Blue Flame Footwear® thermal socks are made from thick, heavy duty acrylic fibers that have undergone an intensive brushing process, designed not only for warmth but to provide maximum comfort. The brushed acrylic inner provides ultra-soft cushioning while trapping air, preventing the escape of your coveted body heat even at insanely low temperatures. This one-of-a-kind manufacturing process is what makes Blue Flame Footwear thermal socks truly the worlds warmest socks.
