The Air Jordan 4 Retro 'Infrared' features subtle color blocking reminiscent of the AJ4 'Green Glow' release from 2013. The upper is constructed from soft nubuck in a charcoal finish. A lighter shade of gray highlights the forefoot overlay, while black accents land on the mesh quarter panel, structural wings and Jumpman branding on the heel. The sneaker's title hue illuminates the woven tongue tag and a quartet of molded eyelets. A polyurethane midsole features visible heel air cushioning for a smooth ride.
