The Air Jordan Retro 13 Flint French Blue University Blue Flint Grey November 2010 were released on March 19, 2005. They are very similar to the Air Jordan 13 Original - Flints (Navy / Carolina Blue - Flint Grey - White), but feature a lighter blue. These are actually one of the more popular colorways of the Air Jordan 13 (XIII), and is a color scheme seen on many pairs of Air Jordans, as they go very well together. They are also highly sought after because besides looking really nice, they do not feature official team colors, making them adored by Jordan fanatics. The inner lining also features the french blue color scheme to match with the upper, and the tongue is almost totally perforated, which acts a ventilation system.
