Recommend half or one size up. The Nike Cortez is the first track shoe released by Nike in 1972, which was designed by Nike co-founder Bill Bowerman,an Olympic-class track coach, who felt that athletes needed a comfortable and durable running shoe designed for distance training and road running. As an homage to the base silhouette’s original colorway, sacai has dressed their Cortez 4.0 in “White,” “Varsity Red,” and “Varsity Royal.” The shoe’s exterior even mirrors the OG in its construction, opting for leather through the profile and suede across the toe cap and eye stays. The heel, sole unit, and top line, in contrast, feature the Japanese label’s signature touch: the counter is comprised of multiple layers, the bottom is brutalist similar to previous collabs, and the ankle is further cushioned thanks to the addition of a second, blue-dominant collar.
