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 5, Helion HF top layer on an 8% glass-fiber-infused nylon Speedboard, pronounced forefoot rocker. More propulsive at tempo than the Cloudflow 4, ~278 g M9.
