Worried about How To Measure Foot Arch? This is a detailed research on how to measure foot arch size. It contains how to measure foot arch height. If your preference is how to determine foot type, then this article is perfect for you.

Most People Can Be Categorized Into Three Arch Types: Normal Arches, High Arches, And Flat Feet. Ideally, The Arch Of Your Foot Curves Slightly Upward, Which Balances Weight And Impact Optimally And Keeps Your Foot Muscles And Ligaments Healthy.The height of a person’s arch is determined by the height of the navicular bone. Collapse of the longitudinal arches results in flat feet. A person with a collapsed longitudinal arch will likely over-pronate.

This rolling inward of the foot can place additional stress and strain on the plantar fascia. A person with a high longitudinal arch essentially has a tripod type foot. The majority of the pressure will be placed on the heel, first and fifth metatarsals. A person with a high arched foot is also at risk for developing plantar fasciitis and other conditions due to the increased tension on the plantar fascia. Your plantar fascia plays a critical role in absorbing the impact from physical activity, distributing your weight evenly, and allowing you to move without pain.

Why Does My Arch Type Matter?

It’s important to know your arch type for several reasons. Most importantly, knowledge is power! Finding out whether you have normal arches, flat feet, or high arches provides you with the information you need to make good choices when buying new shoes and preventing injuries like plantar fasciitis.

Figuring out your arch type is easy, and can be done in just a few seconds!

Take the Foot Arch Test

The foot arch test is a simple way to determine whether you have flat feet or high arches! Just follow these easy instructions:

  • Pour water into a shallow pan (the pan should be big enough to fit your foot, and the water should be just deep enough for all parts of the bottom of your foot to get wet).
  • Step into the water with one foot, then carefully remove your foot from the pan of water and step onto a flattened brown paper bag or piece of cardboard that will show your footprint (don’t just lightly place your foot onto the paper bag/cardboard. Be sure to put your weight on it!).
  • Remove your foot from the bag/cardboard and take a photo for reference
  • Repeat the process with your other foot

What Do My Results Mean?

Carefully examine your footprints, or the photos you took of them. You should see one of three basic imprint types:

Normal Arches:

If the middle portion or arch of your footprint is just about halfway filled in with a noticeable curve along the arch, congratulations! Your arches are at the proper height to absorb and distribute the impact from walking and other physical activity.

Inserts Recommended for you: Original Heel Seats

High Arches:

High Arch wet test

If all you see in your footprint is your heel, the ball of your foot, and your toes (without much in between), you have high arches. This means your feet have an extra hard time absorbing impact and need extra cushioning and proper arch support.

Inserts recommended for you: Full Length High Arch Heel Seats

Flat Feet:

Flat foot arch wet test

If your footprint looks like a complete foot (i.e., is totally filled in without much of an inward curve in the center), you likely have flat feet. This causes you to “pronate” when you walk or run (meaning, your foot rolls inward)–which is great for shock absorption but not so great for your knees and legs, or your chances of developing plantar fasciitis as your arch is strained.

Inserts Recommended for You: Original Heel Seats

How Else Can I Tell If I Have High Arches?

In addition to footprint test, you likely have high arches if you experience pain in the heel and ball of your foot, especially after running or other high impact sports, since high arches mean your feet have a harder time absorbing impact. High arches are much less common than flat feet, but supporting your high arch is no less important!

Ultimately, visiting your podiatrist will always provide you with the most accurate information about your foot type. Your podiatrist will be able to perform an in-depth foot exam and gait analysis to give you the most accurate diagnosis and treatment plan for any symptoms you are experiencing. 

How Else Can I Tell If I’m Flat-Footed?

More signs you have flat feet include feet that tire easily when standing, aches and pains localized in the arch and heel of your feet, and swelling on the undersides of your feet. Another telltale sign of flat feet is that standing on your toes may be quite difficult.

How Else Can I Test Pronation?

If you’re worried you have flat feet and pronate when you walk or run, try the following tests:

Take a look at the outsoles of an old pair of running shoes. If you notice a lot of wear along the inside of the sole’s outside edge, it’s pretty likely your foot is rolling inward heavily as you walk or run.

Ask a partner to help you test for possible pronation. Stand on a flat surface and ask your friend to see if he or she can slide one finger beneath the arch of your foot. If not, it’s likely you have flat feet and are pronating when you walk! 

Which Shoes Should I Wear for My Arch Type?

Shoes for arch type

Normal Arches:

Keep your arches in great shape with shoes that have firm, thick soles, proper cushioning, and keep your heel stabilized (your heel should sit snugly in the back of your shoe).

Flat Feet:

If you have flat feet, it’s extra important to buy shoes that keep your foot from rolling inward, or pronating excessively. Look for shoes with a thick, cushioned sole and lacing that allows you to restrict movement in the shoe. Add support for the flattened plantar fascia with Heel Seats. 

High Arches:

Shoes with cushioning are extra important if you have high arches. The shoes you’re looking for are typically heavier on cushioning and less rigid. Slip in high arch supports to help redistribute weight more evenly along the bottom of the foot.

