The On Running Cloud X 4 'Black Eclipse' (2024) represents the latest evolution of On’s versatile training franchise, engineered for athletes who demand stability, agility, and all-day comfort from a single silhouette. Designed in Switzerland and refined through athlete feedback, the Cloud X 4 builds on the brand’s reputation for lightweight performance footwear. The 'Black Eclipse' colourway delivers a sleek, understated finish, pairing deep black tones with subtle contrast detailing for a streamlined, gym-to-street aesthetic that aligns with On’s performance-first philosophy.

The On Running Cloud X 4 is constructed with a breathable engineered mesh upper made with a high percentage of recycled polyester, reflecting On’s continued focus on more responsible material choices. The updated X-shaped Speedboard® is engineered to enhance forefoot flexibility for multi-directional movements, making it suitable for mixed training sessions, short runs, and functional workouts. Underfoot, Helion™ superfoam combines with the brand’s signature CloudTec® cushioning system to deliver responsive impact absorption and stable landings. The midfoot cage construction provides lateral support during dynamic movements, while the rubber outsole is strategically patterned for traction across gym floors and urban surfaces. In the 'Black Eclipse' edition, the monochromatic palette reinforces the model’s modern, performance-driven identity while offering everyday versatility.
