The invention relates to a foot balancing device, in particular to a foot balancing device which allows the user to distribute the weight of the human body evenly on the foot when standing or walking.

With the development and progress of the economy, the opportunities for modern people to carry out manual labor are greatly reduced, which leads to the lack of physical exercise for modern people, so that the opportunities for modernized human diseases are greatly increased.

In addition to various types of civilized diseases, chronic pain caused by poor posture is more common in everyone. The main cause of chronic pain is the imbalance of skeletal muscles due to poor movements and postures. From the point of view of biological evolution, in the course of human evolution, human beings have evolved from four-footed crawling into two-legged uprights. In order to maintain the balance between the two legs standing upright and the two feet upright walking, the bones and muscles will reconcile each other and produce a substitute compensation function, so that the human body will not fall down when the two feet stand upright, and can be two feet. Continue to travel while walking upright.

However, the aforementioned substitution compensation function is an interaction between different bones and muscles. This interaction between bones and muscles may cause various undesirable movements and postures when standing or walking, and poor. move The posture and posture also make the skeletal muscle unbalanced, further causing the aforementioned chronic pain and various soreness.
