Our Verdict

On Cloudsurfer 2

On Cloudsurfer Max

The On Cloudsurfer 2 and the On Cloudsurfer Max share the same family name, but they have a few differences. The Cloudsurfer 2 is a lower-stacked, lighter daily trainer that emphasizes smooth transitions and a controlled ride rather than cushioning or energy return. Its Helion foam and CloudTec Phase geometry deliver a firm, stable, and predictable feel that works best for easy to moderate daily mileage, especially if you value guidance and a clean rocker over bounce. The Cloudsurfer Max takes that same concept and stretches it by adding significantly more stack (and weight in the process). While it's marketed as a maximalist shoe, it doesn't deliver an ultra-plush ride either, prioritizing smooth roll-through and stability over softness or rebound.
