A Supramalleolar Orthosis (SMO) is a custom-made inner shoe orthosis supporting the foot above the ankle joint.

SMO's provide some medial and lateral support while allowing full plantarflexion and dorsiflexion.



  • Excessive pronation and/or supination.
  • Delayed development with very low tone pronation and sensory issues.
  • High level of specific foot correction but have adequate ankle control for functional level.
  • Patients who engage in frequent floor activities requiring free ankle movement.
