The Air Jordan 4 Retro GS 'Lightning' 2021 version reintroduces a sought-after 2006 hue in grade school proportions. The mid-top, like the original, has a bright yellow nubuck upper with black moulded eyelets and matching black netting on the quarter panel and throat. The wings, internal tongue, and moulded Jumpman logo on the heel overlay all have dark grey highlights. The braided tongue tag is adorned with a second Jumpman emblem. The shoe is built with a white foam midsole and noticeable Air-sole cushioning in the heel. Underfoot is a gripping herringbone traction pattern on a grey rubber outsole.
