Start your running routine every day with the trusted stability and comfort of the On Cloudboom Max. The perfect all-around running shoe for your daily runs. Experience the ultimate performance of the Cloudboom Max, day after day.
Midsole
The Cloudboom Max features a modern midsole made of the ultra-soft Helion™ HyperFoam manufactured by Pebax®. This high-performance foam provides excellent cushioning and a high degree of energy return, allowing you to maintain your speed while running. The foam is combined with the unique CloudTec® technology. CloudTec® are the 'clouds' that absorb shock both horizontally and vertically, making your landing extra soft. As soon as your feet hit the ground, the Clouds stay firmly in place so you can continue with a powerful push-off. Additionally, the midsole incorporates the signature Speedboard®, a plastic plate that flexes during running and provides a responsive feel upon push-off.
Upperwork
The upper is made of Swiss-engineered mesh. Thanks to the breathability of the upper, your feet remain comfortable. Furthermore, the upper consists of recycled materials. In this way, among others, On tries to make its products increasingly sustainable.
Outsole
The shoe features a rubber outsole, providing good grip and traction while running. Buy the On Cloudboom Max now and set new personal records, delivered to your home within a few days!
