​One day I was reading a research paper published at NIH.Gov about the peroneal tendonitis and its effects on peroneal tendons.

This research particularly emphasizes the importance of wearing a cast or a walking boot or ankle braces as a post-operative care for people having peroneal tendonitis.

Many podiatrists recommend the use of walking boots for post-operative surgeries for foot injury and tendonitis condition. One such popular walking boot type is CAM Walker Boot.

Today, we are going to discuss more about this walking boot. I will put forth some points regarding the effectiveness of Cam Walker boot for treating peroneal tendonitis and the other foot injuries quickly and efficiently.

The question is does it really help in quicker recovery of various foot fractures and leg injuries.

Let me explain more about it in this complete guide.

​What is a Cam Walker Boot?

​If you are completely new to the concept of using specially designed walking boots for treating peroneal tendonitis, then don’t worry.

Here, you will get a complete idea about its actual functions and benefits.

Basically, a CAM Walker Boot simply means Controlled Ankle Motion Walking Boot. Sometimes, it is also called as Below Knee Walking Boot.

It is a specially constructed walking boot for people who are suffering from various foot ailments such as ligament tears, tendonitis, ankle sprains and foot fractures.

Its main function is to adjust or balance your foot weight.

When you suffer from foot fractures or sprains or tendonitis, your foot requires maximum protection, comfort and support. These boots help expedite your recovery process.

​How These Walking Boots Work?

​These boots actually function as a helpful orthopedic device.

When you experience a severe foot injury or ankle sprains or foot disorders such as peroneal tendonitis, then your ankle movements need to be restricted to a certain extent if you want faster recovery.

Sometimes, you undergo a serious foot surgery or there is a removal of cast.

In this condition, your orthopedic surgeon or a podiatrist can prescribe you to use a reliable Cam Walker boot.

These boots actually help you to maintain a proper foot balance and prevent uneven pressure disbursement.

They mainly help in controlling or limiting the unwanted foot or ankle movements. This is important to avoid further escalation of your foot injury.

​How to Use Cam Walker Boots?

​There are basically 4 main components of any Cam walking boot. They are as follows.

1. There is a hard and durable plastic shell on the outer side of the boot. It offers improved protection for your foot and strength for the walking boot.

2. There is a strong frame located in the lower side of the boot. It is important in restricting the overall ankle movements.

3. Then, there is a comfortable and soft internal fabric lining. This lining comes with hook and loop fasteners. It provides more comfort, support and cushioning for your injured foot muscles.    

4. Finally, the boot is well equipped with adjustable closures. They offer the best secured fitting. They are essential in making custom fit and for comfortable walking experience.

Now, if you look at this boot carefully, then you will see that its one-piece construction mainly opens  down the front. You can insert your foot inside the boot comfortably.

Once your foot is inside the boot properly fitted, you can use its Velcro straps to make secured fitting.

This Cam walking boot also comes with 2 aluminium mechanisms. Both of them are located on either sides of your foot ankle.

These 2 systems are well connected through a joint mechanism. This joint mechanism, in turn, is well connected to the sole of the walking boot.

The joint mechanism mentioned here is of the paramount importance as far as treating foot injuries is concerned. Because it allows us to control the movements of our ankle comfortably.

If you want, you can completely stop the movements of your ankle by controlling this joint mechanism.

You can even set this mechanism in such a way that your ankle’s range of motion can be  maintained from 2 degrees to 45 degrees. (

Thus, the most important function of any cam walker boot is to maintain or adjust plantar flexion and dorsiflexion.

And by controlling these two types of ankle movements, you can gradually improve the foot conditions such as peroneal tendonitis and foot fracture.

​What are the Different Benefits of Cam Walker Boots?

​The important uses or benefits of wearing cam boots are as mentioned below.

1. Equal Pressure Disbursement: These walking boots help the injured person to equally distribute its foot weight while walking. This prevents further escalation of your foot injury and gradually reduces the foot pain.

2. Proper Air Ventilation: There are ultra light and heat moldable semi-rigid shells present inside these boots.

They help in proper air ventilation inside the boot. This is important in preventing moisture and excessive sweating on your feet.

4. Offers Natural Gait and Foot Stability: The overall design and build of this boot provides the best foot balance.

​Can You Wear These Boots on Either Foot?

​Depending on the foot injury or foot fracture type, these walking boots come in different styles and configurations. You will see variety of these boots in terms of their height, comfort, cushioning and fitting features.

Most of the boot manufacturers today produce universal fitting boots. This means you can wear a single boot either on right foot or left foot without any issues.

​Can You Wear Socks in a Walking Boot?

​You can wear socks under walking boots with no issues. If you want, you can also just wear boots without any socks.

But there are certain advantages of wearing specially designed socks for such types of walking footwear.

1. Moisture Wicking Liner: The socks that are designed to wear with these boots come with moisture-wicking liner.

This liner helps in absorption of excessive sweat and keeps your feet sweat free and breathable for longer period of time.

Not just cam walker boots, but you can wear these types of socks for post-operative surgical footwear, closed toe walking shoes, air cast walking boots and orthopedic boots.

2. Greater Support and Comfort: These socks are also very essential in providing the required support and comfort for your feet in case of foot fracture, broken bones, bunions, plantar fasciitis, etc.  

3. Prevention of Blisters and Chafing: Sometimes, the brace of these walker boots rubs with your skin badly if you don’t wear it properly.

This constant rubbing can lead to skin irritation, chafing and eventually to blisters.

If you want to prevent these unfortunate skin issues, then wearing thick socks is just the solution you need for this.
