The On Cloud X is a lightweight, versatile performance running shoe engineered for speed and agility. Featuring On’s signature CloudTec® sole with hollowed-out cloud elements for responsive cushioning and explosive take-offs, it delivers exceptional energy return while maintaining a minimal, race-ready profile. The upper combines breathable black engineered mesh with reinforced synthetic overlays for structure and durability, while the heel counter includes a Swiss flag and 'Swiss Engineering' text—highlighting the brand’s precision heritage. A sleek black-and-white colorway enhances its modern aesthetic, suitable for both training and urban wear. The sock-like fit ensures comfort during high-intensity workouts or daily commutes. Ideal for runners seeking a fast, flexible shoe that transitions seamlessly from track to street, the Cloud X excels in tempo runs, interval training, and light trail use. Its low-stack height (6mm drop) promotes natural foot movement, and the rubber outsole provides reliable grip on varied surfaces. Perfect for fitness enthusiasts who value innovation, comfort, and minimalist design without compromising performance.
