The Swimmer design is based on the original Salt-Water featuring a plaited leather upper with buckle ankle strap. The differences are the Swimmer has a slightly narrower fitting and, like all Sun-San Sandals, the Swimmer comes on a spongy urethane sole with rust proof buckles. They can also be worn in the water and put through a cool machine wash. The white Swimmer is a great summer holiday sandal. Comfortable, durable and stylish.
