Based on the original Salt-Water design featuring a plaited leather upper and adjustable strap across the ankle. The differences are the Swimmer has a slightly narrower fitting and, like all Sun-San Sandals, it comes on a spongy urethane sole with rust proof buckles. All children sizes are made with a velcro fastening under a faux buckle across the ankle strap for day to day ease. The Swimmer is a water shoe and can be hand washed with a gentle detergent. The tan Swimmer sandal is a classic summer shoe, great for little boys and girls.
