While running finally ramps up the production of “hyper-foam” spray shoes.

Swiss shoe company On – one of the fastest growing shoe brands – has done very well for itself, growing into a company A $3 billion company On the soles of his giant inflated shoes. Today the company announced three new kicks and the opening of a new production plant in South Korea that will produce many, many more — at least that’s the goal.

Specifically, the company is focusing on producing its latest and weirdest shoe, a giant laceless running shoe with a sole with a one-piece toe box made of “ultra-foam” plastic that is sprayed by robot arms. The plastic is made of 40 percent bio-foam, and the shoe is made of just eight pieces; On says his minimalist approach saves the shoes’ carbon footprint.

The LightSpray Cloudmonster 3 Hyper is a change from the first On shoe to use toe box spray technology, Cloudboom Strike LS. Besides the addition of LightSpray branding to the product, the main difference is the switch to the Cloudmonster model, which, in shoe tradition, tends to offer more comfortable soles. This new version has 20% more foam, for all the runners who love a squishy bounce. They will have a limited release on the company’s website and retail stores in North America starting March 5, with a global expansion on April 16.

The new LightSpray boots weigh 205 grams apiece (less than half a pound), making them slightly heavier than the 170-gram Cloudboom Strikes. It’s also cheaper at $280 versus the Cloudboom’s higher price of $330.

While WIRED I like First iteration Of the LightSpray shoes, no one else, except a few select marathon runners, has had the opportunity to use them. Production runs were very limited, and shoes were expensive. Now, On has boosted its production in South Korea, enabling it to expand its overall production of LightSpray shoes by 30-fold in 2026.

On says her goal is to expand LightSpray’s efforts to appeal to a broader audience of runners beyond just elite athletes. The company has plans to launch other LightSpray products later this year.

Whether laceless or slip-on shoes will find their footing in the shoe market is not yet a winning idea. While brands like Nike offer slip-on shoes, laceless fastening tends to be reserved for one-off shoes like Back to the Future II-Inspired Adaptation BP Self-lacing shoes. Some serious runners prefer to seek out the natural run offered by shoes with a thin sole, such as Barefoot shoesbut On still doubles down on its double-sized pillows. People seem to be loving them, as On is also announcing two other Cloudmonster shoes. One is the laced Cloudmonster 3, and the other is the regular Cloudmonster 3 Hyper with laces and a non-LightSprayed toe box. (Ah, laces. How outdated.)

Aon says it has another strategic goal of increasing its global production of LightSpray shoes, “within the next few years.”
