Blue Flame Footwear by EcoSox

Blue Flame Footwear thermal socks are manufactured 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. So why the name Blue Flame Footwear? The warmest part of a flame is the part closest to the energy source, and when hot enough, actually gives off blue light. Because we have developed a sock seven times warmer than a cotton sock, we couldn't find a more fitting name.

So What Makes Blue Flame Footwear Originals so Warm?

It's a combination of thick looped acrylic and an intensive brushing process that gives our thermals their remarkable heat retention. In developing what we wanted to be the warmest sock in the world, we knew it would be imperative to create a thick looped fiber sock for the insulation necessary to provide superior body heat retention. As we continued our research in different technologies available in hosiery, we discovered a process of brushing the inner loops of acrylic fibers that helps to trap heat within long looped fibers by keeping microscopic air pockets close to your feet. This trapped air is what holds your body heat in and blocks out frigid below freezing temperatures. So with the combination of a thick and heavy duty fiber and a comprehensive inner brushing process, Blue Flame Footwear thermal socks were born.   Blue Flame Thermal Socks
