I decided to buy a pair of the Santoni shearling-lined boots and I'm pleased I did. The shearling lining extends right down to the toe (top and bottom) and they're very comfortable. I've worn them twice since I took the photos and they've received several compliments. They're kind of hard to miss!
I got them from an Italian seller on ebay for what seems to be less than 50% of retail. Well worth it. They fit just about true to size.
