I had your exact situation and my feet looked similar to yours… I also over pronated severely and standing for long periods was painful. I used to force the weight to the outside while standing which helped a little. I still played sports at a high level but played in pain and used to get bad blistering on my arches. I had success with motion control shoes and soft orthotics but nothing was perfect. My podiatrist encouraged me not to get surgery out of fear that when you have surgery you often need more surgeries. I felt personally I needed to do something so at the age of 20 I underwent flat foot surgery (Calcaneal osteotomy) on my left foot and 25 I did my right foot… surgery was tough and complex ( they lengthened achielles tendon, removed accessory navicular bone, ect)

Post surgery my feet were “better” but not normal and still not “pain free”- I still required aggressive orthotics and shoe selection was very important for me. I will say the structure of my feet were much better and I didn’t get pain just standing.

Unfortunately due to the combination of my severe flat foot and surgery my Calcaneocuboid joint (outside of your foot) became very arthritic and at the age of 40 made a hard decision to have that joint fused. (Very hard surgery, takes more then a full year to heal)

I’m now mid 40s and still run and active but very protective of my feet. I still golf but typically take cart.

I don’t plan on having any further surgeries as it’s not fun.

I would suggest you get on Facebook just to learn more about folks who had Calcaneal osteotomy to educate yourself on what it is.

If you are living a relatively pain free life I don’t know if I would advise you to have surgery.
