What does "20–30 mmHg" mean?
Compression is measured in mmHg (millimeters of mercury) — how much pressure the sock applies to your leg, strongest at the ankle and easing up the calf (graduated compression). 20–30 mmHg is moderate compression — more pressure than everyday socks, for noticeable swelling and circulation concerns while still wearable all day.

Surgeon-designed for real leg health
Dr. Johnny's compression wasn't designed by a marketing team. It was developed by Dr. Jean Segal — a surgeon with over 35 years treating patients with venous disease, swelling, and circulation problems. Every level we offer exists because his patients needed it: stylish enough to wear every day, effective enough to make a real difference.
