The 2021 edition of the Air Jordan 4 Retro GS Lightning?? brings back a sought-after 2006 colorway in grade school sizing. Like the original, the mid-top makes use of a bright yellow nubuck upper with black molded eyelets and matching black netting on the quarter panel and throat. Dark grey accents settle on the wings, interior tongue, and molded Jumpman logo on the heel overlay. A second Jumpman icon decorates the woven tongue tag. The sneaker is mounted on a white foam midsole with visible Air-sole cushioning in the heel. A grey rubber outsole features a grippy herringbone traction pattern underfoot.
