I am seriously considering buying some Fuggs from Old Navy.

I'm calling them Fuggs because, obviously, they are Fake Uggs, and frankly, they are kinda fugly. But I'm not considering purchasing them for fashion reasons... I'm thinking of getting them because my feet are the coldest feet in the history of the universe. I walk 3/4 of a mile to and from work each day and my feet are already turning into blocks of ice before I make it to my destination... and it is currently in the 50s. Literally, my toes have been dead white the past two days when I've gotten home, and it is only going to get worse once winter arrives and we have temps in the 20s, or below. (Brrrr!) I feel like these might actually keep my feet warm on my walk. I own snow boots, which I would occasionally wear last year in the actual snow, but which I felt looked sort of silly wearing when it was above 30 degrees and no snow was on the ground.

What do you think... are these boots too fugly? Should I get them anyway and avoid frostbite?

On a related note, does anyone have any tips for what tights to buy that will actually keep my legs warm in the winter and not run? (As the pair I wore did today, while I was at work... grrr.) I've been checking out some of the options from Sock Dreams (I've gotten socks there before), but I think they might be too casual. But, I really need something thick and warm, or else I am retiring all my skirts and dresses until next May.
