Stand with your feet splayed and your legs straight. Why?

Because splayed feet, the formation of splayed feet generally comes from early childhood, such as standing upright or walking prematurely, which is easy to cause splayed feet. Because the baby's leg strength is not particularly strong, when standing or learning to walk, the foot will naturally increase the contact area between the foot and the ground, stand more stably, prevent falling, and form a splayed foot over time.
