This is an excellent product. Much better than the hard plastic ones found at most stores. I am very happy with it and highly recommend it.

They are very tight to get on, and even feel like they might not hold my foot well, but when I do finally manage it, I'm pretty happy with this product. The bottom of the boot is a bit narrow for me, so sometimes it hurts at an angle on that edge between my big toe - but that's more because it's getting snug. Other than that, they're great -- warm, waterproof without having too much bulk or bulkiness to them, comfortable on long days walking around campus in snow, etc.
