Well, I had to break down and buy some snow boots but I didn't want to break the bank.  When these went on sale, I jumped on it.
First of all, they are SUPER light weight, the fabric is almost like a parachute material. The inside looks and feels like lamb wool and the top edge has a nice faux fur (both are actually polyester).  They are incredibly comfortable, with soft inner soles and good cushion and flexibility.  Did I mention they are light!?  Great traction on the sole.  Contrast laces look awesome. not bulky.  W A R M.
overall, a great purchase.  They do run a little big. I bought a 10 and they will fit with my big wool socks, but I really won't need wool socks with the warmth provided by the boot.  size down about 1/2 if you plan on wearing regular socks.
