I wrote a review under the Men's Bogs boots and have repeated it here for the benefit of the ladies:
We bought a first pair for my husband and he found it really comfortable, tough and had lots of wiggle room inside the boot. Since my husband has flat feet and need a lot of room in the boot, we bought him a boot that was one size up. We tested it out in the bathtub with running water gushing over the boot and stood in water up to about mid calf deep for at least 10 minutes and our feet were absolutely dry. No seepage whatsoever.
I bought a pair of the same BOGS boots for myself in a women's cut, and selected a size in accordance to the sizing charts (measure your feet and then match them to the size charts for better accuracy). I found my boots true to size, with some room in the front toes. The lining is comfortable and not hard at all, and I like the neoprene around the calves, and the neoprene parts can be folded down if you do not like having the boot on a high cut all the time. It'll be useful in wet conditions with the pants tucked in. They are quite heavy and solidly built, feels good although slightly clunky but I do not feel clumsy in them. The traction has yet to be tested in wet icy conditions, but it did not feel slippery in the wet bathtub when I tested my boots in (caution -do not try this at home unless you take great care!).
