These shoes run REALLY small in width and length! I have fallen arches and was informed that these shoes would provide the best support for me. I have been having troubles with my ankle/foot and was hoping these would help. I wear a size 12 only because they don't make an 11 1/2. When I received the shoes I noticed they were a bit narrow, but thought that was part of the support for my arches. After wearing them for 3 days (unfortunately it took 3 days before the pain started), my foot/ankle was so sore I couldn't walk and my toes were sore from rubbing on the inside of the shoe. I went back to my old pair of shoes and the pain went away. I am really ticked that I spent all that money on something that caused me more pain, I cannot use, or return since I wore them for several days.
