Ahead of its time in '99, the innovative Air Max SNDR is back and louder than ever. From the secure fit around the heel to the zip-up shroud, this legendary sneaker continues to break the mould. Unzip the shroud to reveal "6453", a nod to the last 4 numbers of Nike's office numbers around the world, which spell out N-I-K-E on the keypad. Benefits: Neoprene-like upper feels smooth and stretchy. Zip-up shroud covers your laces for a sleek look. Reflective-design vented panels create a breathable feel. Max Air cushioning in the heel and forefoot adds exceptional bounce and comfort. Product details: Pull tabs. Foam midsole. Rubber outsole. Not intended for use as personal protective equipment (PPE) Max Air unit: Visual stunner. Window to the sole. Legendary designer Tinker Hatfield took cues from inside-out Parisian architecture to re-establish Air technology as a leader in cushioning. Plush and comfortable, the Max Air unit has just the right amount of support.
