Ok. I bought my Protalus shoe inserts last week. Since I had broken my foot skiing over 50 years ago, I didn't expect much help. My Drs. have repeatedly told me how flat my feet are and how much I needed a GOOD shoe support. Well, I received my supports today, and all I can do is smile and tell you how wonderful my feet feel --after 50 years of suffering. These do work! My feet don't feel tired. They feel great. I even want to sleep with my shoes on tonight. Any questions? Ask me. I'm a real person! Thank you Protalus.
