Planet Shoes (.com) has a 40% off offer on the whole store, including clearance items; I was noticing there are a ton of winter boots in there, waterproof and snow boots included. Kamik, North Face, Sperry, Bogs, Blundstone, Rockport, etc. The clearance items are final sale, no returns, but if you have a brand you know fits you well, you could get a really great deal.
