I'm on my feet a lot, and I have a bad back (which complicates things).  These shoes are extremely comfortable and they provide great support.  I can wear them for many hours with no fatigue.  This is my second pair - I think I've become a sold fan of Merrell shoes!  I wore the last pair almost every day for a year and they are still in great shape.
You won't be disappointed.  And, your feet with thank you!
