Inspired by the barefooted training routines of competitive athletes, Nike's Free 3.0 Flyknit was developed to yield a natural running experience. A high-energy color palette drapes the upper of this 'Electric Green' iteration, with a restrained melange scheme at the collar and toe. While Flywire cables improve security, the sockliner molds to the underfoot. Flexibility and grip are enabled by hexagonal grooves and rubber nodes at the sole.
