THERAFIRMlight™ Pantyhose 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 fashionable, sheer support pantyhose are made with breathable fibers to provide shaping support and feature a soft knit-in waistband to prevent rolling and enhance comfort. Micro-Cool® process creates a wicking effect so moisture evaporates from the skin quickly, therefore providing a comfortable coolness. Lycra® and nylon blend. 10-15 mmHg compression.
