Compression tights for the appearance of varicose veins due to pregnancy (or other situations) in smoke grey and in transparent form. Pressure is applied on certain parts of the leg to try to prevent varicose veins and venous insufficiency. The pressure is applied from the bottom upwards, reaching the thigh. Thus, it favors the circulation of the blood that goes to the heart. In addition, some veins are compressed, so that they no longer dilate and no longer store blood inside. It can be used in any circumstance: for days when the legs are swollen, before or after the appearance of varicose veins and to regulate blood circulation. Veinax tights, which are indicated for women, can be used to apply pressure to the legs.
