The On Cloud X is a lightweight, versatile performance running shoe engineered for speed, agility, and all-day comfort. Featuring On’s signature CloudTec® sole with hollowed-out cloud elements that compress on impact and rebound during toe-off, it delivers exceptional cushioning and energy return. The upper combines breathable black mesh with supportive synthetic overlays and a reinforced heel counter, while the Swiss-engineered construction ensures durability and precise fit. A low-profile, responsive ride makes it ideal for interval training, gym workouts, and urban commuting. The sleek monochrome design—black upper with crisp white midsole and subtle gray accents—exudes modern minimalism, complemented by the iconic 'On' logo on the side and Swiss flag detail at the heel. Lightweight (approx. 230g per shoe), flexible, and highly breathable, it transitions effortlessly from track to street. Perfect for runners seeking a fast, agile shoe with premium comfort and refined aesthetics.
