Landau Invigorate

I start nursing school in the fall and had to get new shoes. At work as a scrub tech I wear Crocs for my 12 hour shifts, but I can't wear them for school. I bought the Landau invigorate and decided that I would wear them at work so that I could break them in before school starts, but still have my Crocs for backup. The first night was ok, a little aching, but nothing terrible. The next night I went in and within 3-4 hours my feet hurt so bad, mostly the balls of my feet. I immediately put my Crocs on and there was no more pain. I will live with what I bought, but man I am gonna miss my Crocs.
