Next in our On shoes review is the Cloud, an uptempo trainer that at 7.9 ounces is just barely heavier than the Cloudracer. If you think you would prefer a moderate version of the On ride, with a softer heel and firmer forefoot, similar to the Cloudcruiser but with less contrast than the Cloudster or Cloudsurfer, the On Cloud is an attractive option for faster road running or interval workouts.
