What Size Do You Need?

Blue Flame E-Tech thermals not only insulate but use the super moisture-wicking properties of bamboo viscose to keep feet drier. While moisture build-up typically defeats most socks' insulative properties, these E-Tech are designed with thick inner loops of cushioning that trap heat and keep your feet warm and dry for hours.  You can feel this sock working when you remove your foot from your footwear and you feel a wave of cool air created from rapid evaporation of moisture.  This sock rates four flames out of four for thermal properties.

  • Bamboo viscose looped thermal pile trap and hold heat.
  • The knitted smooth integrated toe seam stitching reduces friction.
  • Natural moisture-wicking materials help keep feet dry and blister-free.
  • Arch support for comfort to fight foot fatigue.

Why Bamboo Socks?

Bamboo is an ecologically friendly plant to farm. Unlike other materials, bamboo viscose performance attributes are natural, so there is no need for chemical additives or fabric conditioners. Bamboo viscose has a silk-like feel and is ultra-soft against your skin, which reduces friction and makes for really comfortable socks. Learn more...

    I was looking for a good pair of moisture wicking socks and heard about bamboo socks. I also heard really good things about eco socks and while these are the most comfortable socks I’ve owned they do not wick the moisture away and after the first wash, so the second time wearing them they have already started to rip. Honestly a little disappointed

    Bamboo sox

    Posted by Russ Anderson on Apr 4th 2018

    I always wear 2 pairs of sox , thin EcoSox and thick ether wool or Blue Flame sox.
    I always wear heavy hiking shoes.
    I never wear cotton sox. cotton causes blisters and they do not get rid of the sweat.
    I am 85 years old and have been backpacking since I was 17.

    Warm & Soft

    Posted by Douglas Hea on Feb 12th 2018

    Wearing them for the first time today, they are very soft and warm. So far so good. I have some of your other socks and I enjoy the built in arch support they have. Maybe that could be added to this new model. Just a small recommendation.

    Best Socks I Have Ever Owned!

    Posted by Beverly Whitman on Jan 12th 2018

    I wish I had known about this brand when working in steel toed boots. I love these. They are soft and keep your feet very warm! I purchased this brand from a recommendation from my grandson, who works in a steel mill. He had so many foot problems until wearing these, as they keep your from blistering and peeling. I also bought my son some. He also had problems with sweaty, blistering feet. I'm planning on getting some for my husband. I also love the fact that they are Made in the USA!
