The Nigel Sylvester x AJ4 RM SP Grandma's Driveway 'Grey' marks the BMX superstar’s innovative collaboration with J Brand on a new version of the AJ4, remastering the iconic silhouette with lower profile construction. Unique touches include 'Bike Aiir' logos on the heel and tongue, which have quickly become an iconic feature of the model. Unofficially dubbed the AJ4 Low, this refreshed model features a dark grey suede upper with a supportive TPU cage and a red mini-check on the lateral forefoot. The sneaker sits on a two-tone midsole, combining black and off-white with visible sole cushioning.
