Per Nike: The Nike Free Run 2 SneakerBoot combines the barefoot-like benefits of Nike Free technology with a winter boot height. The deep flex grooves of the Nike Free 5.0 sole and the molded sockliner allow for an optimum range of motion. A full inner sleeve construction covers the ankle for sock-like comfort, while a reflective underlay and color-blocking on the heel make this unique shoe even more eye-catching. Photos: EU Kicks
