A pair of trainers worn by basketball legend Michael Jordan fetched US$615 000 at an online auction on Thursday. The Nike Air Jordan 1 High sneakers, described as the “rarest of the rare”, were used by the Chicago Bulls star in an exhibition game in 1985. In total, Christies sold nine pairs of Jordan’s shoes to celebrate his 14-year career with the team. There is a big market for rare trainers and collectors can pay high prices. Jordan is considered to be the best basketball player in the history of the game, and became a global icon in the 1980s and 1990s, helping to raise the NBA’s profile around the world. A recent Netflix series, “The Last Dance,” has renewed interest in his life.
