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.

Extremely comfy!!!

I’m from Alaska and these boots are amazing!! I’m ordering a second pair. Cute for the office, but also 100% keep your feet warm from Snow or water. These are so Comfy
