My wife is crazy about these shoes as she was sold to the notion that it shapes up your legs and creates a firmer behind.  I bought her one of these shoes (the one with a strap, no shoelace) and she loves it.

Shopping with her at one of her favorite shoe stores is like going to a museum.  To make it short, I had to do something with my time than just loitering around.  I saw this black pair and I thought it doesn't look bad at all.  In fact, it is just my style, simple, just plain black, and not wailing in painful bright colors.  It is also light for its bulk.  I tried it on and flanked the aisles back and forth.  I fell in love in an instant.  It makes me feel much taller.  Suddenly my vision of the world is much wider, being able to see above the shoe shelves without standing on tiptoe is exhilarating.  I am at least 1-1/2" taller.  The good thing is that it does not look like an elevator shoes as the extra inches are tucked away inside the shoes.

They also call these shoes as balance shoes as you need to always shift your weight as the sole of the shoes is like the foot of a rocking chair.  You will be constantly moving hence it makes me a believer about the concept.  The first shoes I saw that were built like these were made by MBT, but just looking at the tag makes me and my wife just a window shopper.

And what is the only downside for me so far? One of my co-workers who know about these shoes asked me one time, "Hey, did your butt grow yet?"
