I have wide feet, so I got a pair that are "wide". Let me tell you, they are WIDE!! lol So much that I had to wear 2 pairs of socks with them, but they are warm, and comfortable. And the zipper on the side is nice because if you're like me, you slide your shoes off, and then have to untie them to put them back on, but the zipper makes it so you can just unzip, and slide your foot in and not worry about the untying.
