Pes Planus - Flat Feet


Pes Planus (flat feet, fallen arch) is a common condition where more of the foot surface is in contact with the ground than normal, resulting in a decreased or collapsed arch. Patients often state that they have a "fallen arch" and can typically have pain on the inside of the ankle upon palpation, cramping of the lower extremeties, knee pain and hip pain. A Pes Planus or excessively pronated foot (fallen arch) often leads to Bunion formation due to the excessive workload on the big toe. A Pes Planus foot type also can lead to Posterior Tibial Tendon Dysfuction. If not treated the Posterior Tibial Tendon can lose function and the arch of the foot totally collapses, thus generally requiring surgical intervention (ankle fusion).


Pes Planus can be caused by numerous conditions, includiong an inherited Bio-Mechanical foot etiology, excessive weight, poor footwear/arch support and excessive pronation. A common and usually painless condition, flatfeet may occur when the arches don't develop during childhood. In other cases, flatfeet may develop after an injury or from the simple wear and tear stresses of age. Flatfeet can sometimes contribute to problems in your ankles and knees because the condition can alter optimal alignment of your legs.

At Corey's Bootery we treat a Pes Planus foot type agressively to protect the Posterior Tibial Tendon as well as slowing the progression of any Bunion formation, while preserving function and comfort of the foot. We recommend a Brooks motion control shoe, custom orthotics with proper arch suppport, medial heel wedges and a proper fit shoe with a firm extended medial counter. Often times in moderate to severe cases of a Pes Planus foot type, we will make custom UCBL orthotics for maximum support.
