My hubby is on his poor feet for 12 or so hours at a time (at the hospital).  He has some kind of problem with his feet, and no other shoes work for him when he has to wear them for so long.  His old MBT shoes finally wore out after about 3 or 4 years.  Found these shoes on Amazon Marketplace for a great price.  We bought 2 pairs; one for now and one for when the first pair wears out it a couple/few years.
