I bought my first pair of MBTs a few months ago to wear to work and on weekends.  Then I bought another pair of MBTs.  Then I bought a pair of Sketchers Shape-Ups for weekends.  The Sketchers are much more comfortable and seem like they will last much longer than the MBTs, and they are not nearly as ugly.  On my first pair of MBTs, the elastic that connects the leather straps over my arch to the side of the shoe is fraying and coming apart.  The second pair of MBTs, while the same size as the first pair, are much too small in the toe area, especially on the right foot.  I am in pain if I wear those for too long.  The Sketchers are extremely comfortable.

People have remarked that my posture improves immediately when I put on the MBTs or Sketchers, and that I seem younger when I wear them.  I already loved to walk, but I can walk much farther in the Sketchers without any kind of foot pain.  It seems I get less fatigued walking in Sketchers than my normal tennis shoes.  I am losing weight in my thighs, butt, and lower abdomen.  I am almost down a pants size.  However, I have started eating Fucoprotein bars for breakfast when I am at work, so that might also be part of the reason for the weight loss.
