The SWIMS Penny Loafer reinvents a timeless favorite- the 19th-century Norwegian Penny Loafer- with contemporary style and reliable functionality. A non-marking rubber outsole and and durable last and vamp edge make the good life much easier, and the iconic SWIMS ventilation and drainage technology make this your favorite pair of shoes. We've added a Bloom algae foam insole and cooling top cloth, a sustainable alternative to traditional insoles that help clean our air and water, so you can look good while doing good.
