Cam Boot vs Moon Boot: Complete Guide to Walking Boots & When to Use Them
Table of Contents
What is the Difference Between Cam Boots and Moon Boots?
The truth is, there's less difference than you might think. When it comes to types of foot and ankle braces, many name variants refer to the same brace (or boot). You might have heard of the names Camboot, CAM Boot (controlled ankle movement boot), CAM walker, moon boot, below-knee walking boot – these are all inherently the same thing, just described by their location and purpose.
What is a CAM Boot?
A camboot, also known as a walking boot or medical walking shoe, is a type of orthopedic footwear used to immobilise the foot and ankle after an injury or surgery. It is designed to provide support, stability, and protection to the foot and lower leg during the healing process.
These boots are made of a rigid sole, which prevents the foot from flexing, and adjustable straps or Velcro closures allow for a customised and secure fit. Camboots are usually bulkier and more supportive than regular shoes, and they come in various styles and designs to accommodate different types of injuries and foot shapes.
Understanding Foot and Ankle Movement
The ankle and foot are capable of movements in different directions. This allows you to walk, run, jump, stand on one leg, play sports, etc., with power and control. The ankle can be:
Pulled back towards the body (dorsiflexion)
Pointed away from you (plantar flexion)
The soles of the feet can also face slightly towards or away from one other (inversion and eversion). The foot itself is controlled by many small muscle groups and other connective tissues that form the arch structure in the sole. This arch can flatten (pronation) or lift, creating space underfoot (supinate) during walking.
The main takeaway: When you're on your feet and doing activity, a lot of movement continually occurs. This is where walking boots become essential for injury recovery.
When Do You Need a Walking Boot?
What Does a CAM Boot Do?
The primary purpose of a cam boot is to reduce weight-bearing on the affected foot or ankle, promoting proper healing and preventing further damage. They control and limit any lower leg, foot, or ankle movement and take pressure away from the area's bones, muscles, ligaments, and tendons, allowing an injury to heal.
Depending on the type and extent of injury, you might need to wear a CAM boot to offload the injured site, reduce pain and swelling, and help speed up recovery. Sometimes, they are a more practical, comfortable, and hygienic alternative to crutches or plaster casts.
Specific Injuries Requiring Walking Boots:
High-grade ankle sprains: There has been moderate to severe damage to one or more ligaments in the ankle. These will be painful and feel unstable to stand/walk on. Learn more about ankle injury recovery.
Achilles tears or ruptures: Grade 2 tears might indicate using a CAM boot without surgery. Otherwise, a grade 3 (or complete) tear will require surgery first, followed by time in a CAM boot.
High ankle sprains and syndesmosis injuries: These are classified as either stable or unstable injuries. If there is no associated fracture and damage is very mild, it can usually be managed in a CAM boot without surgery.
Foot fractures: Some common fracture sites include those in the midfoot area and lower end of the shin bone (tibia and fibula). Foot fractures typically require 4-6 weeks minimum in a boot.
Following surgery: Anywhere between 6-8 weeks, depending on the injury and how well the surgery went.
Severe Plantar Fasciitis: Severe inflammation and tears in the plantar fascia may require immobilization.
Lisfranc Injury: Involves the ligaments and bones that give the arch of the foot its integrity.
Tibia or fibula stress fractures: These bones take around six weeks to heal and require protection during this period.

How Long Should You Wear a Walking Boot?
Do I Leave a Camboot or Moon Boot on All the Time?
The short answer is yes. If you need to be in a CAM boot or moon boot at all, then it is likely that you will need to be wearing it 24/7 to start with. Some rough timeframe estimates for how long you might be in a boot could range from 2 weeks to 2 months.
Factors Affecting Duration:
1. Location of injury: Usually based on how much load is put through that site. Structures that give the arch of the foot its integrity are placed under more load and require longer protection.
2. Severity of injury: Injuries can be described as mild through to severe. They are also classified based on whether the damage occurs during a one-off incident (acute injury), was developed over a more extended period (chronic injury), or has been an issue in the past but recently worsened.
3. Type of injury:
Fractures: Depending on location and stability, these must be in a Camboot for at least 4-6 weeks
Ligament & Soft Tissue Injuries: Because there is less blood oxygen supply to these tissues, they are slower to recover, roughly 6-8 weeks or more
Typical Progression Timeline:
Week 1-4: Full-time boot wear (24/7)
Week 4-7: Part-time wear as healing progresses
Week 7+: Gradual transition with increased physiotherapy exercises
For example, you might start in a Camboot full-time for 3-4 weeks, then go part-time for 2-3 weeks, then spend progressively more time out of the boot with a stronger focus on rehabilitative exercises and minimal/no bracing, such as the use of an ankle guard or Kinesio tape.
