These gel socks provide moisturizing care for your feet just by wearing them. The moisturizing gel, containing jojoba oil and olive oil, envelops your heels, keeping them moisturized throughout wear. The socks can be washed and reused. How to use: Wear them on clean heels. If your heels are particularly dry, it's recommended to apply moisturizer before wearing. You can also wear them overnight for moisturizing care until morning. Brand new, unused. Please understand that these have been stored at home. Those who are very particular about condition, please refrain from purchasing. Feel free to comment if you have any questions or would like additional photos. I have many other items for sale, so please take a look if you'd like. ^ ^
