Using these sandals is a breeze. First, charge them via USB. Once charged, turn on the LED lights and choose your favorite color or lighting pattern. When putting them on, make sure the ankle strap is snug but not too tight. Always use the charger provided to avoid damaging the battery. Keep them away from water to prevent damage to the lights. After use, store them in a cool, dry place. Wipe them clean with a soft cloth if they get dirty.
