Not waterproof as advertised.  I wore them for many months when there was snow, which was fine.  I did note that it seemed to leak a little during those wearings.  But this spring when we had some cold, rainy days and I was caught in a downpour for a good 10 minutes, my feet became soaked from rain coming down - - I did not step in any water puddles.  It would have been one thing if I had waded through several inches of puddles, but this is not the case.  These boots became soaked on the inside from rain falling from above.  Very disappointing.  Maybe it was this pair only, but let's put it this way, I do not plan to buy another pair.
