Pes planus, or flat feet, occurs when the arch on the underside of your foot collapses. This causes the foot to flatten out. When you have flat feet, the entire sole of your foot touches the ground when you walk. This condition is generally painless, but it can lead to some problems with your feet over time, primarily with the alignment of the other structures in the foot. Here are five common issues that can arise from flat feet.
Heel Strain
Strain to a vital ligament in the heel is one of the more likely problems that can occur from walking with fallen arches. This ligament, plantar fascia, provides support to the bones that make up the back of the foot. As you step, the ligament stretches. Flat feet cause an unnatural alignment of the foot. This means when you walk, the plantar fascia strains to compensate. Eventually, that strain causes damage to this ligament.
Bunions
A bunion is a bony structure that forms at the base of the big toe. Flat feet can cause the bones in the toe, and specifically the first metatarsal bone, to shift. The shifting will be very gradual. It may take years for the alignment to change in the toe. As the toe pushes outward, you will start to see the head of the metatarsal bone pressing against the skin. This is the beginning stages of bunion formation.
Hammer Toes
Hammer toes form the same way bunions do. The fallen arches cause misalignment of the toes. When the bones push upward, the middle joint can move out of alignment. The friction from your shoes rubbing against that joint causes corns to form and eventually a bony structure that becomes a hammer toe.
Tendon Inflammation
Tendons are thick cords that attach muscles to the bones. When this fibrous tissue becomes irritated, it can swell. This condition is tendonitis. With tendonitis, you will feel pain when you try to put weight on your foot. If you have flat feet, tendonitis can become a chronic problem. Repeated incidents of tendon inflammation may cause permanent damage to the muscles and connective tissue of the foot.
Ankle Strain
Ankle problems will be similar to the tendon issues in the foot. The misalignment will cause strain and pinching on the connective tissue of the ankles. This would include muscle, tendons and ligaments. Ankle problems can be secondary to other foot problems. For example, if you have heel strain, you may walk differently and put additional pressure of the ankles.
It is vital to remember that problems with flat feet will develop over time. The key to avoiding foot problems is supportive arches in your shoes even if you don’t currently feel any pain resulting from your flat feet.
