What is flat foot?

👣THE flat foot is a foot of which the arch between the arch and the heel is almost or completely non-existent, giving this “flat” profile effect. The diagnosis of flat foot is made using a podoscope by a podiatrist.

You can have flat feet from childhood or adolescence if your foot is not forming properly during growth, or your feet may become flat as adults, due to a sagging of your arch or an injury such as a ruptured tendon. Flat feet can also appear in adulthood as a result of osteoarthritis.

👉The problem with flat foot is that it means your foot is entirely in contact with the ground when you are standing. Your natural posture is therefore not good, and you may have a tendency to collapse your foot inward to be more comfortable. Issue ? Your knees and back risk suffering from this poor posture.

This is where comes in flat foot orthopedic insoles.

VShow to know if you have a flat foot problem ?

The flat foot problem can be detected in several ways.

Firstly, if you suffer from recurring pain under your heel, like a thorny feeling, and pain under the arch of your foot, then this may be a sign of flat feet.

What shoes to wear when you have flat feet?

For your flat foot orthopedic insole to have a positive effect on your posture, it is recommended to wear it with the appropriate shoes. Choose une pair of shoes that offers good arch support, leave alone room for toes , has a small heel (but not more than 6cm) to allow you better shock absorption, and a flexible sole.


✅ Comfortable sneakers or dress shoes are the basic shoes to adopt when you suffer from flat feet. You must choose them in leather and not in fabric so that the support is sufficient and the shoe absorbs shock.
Shoes should be wide enough not to compress your foot, but secure enough to ensure it does not move when you walk.

High ankle boots

✅ Wearing high ankle boots which provide better ankle support is also recommended in the case of flat feet. Thanks to laces or a zipper, you can tighten your foot inside to ensure good support.

Be careful to choose them without a high heel though.


✅ Boots with a leather upper will not only provide good support for your ankle, but also ensure that your foot remains in place. Choose them in leather and without a high heel for greater efficiency.

What shoes to avoid when you have flat feet?

Flat sandals

Summer can be a real period of suffering for people who have flat feet. Indeed, with the heat, we tend to turn to sandals to be comfortable and not to be too hot. Unfortunately, it is difficult to slip orthopedic insoles into them to be comfortable!

🔴 Most sandals also have a flat leather upper, too thin to absorb shock and allow the foot to regain a natural curvature.

Also, sandals are not recommended for people with flat feet. The only models that might be suitable would be those with a small heel or a thick sole to protect the arch.

Flip flops

🔴 With their somewhat thick and comfortable plastic sole, you might think that flip-flops are recommended for flat feet. Nay! Flip-flops should be banned for walking all day if you suffer from flat feet. Only wear them to the pool or the beach, but no more.

High heels

🔴 Whether you wear sandals, pumps or high-heeled ankle boots, they are all not recommended if you suffer from flat feet. Because of their height and shape, they unbalance your gait and do not provide you with well-distributed support. Over the long term, wearing heels can worsen flat foot problems by forcing the sole of the foot into an arched position. 


🔴 You might think that because they fall into the category of sneakers, Converses are authorized when you have flat feet. On the contrary ! The Converses have a very thin outsole, and no reinforcement allowing good absorption of things. The fabric exterior does not support the foot well enough despite the laces.

Results: the feet are in almost direct contact with the ground because of the thin sole, and no curvature can remedy the flat foot problem. Even if you insert orthopedic insoles for flat feet, your Converses risk giving you sore feet at the end of the day...

Ballet flats

🔴 The thinnest and flattest models provide no shock absorption. Even with insoles, you will have foot pain, and the therapeutic effects of insoles will be diminished with the wrong pair of shoes. Instead, opt for moccasins or sandals with low heels to add a little curvature to your foot and protect your heel.
