My ex has very flat feet. He found that the only thing that helped him was to wear shoes with flat soles.
Have you tried that?

Hi,
Have you tried stretching excersises? Maybe physical thrapy might be able to help with the leg issues? Good luck!

@Aronia I don't believe so, I've been using the shoe inserts that I got from the podiatrist, I'm not exactly sure what flat sole shoes are and I probably don't have any but I'm curious how they would help with having flat feet.

@Jonsparky I used to go to physical therapy for my knee as I mentioned in my post but I was never able to finish because my insurance would not cover it unfortunately.

I also have flat feet and I can imagine how do you feel. I think your foot pain is caused by the shoes you wear, try to find other orthotic shoe inserts. I am wearing only shoes that are suitable for flat feet and I don't feel any pain. Moreover, sometimes I wear even high heels. I found on https://flatfeetcomfort.com/how-to-wear-high-heels-with-flat-feet/ interesting information regarding what kind of heels should wear a person with flat feet and it helped me to choose the right pair of shoes. So, I think you have to buy other shoes or in case your pains are getting worse, better consult with a doctor.

I have flat feet and very bad arthritis in the feet and ankles and very flexible joints in my toes. I find that I need very very cushioned soles of the shoes with more of a lower but good arch support. If the arch support is too high, it hurts. If the slope of the shoe is too high from heel to toe, it hurts. I also have one bad knee, they say it is arthritis but it is getting to be bone on bone in 3 areas. I have found several things in my journey to managing this pain. My feet love rocker type shoes but my knee doesn't. I have MBTs in the highest sole level and my feet feel good but my knee hurts so I have them in the mid level and lower level and these are better on the knee. I have Drew brand shoes which have a firm shank in the shoe and are best for my ankles and feet but not my bad knee. I just purchased Orthofeet athletic shoes and the heel area and arch support are excellent but they aren't great on my toes. I wear a different shoe every day. I have good arch support over-the-counter insoles even in my slippers/house shoes. Your custom made orthotics may be worn out by now and that is possibly why they hurt. Athletic shoes wear out in about six months of usage. I wear a different shoe every day. I can't walk or stand for long activities before my feet start hurting. There are many many other good brands: SAS, Vionics, Apex, Altras, Gravity Defyer, and on and on. Lastly, I went to an MD foot doctor first on the recommendation of my BIL. That guy was a qwack and misdiagnosed me. Then I researched orthopedic MD doctors in my area and found a great one. First visit, he diagnosed my problem by doing a thorough examination with his hands on my feet and then watching me walk barefoot, we did an MRI and that confirmed what he said. I had to have surgery to correct this issue. He told me that the first problem is easy to diagnose and is common - so I really was even more angry at the first doctor who told me something totally BS and didn't even do an MRI! It was this second doctor who further diagnosed why my feet hurt so much and said he thought I had arthritis of the feet besides the issue needing surgery. I never even knew this was a thing. So my point is, not every podiatrist or even an orthopedic foot doctor is skilled enough to solve your problem. Try different shoes (walk around on carpet so you can return them as unused if they don't work). Make sure you have a finger's length at the end of the shoe between the toe and end of shoe. Make sure they are wide enough or narrow enough.

I have flat feet and to be honest hate wearing shoes. But like others have mentioned, shoes can make a huge difference if you don’t wear the right ones for your foot shape and flatness. For me, I wear keen, sketchers with gel soles or shoes that have some kind of support that conform to my foot. I have also had orthotics made using an imprint of my feet. Once you find a brand that works for you, try to stick with that shoe type. Best of luck.

I have flat feet too. Mine is really weird because in my right foot I have absolutely no arch no matter what I do. When I was in like 4th grade I did physical therapy because I had really bad knee pain. Turns out I had flat feet. I was told to find shoes with good arch support and to get arch supports. A few years later the pain came back and was worse and I also sprained my ankle once and the again. I got custom orthotics a few times. Fast forward to current day, my right foot s still severely flat-footed no matter the orthotic insole I use. The support under my foot is not good enough, and I need more support on the sides of my foot. My left foot has an arch, it now seems to have too high an arch that my foot always rolls outwards which causes severe pain to my ankle which was sprained. I also have chronic ankle instability. Asics have special brands of shoes that are made for people with flat feet which are really comfy I think. I have noticed for me personally that I can't wear anything but sneakers because of the pain, and I also use KT tape to help stabilize my arches and with my ankle pain. But with my extra helping of issues, my pediatrician is having me see a PM&R, which stands for Physical Medicine and Rehabilitation Specialist MD. It might take years tbh, and I am trying to convince my doctors that a pair of AAFO's would benefit me for my feet. But if things are still rough, just make sure to stick up for yourself and continue to explain your concerns. We shouldn't have to be dealing with so much pain all the time, don't give up until you have tried everything. Best of luck!
