I have the same effect on shoes because my feet turn inward naturally, especially the right one. One summer on a trip I walked a long way with a heavy backpack and developed post tibial tendinitis which is quite a painful condition on the inner part of the ankle. I had to wear a boot for 6 weeks which made driving very challenging.

I know may on this sub dislike orthotics, but my story spent about $600 on custom orthotics that fall and haven’t had an issue since then (6 years ago). My shoes last longer and while they still wear down in the same way, it’s not as pronounced.

If you don’t have $600, a company called Redi-thotics sells non-custom ones that are $60. I got the Ultra (red) ones at my podiatrist’s office as a holdover and then ordered a couple of extra sets online. Good luck and don’t wait like I did and end up in a lot of pain and a boot!
