The Cloudflow 4’s cushioning is slightly softer and more responsive than a typical daily trainer. Landings don’t feel mushy like “cloud‑soft max‑cushion shoes,” but they’re not firm either. 👉 As beginners develop a more stable running form, they’ll feel a gentle forward push on short runs — not a sudden, explosive bounce, but a smooth, subtle assist.

The Cloudflow 4 is On’s lightweight, speed‑oriented trainer designed for tempo runs and interval workouts from 5K up to half‑marathon distances. Its midsole uses a sandwich‑layered Helion™ Superfoam, with a softer top layer and firmer bottom layer, and a Speedboard™ up‑curved TPU plate embedded in between to deliver smooth rockered transitions and stable propulsion.
The upper uses the same woven material found on the Cloudboom Echo 3, offering lightweight breathability, while the padded collar enhances comfort and stability. The outsole features a closed‑pattern rubber design that provides excellent traction on wet surfaces.
Overall, the ride is light, responsive, and stable—ideal for midfoot or forefoot strikers doing speed workouts or racing short to mid‑distance events. If you’re looking for a speed trainer with strong propulsion, stable support, and great value, the Cloudflow 4 is one of the best options within the On lineup.
