Generally speaking, most people walk with their feet in a straight line (typically, like a model walking on a catwalk). In this case, the outer heel of the shoe will wear more;
If it is a eight-character step, every step is aunt-like, and the inner heel is seriously worn.
If it is mopping the floor, the forefoot wear will be more serious. ....
In fact, from the perspective of academic physics, people must keep the whole body balanced when walking, so the sole can't be completely flush with the ground, because the position of the sole is not on the center of gravity of the human body.
Everyone has this situation, so don't worry about anything. As long as you think your posture is good, you don't have to worry about shoes.
