Compression socks, also known as compression stockings, are specialty socks that gently push on your ankles and legs. Compression stockings are used for comfort, to perform better in sports, and to fend off major medical issues. They essentially increase your blood flow. They can reduce leg pain and swelling. You or your doctor will need to choose which one will work best because they come in various sizes and intensities. They are available over the counter or online, but if your doctor prescribes them, your insurance may cover the cost. Depending on the type you purchase, the price each pair might range from about $10 to as much as $100.
