I was hunting winter boots for a while to finally replace my old ones and I finally found them.
These Keen boots have a great feel to them and seem to be built of quality materials. Once you try them on they are very comfortable and there's enough room to wiggle your toes (if you prefer/like/need/want that). The rubber sole construction/material extends to half way up the boots providing water proofing and protection for your feet. They are well insulated, and although may be a little on the heavy side, they're still manageable. Really happy with this purchase.
