A flexible flat foot is a foot structure that is only flat when your weight is put on your entire foot.  The arch is intact when the weight is taken off your heels. Unlike a structural flat foot, which is always flat, structurally stable and causes no chronic pain, a flexible flat foot is structurally unstable and can create severe chronic pain throughout your body.

If you have a flexible flat foot, when you stand or walk, the intermittent flattening of the longitudinal arch in your foot places a stretch on the muscles and ligaments which support the arch. This can result in foot pain.

Many Podiatrists are unaware of the fact that a common cause of the flexible flatfoot is an embryological abnormal foot structure – the PreClinical Clubfoot Deformity – and so, instead of treating the cause of the problem, they prescribe a therapy that only treats your symptoms.

When you visit a Podiatrist to address the problems resulting from your flexible flatfeet, they will often prescribe arch supports.  Arch supports will prevent the muscles and ligaments in your feet from being stretched and so you’ll have less foot pain.   But by their very nature, arch supports also weaken the muscles and ligaments in your feet because they support your arch.  This is analogous to a leg cast weakening your muscles while supporting your leg.


As the muscles and ligaments in your feet become weaker, when you don’t wear your arch supports, you’ll find that your unsupported arches become flatter. And as your arches become flatter, your foot pain increases. So you become addicted to wearing your arch supports in order to control your pain.

This is the vicious cycle:


  1. Arch supports are used to control foot pain – but at the same time, they make the muscles and ligaments in your feet weaker and weaker.
  2. As your muscles and ligaments become weaker, your arch drops more and more.
  3. As your arch drops more, you have more and more pain.
  4. As you have more pain, you will find yourself using the arch supports more and more to control your pain.


This is why, if you have a flexible flat foot, arch supports should usually be avoided.


  • Wearing Arch Supports For Flexible Flat Feet Creates Another Problem
  • When you wear your arch supports to control your foot pain, another issue is also created


Not only does your flexible flat foot become flatter due to the weakened muscles, but also, your foot twist (a twisting foot is another symptom of having a flexible flatfoot)  increases.

When your foot twist increases, your entire skeletal framework is affected. As a result, your posture becomes distorted. And with distorted posture comes pain.

The solution is to find an approach that gets rid of your foot pain without supporting your arches.  The proprioceptive insoles that I use as part of Rothbart Proprioceptive Therapy do not support your arches or any part of your feet or body.   Instead, these proprioceptive insoles work by sending a signal to your brain, which in turn adjusts your entire posture (including your feet) and realigns everything back into its’ proper position. This takes the tension off your joints and muscles so that they can heal.

So if you have a flexible flat foot and have found that you’re having more pain the longer you use your arch supports; instead of continuing in circles, why not try an approach that will give you permanent relief?

Reading this website will give you more information about the abnormal foot structures Professor/Dr. Rothbart discovered that cause many forms of chronic muscle and joint pain and help you determine whether an Initial Phone Consultation with him might be helpful.


Avoid Using Arch Supports If You Have A Flexible Flat Foot

Many people with flexible flatfeet are walking around on doctor prescribed arch supports.  This isn’t a good idea. But before I tell you why, let’s first look at what is a flexible flatfoot.
