User Review Summary
The On LightSpray Cloudboom Strike 2 (June 2026) is On's flagship carbon racing shoe, pioneering the revolutionary LightSpray robot-sprayed seamless upper for record-breaking ultralight weight, built for elite runners chasing personal bests. A full-length Helion HF supercritical foam midsole with a Speedboard carbon plate delivers top-level propulsion and high energy return; the new Cloudtec Sphere forefoot provides a wide, plush landing platform that pushes off smoothly. A 34mm forefoot / 39mm heel stack with a 5mm drop is a racing setup favoring forefoot propulsion and quick rolling. The LightSpray seamless upper is extremely light, snug and breathable. The lightweight durable rubber outsole ensures racing grip. At only about 191g (standard) and NT$9,500, it's one of the lightest premium racers on the market — the ultimate race-day weapon for elite athletes.
