The Nike Free RN 2018 is a women's running shoe designed with short runs and sprints in mind. This colorway has a two-toned grey upper, a Crimson Pulse Swoosh on the side panel, and a white sole. A spandex mesh provides a sock-like fit. An elastic band wraps each heel for additional support as well. The Nike Free RN 2019 sits atop a flexible Free midsole with textured tread patterns placed at the toe and heel for improved traction.
