I work 13 hour shifts in a hospital and these shoes are amazing! Ive worn them for a few months now and they are still just as comfortable as when I got them. My legs and feet don't hurt at the end of a shift anymore.
They are also really cute, I get complements all the time!

The only down side is they have no ventilation so your feet can get pretty hot. I don't really notice until I take them off, though.
