NIKE AIR JORDAN 1 KO "CHICAGO" WHITE/BLACK-UNIVERSITY RED DA9089-100 Nike Air Jordan 1 KO White/Black-University Red Brand new, unused Jordan 1 KO. Deadstock. Size: 29 cm There is a stain on the toe of the right foot. Please check the photos. The original retail price in Japan for the "AIR JORDAN 1" released in 1985 was 17,800 yen. Because it was expensive at the time, the "AJ KO (AIR JORDAN 1 KO)" was released as a more affordable version, using canvas instead of leather. To reduce costs, the sole unit of the "NIKE VANDAL," which was on sale at the time, was used instead of the regular "AIR JORDAN 1" sole. By the way, the price of "AJ KO" at that time was 6,800 yen. Two colors, white x red x black and red x black, were also released in Japan. Due to the small number of sales at the time, it was a phantom model that was traded at high prices in the vintage market of the 1990s. This time, it is a re-release of the original color. It is the fourth appearance, following the original in 1986, the vintage processed retro (402297-101) in 2010, and the retro (638471-101) in 2014. Released in May 2021, the Japanese retail price was 17,050 yen.
