On Cloudrunner 3 review

We believe that the On Cloudrunner 3 is a fantastic choice for:

• Runners who care more about premium design, comfort, and build quality than lightweight performance or speed-focused training.
• Those searching for a very cozy shoe that works well for walking, daily wear, and occasional easy runs.
• Anyone with mild pronation who want a stable daily trainer that feels supportive without becoming overly-corrective.

We think the On Cloudrunner 3 may disappoint runners searching for a lively and fun stability shoe. During our runs, the combination of the hefty build and low-rebound Helion foam made the ride feel noticeably sluggish, especially compared to energetic rivals like the Saucony Tempus 2 or Adidas Supernova Solution 2.

We also believe the firm midsole will not appeal to runners who prefer a plush underfoot sensation. The Nike Structure Plus offers a more forgiving and pillow-like feel for daily training while keeping a stable ride.

The On Cloudrunner 3 delivered solid shock absorption results in our first lab test, reaching 130 SA in the heel and 107 SA in the forefoot. These are not sky-high numbers, but this shoe was never designed to chase maximum cushioning. Instead, On focused on creating a dependable and versatile daily trainer that also feels comfortable for walking and all-day wear.

We also found that this setup marks a small but noticeable improvement over both the Cloudrunner and Cloudrunner 2.

On kept the same Helion foam for this update, and honestly, we already expected energy return to remain one of the shoe’s weakest areas before even starting our lab tests.

With just 53.2% in the heel and 57.0% in the forefoot, the Cloudrunner 3 once again highlights why we believe On really needs a more modern training foam that feels aligned with 2026 standards rather than 2021.

With 36.8 mm of heel stack height, we think On made the right call by keeping the Cloudrunner 3 within a moderate range instead of chasing the max-stack trend.

Shoes like the Cloudmonster 3 already cover that space, and we believe there is still a huge group of runners who prefer a more approachable, stable, and everyday-friendly design like this one.

The forefoot follows the same design philosophy as the heel, although it starts flirting with max-stack territory by packing a substantial 28.7 mm of cushioning underfoot.

On lowered the drop in the Cloudrunner 3 to create a more universal and comfortable ride that works better for a wider range of runners beyond just heel strikers. As a result, we measured an actual heel-to-toe offset of 8.1 mm.

During our runs, we found that the On Cloudrunner 3 retains the familiar firm ride that defines most On running shoes. For newcomers to the brand, that may feel confusing at first since the word "Cloud" and the CloudTec tech probaly suggest a plush experience.

However, this shoe sits in the firm-riding category with a measured softness of 43.6 AC. The hollow CloudTec channels may create a slightly softer sensation underfoot, but make no mistake, this is not a soft shoe. Still, given its stability-focused mission, we actually think this firmer tuning works very well here.

The rocker also shows a very noticeable evolution compared to version 2, now featuring a much more aggressive heel-to-toe curvature.

The rearfoot redesign makes perfect sense given the lower drop, while the early rocker start point of the forefoot should work especially well for runners dealing with hallux rigidus or a very stiff big toe.

We used the interior of the Cloudrunner 3 as a mold, filling it with gel and letting it cool so we could capture the exact shape and take precise fit measurements.

In our first reading, we found that the Cloudrunner 3 delivers an average-width fit at 95.5 mm.

In our second fit measurement, we found that the toebox narrows down to just 71.0 mm. From a stability standpoint, this more restrictive shape makes sense, but runners who prefer extra room for toe splay may not enjoy this design.

We also found that the Cloudrunner 3 runs slightly low in terms of toebox height at 25.2 mm.

It never felt uncomfortable during our runs, but there is definitely less vertical room for the toes compared to many other daily trainers.

We tested the On Cloudrunner 3 using the exact same protocol we apply to every shoe in our lab, and the result was genuinely solid.

Its 0.68 traction score marks a meaningful upgrade over the previous version and also ensures dependable grip when the roads turn wet, so rainy-day runs should not be a problem at all.

The outsole receives a full redesign that increases rubber coverage while also widening the central cutout.

The new layout feels more aggressive, smoother, and noticeably less clunky underfoot, yet it still preserves the unmistakable On DNA that makes the brand’s outsoles instantly recognizable.

In our 30-degree stiffness test, we found the Cloudrunner 3 ranking extremely high with a substantial 19.3N result. It's even a bit more than what we were expecting!

We really liked that On reduced the weight with version 2 and managed to move the Cloudrunner in a better direction.

