Welcome to an entirely new way to get formal: the Winchester 7-eye zip boot. Elegant, slender lines and subtle stitching details are a rich, luxurious nod to heritage British boot designâwhile the iconic Doc DNA lives on in the Winchester's subtly scripted heel loop, branded zip pulls and comfortable air-cushioned sole. Beau Brummel would be proud. The Winchester 7-eye zip men's boot is constructed on the iconic AirWair bouncing sole, that's oil-and-fat resistant with good abrasion and slip resistanceâand has been since 1960. This shoe is Goodyear-welted, meaning the upper and sole are sewn together in a heat-sealed z-welt stitch for enhanced comfort. The Winchester is made with Polished Smooth, a durable, polished take on the classic Dr. Martens leather. Material: Leather.
