The Air Jordan 4 Retro GS 'Lightning' 2021 is a grade-school shoe that brings back a 2006 colorway. Built with nubuck, the shoe's upper appears in Tour Yellow, with the molded eyelets and netting contrasting the look in black. The wings, inside of the tongue and heel branding all add grey to the design, as does the rubber outsole, which provides traction underfoot through its herringbone pattern. The white foam midsole anchors the design, with visible Max Air in the heel included for cushioning.
