These are absolutely fantastic.  I am on my feet for 8 hour days in a busy kitchen, on hard floors.  I've been wearing hiking socks but all in the midweight range - nothing this heavyweight.  My feet usually ache big time by the time my shift is up and I thought these might be worth a try since they were getting excellent reviews.  I wore them for the first time yesterday and WOW, what a difference.  I barely sat down the entire day and my feet felt great the full 8 hour shift.  First thing I did this morning when I got up was order a few more pairs.  If you are on your feet a lot you owe it to yourself to take care of them.  I've never worn socks as comfortable as these in my life.  Yes they are more expensive than some but the way your feet will feel after a day in these is more than worth it.  Highly, highly recommended.
