The Nigel Sylvester x Air Jordan 4 Retro OG SP 'Brick By Brick' sports a monochromatic, orange suede upper with the traditional quarter netting, molded eyelets and plastic support wings. Off-white accents land on the Flight logo, Jumpman tongue tag and an embroidered forefoot mini-Swoosh. The Bike Air insignia adorns the heel tab, while an off-white foam midsole packs an Air-sole heel unit for soft cushioning.
