How Adding a Rearfoot Varus Wedge Helps Support High-Mileage Runners
When high-mileage runners experience shin splints or inner arch strain, standard footwear alone may not provide enough structural support.
Customising heat-moldable orthotic blanks with a rearfoot varus wedge allows podiatrists to fine-tune alignment and address specific areas of overload.
Why Use a Rearfoot Varus Wedge?
A rearfoot varus wedge is added to the heel section of an orthotic to help control excessive pronation and correct rearfoot positioning. For runners putting in high weekly distance, this extra control helps redistribute impact forces, taking unnecessary stress off the shin muscles and the medial longitudinal arch.
Tailoring Support to Individual Foot Mechanics
In this customisation, the heat-moldable blank is first shaped to the patient's foot in a neutral position using heat. A firm EVA wedge is then laminated to the underside of the heel, ground down to the exact rearfoot angle required, and trimmed to avoid sensitive areas under the arch. This targeted approach delivers stable rearfoot support without causing irritation through the midfoot.
Key Steps in the Customisation Process
- Heat-moulding the orthotic blank directly to the foot while held in a neutral stance.
- Laminating high-density EVA material to the underside of the heel area.
- Grinding the wedge to match the patient's specific rearfoot varus angle.
- Ending the wedge before the mid-arch to protect against distal arch pressure.
