On Cloudboom Strike - Women's 

Built for marathons. Race-day ready. This road runner is ultra-responsive, ultra-cushioned and part of the Prism Capsule Collection.

Cushioned Bounceboard
Made using ultra-responsive Helion™ HF hyper foam, the shoe’s innovative Bounceboard construction propels you forward with power. A removable layer of plush cushioning, it maximizes energy return for a bouncy feeling underfoot – all while abiding by stack height regulations. A cushioned ride, ideal for long races.

Carbon fiber Speedboard®
The stiff, spoon-shaped Speedboard® works like a spring, absorbing energy and transferring it into the forefoot for the most powerful take-offs possible. And strategically-placed CloudTec® elements create a faster, smoother roll-through. The result? Increased running efficiency.

Ultralight upper
Ultralight and breathable, the one-piece, semi-transparent mesh upper helps to reduce overheating. The cage-like construction locks down the midfoot for a secure, race-ready fit.
