POISED FOR ACTION.

The Cloudboom Strike 2 was designed to deliver race-day speed for marathons and half marathons while keeping feet comfortable and supported. Lightweight yet responsive, it helps you maintain endurance from start to finish.

CloudTec Sphere™ is On's latest cushioning system, featuring thin gaps between the forefoot and the midfoot.
