they fit a bit big so if you are a half size order down instead of up a size.  I have to say these are very, very confortable, however if you live in an area with lots of wind or static in the air you are going to hate these.  I can't even wear them for half an hour without getting progresively stronger zaps when i touch something.  I tried 100% cotton socks, heck i tried no socks, i sprayed static guard inside etc.  so now i have an expensive pair of boots sitting in my closet holding down the carpet
