The Cloudsurfer 3 doesn't quite deliver the cloud-like ride its name promises, but after years of testing On shoes, we weren't exactly surprised. This update takes the series in a new direction, combining max-stack cushioning with an incredibly comfortable upper and the premium finish we've come to expect from the brand. However, our lab tests revealed disappointing energy return, and the substantial weight gain became obvious whenever we picked up the pace. In our view, it's a solid choice for casual wear and easy runs, but this ambitious redesign ultimately falls short of its potential.

Pros

  • Extra cushioning for easy and long runs
  • Plush knit upper wraps feet
  • Soft heel collar adds extra comfort
  • Generous rubber coverage
  • Impressive build quality
  • Smooth roll from well-designed rocker
  • More stable than it looks
  • Interesting option for walking + running
  • Works well for heel strikers
  • Keeps the same price

Cons

  • Disappointing performance from new foam
  • Heavier than expected
  • Needs a grippier outsole
  • Firmer than it looks

Awards

Who should buy

In our opinion, the On Cloudsurfer 3 is a great option for:

  • Comfort-first runners seeking a plush, foot-hugging upper that feels great from the first minute.
  • Loyal On fans who prefer sticking with the brand and need a shoe for relaxed, easy miles.
  • Runners who enjoyed the Cloudsurfer 2 but wished it had more cushioning underfoot.
  • Anyone in the market for a max-cushioned shoe for walking or all-day standing.

Who should NOT buy

If you're looking for a shoe that performs well at anything faster than an easy pace, the Cloudsurfer 3 isn't for you. We found it heavy, sluggish, and lacking bounce. Instead, alternative options like the ASICS Novablast 6 or New Balance Ellipse leave it in the dust.

We also believe the Cloudsurfer 3 won't satisfy runners who prefer a soft midsole that lets their feet sink into the foam. If that's what you're after, we recommend the New Balance Fresh Foam X More v6 or Mizuno Neo Vista 3 instead.

Cushioning

Shock absorption

We registered 146 SA at the heel and 120 SA in the forefoot, both strong results for a daily trainer built around relaxed mileage or long runs.

Indeed, heel shock absorption also improved by 6.6% over the Cloudsurfer 2. We welcome that progress, especially for runners who wanted more protection from the series without moving to a different On model.

Energy return

Surreal brings a new foam name, but the rebound upgrade didn't arrive in our tests. We measured just 46.2% energy return in the forefoot and 46.6% at the heel, disappointing results for a shoe introduced with a new supercritical EVA foam and a cocky name.

More concerning, forefoot energy return fell dramatically compared with version 2. We see little reason to choose this midsole specifically for its bounce, despite the strong emphasis on new foam technology.

Heel stack

The Cloudsurfer 3 has moved firmly into max-cushion territory. After cutting the shoe in half, we measured 43.1 mm beneath the heel, making it 14.9% taller than the previous version.

That's a major change in identity for a series that used to sit much closer to the road. We now see a tall daily trainer with generous underfoot material, moving away from the lower-profile construction of earlier models.

Drop

On advertises an 8 mm drop, but our measurements put the Cloudsurfer 3 at 10.9 mm.

That's a steeper setup than the published specification that is better suited to heel strikers than runners choosing the shoe specifically for a moderate or low offset.

Midsole softness

Note: Low measurement: softer. High measurement: firmer.

We've been testing On shoes for a very long time, and we've noticed a recurring theme with its training models: the ride often feels firmer than the brand claims and even firmer than the name suggests.

Although the CloudTec Phase cavities add some softness underfoot, we still found it to be a firm shoe, something our 41.7 AC reading clearly confirmed.

The EVA-based foam also became 24% firmer after our freezer test, revealing a noticeable change in softness when temperatures drop.

Rocker

The side profile reveals a clearly upturned forefoot paired with a very rounded heel bevel. We also noticed how the CloudTec Phase cavities change angle along the sole, matching On's goal of sequential compression from landing through toe-off.

Internal length

Note: Our testing shows that internal length is not a great measure of fit. But, as many users have requested this specific test, we've decided to add it for those interested.

Width / Fit

We measured 95.4 mm across the widest part of the forefoot. The heavily padded upper looks generous, but the internal width sits close to average, giving the shoe a more conventional fit than its bulky appearance implies.

However, it's also important to consider that the warp knit upper has some stretch, adding accommodation around the foot.

