I would give the rating 5 stars yet I have only worn them a few times, so need more time to truly experience.  They are very well made and do not look "clunky" in my opinion.  They are extremely comfortable and plenty of room for my calves and feet.  I heard MBT was going out of business, so really wanted to get them. MBTs are the only type of shoes I can wear that do not hurt the bottom front of my feet. I have numerous pairs of MBTs and have been wearing them for years. You have to like the rocking of the shoes and be okay with balance. If I did not have trouble with my feet, I wouldn't end up spending so much and buying MBTs. Yet, since I do a lot of walking, and love walking, I am happy to find shoes that I am not in pain in after 1 hour. I hope the boots will be the same, but I have not yet walked more than 1 hour in them, so cannot tell at this time. So far, very comfortable.
