I wasn't sure about these boots at first, so I wore them around the house for a few days before deciding to keep them. Now they are my favourite boots. They are so comfortable, no breaking in required and super warm. I'm usually a size 6 but got a size 7. I have lots of room but the boot stays in place nicely around the ankles which is great. I love that I don't have to worry about slush puddles while walking the dog.
