For many decades of outdoor activity and running, I never had foot problems. Then I did some work involving standing on a ladder, and that got a foot problem started. After a few months, I finally recognized it as plantar fasciitis. For some, it shows up in the arch area. For others, it is toward the heel. I immediately did the standard exercises with a frozen roller to treat it, and then I started using generic orthodics to improve the arch support. It's been three years now and the symptoms have not returned.
