They're nice!  I like the look and the feel of the wool.  But I guess I can't have these.  I ordered medium for my size 10 W.  My husband wears a Men's size 8.5.  He has wide feet.  These were too big on both of us.  I was surprised.  I wanted a fit that would really feel like a sock and fit my foot, so i would feel sure-footed on stairs around the house.  But they are just a bit too long, and a bit too wide.  For my husband, they were just a bit too long.  So I have to return them.  I looked just now for a size small to order in their place, and the price is about $8 higher than for the mediums.  $37 for the mediums was already a bit high for me, for a slipper sock.  But $45 just feels extravagant.  So, yes, they are nice, the sole made to conform to a foot, so you have a 'right' and a 'left.'  But just too expensive, in my opinion.  So in terms of value, I had to downgrade by 1 star.

The sizing on these seems to be an issue.  I have not worn a size "small" in anything since i was about 19 years old.  A size 10 W shoe is NOT small.  If anything, it's large.  My husband has medium men's feet, certainly not small.  So until the sizing changes to be more standard, I'm guessing a lot of people return these.  If you have even a size 9 W, I don't think these will fit as they should in a medium.  Better get small.  This means they must sell several times as many smalls as mediums and almost no larges since most people are not giants.
