Whether you spend long days sitting at a desk, are taking a lengthy flight or, conversely, are on your feet for hours at a time, compression socks may help improve circulation and ease swelling, pain and that heavy feeling in your legs.We spoke with experts to find out how compression socks work and which brands are worth trying. Sigvaris, Sockwell and Nurse Yard topped their lists for comfort, style and compression strength.Inactivity, sitting or standing all day can cause blood pooling, which leads to swelling and an uncomfortable, heavy feeling in the legs, explains Dr. Anne Sharkey, a board-certified podiatrist based in Austin, Texas. Compression socks work "by applying external pressure to the lower legs," which helps move blood back to the heart and reduces blood pooling in the legs, feet and ankles, easing aches and fatigue."Normally, the muscles in the legs pump and bring back the blood to the heart," Dr. Samantha Landau, professor at Touro New York College of Podiatric Medicine, tells us. With age, genetics, too much pressure on the legs or lack of activity, the valves can weaken. According to Dr. Landau, compression socks help relieve pain and can lower the risk of blood clots.Most experts noted that the level of compression matters over brand popularity. 15–20 mmHg compression socks offer moderate pressure, making them good for daily use. 20–30 mmHg compression socks give stronger, firmer, more restrictive pressure that experts say may be best for pain management.Compression socks can benefit people who spend long stretches sitting or standing, including passengers on long flights, flight attendants, nurses and office workers, by helping improve circulation and reduce swelling and pain.They’re also commonly worn during pregnancy and postpartum to help with swelling. Athletes often use compression socks during or after workouts to support recovery and relieve muscle strain.The experts also say that patients with chronic leg pain, those who are bedridden and wheelchair users may also benefit from compression socks, depending on their health needs.READ MORE: Expert-recommended shoes to help with plantar fasciitis, starting at $75The best and most comfortable options for travel, nurses, pregnancy, pain and sports — backed by experts.Sigvaris' sheer compression socks are particularly recommended for patients with medical conditions.
