Compression socks can help lower the risk of developing blood clots, like deep vein thrombosis (DVT), during long periods of sitting, such as on flights or car trips. By applying gentle pressure to your legs, they encourage healthy blood flow and help prevent blood from pooling in the lower legs.

They’re especially helpful for people with circulation issues or a history of clotting concerns. If you’re unsure whether you need them for travel, it’s worth asking your doctor.
