I have been listening to a podcast by Peter Attia about foot health, and the trend of cushioned athletic shoes since the 70’s boom. Cushioned shoes let humans increase the length of their gait and use their heel more in the walking/running movement. As opposed the using the forefoot, which is more natural. The solution is working toward more minimalistic shoes so that you move more naturally and the foot muscles strengthen back to their capability.
Maybe you are over-using your heel.
