My girlfriend bought these for me for my birthday. I must say, i love them. I have worn them a lot, and they are SO comfortable. I didn't have to break them in at all! They fit true to size. Also, they truly are waterproof. I filled a bowl up at my house and stood in it...nothing! They have incredible grip at the bottom, walking on ice the other day, not one slip. They look awesome, which is always a plus. The only thing i can say about these guys is, make sure you have socks that match the heigth of the back of the shoe. They will rub, but it's very easily preventable! It's a fantastic buy...i promise!
