The first colorway of the LeBron 15 Low EP, known as the 'Supernova', made its debut when LeBron James showcased it at the NBA All-Star Media Day & Practice held during the 2018 NBA All-Star Weekend at the LA Convention Center. This particular colorway, released in April 2018, boasts a University Red, blue, and black BattleKnit upper that provides a comfortable and snug fit reminiscent of a sock. Furthermore, the shoe features black leather heel tabs, a red Swoosh, a speckled grey midsole, red Max Air cushioning integrated into the heel, Zoom Air technology in the forefoot, and an icy blue translucent rubber outsole.
