Flatfoot

When the arch collapses and your feet tire easily

Flatfoot is when the arch structure (the curve on the bottom of the foot) collapses and becomes flat.
The arch works as a spring that absorbs shock during walking, running, and standing.
It can be present from birth (congenital) or develop later due to aging, weight gain, or muscle weakness (acquired).
Not every flat foot needs treatment: if there is no pain or other symptom, no treatment is required. Many people have no symptoms at all, but if pain is ignored for a long time it can be associated with plantar fasciitis or bunions, and the strain can spread to the knees and lower back.

1
Naturally low arch from birth

Bone alignment or loose ligaments may prevent the arch from forming properly

2
Muscles and tendons weaken over time

Aging, weight gain, and long hours of standing wear out the tissues supporting the arch

3
The arch collapses and shock absorption decreases

Foot pain, tiredness, and an uneven walking pattern develop

4
Strain spreads to the knees and lower back

Foot misalignment can travel up and cause knee pain or back pain

⚖️ Excess weight 🧍 Standing for long hours 👟 Ill-fitting shoes 👴 Aging
🦶
Pain in the arch of the foot
🚶
Feet tire easily after long walks
🌅
Pain with the first step in the morning (may indicate plantar fasciitis)
🦵
Knee or back pain has started
👟
The inside of your shoes wears out faster, or your feet feel wider
👟
Insole Therapy
Spread the load on the foot to ease pain. Insoles do not correct the deformity itself
🏋️
Foot Muscle Training
Towel curls and calf raises to strengthen the muscles supporting the arch
⚖️
Weight Management
Losing weight reduces the load on your feet
👟
Proper Footwear
Choose cushioned shoes that fit your feet well
🧘
Stretching
Calf and Achilles tendon stretches to keep the feet flexible
🔬
Surgery (Severe Cases)
Tendon transfer or osteotomy may be considered for severe deformity. We do not perform surgery here, so we refer you to a partner hospital
🌿

Insoles and training can improve symptoms

Supporting the arch with insoles while continuing foot muscle training can reduce pain and fatigue. If pain is ignored for a long time, flatfoot can be associated with plantar fasciitis, bunions, shin splints, and other conditions.

Conditions related to flatfoot
Untreated flatfoot can lead to plantar fasciitis (heel pain), bunions (big toe deformity), shin splints (shin pain), and posterior tibial tendon dysfunction (PTTD). If pain or tiredness in your feet persists, please see an orthopedic clinic early.

💡 Habits to Protect Your Arch

  • Do towel curls (scrunch a towel with your toes) daily
  • Choose cushioned shoes and also spend some time barefoot
  • Maintain a healthy weight
  • If foot pain persists, we can check the cause with X-ray or ultrasound
