Got these boots in black, just before a torrential two week rainstorm. I walked in water up to my ankles and my feet stayed dry and comfy!!  These are definitely waterproof.  Great lining too - my feet are never sweaty.

I got the 10 med and they fit my feet just fine - width and length are great.  I will say the ankles seemed a bit small, and didn't zip at first.  I tried them on without socks and walked around the house, then with very thin socks, zipping up a little more each time.  I've had this problem with all of my La Canadienne boots.  This is my third pair.  They eventually stretch enough to be comfortable and they look great.  I end up wearing them all winter long.

Can be dressed up for work, or down with jeans.  Was concerned about the suede on these, but so far it's held up.  The heel is slight enough that I can get a little bit more height, but not so high that I have a problem as I have a back issue and can't wear heels right now.  I feel that some of their other boots are hipper - but these are stylish enough and they win on comfort and keeping feet dry!
