The man, in upright position, is compared to a reversed pendulum balanced on a triangle supported by two symmetric parts: the feet.
The foot is the fixed point on the ground on which the whole body rests and for this reason it is the basis of the postural system or of the balance , in fact it allows the man to have an upright position and to move. It has the function of “ body absorber” as it compensates possible ground changes and it always acts independently from the postural imbalance.
Because of its continuous and constant stress it often has different pathologies of different origin that can be congenital or acquired because of a wrong posture.
Among the different foot pathologies we can have the hollow foot which consists of a malfunction of the sole of the foot and that we could define the opposite of the flat foot: in the flat foot the sole rests completely on the ground while in the hollow foot the concave area is so protruding to damage the correct support of the heel as the supporting area is limited to the front foot and the heel.
For a correct treatment of the foot and of its load it is not enough to look at the foot but it is necessary an accurate diagnosis , for example a postural exam that highlights a series of pathologies of different kind.
