These shoes are not for everybody.  I have four pairs and sandles by MBT, but not everyone has the willingness to adjust their stride to compensate for the heavy, non-flexible, and curved sole.  Some styles are curved differently than others, so they affect the way your foot lands differently.  I have a bad back and as a teacher I must stand for long periods every day.  The MBT's have made it possible for me to go throughout the day feeling great.  The sole of this shoe causes you to remain off balance (not flat footed) diverting the strain from your back to your legs.  I particularly like the Kitabu style which looks like a traditional oxford as opposed to some of the other weird designs.  The leather finish is top quality.
