Fig. (1) A 19 year-old male patient presented with recurrent ankle sprains on the right side. Elevated medial longitudinal arch is indicative of a cavus foot (A)M. Depressed 1^st metatarsal head can accompany plantar callus (B). Observation of the medial border of the heel from the front, a positive peek-a-boo heel sign, is suggestive of heel varus (C).
