The On Running Cloudflyer delivers both cushioning and support in an ultralight package. The CloudTec® midsole delivers maximum cushioning with minimal weight so the shoe weighs less than 9 ounces. The shoe last has a wider surface to provide a more stable stance. Inside, a dual-density sockliner, plush tongue, and V-molded padded heel cap provide superior comfort. The shoe also features a curved rocker midsole which helps to support the foot's natural rolling motion.
