On Cloudboom Max - White - Green - Trainers - UK 9

This shoe is ideal for adult male runners aiming to improve their marathon times, particularly those targeting finish times around four hours or more. It offers a balance of cushioning and propulsion suitable for long-distance racing.

The Cloudboom Max uses Helion HF hyper foam, which offers a more forgiving and cushioned feel compared to the stiffer, often less forgiving, ride of a traditional carbon fiber plate. This can lead to greater comfort over long distances for some runners.

While they can be used for some training runs, they are optimized for racing. For maximum lifespan, it's recommended to use them primarily for race day and longer tempo runs, rotating with a more durable trainer for everyday mileage.

The On Cloudboom Max weighs 296g in a men's UK size 8.
