The Shark is a traditional fisherman style sandal with a semi-closed toe offering extra protection. Like all Sun-San Sandals the Shark comes on a spongy urethane sole with rust proof buckles. They can also be worn in water and hand washed using gentle detergent. This style works best on a slimmer foot. The US sizing is a size shorter than the UK equivalent so we recommend sizing up. The leather upper has a slight stretch so should feel reasonably snug at first.
