Flat Feet in Adults: When to Seek Treatment

At Associates in Podiatry in Bedford, NH, we evaluate and treat flat feet when they start causing pain, instability, or limitations in daily activity. Flat feet occur when the arch collapses or never fully develops, which can shift how force moves through the foot and ankle. Many adults live comfortably with flat arches, but symptoms often appear when tissues fatigue, tendons weaken, or arthritis changes the joints over time.

Why Adults Develop Flat Feet

Some adults have flat feet because of genetics and lifelong arch structure. Others develop “adult-acquired” flatfoot when the arch gradually collapses. This often happens when tendons and supporting ligaments weaken or sustain injury.

Common contributors include aging, pregnancy, obesity, diabetes, rheumatoid arthritis, and prior foot or ankle injuries. These factors can increase strain on the structures that hold the arch up, especially the posterior tibial tendon, which supports the inside of the foot.

Signs That Flat Feet Need Professional Attention

Flat feet become more concerning when they cause ongoing symptoms or change how you walk. Seek podiatric evaluation when you notice:

• Persistent aching along the arch or inside of the ankle, especially after activity
• Swelling on the inner ankle or increasing tenderness along a tendon
• Foot or ankle fatigue that worsens with standing or walking
• Shoes that wear out unevenly or feel unstable
• Pain that spreads into the knees, hips, or lower back after time on your feet

These signs often indicate that the arch no longer supports load effectively, which can increase stress on joints and soft tissue.

How We Diagnose the Cause

We start with a simple gait and alignment assessment, looking at heel position, arch height, and how your foot functions during walking. We check areas of tenderness, tendon strength, and flexibility, and we evaluate whether the flatfoot remains flexible or has become rigid. When needed, we use imaging to look for arthritis, tendon changes, or structural issues that drive symptoms.

Treatment Options a Podiatrist May Recommend

Treatment depends on symptoms, activity level, and whether the condition continues to progress. Many adults improve with conservative care, including custom orthotics, supportive footwear, physical therapy, and lifestyle changes such as weight management to reduce pressure on the feet.

When conservative care does not control pain or when the foot becomes rigid or unstable, surgery may become appropriate to correct underlying structural problems. We discuss surgical options only after we clarify the diagnosis and confirm that non-surgical treatment does not meet your goals.
