The Cloudboom Max excels for slower-paced, longer-duration running with its high stack, stability, and comfort features. Its excessive stiffness and weight limit daily training and tempo work. Best suited for marathon runners targeting 4+ hour finishes and recovery runs at easy paces.
Ideal for Recreational to intermediate marathoners targeting finish times between 4 and 6 hours who prioritize comfort and stability over speed; runners with wider feet or those seeking a secure, centered platform; heavier runners who benefit from the shoe's robust foam and support structure; athletes transitioning from traditional trainers to super shoe technology who need a forgiving entry point; runners whose form varies during fatigue and who value the shoe's lateral stability and predictable ride characteristics

Upper molds and adjusts to foot movements over long distances. Measured bounce provides energy return without lateral energy loss. Breaks in nicely after initial stiffness. Wide-foot friendly with true-to-size sizing. Best suited for neutral runners seeking maximum cushioning and stability for marathon distances.
Sizing: True-to-size. Designed for neutral runners. Comparable sizing to other On Cloudboom models.
