Dr. Martens Penton Two-Tone Leather Loafers. Keep it classic. The Penton loafer is a tassel-free, wider-fitting alternative to our Adrian loafer. It features subtle detailing across the upper, including a saddle strap and moc-toe stitching. The loafer is made from black Smooth leather with contrasting white Smooth leather across the vamp and around the top of the ankle. Dr. Martens' bouncing sole retains its signature grooved edge but is reworked in black with matching welt stitching. Imported.
