They really do! I used to wear them all the time before I moved to the US, these are a pair out of the few remaining since back then...but fret not! I just placed an order for a bunch of them that should get me to my old age (not far anyway).
On a more serious note, there are several advantages to wear these socks, mainly athlete's foot prevention and improving blood circulation, for you cold feet out there.
They do feel a little weird at first, but once you get over ii you really have a new appreciation for your feet. The reason I stopped wearing them was because availability and I moved toward thinner fabric due to the dress code at work. Now they make them for running, cycling, formal etc. so I'm back swinging, bay! Incidentally, I ordered them from the UK...
