The Nigel Sylvester x Air Jordan 4 Retro OG SP 'Brick By Brick' delivers a monochrome suede upper finished in Firewood Orange and features heritage details, including quarter panel netting, molded eyelets and TPU support wings. The tonal design is disrupted by discreet off-white accents, including the Flight logo on the woven Jumpman tongue tag and an embroidered mini-Swoosh on the lateral forefoot. Bike Air branding adorns the heel tab. A Sail-colored polyurethane midsole packs visible Air-sole cushioning in the heel for a comfortable ride.
