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 are relaunching over 40 years later in an array of gorgeous colours. From our signature core colours to metallics to brights - The Retro in tan is the ultimate everyday summer sandal. The Retro woven sandal is defined by its 100% waterproof leather, rust proof buckles and can be hand washed using warm water and a gentle detergent.
