This is my second pair!  I also purchased the brown ones about 2 years ago-still in very good condition.  They're very warm, cozy, totally water proof (I've put these boots to the test) and above all super comfortable.  I usually wear a size 7 - 7 1/2, and after reading some reviews to purchase half a size to a size bigger, I went with an 8-glad I did to make room for thick socks.  They're awesome!!!
