I wear Russell Moccasins I have about 8 or 10 pair with a variety of soles and insulation...I have a couple of pair that are going on 20 years old. My favorite Russel hunting boot is the "Signature Series South Forty Bird Shooter" with a 200 gram thinsulate insulated foot bed.

If it's really wet I wear either Lacrosse or Le Chameau leather linned rubber boots...if it's really cold I break out the Mickey Mouse army boots.
