Our Verdict

HOKA Clifton 9

On Cloudmonster 2

The HOKA Clifton 9 and On Cloudmonster 2 are popular daily trainers—perfect if you run mostly for Strava kudos. The On is more stable, noticeably bouncier, and provides more cushioning underfoot. The HOKA, however, is lighter and simpler, offering a smooth ride on casual daily runs. If you prioritize maximum comfort and bounce, choose the On; if weight matters most, the HOKA is your better bet.
