# Robot-Built Running Shoes LightSpray Cloudmonster 3 Hyper Uses Automated Spray-On Upper By Amy Duong | Published 2026-03-01 | Fashion Source: Trend Hunter, https://www.trendhunter.com/trends/lightspray-cloudmonster-3 References: [on](https://www.on.com/en-us/products/cloudmonster-3-hyper-ls-u-3ug1001/unisex/limelight-bloom-shoes-3UG10014837)  The new [LightSpray](https://www.trendhunter.com/trends/on-lightspray-cloudboom-strike-2) [Cloudmonster 3 Hyper](https://www.trendhunter.com/trends/lightspray-cloudmonster-3-hyper) is a performance running shoe from Swiss brand On that uses robotic manufacturing to form its upper in a continuous process. A robotic arm sprays a single filament of material onto a foot-shaped mold, creating a seamless upper in about three minutes without seams, laces, or glue and bonding it directly to the midsole through thermal fusing. The shoe is constructed from just eight components, a significant reduction compared with typical running shoes that are assembled from dozens of pieces. The design pairs the sprayed upper with a thick Helion HF hyper-foam midsole set on [CloudTec](https://www.trendhunter.com/trends/loewe-x-on-lightspray-cloudmonster) cushioning geometry to provide light support for long runs. Weighing about 205 grams for a men’s size US 8.5, the shoe is lighter than the standard Cloudmonster 3 model.
