The Nike Wmns Free RN 2018 Shield undergoes a seasonal transformation in this latest edition. With its water-repellent upper, the 'Cool Grey' women's version of this dynamic runner ensures moisture is kept at bay thanks to sealed seams and synthetic overlays. To enhance visibility during low-light conditions, the shoe incorporates reflective elements, while the toggle lacing system allows for quick adjustments in cold and wet weather. Additionally, the rubber outsole features the iconic tri-star tread, enabling the foot to splay naturally for optimal comfort and flexibility.
