Special foot care while you sleep. Just by wearing them, you can take care of dry heels, and the incorporated materials and special moisturizing sheets keep your feet moisturized. Easy and recommended because you can easily care for your feet just by wearing them while you sleep or during relaxation time! I received these a while ago, but I'm selling them because I don't use them. They have been stored at home for a long time. They are new and unused, but the outer bag shows some signs of wear. Please refrain from purchasing if you are looking for a perfect product or if you are sensitive to such things.
