You could always wear nothing at all. That might help. I know it would work for me =)

Actually my Mom had foot/ankle problems for a while. I think she ended up using crutches for almost 3 years. Not a happy thing especially when you live in Colorado and are very active. Eventually they ended up opening her ankle up and scooping out a lot of goo. Since then she has climbed 14,000 ft mountains, built a house, cycled, hiked most of the Colorado trail, and run a marathon.

It was tough, but she came through okay.
