Step into a classic. This AJ4 throws it back with full-grain and synthetic leathers and premium textiles. Lush colors update the icon, while original design elements—like floating eyestays and mesh-inspired accents—feel just as fresh as they did in '89. Full-grain and synthetic leathers in the upper make for a durable shoe. Free-floating eyestays at the ankle pull down over your foot when you lace up. Nike Air technology absorbs impact for cushioning with every step. Rubber in the outsole gives you everyday traction.
