The insole and the shoe must form a unit
with the level ground. Whether the foot is neutral,
in pronation or supination, is of no significance.
When insoles are made of solid material,
their length and shape are important. It is of
particular importance with handicapped patients
that the insoles are kept somewhat longer
in order to reduce the risk of tilting sideways.
This pronatory support, especially in the forefoot
region, gives the patient a feeling of security.
The correction of the talipes valgus should
be differentiated from the correction of the talipes
varus. With talipes valgus, the rear of the
foot should be supinated and the fore-foot
pronated in order to achieve a rotation of the
foot. With talipes varus, this is not possible.
Here, the whole foot must be pronated, i.e., the
rear- and fore-foot must be included in an homogenous
correction
