Cloudflow 4
Cloudflow 4 is a lightweight trainer for tempo runs, speed sessions and road racing. Dual-density Helion and CloudTec sandwich a spoon-shaped nylon-blend Speedboard for fast, forward-rolling rides. A closed midsole channel limits stone pickup, while rubber pads add traction and durability on wet and dry roads. Its woven upper uses a recycled-polyester base, and revised heel construction improves comfort and lockdown.
