Sorry to be late chiming in... I have owned a pair of the 12" hunting shoes for 6-7 years. For me, they make the perfect winter boot (I'm in central Maine) with double wool socks for most conditions. I keep the leather well maintained with sno-seal (any beeswax-based treatment should work fine), and it makes them quite waterproof. I have even used them on a few fall canoe trips where I'm in and out of shallow water quite often and it's too cold to wear light water shoes.
To echo a couple of the points above, my pair is definitely a size bigger. I bought my standard size and if I don't wear double wool socks, they are loose. IMO, they are also not great for long foot treks. I'll have to look into tenkara's idea of super feet.
