A nearly seamless upper hugs your foot yet feels barely there, while the revolutionary outsole lets your foot move the way it's meant to. The easily packable construction lets you run freely anywhere you go. A one-piece Flyknit upper conforms to the shape of your foot for a snug feel. Integrating breathability throughout the top, support on the arch and stretch on the outside of the foot, the Flyknit is ultra-comfortable. The incredibly flexible Nike Free sole moves with you, mimicking the movement of your foot by expanding and contracting with every landing and push-off, for a freeing, natural feel. Strong yet feather-light Flywire cables work with the laces to provide more support as you tighten them. A set of cables has been removed from the top lace to allow for more flexibility and a smoother, less distracting feel.
