Air Jordan 4 Retro ‘Blue Thunder’ features familiar color blocking that recalls the coveted ‘Thunder’ colorway. The mid-top sports a black nubuck upper with contrasting pops of Blue in lieu of the older shoe’s Tour Yellow accents. They appear on the sneaker’s molded eyelets, interior tongue, quarter panel, throat and midsole, which packs visible Air-sole cushioning under the heel. Jumpman branding decorates the tongue tag and heel.
