Re-released in August 2019, the AJ 4 Retro 'Cool Grey' celebrates the iconic sneaker's 30th anniversary in a true-to-form retro of a 2004 colorway. The Cool Grey nubuck upper is framed with a white midsole that houses a visible Nike Air unit, while black details line the outsole and lace loops. A hint of Varsity Maize appears on the tongue patch, Air bubble and outsole, while a chrome Jumpman logo adorns the back heel.
