The Air Jordan 4 Retro Infrared (GS) is built on a dark grey nubuck upper with black accents on the quarter panel netting, structural wings, and Jumpman-branded heel piece. Sitting atop the dark grey base is a lighter shade of grey forefoot overlay, while touches of Infrared appear on the molded eyelets and woven Jumpman tongue tag. Lightweight cushioning arrives via an exposed Air-sole unit nestled in the heel of the two-tone midsole.
