For extreme winter weather, the Men's Arctic Sport Tall Boots style ASP from The Muck Boot Company is a great choice.  The rubber uppers are waterproof and have a stretch-to-fit top to keep out the cold and snow.  The fleece lining and extra thermal foam underlay will keep your feet warm in frigid conditions, while the rugged outsole will keep you from slipping.  This is Muck's premier boot for winter!