Toebox width

The toebox doesn't taper aggressively toward the big toe. Measuring 74.4 mm in our gel replica, we found slightly more room than in the average running shoe.

However, the overall shape remains fairly conventional, and we believe On designed it to accommodate as many runners as possible.

Toebox height

The main fit restriction comes from the limited space above the toes. We measured just 25.6 mm of vertical clearance, an 8.6% reduction compared to the previous version.

This makes the toebox noticeably shallower, although the warp knit upper feels so comfortable and forgiving that we believe most runners are unlikely to experience discomfort from pressure on top of their toes.

Traction / Grip

Traction test

At 0.45 in our traction test, the grip is just decent rather than a standout strength. We wouldn't put this outsole among our first choices for runners who prioritise maximum traction, and we believe that a shoe priced like the Cloudsurfer 3 should score a bit higher.

Outsole design

We found three broad rubber panels covering both sides of the forefoot and heel. Down the centre, a recessed channel exposes a single row of moulded foam protrusions. The overall layout provides good rubber coverage around that channel, with separate forefoot and heel sections following the shape of the midsole.

On Cloudsurfer 3 Outsole design

Flexibility / Stiffness

Even without a Speedboard plate, we still needed 19.8N to bend the sole, requiring 72.2% more force than version 2.

That's a massive departure from the highly-flexible construction of its predecessor, completely changing the underfoot feel and potentially becoming a dealbreaker for some runners. No wonder we found such a pronounced rocker before!

Weight

The Cloudsurfer 3 tipped our scale at 10.7 oz (303g) in a men's US 9, making it a whopping 19.3% heavier than its predecessor. And unsurprisingly, this substantial weight gain could be another dealbreaker for some runners.

On has clearly shifted toward a cushioning-focused daily trainer, combining a max-stack midsole with a super-plush upper. However, the added weight is the most obvious trade-off for this new direction.

Stability

Lateral stability test

There are several details that add structure to this neutral trainer: raised foam sidewalls around the heel and midfoot, a firm rearfoot frame and a platform that spreads farther under the forefoot than before.

However, the Cloudsurfer 3 still has a very tall midsole. For us, it's a stable neutral shoe, but not a shoe that we would recommend for overpronators.

Torsional rigidity

We needed 17.2 Nm of torque in our torsional rigidity test, finding noticeably more resistance than average. The hollow-looking midsole certainly doesn't leave the sole freely twistable!

Heel counter stiffness

We scored the heel counter 4/5 after finding substantial resistance to folding. The thick rolled collar adds padding at the rim, but there's still a firm structure below it.

Runners with sensitive heels should assess that contact carefully, especially around the upper edge of the counter.

Midsole width - forefoot

Across the forefoot platform, we measured 117.1 mm, providing a useful landing area and some flare beyond the upper. It's wider than the previous version, although the increase is modest.

We wouldn't describe this platform as unusually wide for a max-cushioned trainer, which is perfectly in line with On's design philosophy.

Comfort

Breathability

We gave the upper 3/5 in our smoke test, as we confirmed only moderate airflow. Ventilation is clearly not a standout feature, although we think it's a reasonable result for such a thick, pillow-like knit upper.

There are visible ventilation openings in the forefoot, but our microscope images reveal tightly packed yarns and fine fibers partially covering some of these gaps.

Tongue padding

We discovered a mixed lacing layout in the Cloudsurfer 3: flat woven laces pass through textile loops along the midfoot, with reinforced punched eyelets at the top. The extra upper eyelet allows a heel-lock knot, while the soft loops avoid placing rigid, rubbing-prone hardware across most of the instep.

On Cloudsurfer 3 tongue

Padding is anything but minimal. Using our digital callipers, we measured an exceptionally thick tongue at 11.4 mm.

Tongue: gusset type

We spotted no tongue gussets, so neither side is connected to the upper.

A central lace keeper provides an anchor, but we would still prefer side attachments to keep such a bulky tongue centred. It's an odd omission in a shoe that otherwise invests so much material in upper comfort.

Price

Good news first: the On Cloudsurfer 3 retains the same MSRP as its predecessor. We appreciate this price hold, especially considering the added cushioning and more substantial upper construction.

However, we believe the Cloudsurfer 3 offers solid value only for runners who prioritise comfort over pace and faster miles, as its performance feels underwhelming from heel to toe. On the other hand, if you're looking for a comfort-first daily trainer, we think the price is reasonable.
