ACG Air Wildwood sneakers The Nike ACG Air Wildwood is back 30 years after its 1989 debut. These sneakers are constructed entirely from leather - in brown, cream, black and blue - and feature a perforated base layer and panelling along the mudguard, heel, and Swoosh. Underneath, the waffle sole adds traction, while ACG branding on the midsole and tongue round out the look. Imported Composition Sole: Rubber 100% Outer: Leather 100% Lining: Fabric 100%
