Air Jordan Collezione 20/3 This is arguable the most desired out of any of the Jordan Countdown Packs. All of the Countdown Packs include two pairs of Air Jordans that add up to equal "23," Jordan's jersey number. This pack includes the Air Jordan III and the Air Jordan XX. The black cement AJ III is one of the most sought after sneakers ever created. It has not been retroed since 2001, that's why many have been anxiously anticipating this release. The AJ XX is also a highly revered basketball sneaker and it's never looked better than in this exclusive black colorway.
