I bought these for a trip.  When they first arrived, I didn't think I would be able to wear them, but after experimenting with the lacing and wearing them for about an hour, the back ankle broke in considerably.  The first day I wore them all day, I did have a sore spot on the back of my ankle, but they weren't bad enough for me to go back to my room and change shoes.

They were sufficiently warm (it was about 7 degrees, and I wore them with one pair of thick socks), and the liner makes the boot very comfortable.  I typically wear a 6.5 (occasionally 7) in women's shoes; I ordered a 7, and they fit fine.

I did slip some on ice, but they were great on snow, pavement, and snow-covered pavement.
