The women’s Free RN Motion Flyknit 2017 boasts a lightweight knit upper in basic black, offering a snug, virtually seamless fit that runs from the ankle-length collar to the toe. A unique strap system in matching black provides added support, adorned with a small white Swoosh. A four-way stretch strap connects to the upper for enhanced flexibility, while the Nike Free outsole in contrasting white delivers a natural range of motion.
