I wore my Patagonia rain boots for most of this Chicago winter.  My feet were toasty, but on very wet days, my feet got wet.  I wear size six, I bought this boot in size 6.  They are tight, but I like it.  I like being stylish, but for my commuter winter coat and boots I have no problem throwing that out the window for the sake of being dry and warm!  That said, I do like the look of these boots.  My feet are not as toasty warm in these, but I'm not complaining because my feet are dry.
