If your arches sit flat on the floor and your feet ache after a long day, you’ve probably wondered whether flat feet can actually be fixed, or whether you’re stuck with them. It’s a fair question, and the internet is full of confident answers that don’t quite tell the truth.
Here’s the honest version. For most adults, you can’t rebuild a high arch without surgery, but you absolutely can fix the problem that matters: the pain, fatigue, and poor alignment flat feet cause. With the right support and a few simple habits, flat feet can feel stable, comfortable, and pain-free. Below is what genuinely helps, what to skip, and how to tell when it’s time to see a professional.
Quick Answer: How Do You Fix Flat Feet?
- Support the arch with a structured insole. This is the single highest-impact step.
- Strengthen your feet and calves with a few simple daily exercises.
- Wear stable, supportive shoes and retire the flat, floppy ones.
- Build up activity gradually instead of all at once.
- Be realistic. In adults, the goal is comfort and function, not reshaping the arch. In children, flexible flat feet often improve on their own with age.
What Are Flat Feet?
Flat feet, also called fallen arches or pes planus, means the arch on the inside of your foot is low or collapses flat when you stand. Some people are born with it; others develop it over time as the tendons and ligaments that hold the arch up gradually stretch and weaken.
Not everyone with flat feet has a problem. Many people never feel a thing. But when the arch collapses, it can throw off your alignment from the ground up, leading to arch and heel pain, tired feet, and even knee, hip, or lower-back aches. If you want the deeper background on how orthotics support a fallen arch, our guide to insoles for flat feet breaks it down.
What Causes Flat Feet?
- Genetics, since the foot shape often runs in families.
- Aging and wear, which gradually stretch the tendon that supports the arch.
- Pregnancy or weight gain, which adds load to the arch.
- An injury to the foot or ankle.
- Conditions like arthritis that affect the joints and soft tissue.
- Years of unsupportive footwear that let the arch collapse with every step.
Knowing your cause helps you focus. Either way, the foundation is the same: proper arch support.
Can You Actually Fix Flat Feet?
This is where honesty matters. As the American Academy of Orthopedic Surgeons explains, flexible flat feet in adults generally can’t be restored to a high arch without surgery, but the symptoms can usually be managed very well with simple, nonsurgical care. In other words, you fix the pain and the function, not necessarily the shape.
Children are a different story. Many kids have flexible flat feet that quietly develop an arch as they grow, so the focus there is comfort and monitoring rather than aggressive treatment. For adults, think of it like wearing glasses: you’re not changing your eyes, you’re giving them the support that lets you see clearly. The right arch support does the same for flat feet, every step of the day.
A Practical Plan To Support And Strengthen Flat Feet Exercises
| Approach | What to do | Why it helps |
| Arch support | Wear a structured insole in every shoe | Holds the arch up so it stops collapsing each step |
| Strengthening | Short-foot, towel scrunches, heel raises | Builds the muscles that support the arch |
| Footwear | Stable shoes with a firm heel and arch | Stops the arch from flattening as you walk |
| Activity | Increase mileage and standing gradually | Prevents overloading a weak arch |
1. Support the arch with the right insole
A structured orthotic insole holds the arch in a more natural position so the overstretched tendons and fascia stop doing all the work. For flat feet, you want firm, supportive structure rather than soft cushioning. The Redi-Thotics Control and Max lines are built for this, with a strong arch shell and a deep heel cup.
2. Strengthen your feet and calves
Short-foot exercise: without curling your toes, gently draw the ball of your foot toward your heel to lift the arch, holding for 5 seconds; repeat 10 times. Towel scrunches: scrunch a towel toward you with your toes, two sets of 20. Heel raises: rise slowly onto your toes, then lower; two sets of 15. Calf stretch: against a wall for 30 seconds, three times per leg.
3. Wear stable, supportive shoes
Choose footwear with a firm heel counter, good arch support, and a sole that doesn’t twist easily, then drop a supportive insole inside. For shoes that run shallow, full-length insoles with built-in arch support keep the structure consistent from heel to toe.
4. Build up activity gradually
If you’re starting a new workout or spending more time on your feet, ramp up slowly. Give the supporting tissues time to adapt.
How To Tell If You Have Flat Feet
Try the wet footprint test at home. Wet the bottom of your foot and step onto paper or a dry tile. If you see a full, filled-in imprint with little or no curve along the inside, you likely have flat feet. Other signs include arch or heel pain after standing, feet that tire quickly, shoes that wear down faster on the inner edge, and ankles that roll inward when you walk.
Best Shoes For Flat Feet (And What To Avoid)
The best shoes for flat feet are stable and structured. Look for motion-control or stability shoes, a firm midsole, and a supportive arch, and avoid the things that let the arch collapse: flat canvas sneakers, flimsy flip-flops, and going barefoot on hard floors for long stretches. The shoe and the insole work as a team.
When To See A Specialist
The Cleveland Clinic advises seeing a provider if flat feet cause ongoing pain, stiffness, or swelling, or if the symptoms don’t improve with supportive footwear. See someone promptly if one foot suddenly flattens, the arch becomes rigid and painful, or pain is sharp and worsening.
How To Keep Flat Feet Comfortable Long-Term
Keep wearing supportive insoles in your everyday shoes, do your foot and calf exercises a few times a week, replace insoles every 6 to 12 months, and keep choosing stable footwear.
The Bottom Line
You may not be able to rebuild a high arch as an adult, but you can absolutely fix the effects of flat feet on your comfort and stride.

Frequently Asked Questions
How do you fix flat feet?
For adults, the goal is fixing the symptoms, not the arch shape. Support the arch, strengthen your feet and calves, wear stable shoes, and increase activity gradually.
Can flat feet be corrected?
In children, flexible flat feet often develop an arch with age. In adults, the arch usually can’t be reshaped without surgery, but the pain and instability can be corrected effectively.
How do I know if I have flat feet?
Try the wet footprint test. A full imprint with a slight inner curve suggests flat feet, along with aching arches and ankles that roll inward.
What are the best shoes for flat feet?
Stability or motion-control shoes with a firm heel and supportive arch, plus a structured insole. Avoid flat, flimsy shoes.
Are flat feet bad?
Not always. Many people have no pain and need no treatment. They only need attention when they cause pain, fatigue, or knock-on aches.
