Soyance compression socks are a medical device indicated for the treatment of venous insufficiency by exerting a decreasing pressure from the ankle to the calf. By facilitating venous return, the use of this type of compression socks effectively relieves pain and heaviness in the legs, and limits the risk of varicose veins and venous thrombosis. They can be used preventively or curatively. Worn all day or on a long plane trip, for example, they provide comfort from the very first moment. They are thermoregulatory, very soft, flexible and comfortable, ideal in thin boots or moccasins. These Class 2 compression socks have pressure characteristics of 15-20 mmHg.
