Limited to friends and family, the Nike SB x Air Jordan 4 Retro SP 'Varsity Red' dons an off-white leather upper tooled with the classic netting, plastic support wings, and a grey suede forefoot overlay. A red Jumpman tongue tag matches the molded eyelets and the Nike SB-branded heel tab. The midsole showcases a visible Nike Air heel unit while the outsole uses sturdy gum rubber.
