From the tips of the toe to the top of the welt every XOSKIN™ sock contains RAPIDriCOPPER™ fibers to completely encapsulate the foot. RAPIDriCOPPER™ wicks and dries very rapidly while reducing the co-efficient of friction on the skin surface because of the unique US Patented PTFE molecules built into the yarn. The US Patented Copper yarn reduces bacteria and promotes healthier skin texture, skin tone and overall a healthier environment for the skin surface.
