Introducing the Cloudboom Strike

At the forefront of the Prism Collection is the Cloudboom Strike, a revolutionary race shoe engineered for marathon excellence. This model features:

  • Marathon Tailored Comfort: One-piece semi-transparent mesh upper, cage system for critical support, molded heel, and constructed tongue for targeted comfort.

Expanding the Boundaries of Track Performance

The Prism Collection also includes:

  • Cloudspike Citius: a track spike designed for power and propulsion with a top-loaded plate that enhances energy return. Optimized with a 23mm forefoot stack height for perfect balance, this spike was crafted in collaboration with On’s top mid-distance athletes and already proven at prototyping in high-ranked races. The minimalist one-piece upper offers strategic support, making it ideal for race day performance.
  • Cloudspike Amplius: a track spike with the comfort of a road shoe. Featuring a maximized stack height and Helion™ HF for optimal energy return, it ensures reduced impact and fresh legs for the final lap. The midfoot shank plate adds stability, while the lightweight, one-piece upper provides comfort and support for long-distance events.
