What is the function of orthotics?

If your foot does not have the appropriate motion when striking the ground (overpronate or underpronate), joint pain is likely to follow.
Orthotics facilitate proper sequencing of foot mechanics to help the body transfer and absorb forces more efficiently.

1. Joint pain most commonly found in foot,
  ankle, knee, hip and/or low back
2. Re-occurring injuries on one side of the
  body
3. Leg length difference
4. Pigeon toed gait
