How much do you move during the day? If you spend a lot of time sitting, your calf muscles that usually help pump blood through your veins do very little. This can cause swelling and blood to pool in the lower legs. Standing all day can have the same effect. Walking is a great exercise to help the calf muscles do their job. Socks with compression squeeze your legs to move blood up your leg whether you are sitting or standing. Voxx Knee Highs offer gentle compression, are comfortable to wear and have HPT to help with pain, balance and stability.
