With a re-engineered upper to prevent warping, creasing, and scuffing, the wider toe box ensures a more comfortable fit, and firmer side panels provide added stability. The durable foam midsole with the iconic wedge insert allows for all-day wear, while the herringbone outsole pattern combines durability with heritage style. Originally designed in 1972 by Nike co-founder Bill Bowerman, the Cortez was created to be lighter and more comfortable than any other shoe, quickly becoming the most popular running shoe in the U.S. and cementing its place as an iconic part of pop culture.
