Light Support Designed to help energize tired legs and feet, improve circulation, and assist in the prevention of swelling or other conditions as recommended by your physician.. “Tired & achy legs” often is the complaint we hear from customers. Compression socks are designed to put pressure on the lower part of the legs to facilitate circulating blood up to the heart. Sitting or standing, whether on the job or flying for a long period of time will cause achy and tired legs. THERAFIRM® created the most comfortable compression socks using the patented Micro-Cool® process which creates a wicking effect, so moisture evaporates from the skin quickly for healthy feet. Antimicrobial silver fibers wick moisture away from the skin and help prevent odor in the sock. CONTRAINDICATIONS: Compression products should not be worn and is contraindicated if you have any of the following conditions: Severe arterial insufficiency, cutaneous infections, acute dermatitis, wet dermatosis, uncontrolled congestive heart failure, skin irritations, allergies to dyes. NOT TO BE WORN WHILE SLEEPING.
