Flat feet are one of the most common concerns patients bring to our clinics in Finglas and Mount Merrion. Many people worry that their low arches are causing their foot pain or will lead to problems down the line. The truth is more reassuring than you might expect. Plenty of adults have flat feet and never experience a single symptom. Others develop pain that gets blamed on flat feet when the real issue lies elsewhere. This post will explain what actually causes flat feet, when they need attention, the symptoms to watch for, and how we approach treatment at Foot Focus Podiatry.
What causes flat feet in adults?
Flat feet happen 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 flatter arches over time. Understanding the cause matters because it shapes whether treatment is needed.
Inherited foot structure is the most common reason. If your parents had flat feet, you likely have them too. This is simply how your foot developed and often causes no issues at all.
Acquired flat foot develops later in life. The posterior tibial tendon runs along the inside of the ankle and supports the arch. When this tendon weakens or becomes damaged, the arch can gradually collapse. This is sometimes called adult-acquired flatfoot deformity. It tends to affect one foot more than the other and can cause significant pain if left unaddressed.
Muscle weakness and reduced mobility also play a role. When the muscles that support the arch lack strength, the foot cannot hold its shape under load. This is where the load versus capacity principle becomes important. Pain happens when the demand placed on the foot exceeds what the tissues can handle. A flat foot with strong, well-conditioned muscles may never cause trouble. A flat foot with weak supporting structures might struggle under everyday walking.
What are the symptoms of flat feet that need attention?
Most flat feet cause no symptoms. The arch shape itself is not a problem. Symptoms only matter when they limit your life.
Pain along the inside of the ankle or arch is the most common complaint. This often worsens with activity and improves with rest. Some people notice their feet tire quickly during walking or standing. Others feel aching in the lower legs or knees after time on their feet.
Swelling along the inner ankle can indicate posterior tibial tendon involvement. A foot that has recently become flatter, especially on one side, deserves prompt attention.
If you notice your arch collapsing over weeks or months, if one foot looks noticeably different from the other, or if foot pain is affecting your ability to work or exercise, it is time to book an assessment. Waiting often allows the problem to progress when earlier intervention could have made a real difference.
How are flat feet treated at Foot Focus Podiatry?
Treatment depends entirely on whether the flat feet are causing symptoms and what is driving those symptoms. At Foot Focus, every patient receives a thorough assessment. This includes a detailed history review, muscle and joint testing, and baseline strength measurements. For patients with ongoing pain or functional concerns, we follow this with gait analysis using our Gait and Motion Footscan pressure plate. The Footscan captures thousands of data points showing exactly how forces distribute across your foot with every step.
Treatment follows our four-stage recovery model. Stage one focuses on immediate pain relief through strapping, padding, or Class IV laser therapy to calm symptoms. Stage two introduces strength exercises designed to build the capacity of the muscles supporting your arch. Stage three involves progressive loading, gradually increasing activity while monitoring how your foot responds. Stage four means returning to your chosen activities with a maintenance programme and the knowledge to stay pain-free.
Orthotics are never our first answer. We build foot strength through rehabilitation and only introduce orthotics if they remain clinically indicated after the foot has been strengthened. When orthotics are appropriate, we use Phits 3D printed orthotics, custom-manufactured from your individual Footscan pressure data. These are part of a structured strength and mobility programme, not a permanent crutch.
Most patients see meaningful improvement within eight to twelve weeks when they engage with the rehabilitation process. You can find out more about how we assess and 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 people with flat feet never need orthotics. Orthotics are only recommended when flat feet cause symptoms that do not respond to strengthening alone. A proper assessment determines whether they would help your specific situation.
Q: Can flat feet be corrected in adults?
A: The bone structure of a flat foot cannot be changed without surgery, which is rarely needed. However, the strength and function of a flat foot can be dramatically improved. Stronger muscles support the arch better and reduce or eliminate symptoms.
Q: Will flat feet get worse as I age?
A: Flat feet may become more symptomatic with age if the supporting muscles and tendons weaken. Maintaining foot strength through regular exercise helps prevent this. If you notice your arch dropping or new pain developing, an assessment can catch problems early.
Q: Can I still run with flat feet?
A: Yes. Many runners have flat feet and train without any issues. Problems arise when load exceeds tissue capacity. A podiatrist can assess your running gait and help you build the foot strength needed to run comfortably.
When should you see a podiatrist in Dublin?
Book an assessment if you notice pain along the inside of your ankle or arch that does not settle within a few days. Swelling on the inner ankle, especially if it appeared recently, needs prompt evaluation. A foot that has visibly flattened over recent months should be checked. If foot fatigue or aching is stopping you from walking, exercising, or standing comfortably at work, treatment can help.
Patients based in Stillorgan or the surrounding Dublin 14 area can book online or call our Mount Merrion clinic directly. Our Finglas clinic serves patients across Dublin 11 and North Dublin.
