If your arches seem to be disappearing as you get older, you’re not imagining it. Flat feet in adults is a common and often progressive condition that can cause discomfort, fatigue, and even long-term mobility issues if left unaddressed.

Some adults are born with naturally low arches, but many develop flat feet over time due to aging, weight gain, injury, or overuse. One of the most common causes is posterior tibial tendon dysfunction (PTTD)—a weakening of the tendon that helps support the arch. Over time, this tendon can stretch or tear, leading to a gradual collapse of the arch and outward rolling of the ankle (also known as overpronation).

Symptoms often start with mild foot fatigue or arch pain but can progress to pain in the ankle, knees, hips, or even the lower back. You may notice your shoes wearing unevenly, or that standing for long periods becomes increasingly uncomfortable.

At Gauld Foot and Ankle, we evaluate flatfoot through physical exams, gait analysis, and imaging when necessary. Depending on severity, we may recommend custom orthotics to support the arch, physical therapy to strengthen surrounding muscles, or bracing to stabilize the foot and ankle. In more advanced cases, surgical correction may be considered—but most patients find relief through conservative measures.

If your feet are changing shape, don’t wait for symptoms to worsen. Early intervention can prevent a lifetime of discomfort. Schedule an appointment with Gauld Foot and Ankle to get your arches back in alignment.
