The Air Jordan 4 (IV) Retro 1999 - Black / Black - Cool Grey are true classics in the Air Jordan 4 (IV) line-up. They feature an all black upper constructed from a soft leather, with perforations on the sides fore breathing purposes. The most noticeable feature of the shoe is the grey portions along the midsole which are speckled with black paint, which is a real nice touch. Other than that, these are really simple, but are still adored by Air Jordan fanatics.
