These sandals look nice but they run narrow.  I purchased a 12 but I can usually wear an 11 1/2.  This scandal was snug even though I purchase a 12.  I wore them for the first time to the zoo on a hot day.  When I got home, my feet were sore and I had black imprints from the scandal on my feet and they were sore.  However, I did walk the entire day in them but expected they should handle it and they didn't.  I did not return these sandals only because I needed a black pair and they look nice on my feet.
