Tim, I'd actually agree with you and I mostly don't have to deal with moisture during my September hunt. However, one rain storm and every pair of boots I've had gets soaked and takes says to dry out. I do want good water proof boots for the later hunts though. In September a wet boot is uncomfortable at the most, but in deep snow, you can't be getting wet.
ETA: In fact, last year I brought a pair of Vibram Five Fingers just for stalking, but I had a bad pair because the top split all the way open after only one day of walking around.
