Marathon Sports On Running Men's Cloudboom Strike

An Ultra-Responsive and Ultra-Cushioned Racing Shoe

The On Cloudboom Strike is a unique road racing shoe that’s built to excel in the marathon distance. Crafted with ultra-responsive Helion™ HF hyper foam and an innovative drop-in midsole called a Bounceboard, this design helps maximize energy return while offering a bouncy underfoot feel, perfect for longer races.

A stiff, spoon-shaped carbon-fiber Speedboard® within the midsole works as a spring to absorb energy and transfer it back to the forefoot, creating powerful take-offs. You’ll also find On CloudTec® elements strategically placed to aid in faster, smoother transitions, helping to increase your overall running efficiency.
