answer:I like the ProFoot inserts for Plantar Fasciitis. In my case, I have it bilaterally, and it is a chronic condition resulting from rheumatoid arthritis and exacerbated by being overweight. I bring the inserts with me when trying on new shoes. Try the inserts with your current shoes – the elevation of the heel might help where the shoe hits the back of your Achilles. Also, there are anti-chafing balms and powders that runners use, as well as blister patches from Band-Aid and similar brands that might help.
