I wouldn’t use orthotics to ‘solve’ this problem. Do you want to be dependent for the rest of your life?
Walk around barefoot more. Wear flat shoes with thin soles. Be mindful of your feet, the muscles in them, how they move.
Make sure to activate foot muscles that are sleeping. Play around with all the movements that feet can do, find the muscle memory, find stability.
Pronate, supinate, bend, flex, up, down, in, out. Everything. Your toes also. Walk around on your forefoot, walk around on your heels.
I hope you see why this approach is superior, and that it goes well for you!
