On Cloud 5 Review: Swiss Engineering Meets Everyday Comfort
There are running shoes, there are lifestyle shoes, and then there are shoes that somehow nail both without compromising either. The On Cloud 5 falls squarely into that last category — and that’s exactly why you see them everywhere from airport terminals to trail heads.
On Running, the Swiss brand founded in 2010 by former Ironman champion Olivier Bernhard, built its entire identity around one idea: running should feel like flying. Their patented CloudTec sole technology uses hollow “cloud” pods that compress on impact and spring back, creating a sensation that’s genuinely unlike any other shoe on the market.
After months of daily use — running, walking, traveling — here’s the full breakdown.
CloudTec Technology: How It Works
The sole consists of individual cloud-shaped pods made from zero-gravity foam. Each pod compresses independently on landing, absorbing impact vertically, then locks together at toe-off to create a rigid platform for push-off. The result: soft landing, explosive take-off.
The Cloud 5 uses On’s Speedboard — a rigid plate sandwiched between the midsole and outsole that stores and releases energy with each stride. It’s not carbon fiber (that’s reserved for the Cloudboom), but it provides noticeable snap that cheaper foam shoes lack entirely.
The channel between pods also helps with drainage — water runs through rather than pooling under your foot. Not waterproof, but quick-drying.
Design and Build Quality
Materials and Construction
The upper uses engineered mesh with welded reinforcements at stress points. No unnecessary overlays, no decorative stitching that’ll come undone after 200km. The tongue is lightly padded and stays centered during runs — a small detail that matters enormously on longer efforts.
The heel counter provides structure without rigidity. You get locked-in stability without the “cast” feeling that some stability shoes create.
Weight and Dimensions
| Spec | Men’s | Women’s |
|---|---|---|
| Weight | 232g (US 9) | 198g (US 7) |
| Stack height | 28mm heel / 22mm forefoot | |
| Drop | 6mm | 6mm |
| Lacing | Speed lacing + conventional |
The speed lacing system is polarizing — some love the slip-on convenience, others swap immediately for traditional laces (included in the box). For daily wear, speed laces are brilliant. For serious running where micro-adjustments matter, swap them out.
Comfort and Fit
Sizing
On Cloud 5 runs true to size for most foot shapes. Wide-foot runners should size up half a size — the midfoot is slightly narrower than competitors like Nike Pegasus or New Balance Fresh Foam. The toe box is adequate but not spacious.
Break-In Period
Essentially none. The Cloud 5 feels comfortable from the first step. The midsole doesn’t need “softening” like traditional EVA foams because the cloud pods are already at their optimal compression point out of the box.
All-Day Wear
This is where the Cloud 5 genuinely excels. Standing all day at a conference? Walking 25,000 steps through a new city? The energy return from the Speedboard means your legs feel noticeably fresher at the end of the day compared to flat-soled casual shoes. This isn’t marketing speak — it’s a measurable difference in fatigue.
Running Performance
Road Running
For easy runs and moderate-effort sessions up to 15km, the Cloud 5 performs well. The cushioning is responsive without being mushy, and the 6mm drop encourages a midfoot strike without forcing it. Ground feel is better than maximalist shoes while still providing adequate protection on hard surfaces.
Where It Falls Short
The Cloud 5 is not a racing shoe. It’s not a long-distance marathon trainer. Above 15km or at tempo paces, runners who want more cushion should look at the Cloudmonster or Cloudstratus. For speed work, the Cloudflow is lighter and more responsive.
Grip and Outsole
The rubber outsole provides good grip on dry surfaces and acceptable traction on wet pavement. It’s not a trail shoe — if you need off-road capability, On makes the Cloudventure for that. The cloud pods do collect small stones occasionally, but they pop out easily.
Durability
After 500+ kilometers, the midsole retains about 80% of its original cushioning feel. The outsole rubber wears evenly for neutral strikers. Heel-strikers will see faster wear on the rear pods — this is normal for any shoe but more visible on the Cloud 5 due to the pod design.
The upper mesh held up well — no holes, no separation at seams, no delamination of the welded overlays. The speed laces show slight fraying at the cord tips around 400km but remain functional.
Expected lifespan: 600-800km for running use, longer if primarily walking/daily wear.
On Cloud 5 vs. Cloudmonster vs. Cloudflow
| Feature | On Cloud 5 | On Cloudmonster | On Cloudflow 4 |
|---|---|---|---|
| Weight | 232g | 275g | 238g |
| Stack height | 28mm | 35mm | 26mm |
| Best for | Daily / casual + easy runs | Max cushion / long distance | Tempo runs / racing |
| Drop | 6mm | 6mm | 6mm |
| CloudTec pods | Standard | CloudTec Phase (double layer) | CloudTec |
| Speedboard | Standard | Full-length | Full-length |
| Price | ~$150 | ~$170 | ~$160 |
Quick verdict: Cloud 5 if you want ONE shoe for everything. Cloudmonster if you run 40+ km/week and need maximum cushion. Cloudflow if you race or do speed sessions.
Pros and Cons
Pros:
- Unique CloudTec cushioning genuinely delivers on the “soft landing, firm take-off” promise
- Extremely comfortable for all-day wear and travel
- No break-in period — ready from day one
- Lightweight at 232g
- Quick-drying drainage channel in sole
- Speed laces + traditional laces both included
- Clean, minimal aesthetic that pairs with anything
Cons:
- Narrow midfoot may not suit wide feet
- Speed lacing system not ideal for precision fit during intense running
- Cloud pods collect small stones on gravel paths
- Not enough cushion for marathon distances (get Cloudmonster instead)
- Premium price point (~$150) for what’s essentially a daily trainer
- Outsole durability slightly below Nike/ASICS equivalents
Who Should Buy the On Cloud 5?
Perfect for you if:
- You want one shoe that handles daily wear AND casual running
- You travel frequently and need a comfortable, versatile shoe
- You run 3-4 times per week at easy to moderate effort
- You prioritize lightweight comfort over maximum cushion
- You appreciate clean design that works with casual and athletic outfits
Look elsewhere if:
- You run marathon distances regularly (Cloudmonster or ASICS Gel-Nimbus)
- You have wide feet and need a roomier fit (New Balance Fresh Foam, Nike Pegasus Wide)
- You run on trails (On Cloudventure or Salomon Speedcross)
- Budget is tight (plenty of solid options at $80-100 from ASICS, Saucony)
Conclusion
The On Cloud 5 isn’t trying to be the fastest racing shoe or the plushest recovery shoe — it’s trying to be the best all-around daily shoe for active people, and it succeeds convincingly. The CloudTec technology delivers a genuinely distinct feel that justifies the premium over generic foam runners.
If your shoe needs span from morning runs to office wear to weekend travel, this is the one-shoe solution that actually works without compromise in any direction. The Swiss engineering isn’t just marketing — it’s in every detail of the construction, from the drainage channels to the welded-mesh upper to the Speedboard energy return.
Worth the $150? If you’ll wear them daily, absolutely. The cost-per-wear math works out quickly when a shoe handles everything.
