I am used to a lot of shoes being sized smaller than what they really are.  So, when I saw they had a 14 in this shoe, I grabbed it. However, when I put it on, it was bigger than any other 14 I have tried on.  Add the stretching that goes when you wear this type of shoe for a while, and they are hard to keep on.
All that said, it is still a good shoe.  Very warm and comfortable.
