If you do enough research, you can find about ten original colorways of the Air Jordan I KO. But, at the end of the day, many are samples that never actually released to the public. Another difference between the AJI and the AJKO is the outsole. For the ‘Silver Anniversary’ of the Air Jordan in 2010, Jordan Brand retroed the KO’s for the first time. Two colorways of the Air Jordan 1 Retro KO High dropped, both original. They featured a ‘vintage’ look to them with yellowed midsoles, ‘powdered outsoles and some yellowing on the uppers as well. The original style outsole was also replaced with the regular AJI version.

One year later, in 2011, the Air Jordan 1 Retro KO High would return. This time around, they featured an entirely different look, with premium leather uppers instead of the traditional canvas. Three colorways dropped and to date, are the only AJKO’s to release with a canvas upper. In 2012 they made another appearance. Three colorways released during this short run, which included the original black/red and ‘Black Toes’ as well as a new Barcelona-inspired pair, which was a part of the ‘Road to the Gold’ Collection.

In 2013, Jordan Brand debuted the Air Jordan 1 Retro High OG. A version featuring original ‘Nike’ branding, just like the versions released in 1985. One year later, the Air Jordan 1 Retro KO High got the ‘OG’ treatment, complete with its original outsole and packaged in an orange Nike box. The original white, red and black colorway returned for its second time, sans the ‘vintage’ look. The original black/royal AJI was converted to an AJKO for the first time and ditched the royal shade for a new sport blue scheme.
