The Cloudrunner 3 is On's steady everyday trainer, and On labels its ride stable rather than neutral. The base is wider than before, an asymmetrical heel clip wraps the rearfoot, and Helion foam under the CloudTec elements takes the impact.
It suits you if you want your daily shoe to hold you steady and get on with On's firm, rolling feel — recovery days, steady weekday miles, the long run you want to finish rather than race. If a physio has diagnosed a gait problem, try it alongside a proper stability trainer, not instead of one.
It is not a corrective shoe — the support comes from the shape of the base and heel rather than a firmer wedge under the arch — and it is not fast. At 311 g it is a heavy trainer, and nothing in it is trying to make you quicker.
