Foot Mechanics

Pronation is presented as a normal and necessary foot action rather than an inherently pathological one. Calcaneal inversion locks the midfoot and forefoot, stiffening the foot and limiting pronation. Calcaneal eversion unlocks the midfoot and forefoot and permits pronation and natural arch flattening. The foot on the lunging side should pronate during the lateral lunge. Hip abduction can reinforce pronation, while hip adduction can reinforce supination or calcaneal inversion. Foot pronation contributes to the desired lower-extremity loading strategy. Foot mechanics are part of the progression’s coordinated lower-extremity strategy. Foot orientation may require addressing hip mobility and ventral cavity orientation rather than only local foot work.
