Hellen Obiri’s stunning victory at the 2025 TCS New York City Marathon wasn’t just a testament to her relentless dedication but also to the cutting-edge technology she trusted beneath her feet. The two-time champion, who had already claimed the title in 2022, set a new course record with a finish time of 2:19:51, shattering the 22-year-old record held by compatriot Margaret Okayo. What made Obiri’s achievement even more remarkable was the innovative racing shoe that propelled her to victory: the On Cloudboom Strike LS.
The Cloudboom Strike LS, a revolutionary model from On, the Swiss sportswear brand, is a prime example of the future of marathon footwear. Designed with advanced technology and an ultra-lightweight structure, the shoe features a carbon-plated sole for maximum energy return, a hallmark of the “super shoe” category. This technology has redefined marathon running, enabling athletes like Obiri to push their limits on race day.
What sets the Cloudboom Strike LS apart is its unique “spray-on” upper, a result of On’s innovative LightSpray technology. Instead of using traditional glue or stitching, the shoe’s breathable, form-fitting upper is created by spraying a single filament in an automated, high-precision process. This creates a seamless, laceless mesh that molds perfectly to the runner’s foot, providing unparalleled comfort and fit.
Obiri’s choice of footwear also highlights the growing trend of bespoke, high-performance running shoes. The Cloudboom Strike LS is manufactured in limited quantities, with each pair made one at a time in On’s Zurich-based lab. Due to this meticulous production process, the shoe is not only a high-tech marvel but also comes with a premium price tag, retailing at around $330. Limited drops and specialty retailers make the shoe a coveted item for both serious athletes and enthusiasts alike.
For those looking to own a piece of the future of marathon footwear, the Cloudboom Strike LS has been released in exclusive colorways, including the White/Flame and White/Lime options. With ongoing releases slated throughout 2025, it’s clear that Obiri’s record-breaking run isn’t just a victory for the athlete but also for the technology that supports her. As this cutting-edge gear continues to evolve, it raises the bar for marathon running shoes, offering a glimpse of what the next generation of champions will be wearing.
