I use rubber boots, and I am very careful as to where I wear them. I do not drive with them to my hunting area and only put them on when I am ready to hunt. Before I put them on I will spray them down with some kind of scent eliminator (I have used many different brands, and have never been able to determine one better than the other).

I also from time to time will give them a shower in scent free soap before a hunt and let them dry outside.

Again another vote for not being a fan of cover up scents. I try my best to not let deer know anything has been through there, unless its a little doe or buck urine on some scent bombs.
