THERAFIRMlight™ Women's Trouser Socks are designed to help energize tired legs and feet, improve circulation, and assist in the prevention of swelling and varicose veins. Medically correct gradient compression delivers a controlled amount of pressure greatest at the ankle and gradually decreases towards the top of the stocking to promote better blood flow. These support socks feature diamond patterns in fashionable colors, a non-binding, knit-in band that holds the socks in place all day, and comfort heel and toe. Micro-Cool® process creates a wicking effect so moisture evaporates from the skin quickly, therefore providing a comfortable coolness. Lycra® and nylon blend.
