Using these Chaco women's sandals is easy. Just put your foot in and adjust the double - strapped upper and heel risers using the ladder lock buckle to get a perfect fit. The toe - loop should be snug around your toes for better control. When you're out and about, these sandals will keep your feet comfortable and supported. For maintenance, clean them with a mild soap and water after use, especially if you've been in dirty or wet conditions. Avoid using harsh chemicals as they may damage the webbing or the outsole. Store them in a cool, dry place when not in use to keep them in good condition. Also, if you notice any signs of wear and tear on the straps or the sole, it might be time to consider replacing the sandals.
