Undergoing plantar problems right now.
My exercise regime is a combination of climbing and running.
It’s just like a sole coming off your shoe. High doses of aspirin around the clock, rest and when you have to walk, don’t flex. Walk just as if Elmer’s glue is holding the soles on your feet and you have to be careful to let it set.
Try Vionic shoes. My husband has had bouts of severe plantar fasciitis and he swears by those shoes. They have a very pronounced arch support.
