Overview
- Limited pairs arrive in North America on March 5 via On’s website and retail stores, with full global availability on April 16 at $280.
- The trainer uses eight components including a fully 3D-printed upper and a two-piece Helion HF supercritical foam midsole.
- On cites 40 percent biofoam content in the sprayed-on plastics and claims the minimalist build lowers the shoe’s carbon footprint.
- Cushioning increases with 20 percent more foam than the earlier LightSpray racing model to target everyday runners seeking more softness.
- Output scales roughly 30-fold with 32 robots in South Korea plus four in Zurich, as On positions LightSpray for a broader audience; reported weights vary between 190 grams and 205 grams.
