Query: Not what I was expecting when I asked for these for my birthday.

I have worn out many pairs of moccasin-type sheepskin slippers and had suggested a fresh pair from my wife. She got me these instead. They were a little stiff to get on at first, but were actually warmer than the moccasins I had been using--surprising in that the moccasins come farther up the ankle.My wife had read other reviews and was forewarned to order at least a half size larger. I would strongly suggest everyone to order a half or full size larger.They are very warm, and give me a more secure footing than the moccasins. The sole gives me good traction. The nap of the sheepskin seems just a squidge fuller than any of my old ones, probably why they are so warm.
