When we talk about our arches, we're most often referring to the medial longitudinal arch. Spanning the heel to ball of the foot, its main function is to distribute body weight and to absorb shock.
The medial arch has four common height postures:
Collapsed, low, normal or high - and each can affect the functionality of the foot,
and a pair of suitable insole can help relieve the foot pain and prevent the arches to be more serious.
Collapsed or Low Arch
Those who have collapsed or low arches are very likely to over-pronate. Collapsed medial arches can lead to poor foot function, instability and reduced shock absorption, resulting in pain and increasing susceptibility to injury.
A normal arch type is often good at absorbing shock, but there is still a likelihood of over-pronation, particularly if your arch types differ from right to left.
A foot with a high arch is often too rigid and inflexible, which increases the likelihood of supination during walking & running. This results in poor shock absorption, much of which can transmit up the kinetic chain into the leg, hip & back.
