Orthotic heel wedge insoles are typically prescribed to correct the calcaneal inversion and accompanying over pronation. The use of orthotics results in an apparent correction of the foot posture that always results in restoration of a healthy pressure footprint. However, we claim that orthotics has a drawback: they are passive and thus the resulting foot arch shape might not come as a result of the patients own muscles (as is the case in barefoot people). If such muscles are not exercised because the foot rests on top of a comfortable orthotic shape, they lose strength and consequently their beneficial functions of protective shock absorption, efficient gait [6] and other complex functions, as recently shown by [7] become impaired. In this work we present an over pronation and calcaneal inversion correction system that is based on active retraining of the foot muscle.
