I mentioned it might be time for me to go a half size bigger to my podiatrist. He gave me a card to check out shoes store. After being evaluated the young man brought 3 pairs of shoes and a pair of socks. I thought there is no way that thin sock will work for me. I was so wrong. My feet had been burning and hurting for years. I kid you not...the moment the sick was on all the pain stopped immediately. I was in tears. My feet don't hurt at all now. Forever grateful for OS1st
