Details

LIGHTWEIGHT AND FLEXIBLE

With an innovative lightweight sole that made it a favourite, the Nike Free RN 2017 Men's Running Shoe weighs even less than before. It also features an updated knit material for a more comfortable fit. The shoe is easy to pack so you can bring it with you anywhere you go.

Breathable

Designed to breath at the top of your foot, it helps you stay cool from your first mile to the last. A thinner tongue and soft, single-layer knit material sit close to your foot for a closer fit.

Secure Fit

Flywire technology—strong, lightweight cables—works with the laces for more support the tighter you lace them. This upgrade has one less set of cables to allow for more flexibility.

Natural Movement

Designed to move with you, the incredibly flexible Nike Free sole mimics the natural movement of your foot by expanding and contracting with every landing and push-off.

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.
