The Air Jordan 4 Retro 'Cool Grey' re-released in August 2019 to celebrate the sneaker's 30th anniversary, with its original 2004 colorway. The Cool Grey nubuck upper is paired with a white midsole, which accommodates a visible Nike Air unit for extra comfort. Black accents are used for the outsole and lace loops, and Varsity Maize pops up for the tongue patch, air bubble, and outsole.
