These sandals have saved my feet.  I work in healthcare where I'm on my feet, on concrete, for 10 hours a day.  Some days I'm limping by the end of my shift.  Then I bought these sandals.  Not gonna lie; at first the nobbies hurt my feet.  As I wore them more and more they began to do their work and now I live in them when I'm home.  If I could get them in more colors, I'd wear them to church, lol.  Seriously, they are fantastic.  Highly recommend.
