Orthotics for Kids with Knock Knees – Let’s Improve your Kids’ Posture!

Improve Your Child's Posture

Have you been looking for a pair of orthotics for your child with knock knees? Did you know that orthotics can reduce or fully eliminate foot and leg pain, improve your child’s posture by helping your child walk and run straighter?

If your child has been diagnosed with knock knees and you have been looking for the perfect pair of shoes and orthotics, I will help you find them.

I have been working for a specialized children’s shoe store for over 10 years now, and I know everything that relates to children’s shoes and the way they fit. This is a specialized shoe store that focuses on children with foot and leg problems, but we provide regular shoe fittings as well. We carry some of the most supportive children’s shoes and orthotics, and I am familiar with which shoe brands and which shoe styles are better than others.

Let me first start by clarifying what this condition is:  Knock knees which is scientifically known as Genu Valcum is a condition where the two knees touch each other while standing straight. It’ important to understand that knock knees are opposite of bow legs, since in the case of bow legs, the knees are far away from each other.

If you are unsure whether your child has knock knees or not, I recommend that you make your child stand up straight (make sure he/she is looking straight ahead) and check if the knees are touching each other. Take a look at the image below that will provide you with an example of a child that has knock knees:

The condition usually becomes apparent when a child is 2 to 3 years old, and it may increase in severity until about age 4.

While for younger kids knock knees are just a normal part of growing up, I strongly recommend parents to not leave this condition untreated, since it can lead to foot, leg, and back pain.

The issue is that there are only a few orthotic styles that will be effective in helping straighten your kids’ feet and legs. The good news is that I know exactly which orthotics are most effective in treating knock knees since I have fitted them before.

Something so simple such as providing your child with the correct pair of shoes and orthotics will have a huge impact in the way your child walks and runs.

The orthotic I will recommend will help your child walk and run straighter, but if your child has a severe case of knock knees then you must try a different orthotic such as an ankle brace orthotic.

I will provide you with a selection of the best orthotics for kids with knock knees shortly, but first let me first show you which are the features that these orthotics will provide to your child’s feet and legs.

Orthotics for Knock Knees – The 4 Most Important Features!

These are the 4 most important features that the orthotics I will recommend below will provide to your child’s feet:

✅ Arch Support: Most children that have knock knees tend to be flat footed. You will notice how the orthotic will have a visible bump where the arch of your kids’ foot is supposed to sit. This will prevent your child’s foot from collapsing every time it comes in contact with the floor, and this is the first step in start aligning your kids’ feet and legs.

Let’s take a look at a picture of a flat-footed child and notice how the feet collapse (turn inwards):

Now let’s take a picture of the same flat-footed child standing in a pair of orthotics. Do you notice how much straighter the feet and legs are?

✅ Ankle Support: Rolled ankles (this means that the ankles turn inwards) can throw your child’s whole body out of alignment. You will notice how orthotics come with a heel cup in the back. This is where the ankle of your child’s feet is supposed to sit. Certain children have “rolled ankles” which means that the bone of the ankle (which is supposed to be straight), turns inwards or outwards. This is fully correctable if the orthotic is fitted with the correct pair of shoes.

Let’s take a look at a picture of a child with rolled ankles:

Do you notice how this condition is throwing the feet and legs out of alignment?

✅ Breathable: The orthotic must also be breathable in order to prevent bacteria from building up inside the shoes

✅ Molds to your kids’ foot shape: This orthotic is designed to mold over time to fit each child’s unique foot, it’s made of premium medical grade PU foam for kids with heel and arch support problems, and also made of a new soft step material that drastically increases comfort.

Please remember that this orthotic will work for mild cases of children with knock knees. If your child has a more severe case, then you will need to have your child fitted for an ankle brace orthotic. Fitting an ankle brace is very different from fitting an orthotic, and is not an easy task to do, but if you must do it from your house please reach out to me and I will show you exactly how to do it.

The Best Orthotics for Kids with Knock Knees ⭐⭐⭐⭐⭐

I only write reviews of shoe styles and orthotics that I have fitted before, otherwise I wouldn’t know how well-made they are, the amount of support that they provide, and how they fit.

Here you can find the best orthotics for children between the ages of 4 to 9 years old or shoe size 11 to 3.

Now that you know which are the best orthotic for kids with knock knees, you need to find a pair of supportive shoes that will accommodate the orthotic.

The shoes and orthotics work together in helping your child walk and run straighter. If you fit a pair of orthotics in a pair of unsupportive shoes, your child won’t get any of the benefits that the shoes have to offer and vice versa.

If you already have shoes at home, please make sure that they provide the 3 following features, which are the most important ones that the shoes must provide in order to be able to work with an orthotic:

✅ Substantial Sole: The shoes must provide a substantial, thick sole to hold the orthotic in place and reduce the impact that your child’s feet take every time they come in contact with the ground. Let’s take a look at a picture that will clarify what specific part of the shoe I am referring to:


✅ Firm Heel Counter: The shoes must come with a firm heel counter that will provide ankle support and work with the orthotic in reducing the impact that your child’s heels take every time they come in contact with the ground. A firm heel counter will also help straighten your child’s ankles. If you don’t know what the heel counter of the shoe is located take a look at the picture below for clarification:


✅ Depth: This is one of the most important features that the shoes must provide in order to work with an orthotic. Shoes that are deep will allow for the orthotic to sit deeply inside the shoes, and this will prevent giving your children the impression that their feet are coming out of the shoes. If the shoes are not deep enough, the top of your child’s feet (instep) will rub against the top part of the shoes. Let me show you the difference between that deep shoes can make when fitting an orthotics.

Both of these shoes have an orthotic fitted inside them for better visualization purposes.

Do you notice how in the New Balance shoe style (grey and pink) the orthotic is sitting down deeply while in the Asics shoe style (black) the orthotic is further up?

Here is another picture so you can see it more clearly:

This is what I mean when I mention that certain shoe styles are deeper than others.

I have put together a selection of kids’ shoes that provide all of these features in case you also need to provide your child with a pair of supportive shoes.

This selection of shoes fit ” true to size”, which means that you need to get your children a half a size longer of the size that they measure in the Brannock device (foot measuring device) in order to allow for growing room.

You probably notice how all of these shoe styles come with shoelaces instead of Velcro closure. The main reason for this is that shoelaces will provide more support and stability to your child and also make the orthotics fit better inside the shoes.

If you notice your child walking or running differently start by checking if his/her feet are turning inwards and if the knees are coming close to touching each other.
