On Cloudsurfer vs Cloudsurfer 2: Which One Deserves a Spot in Your Rotation?

Introduction

On’s Cloudsurfer line has always been the odd one out in the brand’s lineup. Where many On shoes lean firm and snappy, the original Cloudsurfer arrived noticeably soft, a plush neutral trainer built around the CloudTec Phase midsole with its diagonal cut patterns. With the Cloudsurfer 2, On has refined the formula rather than overhauled it, and the result is a shoe that finally seems comfortable with what it wants to be: a daily training workhorse.

This comparison walks through the specs, the fit, and the ride of both versions so you can decide which one fits your running.

Specs at a Glance

The original Cloudsurfer was listed at 245 g (about 8.6 oz) in a men’s size 9, with a 10 mm drop. Full stack heights were not published by On, but third-party listings put it at roughly 37 mm in the heel and 27 mm in the forefoot. Weight listings vary slightly between retailers, landing somewhere in the low-to-mid 200 gram range.

The Cloudsurfer 2 comes in a bit heavier at 261 g (9.2 oz) in a men’s size 9, with a 9 mm drop. Official stack heights have not been published, but the most likely explanation is an extra millimeter of foam under the forefoot, adding cushioning where the foot lands. Some of the weight gain also traces to the redesigned, more substantial outsole.

Fit and Upper

Up top, the two shoes are close. Both uppers breathe well, and it is hard to claim the second version is dramatically more breathable when the first was already solid in that regard. Width is gracious in both: normal through the heel and midfoot, maybe slightly wide in the forefoot, with a decent amount of volume throughout.

The differences show up in the details. The heel collar on the Cloudsurfer 2 is plusher, and the updated tongue is the standout change. It is thicker than the original’s, holds its structure well, and has a slight texture that grips the top of the foot better. It is not gusseted, but the hold in that region improves noticeably without creating pressure.

The lacing system is also more traditional on the Cloudsurfer 2 across its full length, with elastic eyelets only at the very top and bottom. The original’s lacing layout, with its segmented elastic sections, could tangle and needed fiddling to lock down properly. The net effect is that the Cloudsurfer 2 simply holds the foot to the platform better, which is a meaningful upgrade in itself.

Ride and Midsole

The original Cloudsurfer felt remarkably soft on first contact, partly because of the CloudTec Phase geometry with its diagonal cuts through the midsole, which gave the shoe a lot of give. The Cloudsurfer 2 feels a touch firmer, though that seems to come more from the outsole than a change in the foam itself.

The outsole on the new version is definitely thicker, and the foam feels like it has a little more backbone to it, possibly making it more durable for daily training. It is still a plush experience, just not maximal plush. The slightly firmer tuning gives the shoe a balanced rocker profile, and the foot no longer wants to drift laterally on the forefoot the way it could in the original.

Grip is another clear step forward. On redesigned the outsole with more coverage, and even on runnable dirt the traction feels noticeable. Neither shoe offers real stability features; both are neutral trainers with very gentle sidewalls and minimal flaring. With official stack figures still unconfirmed, expect the Cloudsurfer 2 to sit close to that 37 mm heel figure, possibly a touch higher.

The bigger picture is that the Cloudsurfer 2 finally commits to being a daily trainer. The original felt a little unsure of its identity, caught between a speed shoe and an easy-day trainer. The new version, with its firmer yet structured plushness, solid hold, and grippy outsole, feels like a proper daily training shoe that can still pick up the pace in rhythm when you want it to. If you want something lighter and snappier, On’s Cloudsurfer Next is positioned as the lightweight trainer option in the family.

Which One Should You Buy?

If you liked the original Cloudsurfer, the second version should work for you. The DNA is intact, and the updates make it more daily-trainer friendly rather than reshaping the shoe entirely. The Cloudsurfer 2 is the better pick for most runners: better foot hold, a more consistent ride, improved grip, and foam that holds its integrity better over daily miles.

The original Cloudsurfer still makes sense if you prioritize a softer, more yielding feel and can find it at a discount, but it is the less complete package of the two.

Conclusion

The Cloudsurfer 2 is a focused refinement rather than a redesign. On kept the plush neutral character that made the original appealing, then sharpened the upper, outsole, and ride into something that genuinely works as a daily trainer. For runners shopping in this category, version two is the one to reach for.
