Redesigned to tackle the elements, the Nike Wmns Free RN 2018 Shield packages weatherized protection for the modern runner. This 'Oil Grey' women's iteration combines stretchy textile, a woven water-repellent material and synthetic overlays with reflective elements on the seamless upper. A pink heel puts a feminine spin on the sporty look. A toggle lacing system quickly adjusts in cold, wet conditions. Signature tri-star tread completes the rubber outsole.
