Dr Martens Polley Mary Jane takes the grade school uniform look and turns up the edgy schoolgirl rebellion. The Polley T-Bar has the Dr. Martens iconic AirWair™ air-cushioned bouncing sole, that’s oil and fat resistant with good abrasion and slip resistance. The boot is Goodyear welted, meaning the upper and sole are sewn together in our heat-sealed z-welt stitch for enhanced comfort.
