Anti-embolism Stockings Knee-High are knee high compression socks that are the most ideal for patients that are bedridden or non-ambulatory. These pressure stockings are effective at reducing pulmonary embolism, especially for patients that cannot move around and circulate blood normally. These knee high compression socks come in a natural-looking beige color, and are equipped with a graduated compression that allows for a gentle graduation of blood flow from the ankles to the knees.
