The On Running Women's Cloud X 5 Sneaker in Black and White is the brand's do-everything trainer, engineered for workouts that move in more than one direction. CloudTec Phase cushioning compresses in sequence for controlled, responsive landings, while a firmer platform than the road-going Cloud delivers the stability that lifting and lateral work demand. Breathable engineered mesh keeps the upper light, and the secure midfoot hold means no slipping mid-session. The black-and-white colorway keeps it clean enough to wear straight from the studio to the rest of the day.
