The fabric is also moisture-wicking and odor fighting, preventing a case of smelly feet during exercise and long flights. ✅IMPROVED CIRCULATION: Compression stockings use a specialized weave of strong elastic to create pressure on the muscles in the legs, ankles, and feet.

This helps your legs feel lighter and reduces pain and discomfort related to underlying vein disease. ✅FIND YOUR STYLE: Our graduated 20-30mmHg compression socks come in more than 30 color/design choices that include hearts, polka dots, argyle, skull, and stripes, it is sure to match every outfit you have in your closet.
