Normal wear marks in relation to the centre of pressure
1.
Incomplete or abnormal ontogeny, resulting in bony architecture in
which the foot is not plantigrade.
2.
Abnormal pitch of any of the joint axes of the foot, producing
abnormal movement in the foot.
3.
Proximal abnormalities in the lower limb or trunk that result in
abnormal position and hence function of the foot, for example,
abnormal tibial or femoral torsion.
4.
Feet that do not adhere to shoe manufacturers' concept of a foot
that has normal dimensions, for example, a foot that has a
disproportionately long heel to ball measurement compared with the
ball to toe measurement will result in distortions.
5.
Traumatic changes to any part of the locomotor system, resulting in
abnormal function.
6.
Disorders that affect the muscle control or bulk of the limb, affecting
function, for example, cerebral palsy.
7.
Poorly fitted footwear that inhibits or alters normal foot function.
