On Cloudrunner 3 Is a Stability Daily Trainer for Runners Who Don't Want a Full Stability Shoe

What it is

The On Cloudrunner 3 is the third generation of On's stability-focused daily trainer. It sits between On's neutral Cloud X 3 and the full-stability Cloudrunner Waterproof. The Cloudrunner 3 targets runners who need some additional heel stability during easy jogs and walking without committing to a dedicated stability shoe with firmer medial posts. Under the hood is On's signature Cloudtec cushioning foam, a Speedboard plate for forward energy transition, and a reinforced heel collar. Weight is roughly 10 oz for US men's 9.

Pricing is $159.95 US / £140 UK from On direct and authorized retailers.

What's interesting

Stability-adjacent without the stability-shoe weight is the category On is carving out. Traditional stability shoes (Brooks Adrenaline GTS, Saucony Guide) add medial posts that firm up the midsole under the arch, but also add weight and rigidity. The Cloudrunner 3 provides supplemental heel stability through structural design rather than firm foam, keeping the shoe lighter and more flexible while still helping runners who mildly over-pronate.

Doctors of Running specifically framed the Cloudrunner 3 as a "pick for runners that need some additional stability in the heel, but do not want a full blown stability shoe." For the growing population of casual runners and walkers with minor pronation tendencies, this positioning hits a real market gap.

Cloudtec foam is On's signature. The individual rubber "clouds" on the outsole compress under landing impact and rebound to assist push-off. For long easy runs and walking, the cushioning is noticeably softer than Asics Gel-class foam at similar weight.

Generation 3 refinements over the Cloudrunner 2: smoother transition from heel strike to forefoot push, redesigned heel collar that better locks the foot, and an updated engineered mesh upper with more ventilation for warm-weather running.

At $159.95, the Cloudrunner 3 sits in the mid-tier pricing band alongside the Hoka Arahi 7 and Brooks Adrenaline GTS 24, which is the category On is competing in.

What's missing or unverified

The Speedboard plate is not as aggressive as the carbon-plate racing shoes. For tempo runs or races where energy return matters, the Cloudrunner 3 is fine but not competitive with the Nike Vaporfly or Saucony Endorphin Speed. This is not a racing shoe.

Stability is described as "additional heel support" rather than traditional medial-post stability. Runners with significant over-pronation will still need a dedicated stability shoe. The Cloudrunner 3 targets mild-pronation runners only.

At 10 oz, the shoe is typical weight for its category but not the lightest. Carbon-plate marathon shoes (Asics Metaspeed Sky+) hit 7-8 oz; the Cloudrunner 3 is not that tier.

On's Cloudtec foam is comfortable but can feel inconsistent on uneven surfaces. RTINGS noted the cushioning works best on flat roads and lighter trails; for technical trail running, a true trail shoe is the right pick.

Durability of the engineered mesh upper is average. Running Warehouse reviews show roughly 300-400 miles of useful life before the upper shows visible wear, which is typical for the category but below Nike Infinity Run.

Who it's for

Casual runners with mild over-pronation who find dedicated stability shoes too firm or too rigid. Walkers and joggers covering 15-30 miles per week on roads. Trainers for new runners building up to half-marathon distance who want supportive cushioning without the marathon-race firmness.

Not for: serious racers (carbon-plate shoes are the answer), true trail runners (get the Cloudventure), severe over-pronators (Brooks Adrenaline GTS or Asics Gel-Kayano is the right tier).

Verdict

The On Cloudrunner 3 at $159.95 is the right daily trainer for mild-pronation runners who want supportive cushioning without the weight of traditional stability shoes. Cloudtec foam, Speedboard plate, and the updated heel collar all work together for easy-effort runs and walks. Against the Brooks Adrenaline GTS 24 and Hoka Arahi 7, the Cloudrunner 3 wins on weight and flexibility; it loses on aggressive stability support for severe pronators. For the target runner, this is the right pick.
