On Running Cloudboom Max Running Shoe Women - White/Yellow

The On Running Cloudboom Max women’s marathon running shoe is a premium racing trainer designed for ambitious female marathon runners who want plush cushioning without sacrificing pace. Built for 42.2 km sessions and race-day efforts, it combines dual-layer Helion HF Hyper Foam with a Glass Fiber Speedboard® for a smooth, propulsion-focused ride.

Key Features

• Helion HF Hyper Foam (double layer) – soft landings with energetic rebound; reduces fatigue over marathon distances while keeping propulsion responsive.
• Glass Fiber Speedboard® – reinforced with glass fibres for stiffness and durability, converting impact into forward momentum for powerful toe-offs across running styles.
• Max Cushion platform – high-stack cushioning that prioritises comfort on long runs and race-day endurance without compromising drive or stability.
• Featherlight engineered upper – ultra-light, breathable mesh that minimises weight and adapts to foot swelling for a comfortable, dialled-in fit.
• Cushioned heel and structured upper – secure heel lock and stability at speed, reducing movement during long intervals and marathons.
• Durable rubber outsole – road-focused traction and durability that hold grip at race pace and through tough sessions.
• Race-optimised geometry (8 mm drop) – promotes a smooth, forward-driving stride, aiding cadence and steady pacing over marathon distances.
• Breathable comfort under load – mesh ventilation and a supportive chassis keep feet fresh across high-mileage days.
• Secure midfoot fit – upper construction reduces movement inside the shoe, supporting stability during long, fatigued miles.

Performance Overview

The Cloudboom Max sits firmly at the cushioned, high-performance end of road racing footwear. It prioritises sustained comfort and efficient propulsion over outright top-end speed. Helion HF Hyper Foam and the glass-fibre Speedboard absorb impact while giving a lively toe-off, so you can keep a forward cadence across long miles and stay focused on form and strategy rather than foot fatigue.

In training and racing, the breathable upper and wider, stable platform keep the fit secure as fatigue increases. The 8 mm drop encourages cadence without forcing awkward acceleration or braking, helping preserve energy over the marathon distance. It is particularly well suited to steady, long tempos where consistent pace is the priority, while still feeling responsive when you shift into a lighter gear for the finishing kilometres.

Who Is It For?

• Mid-to-advanced female marathon runners seeking maximum cushioning for long distances without sacrificing pace.
• Runners needing a stable, secure fit for race-day confidence and consistent pacing over 42.2 km.
• Athletes prioritising long-distance comfort, energy return and endurance during high-mileage training blocks.
• Those who value breathable uppers and a supportive, locked-in heel for stability at speed.
• Anyone looking for a performance shoe that combines plush cushioning with an efficient toe-off for marathon-focused workouts.
