Using these sandals is a breeze. Just slip them on with the hook - and - loop closure and start enjoying the gentle massage for your feet. When wearing, make sure your feet are clean and dry to maximize comfort. Avoid wearing them in extremely wet or muddy conditions to prevent damage to the leather and sole. To maintain these sandals, use a soft cloth to wipe off any dirt regularly. For the leather parts, you can apply a small amount of leather conditioner occasionally to keep it soft and supple. Store them in a cool, dry place when not in use to preserve their quality.
