Don’t waste $$ on insoles, socks or any of that other crap. I did-big waste of money at a “foot doctor”. Finally went to a guy that actually knew something. Fixed in less than 3 weeks, no issues since. Firstly, lose the heels on your boots - get good shoes with flats like some if the Redwings have. Second, find some stairs, place your toes on the edge and let your heel hang down off the back to stretch that muscle. About 2-3 minutes and few times per day. You should see improvement within a week.
