Flat feet are surprisingly common. Many people live their entire lives without a single symptom. But if you are experiencing foot pain, ankle aching, or tiredness in your legs after standing or walking, your flat feet might be part of the picture. Patients from Stillorgan and surrounding areas often ask whether their flat arches are something to worry about. The honest answer is: it depends. This post will explain what causes flat feet in adults, when symptoms mean you need help, how treatment works at Foot Focus Podiatry, and when it is time to see a podiatrist in Dublin.
What causes flat feet in adults?
Flat feet occur when the arch of the foot sits lower than typical or touches the ground completely when standing. Some people are born this way. Others develop flat feet over time. Understanding the cause matters because it shapes whether treatment is needed.
Inherited foot structure is the most common cause. If your parents had flat feet, there is a good chance you do too. This is not a defect. It is simply how your foot developed. Many people with inherited flat feet have no pain whatsoever.
Adult-acquired flat foot is different. This happens when the posterior tibial tendon, which supports the arch, weakens or becomes damaged over time. The arch gradually drops. This type often causes symptoms because the change places new stress on tissues that were not designed for it. Weight gain, ageing, and previous ankle injuries can all contribute.
Overload without adequate tissue capacity is the key concept here. Your foot can handle a flat arch if the muscles, tendons, and ligaments around it are strong enough. Problems start when load exceeds what your tissues can tolerate. This is why two people with identical arch heights can have completely different experiences. One has pain. The other does not.
What are the symptoms of flat feet?
Not everyone with flat feet has symptoms. When they do appear, they tend to follow a pattern.
The most common complaint is aching or tiredness along the inner ankle and arch after prolonged standing or walking. Some patients describe a feeling of the foot rolling inward. Pain in the heel, ball of the foot, or even the knee and lower back can develop as the body compensates for the changed foot position.
Swelling along the inside of the ankle is a warning sign, especially if it has developed gradually over months. Difficulty standing on tiptoes on one foot suggests the posterior tibial tendon may be struggling.
If you notice your arch has dropped noticeably compared to a few years ago, or if foot pain is stopping you from activities you enjoy, these are clear signals to get assessed rather than wait and hope.
How is flat feet treated at Foot Focus Podiatry?
Treatment for symptomatic flat feet follows our four-stage recovery model. The goal is not to create an arch that was never there. It is to build enough strength and tissue capacity so your foot can function without pain.
Stage 1 focuses on immediate pain relief. This might include supportive strapping, padding, or Class IV laser therapy to reduce discomfort and allow rehabilitation to begin.
Stage 2 introduces strength exercises. A progressive loading programme targets the muscles that support the arch and ankle. Every patient’s programme is different. The exercises are tailored to your current strength baseline and the demands of your daily life.
Stage 3 involves progressive loading. Activity levels increase gradually while pain trends are monitored. The aim is to steadily build what your foot can tolerate.
Stage 4 is return to full activity with a maintenance programme and the knowledge to manage your feet independently going forward.
For patients with chronic flat foot pain, gait analysis on our Gait and Motion Footscan pressure plate captures thousands of data points showing exactly how forces distribute across the foot. This data guides treatment decisions. If orthotics are clinically indicated after rehabilitation, Phits 3D printed orthotics are manufactured from your individual Footscan data. Orthotics are never prescribed in isolation. They support a structured strength and mobility programme.
Realistic timeframes vary. Mild cases may see significant improvement in six to eight weeks. Long-standing adult-acquired flat foot may take several months of consistent work. You can find out more about how we treat flat feet at our Dublin clinics on our flat feet page.
What patients in Stillorgan are asking about flat feet
Q: Do I need orthotics if I have flat feet?
A: Not necessarily. Many adults with flat feet never need orthotics. Treatment focuses on strengthening the foot first. Orthotics are only introduced if still clinically indicated after rehabilitation has begun. They are part of a programme, not a standalone fix.
Q: Can flat feet be corrected in adults?
A: The bony structure of an adult foot cannot be changed without surgery. However, symptoms can often be resolved by building strength and tissue capacity. The goal is a pain-free, functional foot rather than a different arch shape.
Q: Can I still run or exercise with flat feet?
A: Yes, in most cases. Flat feet do not automatically prevent activity. If running causes pain, a structured rehabilitation programme can address the underlying weakness. Many runners with flat feet compete without any issues once their foot and ankle strength matches the demands of their training.
Q: Do I need a GP referral to see a podiatrist for flat feet?
A: No referral is needed. You can book directly with a CORU-registered podiatrist at Foot Focus Podiatry. Assessment includes a detailed history, muscle and joint testing, and gait analysis where appropriate.
When should you see a podiatrist in Dublin?
Book an assessment if you notice pain along the inner ankle or arch that persists for more than two weeks. Swelling on the inside of the ankle that does not settle is another clear trigger. If you struggle to rise onto your tiptoes on one leg, or if your arch appears to have dropped compared to previous years, do not wait.
Foot pain that limits your walking, standing, or exercise is not something to push through. Early assessment prevents small problems becoming long-term limitations.
