Propulsive Marathon Performance with Responsive Cushioning
The On Cloudboom Max is engineered for marathon training and long-distance road performance. Featuring CloudTec® cushioning and a double layer of Helion™ HF hyper foam, this high-performance shoe delivers powerful energy return with sustained comfort across extended mileage.
Who This Shoe Is For
The Cloudboom Max is best suited to neutral runners preparing for half marathon and marathon distances. It performs well during long runs, tempo sessions and structured marathon build phases where propulsion and cushioning efficiency are critical.
When This Shoe Makes Sense
This model is ideal for runners who want a plated, performance-driven shoe for marathon training without moving into an ultra-light race-only model. If you are targeting sustained pace over distance and want structured propulsion with impact protection, the Cloudboom Max provides a balanced race-ready platform.
Why Runners Choose the Cloudboom Max
The CloudTec® cushioning system is engineered for a fast and fluid ride. Two layers of Helion™ HF hyper foam increase energy return while maintaining long-distance comfort. A glass fibre-infused Speedboard® enhances propulsion and running efficiency without excessive rigidity. The lightweight mesh upper adapts to foot movement over long efforts, while the padded heel design enhances comfort deep into marathon-distance training.

Frequently Asked Questions – On Cloudboom Max
Is the Cloudboom Max a race-day shoe?
Yes. The Cloudboom Max is designed for marathon-distance performance and can be used on race day. It offers propulsion and energy return while maintaining more structure and cushioning than ultra-light super shoes.
Does it have a carbon plate?
The Cloudboom Max features a glass fibre-infused Speedboard® rather than a full carbon plate. This provides forward propulsion and efficiency while feeling slightly less aggressive and more stable than traditional carbon-plated racers.
Can I train in this shoe weekly?
Yes. Unlike ultra-light race-only shoes, the Cloudboom Max is built with durability and cushioning suitable for long runs, tempo sessions and marathon build phases.
How does it compare to a super shoe?
Super shoes prioritise minimal weight and aggressive propulsion. The Cloudboom Max delivers strong energy return but with slightly more cushioning stability and durability, making it more versatile for training.
Is it stable enough for the full marathon distance?
Yes. The dual-layer Helion™ HF foam and structured geometry provide cushioning protection and control across extended mileage, making it suitable for sustained marathon pacing.
