The original Air Jordan 6 Retro was released in February 1990, again designed by Hatfield. Some elements were the same from the Air Jordan IV, but the Air Jordan V's most distinctive feature is arguably its reflective tongue. There was also another innovation: clear rubber soles. The soles gave the shoe a whole new and unique look, but it yellowed over time when exposed to moisture. To combat this problem, collectors stored the shoes in a cool, dry place with a desiccant at the soles, most commonly silica. The Air Jordan V also featured a base top with lace locks, making strapping on the shoe easy. The lacelock feature partly inspired the Air Jordan Spiz'ike. The Jordan Retro 5 model is considered to have the best structure and design to wear during basketball games and sold the most pairs of shoes from the Jordan Shoes For Sale. Hatfield is believed to have drawn inspiration for the Air Jordan V from the World War II P-51 Mustang fighter plane; which is most notably visible in the shark teeth shapes on the midsole. The Jordan Retro 6 was retroed in 2000 to great demand, including a new colorway featuring Michael Jordan's high school colors.
