offers a more conventional daily geometry.
Cross-Brand Comparison
Compared with Novablast 5, Cloudsurfer 2 is lower, firmer, and more transition-focused. Compared with Pegasus 41, On uses more distinctive cavity geometry and a stronger rocker. None is categorically superior; foot shape and preferred motion are decisive.
Same-Brand Comparison
Cloudmonster 2 provides more cushion and mass. Cloudrunner 2 adds support-oriented geometry. On Cloudflow 4 is lighter and firmer for faster daily use. Cloudsurfer 2 sits in the smooth neutral middle.
Value
MSRP: $160 is premium for a non-plated daily trainer. Value is reasonable when the CloudTec Phase transition and fit are a clear match, less so if the shoe functions like any ordinary trainer for the buyer. No affiliate CTA appears without exact-model marketplace verification.
Final Verdict
On Cloudsurfer 2 is accurately a 9mm-drop, 37/28mm reference daily trainer with Helion foam, CloudTec Phase, 9.2/7.8-ounce weights, and regular and wide fits. Its smooth, firmer ride is coherent and useful, but pronounced toe spring, measurement conflict, and MSRP: $160 price deserve explicit consideration.
Key Takeaway
Cloudsurfer 2 is a smooth, controlled daily trainer rather than an ultra-soft one; its pronounced toe spring, fit, and $160 price should drive the decision.
