Heat Holders®: Makers of The Warmest Thermal Sock
Believing that feet should never be cold, Heat Holders® invented The Warmest Thermal Sock in 2008 using a proprietary three-stage manufacturing method.
Our innovation didn’t stop there. Inspired by our customer feedback, we continue to expand our product line of thermal socks, accessories, base layers, loungewear and active wear that keep you covered in warmth, softness, and comfort from head to toe despite the cold conditions.
