How do compression socks work? The pressure is tighter around the ankles and looser going up the legs to stimulate blood circulation. The veins are stimulated to pump deoxygenated blood back to the heart and lymph nodes, which speeds up muscle recovery. What size do I need? Use our size chart to determine your size. It can be found by looking at the product photos. Sizes are based on two measurements: your shoe size and your calf circumference, measured around the widest part of your calf.
