People wear compression socks mainly to improve circulation in their legs by applying graduated pressure, which helps blood flow more effectively back to the heart. This prevents blood pooling, decreases swelling, reduces pain and discomfort, and lowers the risk of blood clots such as deep vein thrombosis (DVT). They are beneficial for people who are on their feet for long periods, those who sit for long durations (like travelers), individuals with medical conditions such as varicose veins, diabetes, or lymphedema, and athletes to enhance exercise recovery and reduce muscle soreness. Additionally, compression socks can help prevent dizziness upon standing and improve lymphatic drainage. They are also used post-surgery and during pregnancy to manage leg swelling.
