The most barefoot-like and lightest of the Free family, the Nike Free RN Flyknit 2017 Women's Running Shoe is ideal for short runs. A sock-like upper hugs your feet yet feels barely there, while an innovative sole lets your foot flex and expand naturally. And, their packable design is easy to stash in a tote or backpack—so you can pack in a few miles on the fly.
Flyknit material contours to the shape of your foot for a snug fit. 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.
The Nike Free sole provides the feel of a minimalist running shoe. It moves with you, mimicking the movement of your foot by expanding and contracting with every landing and push-off, for a 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 a smoother, less distracting feel when you bend at the forefoot.
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.
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 the material waste of traditional cut and sew by an average of 60%. The equivalent of six recycled plastic bottles are used in every pair of Flyknit shoes, saving millions of kilos of material from reaching landfills.
