These sandals are easy to wear. Just slip them on like you would with any regular sandals. For best results, make sure your feet are clean and dry before putting them on. When it comes to the LED lights, they are built - in and ready to shine as soon as you turn them on. Be careful not to step on sharp objects as it might damage the clear vinyl part. To maintain these sandals, use a soft cloth to wipe them clean after each use. Store them in a cool, dry place away from direct sunlight to keep the vinyl looking clear and the LED lights in good condition.
