On Cloudboom Max All

The all-black treatment strips the Cloudboom Max back to the shape itself, which is no bad thing for a shoe that sells on how it behaves rather than how it looks. Underneath the plain upper sits On's marathon platform: a high, springy midsole with a carbon plate set into it, designed to keep a pace honest for hours.

It is the shoe for the race you have trained all season for, plus the two or three long workouts where you want to know exactly how that pace will feel. Cushioning stays effective well past the point where a flatter racer would feel harsh, and the geometry encourages a quick, rolling transition at the front of the foot.
