To use these NAOT Dorith sandals, simply adjust the hook and loop strap to fit your foot comfortably. Slip your foot in and make sure the backstrap provides the right support. When it comes to sizing, remember that they run true to size, but if you're a half - size, go up a size for the best fit. For maintenance, keep them away from excessive moisture. You can clean the leather with a soft, dry cloth. If there are stains, use a mild leather cleaner. Avoid wearing them in very wet conditions as the suede footbed might get damaged. And since they're not slip - resistant, be careful when walking on slippery surfaces.