Proper Usage and Care Instructions
Should I Sleep with a Camboot On?
Yes, you will likely need to wear a moon boot 24/7, including throughout the nighttime. The boot should protect the joint so that while you are asleep and unaware of how the ankle/foot is positioned, it doesn't risk further irritation.
For example, if you've badly sprained your ankle, you want to limit the amount of stretch that goes through that ankle's front and outer side. While you're asleep in a relaxed state without being in a boot, the ankle is vulnerable to naturally moving into a position of stretch, plus the additional pressure of the sheets.
Is it OK to Walk in a Camboot?
Yes, continuing walking while you are in a Camboot is fine. These were initially designed as a more practical option to a cast so that you can safely continue working and participating in other social commitments as you recover.
Important tip: Try to find the right shoe to wear on the other foot to match the height of the CAM boot. This will prevent issues elsewhere in the body. The opposite hip and lower back are common areas that tend to become affected by discrepancies in shoe height.
Is it OK to Walk in a CAM Boot Without Crutches?
Surgeons usually recommend that surgeries for injuries like an Achilles rupture, syndesmosis injury, or ankle fractures be "non-weight bearing" for a short duration. In these cases, you may need to be in a CAM boot while using crutches to remove all external loads.
Once your surgeon or specialist clears you that it is safe to bear weight, yes it is okay to walk in a CAM boot without crutches.
Daily Care Instructions:
Remove and clean the liner daily - allow to air dry
Inspect straps and buckles for wear or damage
Keep the boot dry - use waterproof covers in wet weather
Check skin regularly for pressure sores or irritation
Maintain proper hygiene to prevent infections
What Are Cam Boots Made Of?
Camboots are typically constructed from a combination of materials to provide optimal comfort, stability, and protection:
Outer Shell
Hard plastic construction offering a sturdy and protective layer around the foot and ankle
Rigid sole design that prevents foot flexing during healing
Interior Components
Foam liner that provides cushioning and comfort
Removable innersoles that can be customized for enhanced support
Padded interior ensuring the injured area is adequately supported
Fastening System
Adjustable straps and fasteners (often Velcro) for secure, customized fit
Multiple adjustment points for proper immobilization
Sole Construction
Built-in 'rocker' sole that allows continued walking with minimal limb movement
Durable rubber material providing traction and support
Non-slip design for safety during use
Additional Features
Metal supports or hinges in some models for extra ankle stability
Breathable materials to reduce moisture buildup
Lightweight design despite robust construction
This combination of materials ensures cam boots provide the support, protection, and comfort required for individuals recovering from foot or ankle injuries.
Recovery Timeline and Expectations
Alternative to Traditional Casts
Sometimes walking boots are a more practical, comfortable, and hygienic alternative to crutches or plaster casts. They have a standard in-built 'rocker' sole that intrinsically allows you to continue walking with little limb movement.
Comparison with traditional casts: Fibreglass and plaster casts are used in hospital settings, usually following surgery for displaced fractures or an Achilles rupture. These are more supportive initially and prevent all ankle and foot movements. At some point in your early recovery stage, you may transition into a Camboot, as early mobilization provides better long-term outcomes following injury.
Gradual Return to Activity
A gradual build-up in exercise demand and intensity must be done consistently to re-strengthen the joint during recovery. If you are returning to sport/activity, you may use an ankle guard for a while – this comes down to individual preference, usually based on what is most comfortable and gives you the most confidence.
Professional guidance is essential: This progression will be guided by your physiotherapist, sports doctor, and surgeon collaboratively alongside other approaches to return to full function.

Frequently Asked Questions
Q: Can I drive while wearing a walking boot?
A: Only if the boot is on your left foot and you drive an automatic car. Never drive with a boot on your right foot - it's unsafe and may void insurance. Consider alternative transport during recovery.
Q: What if my walking boot causes pain or numbness?
A: Some initial discomfort is normal, but persistent pain, numbness, or skin irritation requires immediate medical attention. Contact your healthcare provider or visit our clinic for assessment.
Q: Can I get my walking boot wet?
A: Most boots aren't waterproof. Use plastic bag covers for showering or purchase waterproof boot covers from medical suppliers.
Q: How do I know when to stop using my walking boot?
A: Only stop when cleared by your healthcare provider. Premature removal can cause re-injury or delayed healing. Your physiotherapist will guide the transition process.
Q: Can I exercise while wearing a walking boot?
A: Upper body exercises are usually fine, but check with your physiotherapist before any activity. Learn about safe exercise during recovery.
Q: What's the difference between weight-bearing and non-weight-bearing?
A: Non-weight-bearing means no pressure on the injured foot (use crutches). Weight-bearing allows walking in the boot. Your surgeon will specify which applies to your injury.
