From the Research
For supination, the best orthotic is a lateral wedge orthotic with arch support, as it helps redistribute pressure more evenly across the foot and maintains proper foot alignment during walking and standing, thereby reducing strain on ankles, knees, and hips 1.
Key Features of the Recommended Orthotic
- A firm lateral posting (wedge) that elevates the outer edge of the foot
- A supportive arch component to maintain proper foot alignment
- Custom or semi-custom orthotics for optimal fit and support
Benefits of the Recommended Orthotic
- Reduces strain on ankles, knees, and hips by encouraging the foot to roll inward slightly (pronation) to counteract the supination tendency
- Improves postural stability, as shown in studies such as 2, which found that prefabricated orthotics improved postural stability in participants with functional ankle instability
- Can be used prophylactically or after an acute ankle sprain to reduce the risk of future ankle sprains, as suggested by 3
Recommendations for Use
- Break in new orthotics gradually, wearing them for 1-2 hours initially and increasing time daily
- Replace orthotics every 12-18 months as the supportive materials compress over time
- Consider consulting a podiatrist for custom-made orthotics or guidance on selecting the best orthotic for individual needs.
