On launches the Cloudboom Max

The Cloudboom Max delivers race-day performance designed for dedicated marathon runners targeting a 4:00 to 4:30 hour finish. With max cushioning, a glass-fiber Speedboard®, and a stable, supportive ride, it brings high-performance innovation to runners who train seriously and need comfort over long distances.

The Cloudboom Max joins the Cloudboom family – On’s dedicated race day footwear offering. Whether chasing a personal best or running their first race, the line offers a race day solution for a wide range of goals, needs and paces.

The launch coincides with the Fall/Winter 2025 Pace collection – an edit of bold, expressive running apparel that combines performance with personality. Together, they reflect On’s continued focus on credibility and innovation across all levels of the running journey.
