LightSpray™
LightSpray™ is an ultralight technology revolutionising how we move. In just three minutes, a robot creates a precision-engineered, one-piece upper with a seamless, distraction-free fit. Less waste. Lower emissions. Lighter than humanly possible.

The LightSpray Cloudboom Strike is the first On racing shoe made with LightSpray™ technology. It features an ultra-thin, seamless and lace-free LightSpray™ upper, which is precision-sprayed for support. The result is in an exceptionally lightweight shoe weighing just 170g. Check out the product here.
The making of a conventional running shoe upper usually consists of several process steps: raw material production, yarn creation, textile formation (e.g., weaving or knitting), preparation, coloration, additional finishing, cutting and then assembly through bonding and sewing. Every step involves energy consumption, logistics and the creation of waste from materials and water. LightSpray™ represents a breakthrough in footwear manufacturing. It began at On Labs in Zurich, where an independent LCA conducted by Vaayu showed a potential 75% reduction in carbon emissions compared to other On racing shoes. As we scale the technology at our production facility in Korea - now home to more than 30 robots - we continue to see this impact. When producing the LightSprayCloudmonster 3 Hyper at our Korea facility, use of our LightSpray™ technology potentially reduces the carbon emissions related to upper production by 65%, compared to other On racing shoes. All emissions data is based on independent LCAs conducted by Vaayu. You can find more details in the final report from On Labs Zurich here and the latest results from our Korea facility here.

The LightSpray™ upper on the LightSpray Cloudboom Strike is not currently made with recycled materials. But we'll continue to explore ways to incorporate recycled materials as the technology advances.
In manufacturing anything, the most energy-intensive step is generating heat. With LightSpray™, heat is only needed to melt the polymer. But we've cut out all the other processes that require heat in traditional manufacturing, reducing overall energy consumption.
This is a real breakthrough. But it's just the beginning. Watch this space.

You can stretch the collar slightly to slip it on, but the textile-like material wraps your foot for a secure, locked-in feel. Unlike other sock-like shoes that use stretchy, elastic knit textiles, LightSpray™ gets its flexibility entirely from the unique looping of the yarn itself.
The LightSpray™ robot controls the exact thickness of the upper by adjusting the tightness and overlap of the filament loops. For example, the material is thicker around the heel to lock you in, while remaining thin and flexible across the instep. This means you get the support you want exactly where you need it.
We would recommend wearing socks. There's no lining in a LightSpray™ shoe, you stand directly on the foam, so you may want the additional layer.
