The Nike Air Jordan 4 Retro GS 'Infrared' (408452-061) is built in grade school sizing, suitable for boys and girls. The shoe is dressed in a mix of Dark Grey, Cement Grey and Black, accompanied with infrared details on the moulded eyelets and on the woven Jumpman tongue tag. The upper is made from durable nubuck leather with black accents on the quarter panel netting, structural wings and Jumpman-branded heel. A White midsole atop a Grey rubber outsole gives the design a completed look. An exposed Air-sole unit in the heel offers lightweight cushioning, incorporated into the dual-tone midsole of the shoe.
