I wish I knew a little bit more about when/how you are falling, but I JUST figured out why I have taken so many tumbles over the course of my life. At almost 67 yo, after finally snapping my pereoneal longus tendon, my wonderful foot and ankle specialist, within :30 identified a congenital defect in my ankles. It’s called “cavus deformity.”

I could go on about it but the bottom line is, have your feet/gate/walk evaluated by an orthopedic specialist. Simple inserts can make a difference even if your problem is not extreme.
