Flat Feet

Flat Feet Treatment in Portsmouth & Nashua, NH

Flat feet can lead to pain, fatigue, and instability throughout your body—not just in your feet.

What Are Flat Feet?

Flat feet occur when the arch of the foot is low or collapsed, causing the entire sole to make contact with the ground when standing.

Some people are born with flat feet, while others develop them over time due to injury, tendon issues, or gradual changes in the body.

Symptoms of Flat Feet

People with flat feet often experience:

Pain in the arch, heel, or ankle
Foot fatigue after standing or walking
Swelling along the inside of the foot
Instability or poor balance
Knee, hip, or lower back discomfort

What Causes Flat Feet?

Genetics or naturally low arches
Tendon dysfunction or weakness
Injury to the foot or ankle
Aging and wear over time
Weight changes or pregnancy

Why Support Matters for Flat Feet

Your feet are your body’s foundation. When they lack proper support, it can affect alignment from the ground up.

Flat feet can lead to:

Overpronation (foot rolling inward)
Increased stress on joints
Strain in the knees, hips, and back

Proper support helps restore alignment and reduce unnecessary stress.

Treatment Options for Flat Feet

Flat feet can often be managed with conservative care focused on improving support, alignment, and function. Your treatment plan will depend on your symptoms, activity level, and the underlying cause.

Custom Orthotics & Arch Support

Designed for your feet to improve alignment, support the arch, and reduce strain on joints and soft tissues. This is often the most effective long-term solution.

Supportive Care & Footwear

In some cases, supportive inserts, proper footwear, bracing, or targeted exercises can help improve stability and reduce discomfort during daily activities.

Advanced & Surgical Options

For more persistent or severe cases, treatments such as MLS Laser Therapy, Shockwave Therapy, or surgical correction may be recommended.

When to See a Podiatrist

Flat feet don’t always cause problems—but when symptoms begin to affect your comfort, stability, or daily activity, it’s a good time to get evaluated. Early treatment can help prevent worsening pain and long-term alignment issues.

You should consider an evaluation if:

You have ongoing foot or ankle pain
Your feet feel tired or unstable regularly
You notice changes in how you walk
Pain is affecting your daily activities or exercise
Symptoms are getting worse over time

Early evaluation can often lead to better outcomes and may help slow progression. Give us a call or message us to schedule an appointment at our office in Portsmouth or Nashua.

The folks at Northeast Foot and Ankle are great! The staff were very kind and knowledgeable. The new patient process was very easy to do and they offered the ability to do it in advance on the portal. My appointment was on time and I was out in under 45 minutes.

Very happy I chose Northeast Foot and Ankle! Dr. Sartori and the entire staff are very attentive and knowledgeable. I had a bunion removed and from my initial appointment, through the surgery, and to the last follow up I always had a great experience. I highly recommend this group!

Jennifer

Total experience rates a 10. Dr. Baczewski was the epitome of what a medical professional should be. She offered a choice of options to alleviate my foot pain. Once I opted for surgery, the process went smoothly both in the surgery center and the office for post operative laser and follow up. The entire staff was welcoming, courteous, and highly trained. The facility was easy to access with ample parking. The online reminders for appointments was also a plus.
I would highly recommend Northeast Foot and Ankle.

Leslie

Both doctors are excellent practitioners who explain things upfront and do not try to upsell/push unnecessary services. I recommend laser treatments if you have persistent warts.
They also saved my baby sister’s life when the ER doctors wanted to send her home while she had a huge infection on her heel—one call from Sartori and she was admitted for three days and got the right treatment. She turned 21 this summer ☺️ these people care and do a great job!!
