Plantar fascitis is a common foot problem caused by excessive pronation, with excessive pronation-what other conditions develop?

No. Tarsal tunnel syndrome which is a compression of the posterior tibial nerve that with a decreased longitudinal arch can compress and excessively load the PTT creating pain, tingling and difficulty walking.

Excessive pronation can also potentially create heel spurs. Because of the attachment of the plantar fascia that originates from the calcaneous and inserts on all 5 metarsal heads, a person who has plantar fasciitis will walk differently by avoiding potentially loading the midfoot in full midstance and present with a stronger heel strike which is excessive loading of the calcaneous.

Somethings to think about biomechanically?
