On Cloudboom Strike 2

The second generation of On's carbon-plated marathon racer, keeping the tall Helion HF PEBA stack and aggressive rocker of the original. Expect small refinements to the upper and geometry rather than a rework. Still a snug-fitting shoe aimed at efficient racers.

Who it's for

Reach for the On Cloudboom Strike 2 for race day and tempo days and intervals. It's a neutral shoe, best for runners with an efficient stride who don't need pronation support. The tall, soft stack favors comfort over ground feel. That's great for high mileage and bigger runners, less so for racing snappiness.
