Introducing the Tan Retro. Reminiscent of the Mexican Huarache sandal originally popular in the 1960s, The Retro sandal is another model that Salt-Water Sandals have relaunched over forty years later in an array of gorgeous colours. From our signature core colours to metallics and brights - The Retro in Tan is the ultimate everyday summer sandal. Defined by our 100% waterproof leather, rust proof buckles these can be hand washed using warm water and a gentle detergent.
