20-30 mmHg Compression Socks

20–30 mmHg compression is a firm, medical-grade level designed to provide targeted, therapeutic pressure for everyday support and medical use.

“mmHg” stands for millimeters of mercury, the unit used to measure pressure. 20–30 mmHg indicates firm, medical-grade compression, meaning these socks apply 20 to 30 mmHg of graduated pressure from ankle to calf to help improve circulation and reduce swelling.

This level of compression is ideal for people who need extra leg support — including those who stand or sit all day, frequent travelers, athletes, or individuals managing moderate swelling, varicose veins, or circulation concerns. Many people also wear 20–30 mmHg socks during pregnancy or post-surgery (with their doctor’s guidance).

No prescription is needed! VIM & VIGR’s 20–30 mmHg socks offer the same medical-grade compression used in clinical settings, but they’re available over the counter, and designed to look and feel great for everyday wear.

Absolutely. 20–30 mmHg compression is widely recommended for long flights, intense workouts, recovery days, and managing swelling after medical procedures. If you have a specific medical condition, check with your healthcare provider before wearing higher compression levels.
