What is the primary purpose of anti-embolic stockings?

The primary purpose of anti-embolic stockings is to prevent blood clots. These specially designed stockings apply graduated compression to the legs, which promotes venous return and helps reduce the likelihood of stagnation of blood in the lower extremities. By providing this consistent pressure, the stockings encourage blood flow back to the heart, which is crucial in preventing conditions such as deep vein thrombosis (DVT).

While keeping feet warm, increasing blood flow, and supporting ankle mobility may be secondary benefits, their main function is centered around the prevention of blood clots, which is particularly important for individuals who are immobile or undergoing surgery, as their risk for developing clot-related complications increases significantly in these situations.
