Feet can change, but its not quick. I would suggest choosing progressively demanding footwear over time, or go barefoot as much as possible. Or, go very minimal but limit how much time you spend in them to a few minutes at a time to start, just walking, and make sure you stay within your capacity for a long time until you know where that line is. Coming off serious injury, it took me a year to wear minimal shoes comfortably all day.

But going barefoot or with minimal shoes is not magic, you will need to do other work to get to your goal. Its best if you can do a little bit every day. If you just strengthen from where you are now, you'll just be getting stronger within the limitations you currently have.

So once you have a footwear plan, I think its required to improve involved joint functions, the hips, tibia, ankle, midfoot, big toe etc. Those joints moving correctly will better enable you to have the right body mechanics to reduce compensation, and restore more natural foot function.

Plus you can get helpful benefit in those joints WAY earlier than you'll probably see improvements in your feet. And getting those joints improved first will better enable your feet to improve later. Strong feet start with strong hips. Take a look at the figure 4 position, and maybe over time if you have improved hip rotation, look into the 90 90 position.

(take a look at functional range conditiong, or kinstretch to learn more about joint improvement. Also lookup controlled articular rotations, pails/rails, hip CARs, ankle CARs etc.)

As for feet specifically, maybe consider this kind of work:

From my view, given these very few details, I would probably say that you should consider only running for a few minutes at a time while minimal or barefoot, for at least 3-6 months. Its so easy to do too much, too soon, and end up with a problem. And you'll have settled into some mechanics or compensations that will be much harder to switch later - as compared to getting some of that working in the right direction first.

Patience is your friend. Incorporate the right changes, work on your feet and joints, don't push too hard. For me I saw some first benefits in a few months, but it took a couple more years to really see the bigger changes come together.
