The Sun-SanĀ® Swimmer has a slightly narrower fit and, like all Sun-SanĀ® Sandals, the Swimmer comes on a lightweight, cushioned urethane sole. Rust-proof brass buckles and scuff-resistant, water friendly genuine leather make them ideal for in-and-out of water wear. They clean up so easily, and with proper care will last for years. These are great summer sandals.
