Everyone walks and runs every day. Each person’s posture is different when doing these exercises. When running, the foot’s twisting is often ignored. It is called a gait cycle that the process of the feet leaving the ground to reach the ground again. When the foot touches the ground, our feet will naturally make a slight internal rotation to reduce the impact of the ground. This action can evenly impact the impact of the ground on the entire foot. Under normal circumstances, the thumb and the second toe will bear a little more pressure, so the main part of the sole is the heel and the middle of the toe.
However, if the angle of pronation is too large or too small, so-called eversion and inversion. Here “outer” and “inner” describe the relative orientation of the foot. When the foot is eversion, the person’s foot will focus on the inner side of the foot and the big toe. In this case, the wear on the inner part of the toe is more obvious. Conversely, for people with inversion, the sole of the foot is near the little toe on the outside of the foot during exercise, and the corresponding part of the toe wear is on the outside of the feet.
