These men's rubber thongs are super easy to use. Just slip them on your feet and you're ready to go for a casual walk, a trip to the beach, or any daily activity. When using them, make sure to walk on dry or slightly wet surfaces as the non - slip sole works best then. Avoid wearing them on extremely rough or sharp surfaces to prevent damage to the rubber. For maintenance, simply rinse them with water after use at the beach or in dirty places. You can use a mild soap if they're really dirty. Let them dry naturally in a well - ventilated area. That way, your thongs will last a long time.
