On gives its radical LightSpray super shoe a makeover for spring race season
On’s Cloudboom Strike LS returns in a fresh White/Lime finish
Swiss running shoe brand On is doing things differently – again. Hot on the heels of its carbon-plated podium-hunter, the Cloudboom Strike LS, comes a brand-new limited edition in a crisp White/Lime colourway.
Launching 10 April, the new Cloudboom Strike LS uses LightSpray, On’s bold upper construction method that ditches traditional stitching and layering in favour of a 1.5km filament sprayed directly around the shoe’s last.
The result? A seamless, ultra-light upper that delivers a snug, second-skin fit made in just three minutes.
This isn’t just about looks. LightSpray cuts material waste and reduces carbon emissions by up to 75% compared to On’s other racing uppers.
First seen at the Boston Marathon last year, the Cloudboom Strike LS has already helped elite runners snag course records and top spots – so you know it’s not just a gimmick.
On is keeping this drop tight. The White/Lime edition will only be available through On stores and select run-specialty retailers – perfect for runners who want to nerd out with in-store experts before race day.
And if you're headed to Boston, On Labs will return to the marathon expo (17-22 April 2025) with immersive demos and exclusive try-on opportunities.
