Our Verdict

HOKA Mach 6

On Cloudboom Zone

The HOKA Mach 6 and the On Cloudboom Zone are both lightweight, unplated trainers built for uptempo runs and intervals, but they deliver different sensations underfoot. The Cloudboom Zone is slightly lighter and uses a plastic shank to add some stiffness, paired with a firmer midsole that feels more energetic but also less forgiving. While neither shoe is highly protective, the HOKA feels a bit more cushioned overall, especially in the forefoot.
