I have a pair from several years ago from Bare Traps that has served me very well. I had the zipper replaced a couple of years ago, and they are still going strong.
I just bought a very nice pair of snow boots from Bos and Co. (Nordstrom) a couple of years ago. They were pricey, but they are very sturdy and should last a long time. They really crunch into the snow due to the deep treads, so they're not slippery. They are super warm.
I haven't tried Blondo's snow boots (I assume they make them), but I have worn their weatherproof booties, and they are very secure also. I would look for deep treads on the bottom.
