I own numerous Carhartt products; and, these socks definitely don't meet their usual standards.  They run small, from the outset.  Worse, they dramatically shrink during the first warm-water wash and warm dry, to about 70 percent of their original size.  Worse, still, they develop large and visible holes after only two or three wearings.  They're not marked as seconds, irregulars, or rejects on the Amazon site; but, they should be.....!  Virtually anything else would likely be cheaper and better.  Check them out, before buying these.
