These Mens Lite Marsoll Socks in Navy & Merlot boast an impressive 1.6 TOG rating, making them four times warmer than a basic cotton sock. They give you the ideal balance between thickness and warmth, allowing you to enjoy long-lasting comfort in your casual shoes all winter long.

Soon after we launched our famous Original socks, we set out to create the warmest thermal sock for more casual-fitting footwear. Following twelve months of testing, development and research, the Heat Holders Lite thermal socks were born.

Heat Holders men's thermal socks are sure to keep your feet warm on even the coldest days. We believe that whatever you’re doing, inside or out, you should feel comfortable and content so you can enjoy life to the full.
