Flat feet is a condition that is worth demystifying as there are many myths around it. This condition can be caused by various anatomical or functional issues but it doesn’t always need orthotics or support. Understanding the causes behind flat feet is more important than knowing that you have flat feet.
- A low calcaneal angle is a genetic factor where the bony structure of the foot is naturally at a low angle causing a flat foot. This condition doesn’t usually cause symptoms and it rarely necessitate any intervention.
- One common cause of flat feet is having a Short Achilles Tendon: When the Achilles tendon is too short, it pulls the heel up and increases pressure on the midfoot, resulting in the arch flattening. Daily stretching of the Achilles tendon is a good practice and avoiding flat footwear is another good habit to address this imbalance.
- Another cause of having flat feet is posterior tibialis dysfunction. The posterior tibialis muscle and tendon play a crucial role in supporting the arch. When this tendon weakens or tears, the foot may lose its arch, leading to a flat foot. This is often observed in middle aged women and can result from overuse, injury, or chronic stress on the tendon. It most often happens in one foot and it is extremely important to detect this condition early on and treat is as soon as possible to avoid surgery.
- Hyperlaxity, or excessive flexibility in the ligaments, is a condition that makes it challenging for the body to support the foot’s arch effectively. People with hyperlaxity often have joints that move beyond typical ranges, making them more prone to flat feet, keen and lower back pain. This cause of flat feet responds very well to supportive shoes combined with orthotics.
- An accessory navicular, an extra bone on the inner side of the foot, can also lead to flat feet. This additional bone disrupts the normal function of the posterior tibialis tendon, reducing its ability to support the arch. People with an accessory navicular may experience pain and flat-footedness, especially with physical activity. This condition is easily detected in weight bearing x-rays.
