Unlike other Anti-Embolism Stockings, Bell-Horn offers a true graduated compression, which means you can wear these in and out of the hospital. Provides a gentle massaging action to help prevent the formation of blood clots associated with post-surgical inactivity. Helps relieve mild swelling. All of our Anti-Embolism stockings are latex-free. Black and beige colors have been a popular choice for the ambulatory patient who doesn’t want to sacrifice fashion.
