I started in fixed gear after a get off on one of my Ducatis. My right foot was pretty much ruined and I was off my feet for almost a year. My doctor told me to try fixed to rebuild my leg. Worked great, with freewheel you can "cheat" and coast. Riding my fixed is like having a drill sergeant along for the ride not allowing you to coast pushing you harder. This is my foot now.
