Weighing just 278g, the CLOUDFLOW 5  is engineered for speed and responsiveness. 
A layer of Helion™ HF delivers maximum energy return and rebound, while the propulsive Speedboard®—crafted from a glass fiber and nylon blend—supports powerful transitions. 
The breathable woven mesh upper ensures ultralight comfort, and the extreme rocker shape promotes a fast, forward-rolling stride. 
With a redesigned toebox for quicker sessions and enhanced forefoot grip for added stability during toe-off, the shoe draws design inspiration from ON's race-winning super shoe line.
