As with all of our other Salt-Water Sandal styles the Retro Slide is made from our signature 100% waterproof leather and can be hand washed using warm water and a gentle detergent. Originally sold in the USA in the 1970s, we have updated the classic Retro from the archive collection into a modern and practical slider sandal. The Retro Slide in tan is a great every day slider and works with all outfits - from boho chic to everyday officewear.
