I don't worry about the scent that I leave behind while scouting because I do most of my scouting long before season and the scent that you leave behind is gone within a day or two. Maybe try a cover scent on the bottom of your boots like racoon urine, or skunk scent. They're both powerful and should do a good job of covering your scent, just remember don't wear your boots in your truck or in the house, your wife will get really angry.
