SMO

SMO is the acronym for Supra-Malleolar Orthosis. The SMO, as with other orthoses, gets its name for the part of the body for which it encompasses. This orthosis supports the leg just above the anklebones or malleoli. The SMO is considered the shortest of the Ankle Foot Orthoses or AFO’s.

• The SMO is prescribed for patients who have soft, flexible, flat feet. SMO’s are often
  worn by children. The medical term for a flat foot is a pronated foot or pes planus, pes plano-valgus, and hyper-pronated foot.
• The SMO is designed to maintain a vertical, or neutral heel while also supporting the
  three arches of the foot. This can help improve standing balance and walking.
