Elevate your run with a blend of supreme support and comfort. The ON CloudFlyer 5 has been re-engineered, with every update geared towards creating a smoother ride, so you are able to get more from your daily and longer runs. An updated broader platform at the heel is complimented by the new dual density Helion Superfoam, which is firmer in the heel for protected landings, and softer in the forefoot for smoother toe-offs. For additional security, a moulded heel clip and plush heel padding provide a secure lockdown with every stride.
