The Cloudflow is On's tempo shoe — built for the day that isn't easy and isn't race day. The Cloudflow 5 upgrades to Helion HF on top of a glass-fiber-reinforced Speedboard, with a pronounced forefoot rocker; reviewers call it firm and resilient, best the faster you run. The Cloudflow 4 keeps a lighter Helion platform and is the more forgiving of the two at slower paces. Cloudflow 4 Quartz Flame, earlier-generation Cloudflow on standard Helion (not HF), lighter and more forgiving at slower paces than the Cloudflow 5.
