Salt-Water Original Sandal comes with rust-proof buckles, can be worn in the water and can be hand washed with a gentle detergent. These are the perfect strappy sandals for summer adventures as beautiful as they are comfortable. *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.
