I’m experiencing some of this myself. Flat feet runs in my family. Well, it doesn’t exactly run, because I’m unable to run. I walk a lot, and I began developing a form of arthritis in my left big toe a few years ago. I’ve had to train myself to walk a certain way to avoid causing discomfort. I use orthotics, but it only helps so much. Sure, I could get surgery, but I’d need months of recovery and physical therapy, so I’ve been avoiding it. I’m not sure when I’ll have the time and motivation to try to take care of it.
