Anything I can do for over pronation?

I have quite a bit of over pronation on both of my feet and I’m not sure what I could do about it. I have very high arches on my feet and from what I’ve read online it could be a factor to my feet pronating.

Is there anything I could do to fix my over pronation? I get shin splints and stuff because of it. For the past week I have just been balancing on 1 leg at a time while activating my arches and I can feel tension on my arches and calves but I don’t know if this would actually help with strenghtening anything.

Any help would be appreciated.
