This is the first pair of MBT shoes I've ever owned, and I can honestly say that I will always have a pair of these unless the world comes to an end. They definitely work muscles in your legs that would never see any use in a normal pair of shoes. You can tell even when you're standing still that they are at work. They are very comfortable, so extremely well made, and very nice looking. My posture has improved since I've been wearing them, and my legs are definitely getting stronger. I would recommend these shoes to anyone.
