Every athlete understands that foot function is a very important part of their sport. Scientific literature, in the field of human biomechanics has documented the relationship, between placement of the foot and function of the entire body, for more that 20 years. Ultimately both optimal performance and chronic medical conditions have been related to the biomechanical movements of the foot, knee, and spine during weight-bearing activity.
Even though the importance of this functional relationship associated with placement of the foot during athletic activities, is clearly identified by science, medicine, and virtually every athlete, only two or three biomechanical researchers currently understand the mechanical forces involved.
The problem is somewhat complex, it involves the anatomical relationship of the lower extremity and the mechanical forces that result during closed kinetic chain function.
