I bought these as a gift for a friend.  She reported that they fit well and have good traction but that they are not as water-resistant as she had hoped.  I realize that if you do a Tough Mudder in these, that they will get soaked but I was wearing another pair of Merrell's that were way more water-resistant.  Just don't go for these if that is important to you.  Otherwise, they look pretty cool.
