These boots were sort of an impulse buy... but one of my best recent purchases! I bought them purely to keep my feet warm but after 3 feet of snow in the Baltimore/Washington area they have come in quite handy!  I normally wear size 7 and ordered a 6 per other reviewer's recommendations. I am glad that I ordered one size down because although they seemed a little snug at first they did stretch out to a perfect fit quickly.  They are not waterproof so don't get them to keep your feet dry when trudging through 4 inches of slush (my socks got a little bit wet from that) but they are great for walking through deep powdery snow and keeping it out of your boots/socks.  Although they were a bit damp after spending hours outside in the snow they dried quickly with minimal/no visible water damage on the suede exterior.  These boots would be ideal for use in the winter with 3-4 inches of snow or just simply to keep your feet warm on a cold day.
