RelaxSan unisex cotton support socks exert high graduated compression (pressure of 22-27 mmHg at the ankle). They are indicated for the treatment for varicose veins, phlebitis, oedema and venous insufficiency, as well as the prevention of thrombosis after surgery. These support knee-length socks are also referred to as travel socks because they are suitable for people who make long journeys or carry out a job that is mostly static. Thanks to their high-quality cotton fabric, they are thin, hypoallergenic and breathable, while the soft elastic band under the knee and the seamless toes provide you with maximum comfort. In order to choose the right compression level, please pay attention to the size chart and select the right size. Fabric content: 53% cotton, 31% nylon, 16% elastane.
