To use these sandals, simply adjust the ladder lock buckle to get your desired fit. You can do this easily even when you're on the move. When wearing them, keep in mind that they are suitable for all-day wear, but if you plan to do a lot of heavy - duty activities, give your feet a break occasionally. For maintenance, clean the sandals with a mild soap and water after use. Avoid using harsh chemicals as they may damage the materials. Let them air - dry away from direct sunlight to preserve the color and integrity of the webbing and rubber.
