This Salt-Water Original Sun-San Surfer is a classic double buckle sandal and is defined by its 100% leather upper, soft sole and rust-proof buckles. This sandal is a water shoe that can be hand washed using a gentle detergent. The perfect summer shoe for both boys and girls. *IMPORTANT* Salt Water Sandals are manufactured in US sizes. The size on the sandal and on the box is the US size. US sizes are one size bigger than UK sizes. For example a UK size 9 is equivalent to a US size 10.
