Who should buy

We believe the On Cloudsurfer Next is an appealing choice for:

  • Runners who appreciate the Cloudmonster 2 but crave a more dynamic ride.
  • Those seeking a narrow, sleek daily trainer with high-quality materials and top-notch build quality.
  • Anyone preferring firmer, stable cushioning over a plush feel in their daily trainer.

Who should NOT buy

We believe heel strikers may find the Cloudsurfer Next less enjoyable due to its narrow heel and low heel-to-toe drop, making it more suitable for midfoot and forefoot strikers. In our view, better options exist for this group of runners, like the Nike Pegasus 41 or ASICS Novablast 4.

Additionally, those preferring a softer running experience may struggle with the Cloudsurfer Next’s firmer midsole, even with the addition of CloudTec Phase. We suggest considering the New Balance FuelCell Rebel v4 or New Balance Fresh Foam X 880 v14, both offering a plush alternative for daily runs at a similar price point.

Cushioning

Heel stack

In our tests, we discovered a slight discrepancy in the heel stack height stated by On. While the Cloudsurfer Next is listed at a 37 mm rearfoot stack, our caliper measured it at 33.8 mm—falling short by 3.2 mm.

This minor reduction in height does bring a subtle decrease in cushioning, but it also enhances stability, creating a more grounded ride.

Forefoot stack

We measured the midsole thickness at 29.3 mm in the forefoot, confirming our initial impression during testing—this model has significantly more cushioning than its sibling, the Cloudsurfer 7.

It’s a bit confusing to navigate On’s lineup with these names. It may seem to you like the Next replaces the 7, but we can confirm that both models will coexist in the lineup.

Drop

On has a reputation for low-to-moderate heel-to-toe drops, and the Cloudsurfer Next stayed true to that trend. Our measurements revealed a 4.5 mm offset—ideal for forefoot and midfoot strikers!

Midsole softness

Note: a low durometer measurement equals a soft material, whereas a high measurement means it's firm.

Many still believe that On shoes lean toward softness, but in our experience here in the lab, they usually land on the firmer side. The CloudTec Phase technology helps by compressing with each stride, yet the ride is still notably firm.

The Cloudsurfer Next embodies this quality well. We measured a softness of 31.8 HA on our durometer, making it one of the firmest daily trainers we’ve tested.

On Cloudsurfer Next Helion foam

While this feel may not suit every runner, those who enjoy a more stable ride will likely appreciate this midsole.

And what about the foam itself? Well, On’s Helion combines EVA and Olefin Block Co-Polymers, offering a denser, more structured feel than ASICS’ FF Blast+. It doesn’t deliver a huge energy return, but for a training foam, it holds up well, especially with the new CloudTec Phase inclined pods that provide a more dynamic feel.

Rocker

The Cloudsurfer Next features a gentle rockered profile from heel to toe, a helpful addition given its firmer-than-average midsole and slightly stiffer structure compared to typical daily trainers.

We also believe a slightly more pronounced heel bevel could enhance the shoe’s flow, especially with its low drop—as this design that may not suit extreme heel strikers.

Toebox width - widest part

In our experience, while the midsole is narrower than most shoes, the toebox felt mostly average. Our digital caliper measured it at 97.3 mm, making this model slightly narrower than the norm, though differences under 2–3 mm are virtually undetectable while running.

For volume, the upper offers minimal stretch, and the toebox height was moderate—adequate for most runners but potentially a touch low for those who need extra room.

Stability

Lateral stability test

A firmer ride might not suit everyone, but it brings clear advantages—especially in stability. A solid landing platform minimizes wobble, and the Cloudsurfer Next exemplifies this benefit beautifully.

Torsional rigidity

The impressive stability of this shoe isn’t just due to its firm foam. We found that its high torsional rigidity—rated at 4/5 from our team in the lab—adds significantly to the supportive feel it provides.

