The On Running Men's Cloud X 5 Sneaker in Black and White is built for the kind of training that changes direction. Where the classic Cloud is tuned for the road, the Cloud X 5 adds lateral stability and a firmer, more connected platform for lifting, intervals, and studio work. CloudTec Phase cushioning rolls through the footstrike in sequence rather than all at once, giving controlled landings without the mushy feel that undermines a heavy set. A breathable engineered mesh upper and secure midfoot hold keep the fit locked in through fast, multi-directional movement. In crisp black and white, it looks as composed on the street as it performs in the gym.
