Released in August 2019 to help celebrate the 30th anniversary of the silhouette, the Air Jordan 4 Retro 'Cool Grey' 2019 brings back a 2004 colorway. The shoe's nubuck upper appears in Cool Grey, with Dark Charcoal providing a complement on the signature eyelets. The tongue sports a Flight tag with a hit of Varsity Maize, while underfoot, a white midsole houses a visible Air unit in the heel. The rubber outsole underfoot includes a herringbone traction pattern.