That’s why we’re disappointed to see version 3 gaining weight again and essentially returning to square one. At 10.5 oz or 298g, it feels heavy and highlights the urgent need for a lighter, more modern supercritical foam.

We noticed from our very first run in the On Cloudrunner 3 that comfort was clearly the top priority behind this design, although that approach also comes with a few compromises.

One of them is breathability, as we found the shoe less ventilated than we initially expected. During our smoke test, only a limited amount of airflow managed to escape through the upper and we gave it a 2 out of 5.

Once we placed the engineered mesh over our portable LED light, we quickly confirmed that On intentionally prioritized structure and support over maximum airflow. Very little light was able to pass through the material.

Using our digital microscope, we also discovered that even the visible ventilation holes are backed by a secondary inner layer that improves comfort and durability while noticeably restricting airflow.

From a material quality and construction standpoint, the upper feels amazing and impressively well-built. However, we think it will perform best for runners who can avoid extremely hot and humid climates.

It’s very clear to us that On put a huge amount of effort into making the Cloudrunner 3 as stable as possible, especially for heel strikers.

The decoupled heel geometry, TPU heel clip, firm Helion foam, and broad platform all work together to create one of the most stable and confidence-inspiring rides currently available.

We found the Cloudrunner 3 to be exceptionally rigid, scoring a massive 19.0 Nm in our torsional rigidity test. That result sits far above the current average and even surpasses many carbon-plated shoes, which, as we already mentioned, plays a major role in the shoe’s ultra-stable ride.

We gave the heel counter a 4/5 in our stiffness assessment, clearly above the current average. That result was hardly surprising for a stability shoe, especially one built with so much structure and reinforcement around the rearfoot.

We found the On Cloudrunner 3 slightly bulkier than its predecessor overall, although that change does not really extend to the forefoot area.

Our calipers measured 118.3 mm in the forefoot, which sits above the current average yet remains almost identical to the result we recorded in the Cloudrunner 2.

However, the heel is where On clearly expanded the platform, and that’s also the main reason why the Cloudrunner 3 feels noticeably bulkier overall. We measured a broad 97.8 mm in this area, and we also found that the midfoot comes with a wider-than-before design focused heavily on stability.

The toebox delivered a solid 3/5 durability score in our testing. While that may sound average on paper, achieving this result is actually quite impressive for a road shoe that uses such a soft and comfort-focused upper material.

The Cloudrunner 3 feels incredibly comfortable around the heel, but we discovered that this plush setup comes with a durability trade-off. In our Dremel test, it managed only a disappointing 2 out of 5.

After attacking the outsole with our Dremel, we measured only a tiny 0.6 mm dent. That’s an excellent result!

After grabbing our calipers once again and measuring the outsole at 3.4 mm, combined with the strong result from our durability test, we genuinely believe that early outsole wear should be virtually impossible for most runners here.

We measured the stock insole at 4.4 mm thick inside the Cloudrunner 3.

The insole is not glued down at all, so swapping it for a third-party option is incredibly easy if needed. However, we would recommend choosing one with equal or lower thickness, as the toebox does not offer especially generous vertical space.

Helion may not be the most energetic foam on the market, but it performs impressively well in cold conditions. After spending 20 minutes inside our freezer, it became only 12% firmer, which is an excellent result for maintaining a consistent underfoot feel in winter weather.

Outstanding job here from On, although we honestly expected nothing less. The Swiss brand consistently ranks among the best when it comes to integrating reflective details, and the Cloudrunner 3 once again proves that point.

On’s designers clearly understand that many people will end up using the Cloudrunner 3 as much for walking as for running, and we found that it performs exceptionally well as an all-day comfort shoe.

The tongue perfectly reflects that comfort-focused approach, featuring a thick 7.2 mm padding setup that extends through most of its length and does a fantastic job protecting the instep from unwanted lace pressure.

Some brands skip gusseted tongues in their daily trainers to reduce costs and simplify production, but On clearly chose not to cut corners here.

The heel combines soft padding, a sculpted collar, and a flared design to create an exceptionally comfortable and secure rearfoot fit. And as it happens with most On shoes, there's no heel tab at all.

On is a brand widely known for charging premium prices, and the Cloudrunner 3 certainly isn’t cheap either. However, we think this is one of the company’s most compelling models from a value perspective, especially for runners prioritizing comfort, stability, and all-day support over outright performance.
