In 1972, it put unprecedented cushioning under the fastest feet in the running world and quickly became the most popular training shoe in the USA. It was an unmistakable icon—a walking billboard that told your story and declared your affiliation—and came to thrive with fierce style on the streets of Los Angeles. Since then, no shoe has expanded the definition of a running shoe quite like the Nike Cortez.
