Gel Therapy Socks help prevent dry cracked skin without the use of messy creams and lotions for people with diabetes or other dry skin conditions. The socks are lined with Silipos' proprietary soft polymer fragrance-free gel that comfortably conforms to your feet while gradually releasing medical grade mineral oil to moisturize and lubricate the skin.The gel is hypoallergenic, does not support bacterial growth and has been dermatologist tested. The cotton/nylon/Lycra socks are latex free and have a non-restrictive cuff that keeps them s from falling down but does not restrict circulation. Can also be worn as warming socks if you have arthritis. Gel Therapy Socks are washable and reusable and, when worn for two to three times per week, will provide moisturizing benefits for up to three months, depending on frequency and length of use.
