When the heel is too low, the net weight of 60% of the whole body weight will be pressed forward against the heel when the foot touches the ground, and the submitted impact force will cause pain in the ankle, knee, hip joint and waist. Wearing flat shoes for a long time will continue to accelerate the decline of plantar tendons and bone tissue, causing heel pain.
Feet bear the weight of the whole body. When the physiological inclination of the arch changes, it will seriously affect the bearing function of the arch, its walking, running and the maintenance of human posture. The total contact area between the longitudinal arches on both sides of the arch and the road surface is large, which improves the reliability of the body when standing. The longitudinal arch on the inner side is more curved, which makes the foot more malleable and can offset part of the impact in sports.

Transverse arch is the metatarsophalangeal joint produced by phalanges and metatarsals in the anatomical map of foot bones. In the whole process of fitness exercise, the extension and flexion of metatarsophalangeal joint make the interaction force move forward.
When people walk normally, each foot has to go through the whole process of stepping (the foot follows the ground), rolling (the center of gravity moves forward and one leg is shaking) and pedaling (the metatarsophalangeal joint is bent and the toes are pedaled off the road).
The arch of the foot transfers the force from the knee joint to the short metatarsal bone through the talus (the bone bearing weight and articulated with the calf bone at the ankle), and then to the ankle fracture, thus buffering the impact of the human body and protecting the brain and internal organs of the human body from fluctuation.
