The Air Jordan 4 Retro GS ‘DIY’ features a look designed to be customized. The shoe’s upper is built with leather, finished in white and contrasted by black throughout, including on the TPU eyelets and structural wings. The vamp includes the usual netting, but the quarter panel forgoes it, instead adding pen-and-ink grapics. Those designs can be filled in using markers, adding color to the look. Underfoot, the lightly speckled midsole houses visible Air in the heel for cushioning.
