is the biomechanical shock absorbing motion of the ankle, foot and
lower leg. Pronation refers specifically to the natural inward flexing
motion of the lower leg and ankle. Running, walking and standing
cause the ankle joint to pronate which helps the body to absorb
shock and control balance.
a flexible ankle joint may pronate more than desired. This common
condition is referred to as over-pronation. Over-pronation
puts extreme strain on the various connective tissues of the foot,
ankle and knee. If left uncorrected, over-pronation can lead to
flat feet (falling arches), ankle & foot injuries, foot deformities
(such as bunions and hammer toes) and heel pain.
