Definition
A condition where more of the foot surface is in contact with the ground than normal; it results from a decreased or absent longitudinal (toe to heel) arch.
Symptoms
People with flat feet have undeveloped longitudinal arch of foot when standing, and there is large contact area with ground in the footprint. When standing straight, their feet lean inward towards the center line of the body.
Biomechanical etiology
It is rare to see a person with a true flat foot. Normally, the person is only suffering from a functional flat foot. It is caused by overpronation that leads to break down and lengthen of arch of the foot. A functional flat foot is also called Pes Planus. It is common to see a person with a functional flat foot that causes sore, tired of the foot, fatigue and aches in the leg and body.
Treatment
A functional flat foot can be treated from orthotics like the Stabilizer Insoles that reduces calcaneal eversion and unlocks the mid-tarsal joints of the foot. Flexible and painless flat feet need not be corrected.
