Using these Foo Sah sandals is super easy. Just slide your feet into the padded insole and zip up the back zipper. You're then ready to show off your style. When it comes to sizing, remember they run a bit big, so it's better to size down. As for maintenance, use a soft cloth to gently clean the surface. Avoid getting them in too much water, especially if you want to keep the beads and chains looking nice. Store them in a cool, dry place when not in use to keep them in good condition.
