These are very good quality socks.  We bought them for all the guys in our wedding party for the big day.  Many of the guys have contacted us asking where we bought them so they could get more in other colors.  The top is tight enough to stay up but not so tight it makes the leg itchy or aggravated.  They are smooth and do not pick or get pill-y easily.  The wicking fabric really keeps the moisture and any odor down.  We've only had them for a few months, but they seem as though they will not be wearing out any time soon.
