When you look at the inside of your foot, do you notice that the arch sits flat on the floor? As you age, or if you work a job that requires standing for long periods, you may experience foot fatigue, knee pain, or lower back discomfort. Flat feet (pes planus) is a biomechanical issue found in approximately 20-25% of adults in Turkey that can be effectively managed with the right insoles. In this guide, I detail what you should look for when choosing insoles for flat feet, which features truly make a difference, and what modern solutions like FootBalance QuickFit have to offer.
What Are Flat Feet, and Why Are Insoles Essential?
Normally, there is an arch on the inside of the foot. This arch balances the body's weight while walking, absorbs shock, and rests the foot. In flat feet, this arch has collapsed or never formed. As a result:
- The foot rolls inward while walking (over-pronation)
- Body weight is concentrated on the inner edge of the foot
- Knee and hip alignment is disrupted, leading to back pain
- Feet tire quickly during long walks
- Secondary issues like plantar fasciitis or hallux valgus may develop
- The right insole provides external support to this arch and accomplishes three things: it puts the foot in the correct position, reduces strain, and prevents upper-joint issues.
- At FootBalance Turkey, what we see in our 50+ centers is this: the vast majority of users with flat feet come in after years of suffering from knee or back pain, only realizing later that the root cause is foot biomechanics. This difference becomes clear during the 30-second molding phase in the store.
6 Critical Features to Look for in Flat Foot Insoles
1. Arch Support at the Right Height
For a user with flat feet, arch support is critical, but if done incorrectly, it can cause harm. An arch that is too high puts pressure on the foot and causes pain; an arch that is too low provides no benefit.
What to look for: Mid-level arch height — a slightly elevated support close to the structure of your foot. Ideally, insoles that can be customized to the individual.
2. Rigid Heel Cup and Stability
With flat feet, the heel tilts slightly inward (everted). The correct heel cup prevents this tilt and keeps the foot properly aligned.
What to look for: A rigid plastic or thermoplastic heel cup, a deep structure, and a snug fit around the foot.
3. Shock-Absorbing Structure
In a flat-footed person, impact is transmitted through the entire body without being absorbed. Therefore, shock-absorbing padding in the heel and forefoot area is critically important. What to look for: EVA or gel padding under the heel and a flexible foam layer under the forefoot.
4. Orthopedic Molding
Standard arch-supported insoles are manufactured for an average foot. The degree of flat feet varies from person to person. Mild flat feet and severe pes planus require different levels of support.
Ideal solution: Insoles that provide a custom fit, such as QuickFit technology that can be molded at home in a microwave.
5. Correct Size and Width
The insole must fit the internal volume of your shoe. An insole that is too thick will make the shoe feel tight, while an insole that is too short will not sit properly against the heel.
What to check: Use in shoes with removable insoles, and check for length and width compatibility.
6. Brand with a Clinical Background
Flat feet are an orthopedic condition. Choose brands backed by clinical research and recommended by podiatrists or orthopedic doctors. FootBalance, which is of Finnish origin, is known for its QuickFit series that has been in global clinical use since 2006.
FootBalance QuickFit: Which Model for Flat Feet?

What Are the Symptoms of Flat Feet?
Typical signs that you might have flat feet:
- When you step on the floor with a wet foot, the print covers the entire sole (normally, there shouldn't be an arch print in the middle)
- Pain and fatigue on the inner side of the foot during long walks
- Knee or back pain (side effect)
- The inner side of your shoe sole wears out more than the outer side
- Feeling relief when you try on shoes specifically made for flat feet
- If you have 2-3 of these symptoms, you may have a flat foot problem. Consult an orthopedic doctor or podiatrist for a definitive diagnosis.
Sports and Flat Feet: How Do Insoles Help?
Users with flat feet place extra load on the knees and back during high-impact sports like running, soccer, or tennis. The right sports insole:
- Controls pronation and prevents excessive loading on the knees
- Absorbs heel impact and protects the back-lumbar chain
- Prevents performance decline and reduces the risk of injury
- FootBalance QuickFit offers models for every branch of sport.

Frequently Asked Questions
Do flat feet get corrected with insoles?
In adults, the structure of a flat foot does not fully recover, but with the right insoles, symptoms (pain, fatigue, pressure) are significantly reduced. In children, structural improvement is possible with insoles + physical therapy at an early age.
Is surgery necessary for flat feet?
Most cases of flat feet do not require surgery. The right insoles + appropriate shoes + strengthening exercises are usually sufficient. Surgery is the last resort only for severely painful cases.
Are QuickFit insoles enough for flat feet?
QuickFit Balance provides sufficient support for mild-to-moderate flat feet, while the Control model is sufficient for advanced cases. In very severe cases, a custom-made mold may be required based on your doctor's recommendation.
Can the insoles be worn in every shoe?
QuickFit can be used in all shoes with removable insoles — running shoes, casual sneakers, office shoes, and most boots are compatible.
Are there insoles for children with flat feet?
Yes, FootBalance has children's models in smaller sizes. Early intervention in children is very important for structural improvement.
Conclusion: The Right Insole for Flat Feet Saves Lives
