Radiography

• X-rays are not helpful for this problem

Treatment

• Over the counter or custom orthotic with wedging of the orthotic to control foot pronation


• Use of supportive shoe with pronation control features including supportive midarch, torsional stability and rigid heel counters


• No barefoot walking during period of treatment


• Non-steroidal ant-inflammatory medications
