I used to wear MBT shoes all the time.  A shoe much like this one has been discontinued.  I walked 7 miles on cobblestones and I often travel with such a shoe--very comfortable.  I was looking for a substitute for the MBT shoe that I loved and which cost about $255 per pair.  This one is reasonable in cost and feels the same.  The top seems even more durable than the MBT one and it doesn't get as scuffed.

My only critique is that it doesn't have much arch support.  I solved that issue by buying some cork insoles from a really good shoe store.  They cost almost as much as the shoe, but now I have extra padding and a great arch support.

I have a right foot that is misshapen from an accident 15 years ago.  It healed with bones going in all directions and cannot be fixed.  Without such shoes I am in terrible pain.  With them, it solves my issue.

They are also easy to get off and on in airport security with the velcro strap closure.  I am buying a second pair right now so I have a backup.
