About
What it is.
Cloudultra 2 belongs to On's trail-running range, built around long-distance and ultramarathon terrain rather than road miles. The upper is a knitted sock construction in recycled polyester, meant to seal out debris while staying breathable across a full day on the trail. Underneath, a softer Helion superfoam midsole works with a TPU Speedboard to cushion impact and return energy on rocky or root-covered ground, while CloudTec cushioning handles the repeated pounding of extended efforts.
The outsole carries On's Missiongrip rubber with a revised stud layout for grip on loose or uneven surfaces. As a package, it's aimed at runners tackling variable terrain over many hours, where fit security, underfoot protection, and traction matter more than pace on pavement.
The verdict
The Cloudultra 2 ranks #22 for trail running but excels as a versatile daily wearer with strong cushioning and comfort; however, buyers report inconsistent fit and limited support on rough terrain, making it better suited for roads and travel than serious off-road use.

AI summary of 5 reviews · as of Sep 2026
Reviewers see the Cloudultra 2 as a comfortable, easier-to-wear update to the original, praising its softer cushioning and improved fit while noting the outsole grip and lace-lock feature still draw mixed reactions.
What they praise
- Softer, more compliant midsole cushioning than the previous version
- New knitted sock-like upper is far easier to get on and more comfortable
- Fit issues from the earlier model (narrow, short) have been corrected, now running true to size
- Good all-round grip and stability on mixed or hard-packed trail surfaces
- Breathable upper that also works well as a hiking shoe
What they knock
- Outsole lugs are shallow, so it struggles in mud or very sloppy trail conditions
- The flip-lock lacing expansion feature is widely seen as a gimmick few actually use
- Cushioning is described as firmer than expected for a shoe billed as maximum cushion
- Some reviewers question whether the added cost is justified

You want capable trail shoes without overspending on premium branding.
Mid-range price with strong 4.4/5 rating and solid owner-reported comfort, support, and versatility covers the essentials well for the cost.
You need shoes that work straight out of the box with no fuss.
High comfort and fit ratings, versatile across road/trail/travel, and no complex setup required—ready to wear immediately.
You want a proven, low-risk shoe with broad consensus and established trust.
103 ratings show solid consensus, On is an established brand, and the product has settled into the market with consistent owner feedback.
You love gear that delights beyond specs—design, feel, and sensory appeal matter.
Owner data highlights strong design aesthetics and high comfort/cushioning praise; the shoe earns enthusiasm beyond pure function.
You demand objectively top-tier performance across every dimension.
Mid-tier brand confidence and mid-rated support/durability aspects fall short of best-in-class; higher-tier alternatives exist. Consider Tecton X 3.
You seek prestige and flagship positioning from an established maker.
On is respected but Cloudultra 2 is a mid-range offering, not a flagship; lacks the premium brand cachet or positioning. Consider Akasha II.

Frequently asked
What buyers want to know.
What is the On Cloudultra 2 best for?
Buyers rate it highest for travel and daily wear, with strong marks for cushioning, comfort, and design. It works well on pavement and for gym, walking, and running in everyday settings. Reviewers note it excels as a versatile daily wearer rather than a serious off-road shoe.
Does it work on trails or rough terrain?
Buyers report it lacks structural support on uneven ground and dirt trails, with feet moving around inside due to its airy, flexible design. One buyer found the sides and top don't provide enough foot containment for trail use. It's better suited for roads and travel.
What do buyers say about the fit?
Buyers praise the comfort and describe it as roomy, but there are fit inconsistencies across pairs. Some find it roomier than expected, which works for summer but may not suit buyers who need a snug, structured fit.
How does the cushioning feel?
Buyers rate cushioning highly and report the shoe performs well on daily walks without a break-in period. The airy material provides comfort for travel and warm-weather wear.
How does it hold up with heavy use?
One long-term owner reported wearing their first pair through enough walking and running across multiple trips that the sole wore out, then immediately repurchased the Cloudultra 2 and was satisfied with its performance on daily 10km walks.
