Biomechanical dysfunction of the feet includes fallen arches, over-pronation or supination. There may be several reasons for a person to develop these problems, this includes weakness in the muscles of the hip or knee, or tightness in some of the joints or muscles of the lower limb altering the way you walk or run.
Biomechanical problems of the foot can be effectively treated with orthotics (special insoles) that provide biomechanical support and help feet to function more efficiently.
The most effective orthotics are those which are custom made to fit your foot, but in some cases non-prescription heat moulded orthotics or insoles can be used.
