Patients with plantar fasciitis complain of sharp heel pain that radiates along the bottom of the inside of the foot. The pain is often worse when getting out of bed in the morning. This is easily correctable with the proper therapy and being fitted for custom foot orthotics may help prevent the recurrence of plantar fasciitis in the future.
Either pronation (collapsing arch) or supination (high arch) may be the cause. The flatfoot (hyperpronation) with associated forefoot abduction has a stretching effect on the plantar fascia, leading to repetitive tension overload. The high-arched foot (supinated) is relatively rigid. Forces usually absorbed through movement of the foot and ankle are transmitted to the plantar fascia and lower leg. In this way plantar fasciitis can be analogous to shin splints.
