I've been looking for a pair of classic, equestrian-inspired flat boots made of real leather and polished enough to wear to work as well as on the weekends -- surprisingly difficult!  I decided to take a chance on these and am so, so glad I did.  I'm not sure why other reviewers had issues zipping them up; my calves are fairly average-sized, I'd think, and I can zip them up with plenty of room.  I could have had them go even smaller for a tighter look.  I got them half a size larger than I would get for dress shoes, so I can wear nice thick socks for winter, and they'll fit perfectly.  The leather is soft and smooth, the Thinsulate lining is a great touch, and they're marked as waterproof too.  Great buy!
