Nike Free has been tested and developed for over 15 years. Barefoot running can increase the volume and power of the muscles in your feet. In general, better muscle coordination lets you better absorb impacts on each landing and reuse the energy spent.

The Free series consists of only two models, the RN 5.0 and RN Flyknit 3.0. In 2021, around 10 years after the first release in 2011, the Free Run 2 was available again.

Though you can wear socks with the Nike Free Flyknit, the intent is that you don't. The upper has been engineered to conform to your foot and feel like a sock.
