Compression Hosierys are specially made, snug-fitting, stretchy socks that gently squeeze your leg. The pressure these stockings put on your legs helps your blood vessels work better. The arteries that take oxygen-rich blood to your muscles can relax, so blood flows freely. The veins get a boost pushing blood back to your heart. Compression Hosiery’s can keep your legs from getting tired and achy. They can also ease swelling in your feet and ankles as well as help prevent and treat spider and varicose veins.
