The Nike React Infinity Run is the lastest evolution of the Epic React. This shoe is the essential part of Nike's new effort to develop a shoe that will prevent running injuries. To do so, they have used 24% more React foam in the midsole of the Infinity Run than in the previous Epic React. They have also widened the midsole to provide greater stability without including any posting in the shoe. Designers also developed a rocker geometry that more closely mirrors the design of the Vaporfly Next% to create a more fluid transition from heel to toe. It appears that smooth, soft, and stable is the key to avoiding running injuries. For those who noticed that the orginal Epic React's outsole tended to wear too quickly, Nike has included more rubber on the outsole for much better durability, The Nike React Infinity Run is part of Nike's efforts to make running more comfortable by rethinking running shoe technology. Be part of the future and try the React Infinity Run.
