The knit construction makes the fabric very stretchable and forgiving, which makes this sock easy to don and easy to wear. A silicone beaded grip-top keeps these thigh highs firmly in place. Double-covered spandex yarns add to their comfort and durability. This is an excellent choice for people with poor hand strength, arthritis, or limited range of motion. Made from 69% nylon and 31% spandex in USA.
