Heat Holders® Women’s Thermal Socks keep feet warm and comfortable whether you are heading to the office, walking the dog, or relaxing at home. Advanced thermal yarn and our deeply brushed interior help trap warm air next to the skin, keeping your feet warmer for longer without adding bulk. Choose from 3 Levels of Warmth: 7X, 5X, or 3X warmer than the average cotton sock to suit how cold you feel and the shoes you’re planning to wear, including options for formal shoes, work boots, lounging at home, and outdoor adventures. Many designs help manage moisture and resist odor, and everything is machine washable for easy care. Build your ideal cold-weather outfit by pairing women’s thermal socks with matching women’s thermal hats, and women’s thermal gloves.
