I read about MBT shoes, and their unique soles made for walking, but felt the price was too high for me.  I  found two pair for a great price on Amazon and bought them and boy am I glad I did.  I love the gait, and the balance benefits, and am sold on the sole design.  The construction and quality are excellent-- much better than the commodity shoes.  Styling is a bit sedate, but it's fine with me. Very satisfied.
