Little boot shop in the Mission.
It seems there aren't that many places to buy cowboy boots in SF. But this place seems pretty decent, and the price is right. Men's selection of boots is on the left side of the store, women on the right. And the selection is pretty fair. In the classic cowboy boot department, they had Tony Lomas, Durango, and some other brands from Mexico of which I can't recall at the moment. The salespeople speak both English and Spanish.
