When the outside of one's foot are forced to absorb the majority of the weight, bowlegs develop,
and the center of gravity shifts to the knees and the waist.
Naturally, physiological problems may develop in those areas as a result.
Feet
Pain and a difficulty occurs because the center of gravity leans outside.
Knees
Because of the bowlegs, the center of gravity crumbles, and a difficulty may arise in the knees.
Waist
Distortion occurs in the pelvis, and lumbago, or pain in the lumbar region develops.
