I do wear them but, like Greg said, they are not foolproof. I was filming a bowhunting friend of mine last year. He has a few acres right in the middle of the town he lives in that is crawling with deer. We were only a few hundred yards from his house. His wife got up that morning, not realizing we were hunting in the back yard and let their yellow lab out of the house. The dog came out, hit our scent, and followed us step for step to the bottom of our tree. He walked in a circle for a minute, having obviously lost the scent, and eventually looked right up at us. Both of us were wearing Scent-Lok and rubber boots. I think both products work to some extent but when conditions are right,nothing is going to keep a deer from smelling you. I still think that rubber boots are a cheap investment for what they can accomplish in certain situations.
