I have tried Earth shoes, Alegria, and a host of other high end shoes for my job in the hospital where I stand 9-10 hours a day.  These, by far, are the most comfortable...ever!!! These shoes also are must for those with narrow feet, and they feel snug...like a custom made pair of gloves for your feet!! Trust me...I am a shoe snob when it comes to my shoes used for work, because my feet are my base for the long hours in the hospital.  I am forever a MBT fan...particular Fora,
because they fit my narrow feet to a tee!  The price on Amazon was an extra bonus at $48!
