Free Flyknit 4.0 'Electric Green'

With a one-piece woven Flyknit upper and deep hexagonal flex grooves underfoot, the Nike Free Flyknit 4.0 'Electric Green' is designed for a nearly weightless feel and the sensation of running in bare feet. The strong yet lightweight Flywire cables create a customized fit, since they integrate with the laces to lock in the foot according to comfort level and tightness preference. A rib-knit collar is durable and snug, and wider-gauge woven mesh at the toe box and sides helps increase ventilation.
