The SWIMS Penny Loafer reinvents a timeless favorite—the 19th-century Norwegian Aurland Penny Loafer—with contemporary style and reliable functionality. A non-marking rubber outsole and comfortable EVA insole make the "good life" much easier, and the iconic SWIMS ventilation and drainage technology make this your favorite pair of shoes. This style is machine-washable and antimicrobial for safety and long time use. SWIMS loafers are made from natural rubber and TPU, requiring the same care as leather. Gently use a sponge and silicone spray to clean, shine and remove scratches. Our loafers are water-friendly, so can be machine washed. To wash, remove the insole and place both in a washing bag. Use normal detergent without fabric softener. Air dry. Do not tumble dry.
