A lowering or collapsing of the longitudinal arch in the foot.
A functional flat foot is quite common and can result in symptoms ranging from sore or tired feet to general leg fatigue and body aches and pain. There is a positive correlation between flat feet and symptoms involving foot pain, leg pain, knee pain, hip pain and lower back pain.
Excessive pronation (feet ‘ rolling’ inwards) causes the arch to collapse and elongate, giving the foot an appearance of being ‘flat’.
Controlling excessive pronation, with orthotics (custom-made shoe inserts) prevents the feet ‘rolling’ inwards during walking. This prevents ‘unlocking’ of the 33 joints in the feet, which is often the cause of painful symptoms in the pes planus foot type.
Your PODIATRIST can also advise you on stretches that can be of benefit.
