On Cloudflow 5

The On Cloudflow 5 is built for runners who want a snappy, modern trainer that can comfortably bridge fast intervals and longer tempo efforts. It takes the familiar CloudTec feel and sharpens it with a more performance-focused midsole setup, pairing a lively top layer of Helion HF hyper foam with a propulsive Speedboard to keep turnover quick and efficient. Underfoot, the ride leans firm and responsive rather than plush, making it a strong pick for workouts where you want clear ground feel, stable landings, and a smooth roll into toe-off.