Midsole width - forefoot

We discovered that one reason On managed to keep this shoe lightweight—despite the substantial rubber coverage and dense midsole—is its skinny profile. Measuring 111.6 mm, it’s significantly narrower than most running shoes we test in the lab today.

This streamlined design appeals to those who favor a sleeker build and want to avoid the maximalist, ultra-wide models currently popular. We also understood why On used a firmer midsole, as it pairs well with the narrow platform. A softer foam would likely feel unstable on such a slim base.

Midsole width - heel

In our experience, if the forefoot seems narrow, the heel takes it further. Measuring just 84.5 mm, it’s more reminiscent of a race-day shoe—adding to why we think this model isn’t ideal for most heel strikers, particularly those who need extra stability.

Flexibility

Stiffness

With its firmer midsole, we anticipated a bit more longitudinal stiffness but tested it to confirm.

Our 90-degree test showed a 30.3N result, reinforcing that this shoe might not be flexible enough for daily walks or gym sessions. If that’s a concern, we recommend the On Cloudrunner 2 (21.1N) instead.

Weight

At 9.3 oz or 264g, the Cloudsurfer Next delivers a lightweight ride, and we believe it holds up well in its category. While there are some shoes that feature a similar weight with higher stack like the ASICS Superblast 2, these remain rare in the market.

For us, the Cloudsurfer Next passes this test comfortably. Its padded, cozy upper is a nice bonus without tipping the scales, making it a great balance of comfort and weight for everyday runs.

Breathability

At our lab, we always insist on digging deep to get precise results, and the Cloudsurfer Next showcases this approach when it comes to breathability.

After purchasing the shoe and unboxing it, we expected the toebox to ventilate exceptionally well. However, our smoke-pumping test, conducted under the usual conditions, revealed a different story, delivering a disappointing 2/5 score.

Next, we used an LED flashlight and found that very little light passed through—ventilation in this shoe seems minimal! On the plus side, this design likely adds warmth for colder conditions.

On Cloudsurfer Next microscope

But this is where things get interesting.

On Cloudsurfer Next upper

Under the microscope, the upper’s design appeared packed with ventilation holes, suggesting great airflow. But the black fabric that adds comfort and durability blocks these pathways. Had we only used the microscope, we would’ve been misled for sure.

As expected from On—a brand known for quality—the construction of the upper is flawless. We found no glue marks; everything is neatly crafted, and the padding is impressive, maintaining high standards of execution and manufacture.

Outsole hardness

After less-than-ideal results in the first three tests, we hoped for some redemption in another crucial area of any running shoe—the outsole.

On Cloudsurfer Next outsole

Before firing up the Dremel for a final test, we measured the rubber’s hardness at a fairly average 84.5 HC.

We believe this should offer decent durability, which is a good thing, as traction felt fine but not particularly impressive. And yes, we are pretty sure that the central groove in the outsole will get a few pebbles on gravel roads.

Outsole durability

As we hinted earlier, we fired up the Dremel for a final test on the Cloudsurfer Next, hoping to see a stronger result.

The outcome was good, but not great. We observed a 1.1 mm dent in the rubber—enough to suggest the Cloudsurfer Next can handle regular wear but won’t be the kind of shoe that boasts legendary rubber longevity.

Outsole thickness

We found that 2.5 mm of rubber, though thinner than the average daily trainer, is sufficient for this outsole based on our previous findings. Using a thicker layer would likely have made the ride even firmer, and that would have been a disaster in this shoe.

Tongue padding

With a generous 10.7 mm of foam, On prioritized plush comfort over weight reduction in the Cloudsurfer Next’s tongue, creating a pillow-like cushion that spans the entire length of it, delivering amazing instep comfort.

Removable insole

The stock insole in the Cloudsurfer Next is easily replaceable and, aside from a slight heel flare, doesn’t offer anything distinctive. Therefore, we believe this shoe it’s perfectly compatible with a third-party footbed, allowing for easy customization without issue.
