Not all compression socks are created equal. Our compression garments, unlike most on the market, have FDA approved true graduated compression that is tested to be tightest at the ankle and gradually looser as you move up the leg. Be sure yours are made in the USA with medical grade FDA approved testing to ensure the compression is properly graduated and is in the indicated range (i.e. 20-30 mmHg).
