The Nike Cortez, first envisioned by Bill Bowerman in 1972 as a durable long-distance running shoe, initially featured a leather upper and later introduced nylon variations. The Nylon Prem QS version, which was part of the 'Quilted Pack' released in September 2013, builds upon the original design by incorporating diamond-shaped stitching on its nylon upper in a striking Squadron Blue hue. The shoe also boasts a dual-density foam sole for enhanced cushioning and a herringbone-treaded sole for improved traction.
