Compressa Compression Socks Though they are often worn upon a doctor’s advice, compression socks are available to anyone. Many people choose compression socks because they provide comfort during pregnancy, long days on your feet, a punishing workout, or travel. There is no downside to wearing them as long as you are comfortable.Compression socks work by squeezing the walls of the veins and leg tissues to help blood work its way against gravity to the heart. In other words, they improve circulation. There are also gains in the flow of the lymph fluids that bathe your legs’ cells. These improvements lead to less leg fatigue, achiness, and swelling.
