I'm not sure if I have this or not but if I wear thongs or sandals for a while my toes will start hurting. I'm sure it has something to do with my arch. I know that my mom has to buy arch supports and she puts them in all of her shoes. I bought some Dr. Scholls shoes with air-pillo gel insoles and they've really helped me a lot. I hate wearing shoes when I'm at home though and I mainly walk around in my socks or slippers.
