WEAVING STYLE & QUALITY INTO THERAPEUTIC THREADS. Made with premium cotton and a 200-needle count for flexibility and comfort. Our socks offer moderate-firm compression (20-30 mmHg). 20-30 mmHg is considered medical-grade compression and is generally recommended or prescribed by your doctor. This design also has a lower compression level of 15-20 mmHg. Our stylish compression socks help energize legs, reduce swelling, alleviate achiness and heaviness, and aid muscle recovery. Perfect for travel, nurses, runners, pregnant women, teachers, hair stylists, retail workers, or those who sit or stand for long periods.
