It's About the Socks
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...

Beyond Outstanding Fit and Comfort!
Honestly by far the best sock I have every tried. I am quite particular in the products I choose. This sock caresses every part of the foot perfectly. The ankle portion doesn’t bunch up one bit and remarkably without much of any pressure (and I have larger than average calves).
The thread also holds up really well, I still wear my first pair regularly thought the winter months. It’s the 3rd year and they have had very little thread loss, most wool socks will barely make it through the season.
I have tried socks that cost twice as much but don’t compare in comfort or performance.

Blue flame etech
Incredibly comfortable and warm. Makes wearing running shoes in the cold very comfortable. I am about to get my sock drawer reset to almost all ecosox. Every ecosox type I have bought has been nothing but great for comfort and wear.

Blue Flame is hot hot hot
I was honestly not expecting how warm these socks actually keep my feet. Love them and excited to get them out in the woods for winter adventures.
