After washing, these socks were too small for my size 10 feet.  They are supposed to fit up to size 13.  The instructions say they should be washed before using, and they smelled a little funny so I thought that was a good idea.  I laundered per instructions, cold water, medium dry. I was very disappointed when they were too small, and of course couldn't return them because they had been washed.

I noticed that another reviewer found them to be too big.  Maybe they have a quality control problem with sizes or labels.

The fabric feels nice and the laundry did eliminate the smell.  But accurate sizing is a pretty big deal, no?
