Ideal for Neutral runners who want a light, highly cushioned trainer for long runs and tempo work, and who like On's rockered ride and a laceless, sock-like upper. Best for those willing to pay a premium for low weight and comfort.
Long Distance shoes in NORMA's database last between 300 and 900 km across 71 models. At 560 km, the On Lightspray Cloudmonster 3 Hyper sits in the lower half of that range.
The LightSpray Cloudmonster 3 Hyper is On's lightest Cloudmonster, a plateless super trainer built around Helion HF hyper foam and a 45mm-heel CloudTec platform with a laceless LightSpray upper. At just 205g it pairs max cushioning with a responsive, propulsive ride aimed at long runs and tempo efforts. The minimal eight-piece construction keeps weight low and, per On, cuts its carbon footprint. Marketed as a do-most trainer that leans toward faster and longer, it slots between the softer Cloudmonster 3 daily trainer and a dedicated racer. Note these are pre-launch/brand sources, so real-world durability and long-term fit remain unproven, and the price is steep.
