On Cloudboom Strike

The On Cloudboom Strike is a race-day supershoe built to make long-distance running feel smoother, faster, and more efficient. Underfoot, it pairs On’s ultra-responsive Helion HF hyper foam with a unique drop-in Bounceboard that adds a plush, energetic layer directly above the plate for a more connected, springy ride. A spoon-shaped carbon Speedboard helps convert that cushioning into forward drive, while subtle CloudTec elements keep transitions quick and controlled when you’re pressing the pace.
