When a 'Rearfoot Varus' is present, then occasionally extra wedging is needed to enhance the controlling aspect of the device you are using.
A 'Rearfoot Varus' is defined as the combination of the Subtalar Neutral and Tibial Varum components which is the Neutral Calcaneal Stance Position.
1) Position the foot in the neutral calcaneal stance position (NCSP).
2) Wedge the rearfoot to the NCSP angle using the rearfoot wedge that is suitable.
VASYLI Rearfoot wedges have a 2° inclination and are made from firm (red) density EVA for maximum effect and long-term wear.
Wedging becomes important when dealing with any pronatory condition.
Rearfoot wedging itself is necessary to change the timing of the pronatory phases and to help control the level of excessive pronation present in most of these conditions.
For smaller sizes (XS) the rear foot wedge (RVR) may require trimming. Align the wedge with the start of the arch profile Trim rear of wedge as shown in the photo's.
