Built for runners who train fast and race faster, the Cloudflow 4 is our top pick for speed-focused road work. CloudTec cushioning paired with a Helion superfoam midsole gives you a responsive, lightweight ride that doesn't beat you up over miles. At 8.3 oz with an 8mm drop, it balances agility and protection without compromise.
- CloudTec cushioning pods compress on impact and snap back for explosive toe-offs — soft landing, energetic push-off
- Helion superfoam midsole returns energy efficiently without adding weight, keeping the shoe under 8.3 oz
- Engineered mesh upper breathes well in heat and humidity while conforming to your foot for a secure, adaptive fit
- 8mm heel-to-toe drop and 26mm heel stack suit tempo runs, race days, and high-mileage training blocks equally well
- Speedboard construction channels energy forward through your stride, reducing fatigue on longer efforts
