CAM Walker Fitting
CAM Walker or ‘Moon Boots’ for Load Optimisation
CAM (Controlled Ankle Movement) Walkers, also known as ‘Moon Boots’, are crucial load optimisation tools.
They decrease the load, the movement and the work done by any number of different structures around the foot and ankle. CAM Walkers play an important role in injury recovery and rehabilitation.

Why You Wear a CAM Walker
CAM walkers are designed to immobilise the foot and ankle to allow for offloading and repair in a similar manner to a plaster cast — but they're removable for showering and rehabilitation.
Fractures of Foot & Ankle Bones
The rigid sole and supportive sidewalls minimise pressure on critical areas including the big toe joint, midfoot, heel, and ankle during fracture recovery.
Post-Surgery Immobilisation
After foot or ankle surgery, a CAM Walker provides the controlled immobilisation needed for healing while allowing removability for hygiene and rehab exercises.
Acute Trauma & Ankle Sprains
For acute ankle sprains and trauma, a CAM Walker reduces load and movement to allow damaged ligaments and soft tissues to heal properly.
Tendon & Fascia Pathologies
When tendons or fascia require aggressive load reduction to heal, a CAM Walker provides the offloading needed. This includes conditions like severe plantar fasciitis and Achilles tendon injuries.
Growth Plate Fractures in Children
Paediatric growth plate fractures require careful immobilisation. A CAM Walker protects the growth plate while being adjustable as the child heals.
Nerve Compression Pathologies
Some nerve compression conditions in the foot and ankle benefit from the reduced load and movement a CAM Walker provides during treatment.
How to Fit & Walk in Your CAM Walker
Proper fitting is essential for your CAM Walker to work effectively. Follow these steps for the best results.
Place your leg into the walker with your heel positioned at the back
Close the liner firmly around your foot and leg
Fasten the middle strap over your foot near the ankle through the 'D' ring
Secure the strap closest to your toes, then work upward. All straps should be firm without causing discomfort
When walking, keep the walker pointing forward, take shorter strides, and avoid stairs initially
Care & Precautions
Wear Socks
Wear socks to protect the liner from sweat and keep the boot fresh. Compression socks may be prescribed to reduce swelling.
Keep It Clean
Hand wash the liner gently if needed. Elevate your foot regularly to reduce swelling and promote healing.
Other Foot Footwear
Wear stable, supportive footwear on your uninjured foot. Try to match heel heights between the boot and your shoe.
No Driving
You cannot legally drive while wearing a CAM Walker boot. Arrange alternative transport for the duration of your treatment.
DVT Risk
Extended use increases the risk of deep vein thrombosis (DVT). If you experience extreme heat or leg pain, seek hospital care immediately.
Fall Prevention
You may experience balance issues due to limited ground contact. Consider using crutches or assistive devices for safety.
Frequently Asked
Questions.
How long do I need to wear my CAM Walker for?
+The length of time you need to wear your CAM Walker depends on your specific injury. Some people wear their CAM Walker daily for two weeks, while others may need it for several months. Your podiatrist will provide you with expected timelines based on your condition.
Can I take my CAM Walker off to sleep?
+This depends on the type of injury you have. If you have a fracture, you will often need to wear your CAM Walker at night, at least initially. For soft tissue injuries like plantar fasciitis, you can usually remove it for sleeping from day one. Your podiatrist will advise you.
What happens when I am ready to come out of the CAM Walker?
+Usually, towards the end of your time in the CAM Walker, your podiatrist will have been prescribing exercises to maintain soft tissue strength. The next step typically involves transitioning to structured shoes and orthotics based on your individual needs and recovery progress.
Can I drive while wearing a CAM Walker?
+No. You cannot legally drive while wearing a CAM Walker boot. You will need to arrange alternative transport while you are wearing it. Please plan ahead for work and appointments.
Will my muscles weaken while wearing the boot?
+Your quadriceps will work harder while wearing the boot, which may cause some fatigue. Your podiatrist will prescribe exercises to maintain strength throughout your recovery and ensure a smooth transition out of the boot.
