I like these socks a lot.  I wear them with work boots, usually for a 12 hour work day.  They are thick and strong, but not rough.  I have a few pairs of the white Carhartt crew socks, and I don't like them as much.  I think they have more cotton, and as they shrink they seem to get less pliable and friendly to put on.  These feel good, look good, and I fully expect them to last a long time.
