On Running Deploys Spray-On Upper Technology in Cloudmonster 3, Bypassing Cut-and-Sew Assembly

On Running's LightSpray Cloudmonster 3 Hyper deposits polymer directly onto a 3D last, eliminating traditional stitching and adhesive bonding. The process creates a monolithic upper that distributes load more uniformly while reducing component count and material waste. Spray manufacturing demands specialized equipment and real-time process control—a capital-intensive shift that could enable reshoring as labor costs rise in traditional production regions.
