Free technology from Nike has represented a revolutionary albeit simple technology concept which has sought to improve on the current wonders of human foot anatomy. By using a flexible sole with sipes to mimic the foots natural movement it has allowed the development of a stronger foot. Despite the performance beginnings of the Free sole, we’ve seen the tech represented over numerous lifestyle releases including these latest Hybrid Boot NDs. Available in three different colors, styles include both leather and suede uppers with minimal highlights and woven heels. Available at select Nike dealers in early September.
