A half size bigger than my shoe size fits comfortable.  I waterproofed them before wearing. I also ruined the appearance when I wore them, for the first time, out snowshoeing for an hour.  The suede is now worn off on the toes and a few other spots.  They kept my feet warm, dry, and comfy.  Still worth the reasonable price that I paid at Amazon.com.  I also purchased a pair from Macy's on sale for $20.00 more in brown.  I have not worn them yet but will keep them for going places where I am not going to abuse them.
