Details

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.

Foot-Hugging Fit

Flyknit material contours 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.

Ultralight 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.

Nike Free Origins

After learning that Stanford athletes had been training barefoot, three of Nike's most innovative and creative employees set out to develop a shoe that felt natural and weightless, similar to bare feet. The team spent four years studying the biomechanics of runners' feet in motion. The results yielded a profound understanding of the foot's natural landing angle, pressure and toe position, allowing Nike designers to build an unconventional and flexible running shoe from the inside out.

Flyknit Origins

Nike Flyknit technology was inspired by feedback from runners craving a shoe with the snug (and virtually unnoticed) fit of a sock. Nike embarked on a four-year mission with teams of programmers, engineers and designers to create the technology needed to make the knit upper with static properties for structure and durability. Then the precise placement of support, flexibility and breathability—all in one layer—was refined. The result is a featherweight, form-fitting and virtually seamless upper. This unprecedented precision maximises performance while reducing material waste by an average of 60% compared to traditional cut and sew, saving millions of kilograms of material from reaching landfills.
