The Epic React Flyknit Classic Cortez was released in May 2019 to honor one of Nike's earliest running silhouettes. In red, white and blue, this sneaker puts the OG Cortez colorway on a modern running profile, and "Blue Ribbon Sports Track Club" is printed at the heel tab—a nod to the company that would one day become Nike. A lightweight, one-piece Flyknit construction and data-informed React foam midsole are designed for durable flexibility and optimal energy return.
