Highlights
- Super trainer with race DNA Built as a daily super trainer, the Cloudflow 5 Lumos borrows race-day tech for tempo runs, threshold sessions, and fast commutes. A dual-layer Helion HF midsole balances light cushioning with a firmer, energetic feel, so you get responsiveness without going full marathon-plated overkill. It is the shoe you grab when the plan says “comfortably hard” and your brain says “let’s send it.”
- Helion HF and Speedboard propulsion Underfoot, a layer of Helion HF supercritical foam delivers max energy return and rebound, helping every stride pop off the ground. A glass-fiber infused nylon Speedboard channels that energy into a smooth, rolling transition, making uptempo paces feel addictive. The 6 - 8 mm style drop and sculpted rocker geometry keep you leaning forward, stacking small speed gains over every kilometer without feeling forced.
- Lumos reflectivity and light upper The engineered woven mesh upper is ultra-light and breathable, inspired by On’s pinnacle race shoes for that barely-there feel on foot. Lumos reflective detailing hits key zones so you stand out under headlights and city glow. Lightweight materials, recycled fabrics, and smart patterning keep the fit secure yet minimal, ideal for long tempo blocks, late-night strides, or all-season run-commutes.
