The Air Jordan 4 Retro ‘Infrared’ features distinctive color blocking that recalls the ‘Green Glow’ AJ4 release from 2013. The upper is crafted from smooth nubuck in a charcoal finish. A lighter shade of grey distinguishes the forefoot overlay, while black accents land on the quarter panel netting, structural wings and Jumpman-branded heel tab. The sneaker’s titular hue lights up the woven tongue tag and a quartet of molded eyelets. A polyurethane midsole packs visible Air-sole cushioning in the heel for a smooth ride
