Kids can look stylish in Dr. Martens' classic Mary Jane. An adjustable T-bar buckle fastening ensures the perfect fit, and a grooved edge, visible stitching, and iconic air-cushioned sole offers resistance against oil, fat, abrasions, and slips. The leather upper is signature Airwair, firm and semi-bright. To keep the shoe fresh, clean with a damp cloth and polish with colored wax. Be sure to follow the size guidelines listed for US and UK, allowing for some wiggle room.
