Rearfoot varus additions can be used to increase the inversion of the orthotic when moulding to NCSP (that is, when the amount of pronation is in excess of 5°).
Rearfoot wedges can also be used to reduce patient’s pronating over the arch of the orthotic.
If required, before heat moulding the orthotic, attach the addition to the medial aspect of the plantar surface using the double-sided tape. Then proceed with the heat moulding process.
