They improve blood and lymphatic circulation by applying pressure to the legs.

Compression therapy works by squeezing the veins in your legs and feet, making them narrower, which helps blood flow up the legs toward the heart. Better circulation keeps fresh, oxygenated blood flowing to energize muscles, reduce soreness, and prevent clots and circulatory conditions.

Graduated compression therapy is the most effective form of compression, and works differently than regular compression socks. With graduated compression, pressure gradually decreases from the ankle toward the knee, which helps blood flow effectively return to the heart instead of pooling in the feet

Socks are the most effective and convenient way to get the benefits of compression therapy by changing out one item you already wear every day.
