I wore these shoes for 6 days straight on vacation to Montana, Wyoming and Colorado -- a vacation that included LOTS of outdoor activity, that had me on my feet for long hours.  The shoes were comfortable and provided good support.  I'm used to wearing lighter running shoes -- but these are a heavier duty shoe for what I needed. I wore the shoes on and off for about a week and a half before my trip to breka themm. . . it's a good thing, b/c the shoes did rub my heels and caused some light bleeding.  After a few days though, the shoes were well fitted to my feet and ready for vacation.  The grey is also a nice nuetral that works with a variety of clothes.
