In 2005, Nike unveiled the Nike Free RN, a groundbreaking running shoe that drew inspiration from track runners who preferred to train without footwear. Fast forward to the Free RN Flyknit 2017 'Oreo' version, the upper of this shoe is crafted from Nike's innovative Flyknit fabric, which was introduced seven years after the original release. Known for its flexibility and breathability, Flyknit delivers a comfortable fit. The bottom of the shoe features the iconic Nike Free sole, designed to expand and contract with the foot, providing a natural and cushioned stride.
