Many people are born with flat feet, in fact there is almost a 1 in 3 chance that a person will be born with at least moderately flat feet. There is also a smaller number of people who have a condition called acquired flatfoot. Acquired flatfoot or “fallen arches” results from failure of the posterior tibial tendon. This tendon and the associated muscle are responsible for maintaining the arch of the foot as the heel comes off the ground. When the tendon fails to function properly the arch can become progressively flatter and the foot turns outward.
Having flat feet is generally not too troublesome but it can lead to many serious conditions such as posterior tibialis tendonitis (acquired flatfoot deformity), tarsal tunnel syndrome, and plantar fasciitis. The worst part about this is that it can develop all three at the same time. Instead of just correcting for flat feet, three separate conditions may have to be treated which causes increased pain, discomfort, and time away from the things you love. Not only does it cause those issues, but it can also lead to ankle arthritis, metatarsalgia, or even a second metatarsal stress fracture.