High or flat arches are nothing to be ashamed of. Everyone’s feet are different! Taking ownership of your foot type by properly supporting it with the right shoes and orthotics is the ticket to avoiding plantar fasciitis and enjoying pain-free activity. Heel Seats give your arches the support and cushioning they need–no matter their height! Whether you have high arches, normal arches, or flat feet, there’s an arch support insert just for you. If prefabricated orthotics do not completely eliminate your foot pain after about one month, schedule an appointment with your podiatrist. 

Are Your Feet Still Growing?

Are you wondering why you are wearing bigger shoes as you get older? Do you think you feet are getting bigger?  Well, that is because they are getting bigger

Nearly 100% of us will need bigger shoes as we get older. Essentially what is happening is that over time our feet slowly flatten out. As they flatten, the arch lengthens and your feet get longer. In addition they splay out and your feet get wider.

Since your feet are getting bigger, you should be wearing larger shoes as you get older. If you are still wearing the same shoes you wore 10 years ago, we can pretty much guarantee that they are too small.

Besides Age, Why Else Do Feet Get Bigger?

1. Weight gain can cause feet to get bigger

If you are carrying extra weight, you are going to carry extra fat everywhere including around your feet with the result of larger feet.

2. Pregnancy can cause feet to get bigger

During pregnancy the same hormones that relax the ligaments of the birth canal also relax the ligaments in the rest of your body including the feet. Since the feet are carrying extra load during pregnancy due to normal weight  gain, the feet will often flatten leading to lengthening and widening of the feet.

How to Stop Your Feet from Getting Bigger

There may not be a way to completely stop your feet from getting bigger. But you may be able to slow the progression. Below are our best suggestions of what you can do to combat the flattening of the foot that occurs with aging, weight gain and pregnancy.

Please read this important disclosure about the products recommended in this article.

1. Use arch supports in your shoes

By using arch support to stop the flattening of the feet you may be able to stop or slow the splay that leads to feet getting bigger. The key is to get an arch support that conforms very close to the arch of foot. The closer it grabs your arch the better it will be at stopping your foot from flattening and splaying. Another way to look at this is to wear the highest arched orthotic you can tolerate.

Custom orthotics that are made to betotal contact to the arch of your footwill provide the best support and protection. There are, however, some very good over-the-counter arch supports that will offer excellent protection.

Over-the-Counter Orthotics with the Best Arch Support

For athletic shoes and walking shoes try the FootChair Plus Orthotic with adjustable arch height.  It has a great arch to help stop flattening of the foot plus pads that can be used to increase the arch for even more support. This may help stop the foot from getting bigger over time.

For smaller casual shoes and small athletic shoes (such as soccer cleats) try the smaller version – the FootChair 3/4 Length Orthotic.

For women’s dress shoes, the FootChair Slim Orthotic with Adjustable Arch Support is also is the one we recommend to our patients. This is by far the best OTC arch support we have found for women’s flats and dress shoes. It has a great arch support, a very slim profile and flexes to adapt to most heel heights.

Here is a list of all of our recommended prefabricated orthotics.

2. Wear arch support sandals or slippers anytime you are not wearing shoes

Vionic flip flops with arch support

At times that you are not wearing shoes, for example when in your house, wear sandals or slippers with arch support. The is particularly important if you are on hard, flat surfaces such as hardwood floors.

These arch support sandals will help prevent flattening and splaying of your feet.

The sandal brand with the most supportive arch is currently Vionic. You can see a selection of Vionic sandals and slippers here.

The key to avoiding flattening of the arch is to wear arch support as much as you can – even when at home.

3. Custom orthotics offer more protection against feet getting bigger

If prefabricated orthotics are not providing enough support, we can prescribe use a custom orthotic. Custom orthotics will conform closer to the arch of the foot, so they do a better job stopping your feet from flattening out. In particular a “total-contact orthotic” that hugs the arch of the foot very close will help the the arch from flattening the foot from getting longer.

If you are in the Seattle area contact us for an appointment to find out if you are a good candidate for custom orthotics.

4. Wear stable shoes

Stable shoes that don’t flex too much will also help support your feet and prevent the flattening that leads to larger feet. Our list of recommended shoes can be subscribed to here.

5. Have your feet sized when you buy shoes

Go to specialty shoe stores with well-trained staff and believe the clerk when they tell you that you are no longer a size 8.

6. Lose weight to shrink your feet

Extra weight puts a lot of flattening force on the foot. If you can take off a few pounds you will decrease those harmful forces on your feet.

So our general recommendation is that it is good idea to wear arch supports or custom othotics to help prevent the foot from flattening over time. Stable shoes will also help. These suggestions will probably help slow or decrease the enlargement of your feet, but  regardless of what you do you will probably need a somewhat larger shoe as time progresses.

Most Important for Preventing Your Foot From Splaying and Getting Bigger

If you want to try to limit how much your foot splays out the most important things you can do are to ALWAYS wear arch support as described above and, if you are overweight, then lose some weight.
