I'll be using these boots for outdoor work this fall and winter (Florida).  They are the most comfortable shoes of this type that I have ever owned.  They have a good style about them so that my wife won't complain if we happen to have lunch or something and I don't have time to change (or want to).  While being waterproof, somehow they seem to breathe -  a feat not easily accomplished I am sure.  Sizing is right on par for me.  Strongly recommended these if insulation is not a requirement for you.
