The Prism Capsule Collection shoe built for marathons and half marathons. Ultra-responsive and cushioned, it’s ideal for long-distance road races.

The innovative Bounceboard midsole in responsive Helion™ HF drives you forward with conviction. It’s an ultra-soft, removable layer that maximises energy return and adds bounce, while staying within stack height regulations. For a cushioned stride, perfect for the longest races.

Structured Speedboard®

Made of carbon fibre and “spoon” shaped, this shoe’s structured Speedboard® is a spring: it absorbs energy and transfers it to the forefoot for an ultra-powerful toe-off. Strategically placed CloudTec® elements create a fast, smooth roll-through for a more efficient run.

Ultralight upper

Breathable and feather-light because it’s made from a single piece of semi-transparent mesh, the Cloudboom Strike’s upper helps reduce overheating. The “cage” structure locks the midfoot in place for a secure fit, ideal for racing.
