I live in a very cold climate so I decided to spend some of my Christmas money this year and get the real thing.  I also  bought spray protector because we get a lot of snow here.  These are beautiful!  I am wearing them for the first time today and they are so cozy.  Do buy a half size or even full size smaller as they do stretch out (they are suede, afterall) and I recommend the spray protector even if you don't get snow.  It didn't change the color of my Sand boots at all and it will protect them from any kind of external moisture.  That only makes sense when you are talking close to a two-hundred dollar investment.

UPDATE:  After six weeks, these have a hole on the top!  It is unmistakable and will only grow.  However, since the marketplace company these were purchased from only allows a one month return, I am stuck with a $200 hole in my bank account.  I have Ugg slippers and have had them for years with NO holes whatsoever.  I could not be more disappointed and will never shop from this merchant again!  Beware!  Even if you do want to return something to this merchant, you must have your ORIGINAL packing slip to do it and you will pay shipping to return.
