The Sun San See Wee is your child's introduction to this fabulous brand. This sandal has a light weight and flexible sole. The adjustable strap at the front means they are a great fit on younger feet. Like Salt Water Sandals they are sun, sand and sea resistant. We have listed the length of each of the sizes below, but if you are at all concerned please email us at info@cocoonliving.com and we can send you a chart to place your child's foot on.
