Do You Have ‘Duck Feet’?

Published April 14th, 2022 by Integrated Physical Therapy

Take a look down at your feet. Do your feet point straight ahead, or do they point out? If your feet point out, this is what is commonly called being duck-footed. (Yes there is a more technical term, but for this we’re calling it duck foot)

How Can You Tell If You Have Duck Feet Posture?

Instructions:

  • Stand up.
  • March on the spot for 5 seconds.
  • Stop.
  • Look down at your feet.
  • Which direction are your feet pointing towards?

The Problem With Duck Feet

Depending on how low you have been standing and walking around like this, you may not notice any issues with it. BUT, If you have had it some time, it could be the reason why you are experiencing pain in your foot, knee, hip, or even low back lower back.

(This is not a conversation of which came first, the ‘Duck Feet” or the overactive hips. We’ll do that another time)

Having duck feet probably won’t kill you. It can mean you are leaving a lot in the tank at the gym or in your chosen sport. If none of the above pains has crept up on you, it increases your risk of pain in the future.

You see, the body is an amazing compensation machine. Whether you realize it or not. Every time you change your biomechanics (the way to move), it puts extra stress on surrounding tissues. Eventually, if you put too much stress on them, the dam will break, and pain will come flooding in.

So, What If I Have Duck Feet?

You may not consider your duck feet a problem. “It’s no big deal. Look at how many other people walk with the feet pointing out” (it is actually scary how common this is becoming). Next time you are in a busy place like the shops or on a busy street, look down at a few people’s feet. But just because everyone is doing it, it means that it is normal.

Having duck feet is a bit like driving a car around flat tires and your wheels out of alignment. You’ll get pretty crappy mileage, and the ride will not be smooth or comfortable.

What That Actually Means.

Turning a foot out causes the arch to collapse (pronate). The more your foot turns out, the flatter your foot will become.

When you walk, run, jump or squat, your body has to work harder to stop the arches of your foot from collapsing. This means your shin bone (Tibia & Fibula) will internally (inwardly) rotate, which can lead to overuse injuries of the muscle around your shin. Run your finger up the inside of your shin. Is it a little tender?

If your shin keeps rotating in, your leg will want to collapse. To counteract this, the Femur (thigh bone) externally (outwardly) rotates. Then to keep your thigh bone out, you end up recruiting your deep hip externally rotators (check out our previous blog for the hip muscles and their function) instead of your gluteal muscles (one of the reasons you need to do so much glute activation). This has a flow-on effect of an anteriorly (forwards) rotated hip and increased curve/stress on your lower back.

This should give you an appreciation for how much extra effort is for you to walk around and sit with your feet out all day. Now it’s time to dig a little deeper into the specific areas it affects.

Duck Feet: Your Ankles and Feet

Reduced Shock Absorption

The arch of the foot is designed to provide shock absorption when walking, running and jumping. It stores energy from your foot coming in contact (stored energy) with the ground and translates it into kinetic energy (movement).

When your foot is flat, your Plantar Fascia is under constant stretch (think heel pain in the morning). The Plantar Fascia is a band of connective tissue which helps form the arch of the foot. It works as an elastic band to keep us moving forward when walking or running.

Several muscles also work to help support the arch of the foot. We call these the intrinsic muscles of the feet (they have their origins and insertions inside the foot).

When your foot is rotated out, the arch is stretched and flattened. This puts these muscles into a lengthened position. These muscles also don’t have to work as hard as more of the foot is now resting on the ground.

They go on holiday and start sipping coronas on a beach in Mexico. This becomes an issue as your brain receives less neural feedback from your feet, leading to balance and joint proprioception (think joint positioning, kind of like satellite navigation for your car but in your brain).

This means the extrinsic muscles of the foot (muscles the originate outside the foot but insert into the foot bones), like the Tibialis Anterior, Tibialis Posterior, Flexor Hallucis Longus & Flexor Digitorum Longus, all have to work harder all day.

While the big extrinsic muscles of your foot can compensate for the movement part of your foot, they are lousy at controlling the small intricate movements of your feet, such as shock absorption.

Ankle Stability

The intrinsic muscles are also responsible for your ankle stability. They are quick and react to your foot being placed on uneven surfaces. They are also supposed to communicate with your brain to help with balance and make sure that they can react and save you from rolling your ankle or falling over when you do get a little unsteady. If you have ever rolled your ankle in the past, this is one of the major causes for the intrinsic muscles not communicating with the brain as effectively as they should.

To test this out, stand barefoot with your feet about hip-width apart. Slowly raise one knee to align with the hip, get your balance, close your eyes, and count to 30. If you feel like your going to fall over, open your eyes or do it next to something you can grab onto. Then repeat on the opposite side. If you can’t do this or look like you are swatting away imaginary flies, you need to wake your intrinsic feet muscles up.

So now that your feet have flattened, the shins start to rotate in. Your knees are excellent hinge joints (like a door) that swing open and closed but don’t like to rotate a lot. The inward rotation of your Tibia and outward rotation on the femur place increased stress on your medial collateral ligament (MCL), which is a ligament on the inside of your knee.

Why Do My Feet Turn Out?

Like many postural problems, flat out-turned feet can be split into two main categories.

It could be something you were born with, otherwise known as a congenital abnormality. Or it could be Acquired, something that has developed possibly due to; injury, disease or behaviour.

It is likely something you have acquired over the years as in Australia (at least) early screening will normally show up and congenital abnormalities.

Rolling your ankle is a pretty common way of decreasing the messages coming from your foot to your brain and decreasing the ability of the intrinsic foot muscle to lengthen and shorten. Other back injuries can cause inhibition of your Gluteals, or even something as common as sitting for extended periods of time can lead to tight hips and cause your feet to turn out.

What Can I Do About It?

If it’s a congenital problem, there honestly isn’t much you can do about it. It just means you have to make sure the other leg areas are in good working order and able to handle your compensations.

If the problem is acquired, and most are, then the good news is you can take back control of your body. Working in increasing foot proprioception (joint position), increasing glute activation, and strengthening up the lower limb will all pay for themselves in the long run. Our best exercises to help treat this common condition include:

  • Balancing the pelvis (this is key)
  • Rolling out your foot with a ball (golf ball works well)
  • Small Foot
  • Small Foot with ankle proprioception (move other Leg Forwards and back)
  • Glute Activation

If you can strengthen the problem areas and retrain your muscles to hold you in a better position, the body will naturally want to return to a more neutral posture.

As always, if you are concerned about your health and posture, go and get yourself checked out by a professional. If you found this article useful, please let us know and subscribe to our YouTube channel for videos and information like this.  www.youtube.com/IPTvirtual
