I've worn these socks for many years and they were okay.  They are not the smoothest socks inside, especially near the toe area.  My recent experience with bamboo/rayon socks from Florsheim and Nautica indicate that the material in these Gold Toes is not the best for keeping foot perspiration under control or even keeping my feet warm or cool as appropriate.  I now strongly favor the Nautica tipped rib socks instead for about the same price.
