Urban compression socks. They reduce venous dilatation by preventing blood from pooling in the lower limbs, thus promoting venous return. In fact, this is due to the pressure they exert from the ankle to the calf. Thus, dilated veins are tightened, venous return is ensured, pain and heaviness in the legs are reduced and the appearance of oedema is reduced. These compression socks are worn during the day to tone blood circulation and promote venous return. They have a class 2 compression that compresses the vessels through the skin and thins the blood. The main challenge is to reduce stasis and thus prevent the accumulation of toxins resulting from metabolism around the cells.
