Normal arch: The normal arch allows weight and pressure to be evenly distributed across the foot to minimize faulty biomechanics that may affect not only the feet, but also the ankles, knees, and back. This imbalance can then translate upward affecting other parts of the body such as our knees and back. This imbalance may increase the progression of underlying foot deformities such as bunions and hammertoes and lead to painful conditions associated with excessive pronation such as arch/ heel pain, shin splints/ posterior tibial tendonitis, and achilles tendonitis. Our feet naturally pronate during the gait cycle, however when we have flat feet we pronate for a longer period of time which then alters the biomechanics and distribution of pressure and weight across the foot. Prolonged periods of time allows our foot to collapse affecting our gait and posture, which can lead to a tremendous amount of stress not only to the foot but to the rest of the body. Severely rigid flat feet can also lead to posterior tibial tendonitis due to the constant strain of the tendon. Chronic rigid flat foot and functional limb length discrepancies can occur if left untreated. The posterior tibial tendon helps to hold the arch in proper position and when this tendon in damaged, a painful lowering or collapse of the arch develops. This occurs when the posterior tibial tendon gets inflamed or injured. Posterior Tibial Tendonitis or Adult Acquired Flatfoot is another term used to describe the Painful progressive flatfoot. When flat feet become symptomatic, a thorough foot evaluation is recommended. Many people who over-pronate do not experience any pain or discomfort. The more a person pronates, the flatter the arch will be. Your foot is not absorbing much shock when you run.įlat feet: The amount of pronation correlates with arch height. High arch: If your arch has little to no arch than you have a high arch. A normal arch supports your bodyweight and pronates normal. Normal arch: If you see about half of your arch region then you have the most common foot type. Step onto a piece of paper and look down.įlat (Low) arch: If you see the arch mostly filled in then your foot is most likely collapsing inward when you run. Insert your foot into the pan to wet the soles of your feet. The easiest way to determine your arch type is to do a "home water test". When weight bearing there is significantly more space in between the floor and the arch. High arch: High arches are a genetically inherited condition where your arch is much higher or raised than normal. If you can place the paper in between your foot and the floor you have a normal arch. A good test is to try and slip a piece of paper below the arch. Normal arch: The normal arch has the middle part of the arch slightly raised from the ground when weight bearing. The amount of pronation correlates with arch height. WHAT DIFFERENT TYPES OF FOOT ARCHES ARE THERE?įlat feet: Pronation is a term used to describe the inward leaning motion of the foot and ankle bones towards the arch. It is important to know your arch type in order to identify and buy shoes that will best support your bodyweight to relieve foot pain and prevent injuries such as plantar fasciitis.
