A new concept in fast, breaking barriers and smashing records, the On Cloudboom Strike LightSpray in Bloom/Lime uses a brand-new spray on upper for a precision fit with almost no weight.

The On Cloudboom Strike LightSpray takes the engine room from the proven and successful Cloudboom Strike race shoe. Consisting of their pinnacle foam Helion HF, a pre-shaped Carbon speedboard and cloudtec pods, it offers incredible lightness and propulsion, perfect for making the most of every race event. The upgrade comes in the upper, where On have used revolutionary new technology in the form of a robot arm that over the course of 3 minutes sprays the upper onto a last, or form. Because the arm can precisely place each spray, On can create a precise, seamless and incredibly lightweight upper from 1.5km of thread. At only 30g per upper, the speed benefits are obvious, but by cutting down from over 34 pieces in a traditional shoe to 7, and a 1 step assembly, it is also created with a 75% reduction in carbon emissions. With an adaptive fit the LightSpray offers the ultimate connector of shoe and body, creating speed and agility ready for your new PB.
