About the Nigel Sylvester x Air Jordan 4 Retro OG SP 'Brick After Brick'

The Nigel Sylvester x Air Jordan 4 Retro OG 'Sail' showcases the classic color blocking featured on the original 'Fire Red' AJ4. Off-white leather is utilized on the upper, complemented by breathable quarter panel netting and black TPU support wings. Cinnabar red accents highlight the molded eyelets, collar lining, and the mini-Swoosh embroidered on the lateral forefoot. Classic Jumpman branding appears on the woven tongue tag, while 'BIKE AIR' replaces the usual Nike Air logo on the heel tab.
