What It Means When Socks Leave Marks on Your Legs — and When to Worry

Sock marks can look more alarming than they are. Many people notice thin lines around the ankles or lower legs after a long day, especially when socks fit snugly or the body has been still for hours.

A HuffPost article, republished by BuzzFeed on May 3, 2026, spoke with vascular surgeon Dr. Katherine Teter of Hackensack University Medical Center in New Jersey and family physician Dr. Brintha Vasagar in Wisconsin. Their message was clear: sock lines are usually normal, but certain patterns deserve medical attention.
