One of Nike's most historic running models, the Cortez, becomes the next silhouette redone in the new sustainable Flyleather that is made with at least 50% leather fiber. Flyleather is lighter, more durable, and has a lower carbon footprint. The mindful take on the Cortez also features 100% recycled lining, laces and labeling. This sustainable version of the style staple is now available in a white-based colorway.
