£120 The cushioning pods (‘clouds’) on the bottom of the shoe is the hallmark of all the models from this Swiss brand. They might look odd but they do the trick. The idea is that they compress on impact to dissipate shock, briefly lock together to provide a stable platform and then spring apart to help push your foot off the floor quicker. Our testers loved the controlled bounce and perceived energy return they provided – something ON has improved from previous versions by making the clouds from foam rather than rubber. Elsewhere, the light, snug upper was a delight for slim-footed runners and has also been given an antimicrobial treatment to stop nasty niffs over time. A brilliant neutral option for short-to-medium distances.
