Using these Spring Step L'Artiste Delila sandals is a breeze. Just adjust the hook - and - loop straps to your preferred tightness for a perfect fit. Slip your feet in and you're ready to go. When it comes to sizing, they fit true to size, so you don't have to worry about getting the wrong size. For maintenance, avoid getting them wet as much as possible. If they do get dirty, use a soft, dry cloth to gently wipe the surface. Don't use harsh chemicals or abrasive materials as they can damage the leather and the hand - painted details. Store them in a cool, dry place when not in use. Keep in mind that due to the natural tanned leather and hand - painting techniques, there will be some color variations, which is part of their unique charm.
