Customised foot orthoses effective for pain due to pes cavus

Clinical question: 
Do customised foot orthoses reduce foot pain associated with pes cavus?
Bottom line: 
Compared to sham orthoses, custom-made foot orthoses reduced and redistributed plantar foot pressure and subsequently decreased foot pain by approximately 75%. There was also a significant improvement in foot function and increased physical functioning. There was no difference in reported adverse events between the two groups. Foot pain and foot function was measured using the validated Foot Health Status Questionnaire and physical function was assessed using the Medical Outcomes Short Form.
Caveat: 
Only one trial of custom-made foot orthoses met the criteria for inclusion in this review of interventions for pes cavus. The follow-up period of the trial was only 3 months.
Context: 
Pes cavus has a prevalence of approximately 10%, and its cause is primarily neuromuscular (eg. Charcot-Marie-Tooth disease) or idiopathic in nature. It has been estimated that 60% of people with pes cavus will experience chronic foot pain at some time in their life.
