On Cloudstratus is a running shoe designed to reduce strain, absorb impact, and adapt to your running style. The shoe's CloudTec technology is meant to mimic the feeling of running on clouds, with the midsole made of On Running's Helion superfoam, which combines flexible and rigid elements into one foam compound. This foam is then molded into individual pods underfoot, called CloudTech cushioning. The Cloudstratus also has a thick, engineered mesh upper that wraps around your foot, along with a plush tongue and heel collar for added comfort.
