The On Running Cloudboom Max Women’s Marathon Running Shoe is engineered for ultra-long distances, delivering maximum cushioning, explosive energy return, and a stable, efficient ride. Built for dedicated marathon runners seeking comfort, endurance, and race-day performance, it combines plush cushioning with a responsive feel that doesn't compromise speed.

Key Features

• Helion HF Double-Layer Foam — dual-layer cushioning delivers ultra-soft landings with energetic rebound, designed for long-distance comfort over 42.2 km and reduced fatigue without sacrificing responsiveness.
• Glass Fiber Speedboard® — reinforced with glass fibers for enhanced stiffness and durability, converting impact into forward momentum for powerful toe-offs and improved efficiency across all running styles.
• Max Cushion Platform — high-stack cushioning provides marathon-ready comfort, delivering a stable yet responsive ride ideal for long training runs and race-day endurance.
• Featherlight Engineered Upper — ultra-light mesh keeps the shoe breathable and adaptable, reducing weight while allowing the upper to flex with foot swelling during prolonged efforts.
• Cushioned Heel & Structured Upper — secure, locked-in heel support minimizes movement at speed, enhancing overall stability and comfort during long intervals and races.
• Durable Rubber Outsole — road-focused traction and durability that maintain grip and stability at race pace and through tough training sessions.
• Race-Optimised Geometry — 8mm heel-to-toe drop promotes a smooth, forward-driving stride, aiding cadence and consistent pacing over marathon distances.
