This design also comes in a lower compression level of 15-20 mmHg. Our stylish compression socks help energize legs, reduce swelling, alleviate achiness and heaviness, and aid in muscle recovery. Perfect for travel, nurses, runners, pregnant women, teachers, hair stylists, retail workers or those who sit or stand for long periods.
