Description
Flagship On trail supershoe for ultra-distance and mountain running. High-stack, max-cushioned design with a roomy fit. Widely praised for comfort, stability, and accessible ride.
Ride feels soft, stable, and efficient, balancing plush cushioning with responsive turnover. Wide platform and Speedboard plate provide a planted, confident feel on moderate trails. Breathable upper and secure lockdown support long hours of running. Outsole grip and durability are the main limiting factors, especially in wet or technical conditions.
Best for ultra-distance runners seeking comfort and stability on dry, runnable trails and fire roads. Excels in long mountain races and training where protection and fatigue reduction are priorities. Less suited for technical or muddy terrain due to outsole limitations. Remains a top choice for those prioritizing comfort and a forgiving ride over aggressive traction.
