Shaft measures approximately Low-Top" from arch
FOOT-HUGGING FIT. Flyknit material conforms to the shape of your foot for a snug feel. Combining breathability throughout the top, support in the toe and stretch on the outside of the foot, the Flyknit material helps keep your foot cool during your run.
NATURAL MOVEMENT. 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.
ULTRA-LIGHT SUPPORT. 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.
Single seam on the inside of the heel for a smooth feel.
Heel is rounded to roll with the ground on heel strike.
NATURALLY FLEXIBLE. The Nike Free RN Flyknit 2017 Men's Running Shoe features a nearly seamless design that hugs your foot yet feels barely there, while the sole lets your foot move naturally. The easily packable construction lets you bring your shoes with you anywhere you go.
