These women's thermal crew socks are specifically designed for colder months, featuring a high bulk acrylic yarn and a reinforced heel and toe for extra durability. With a soft, brushed inside and an antibacterial treatment, these socks keep feet fresh and odor-free. Plus, the heated moisture control keeps feet dry with a TOG rating of 2.13. Available in a random mix of colors, including pink, green, blue, hot pink, dark pink, and teal. Made with a blend of acrylic, nylon, and polyester, these socks should be washed separately in dark colors and dried on low heat inside out.
