Product details

The On Cloudsurfer 2 is a running shoe designed for female athletes, available in white and size 37.5. This successor to the original Cloudsurfer features On's proprietary CloudTec cushioning system, which consists of individual cloud elements that compress under load to provide responsive cushioning and a smooth transition throughout the running cycle. The shoe incorporates Speedboard technology that works in conjunction with the CloudTec elements to propel the runner forward with each step. The upper is made from technical mesh material, offering breathability and a secure, adaptive fit, with reinforced areas in high-stress zones for increased durability. The outsole utilizes a combination of rubber compounds in strategic zones to ensure reliable traction on various surfaces while maintaining flexibility. The midsole geometry promotes a natural foot movement pattern, and the heel-to-toe drop is approximately 8 mm, supporting a midfoot or forefoot running style. The shoe weighs about 250 grams per shoe in size 37.5, making it suitable for daily training runs and longer distances where consistent cushioning and energy return are priorities. The internal construction includes a comfortable insole and a seamless lining to minimize potential irritation during extended wear. The design maintains On's signature aesthetic with visible cloud elements along the midsole while providing the technical features expected from performance running shoes. This model represents an evolution of the brand's cushioning technology, focusing on delivering a balanced running experience that combines comfort with responsive performance features.
