Had it flare up many times over the years. Most recently a new pair of work boots caused it to flare up. Threw them out and bought a different pr along with inserts from Spenco. And a pr of OOFOS recovery sandals for around the house. Plus good sneakers with the same inserts . Not entry level. After a few weeks I was and remain pain free. Still can get sore standing on ladders for a long time. I was barely able to walk before.
Wife has it and is not responding well.
Edit. It was a new pr. of Redwings that caused the flare up. Steel shank. Tried pulling out insert because there was not room to add one. New pr had a removable insert. Something to consider when shopping.
