TLDR: The White/Black On Cloudboom Max is a high-performance marathon shoe with dual Helion™ HF Hyperfoam cushioning, a fibreglass Speedboard® and a breathable mesh upper. It will be available on 14 August 2025 for €240. It was developed for ambitious marathon runners who value maximum energy return and high comfort. The double layer of Helion™ HF Hyperfoam ensures a soft landing and explosive propulsion, while the integrated fibreglass Speedboard® efficiently propels you forward with every step. The lightweight, breathable mesh upper adapts perfectly to the foot over time and provides an almost weightless feel. Reinforced heel cushioning reduces impact, which makes all the difference, especially over long distances. The grippy rubber outsole provides secure traction on asphalt – whether in training or on race day. Weighing just 296 g and with an 8 mm drop, the Cloudboom Max is perfect for marathons lasting over 4 hours.
