The Air Jordan 4 (IV) Retro - Cool Grey / Chrome - Dark Charcoal - Varsity Maize is one of the nicer colorways in the Air Jordan 4 (IV) line- up. The Air Jordan 4 (IV) was the first Air Jordan shoe to be retroed in never before released colorways! It features a grey upper which is very appealing, along with black and white on the sole, and a yellow air bubble at the heel, probably the most attractive feature.
