The vented heel gel socks are made of quality fabric along with a Smart gel technology that is concentrated in the heel area. This material is also stretchable and can take shape and provide comfort and relieve to anyone irrespective of the feet size. With its ergonomic design, the heel gel socks provide complete support to the feet, heels, balls of the feet and ankles. This helps in preventing sprains and also helping in moisturizing cracked heels. The heel gel socks are designed to give you an all day comfort as the soft gel with the breathable fabric allows moisture and air to reach the skin. Cracked heel treatment socks can be comfortable for sensitive skin! Our open toe socks are made of silicone, making them safe and comfortable for sensitive skin, unlike many other gel lined socks. Treating a crack or callus on your sensitive skin no longer means putting up with irritating moisturizing sock sets.
