How to use: Just put on the sandals like you would any other pair. The hook and loop strap makes it easy to adjust for a perfect fit. Notice that if you're a half - size, size up for the best comfort. Maintenance: Keep them clean by using a soft brush or cloth to remove dirt. Avoid getting them too wet, as this can damage the cork footbed. If they do get wet, let them dry naturally away from direct heat. Also, you can remove the footbed and clean it separately for better hygiene. With proper care, these sandals will last you a long time and keep your feet happy.
