Why do you wear shoes of one size and one size?

Wear shoes of one size and one size, because:

1. Our feet will have different sizes.

In reality, everyone's feet will be big and small, only a little different. This is caused by the gravity of the earth and the position of the heart. People run counterclockwise. When running a corner, their right foot will exert more force to adjust their balance and turn the corner smoothly. The utilization rate of the right foot is greater than that of the left foot. When people walk, they will subconsciously exert more force on their right foot, and they will develop faster if they use it frequently. So relatively speaking, the right foot is generally bigger than the left foot.

3, in fact, many people not only have big and small feet, but also have big and small hands and cheeks, but everyone does not pay special attention.

The above answer is to rule out the difference of shoe size, why do you wear shoes one big and one small?
