Never Worn Before! Nike Free RN in the color black and white, size 9. Designed for short races and a typically barefoot fit, the Nike Free RN 2018 - woman running shoe is the lightest model of the Free RN family. The upper, enveloping like a glove, integrates more stretch yarns than previous versions for comfort never felt before. The innovative sole, with an updated workmanship, expands and contracts with every movement. Thanks to the "packable" design, the shoe is easy to store in the bag and never give up an out-of-program run.
