Medial plantar neurapraxia (jogger's foot): report of 3 cases.

Entrapment of the medial plantar nerve in the longitudinal arch causes burning heel pain, aching in the arch, and deficient sensation in the sole of the foot behind the great toe. Long distance valgus running may cause such a disorder in a jogger and the condition usually responds to conservative measures which include a change in running posture of the foot, anti-inflammatory medications, and proper footwear. The name "jogger's foot" is selected for this clinical syndrome.
