I was a little worried when I first got these- my feet are a little wider than normal, but not wide enough to need wide width. They were quite snug the first few times I wore them, but after some breaking in they fit PERFECT. I did have to go up a half size from my normal 7 to a 7.5, but these boots are fantastic and I can tell I have them for a long time!

Get these! You won't regret it!

These are my go-to winter shoes! They are waterproof- I love them bc they don't look like your typical "rainboots"! Stylish- I get compliments everytime I wear them! Comfortable- first time I wore them they were tight through the middle of my foot, but after two wears I had them nice and broke in, now my most comfortable shoes!

So nice but not a good fit on my foot

I love these boots so much, they’re exactly what I wanted. Unfortunately, they are too big in the heel and flop, while too tight in the toe. I know the toe would stretch with wear, but can’t deal with a floppy heel, they pulled my socks down off my feet. I do have narrow feet. Too bad, I’m so disappointed! They seem well made and would go with everything. Comfortable, too, if they fit right.
