Genuine leather upper and lining Three interlocking straps across the front Slender ankle strap with buckle fastening Size info & Care To find the right size, please refer to the size chart in the images above. Please read how each model fits in the descriptions below. These are general guidelines and of course your exact size and fitting will ultimately depend on your personal preference and the overall structure of your foot. Because these are open toed shoes people like to wear them differently (toes close to edge / not close too the edge!) Kids shoes should NOT be purposefully bought larger in order to make the sandal "last longer" as the traditional fit of this brand is pretty roomy. With any of the sandals, should you get a sore spot, dunk your foot & sandal into water (yes really!) and wear them until they dry. Remember, every model can be used as a swimming shoe and can be put through the washing machine on gentle cold wash. Fits comfortably wide. Before you put them on for the first time, stretch out the toe straps and gently bend the sole to ease. Best fitted with toes behind the stitch line. DO NOT oversize for children with the hope they will last longer.
