Many people have convex bones of one kind or another. In this case, you can't "cut your feet and fit your shoes"! One way is to buy some soft shoes, which are not easily deformed and uncomfortable to wear. Another way is to buy some hard shoes and wear them occasionally on formal occasions. The other thing is to keep your mind, and not too many people will pay attention to your feet. Don't worry, there are many more important things for you to do.
