The Cloudstratus 3 is On’s cushioned daily trainer built around “dual‑layer cushioning and stable propulsion.” It’s well‑suited for medium‑ to high‑weight runners doing long‑distance training and recovery runs. The midsole uses dual‑layer Helion™ super‑foam combined with CloudTec® cloud modules to deliver soft shock absorption and stable support. The Speedboard™ propulsion plate is made from a nylon‑blend material, enhancing gait smoothness and the rolling sensation. The upper is an engineered mesh made from 100% recycled polyester, offering strong breathability, while the updated lining and tongue improve comfort and lockdown. Overall, the ride is plush, soft‑bouncy, and stable — ideal for heel‑strikers and mid‑foot strikers training from 5K up to the marathon, as well as for everyday wear. If you’re looking for a running shoe with dual‑layer cushioning, stable support, and sustainable materials, the Cloudstratus 3 is one of the most balanced options in the On lineup.
