Bamboo charcoals has superior absorbency power. Odor? Sweaty feet? Work in a damp or wet environment? Let the bamboo charcoal fibers sown into our socks absorb all of that for you. 

The bamboo charcoal is antimicrobial: this means that the growth of the bacteria that build up around your feet is inhibited. Result? Less stink, less potential for athletes foot or infection.

Bamboo charcoal emits far infrared rays. What's that mean you ask? During the heating process when the bamboo becomes bamboo charcoal, the material absorbs far infrared rays, and later emits them when warm.

The short version: Your feet emit body heat => BSBF socks emit far infrared rays => *science happens* => you get better circulation of the blood in your feet and ankles. Our bamboo charcoal is woven throughout the entire sock, not just the sole or ankle, to give your superior circulation.
