Essential Tips for Safety, Comfort & Recovery

If you’ve been prescribed a CAM boot (also known as a moon boot or walker boot), it’s likely you’re recovering from a foot, ankle or lower leg injury—or in the post-operative phase of healing. While these boots are designed to protect and support your injury, they also come with specific care instructions to avoid complications and promote recovery.

Here’s everything you need to know while wearing a CAM walker.

1. Watch for DVT (Deep Vein Thrombosis)

CAM boots restrict ankle motion, which also reduces the natural pumping action of your calf muscles. This can slow circulation and increase the risk of blood pooling, leading to DVT—especially in those predisposed to clotting.

Contact your GP immediately if you notice:

  • New or worsening pain in the calf

  • Throbbing, cramping or tightness in the leg

  • Redness, swelling, or increased warmth

  • Sudden discomfort despite earlier improvement

2. Never Drive with a CAM Boot on Your Clutch or Brake Foot

The restricted movement can delay your reaction time and compromise safety. Remove the boot before driving and refit it once you’ve parked. Some insurers may reject claims if proper precautions weren’t followed.

3. Be Careful on Stairs

Balance can be affected in a CAM walker. Use the phrase “Up with the good, down with the bad” to remember which foot leads. Always use a handrail, and ask someone to support you until confident.

4. Keep the Boot Dry

Moisture under the liner can cause skin irritation or bacterial infection—especially for people with diabetes or post-surgical wounds. Avoid walking in wet conditions and cover your boot if necessary.

How to Wear a CAM Boot Correctly

Getting the Fit Right from Day One

A CAM boot is a vital part of recovery for many foot, ankle, or lower leg injuries—but only if it’s fitted and worn correctly. An ill-fitting boot can cause new issues like pressure sores, hip pain, or delayed healing. Below is a step-by-step guide to help you wear your CAM boot safely and comfortably.

⚠️ Important:
Always seek professional advice before wearing or purchasing a CAM boot. These are general guidelines and may not suit your specific injury or medical needs.

Step-by-Step Fitting Instructions

1. Prepare the Boot

  • Remove the soft liner from the hard outer shell.

  • Have a clean, seamless sock ready—preferably moisture-wicking or cotton.

2. Place Your Foot in the Liner

  • Slide your foot into the soft liner.

  • Smooth out any creases in your sock or liner to prevent skin irritation and pressure points.

  • Make sure your heel is tucked snugly at the very back of the liner.

3. Insert the Liner Into the Boot

  • Gently place your foot and liner into the hard shell. Be careful not to bump your injury.

  • The side supports (stays) should line up vertically along the centre of your lower leg.

4. Check Toe Placement

  • Your big toe should sit roughly one thumb’s width from the front edge of the boot.

    • If your toe overhangs, the boot is too small—risking further injury.

    • If your toe is too far back, the boot is likely too big and may cause tripping.

5. Align and Adjust the Boot Height

  • For tall boots: ensure the top edge sits below the crease of your knee for comfort and mobility.

  • Remove any white protective strips if they haven’t been taken out already (some models vary).

6. Add Extra Padding (if needed)

Use the included padding for added comfort:

  • Place under or over straps, at the heel, or beneath the toes.
  • Choose what feels most secure without causing pressure.

7. Secure the Straps Properly

  • Start with the ankle strap, then move to the foot, and finish working up the leg.

  • Straps should be firm, but not tight:

    • Too tight = restricted circulation

    • Too loose = foot slides around, increasing the risk of injury

8. Use the Air Pump (if included)

  • If your boot has a built-in air bladder, inflate it until the liner feels comfortably snug.

  • Don’t overinflate—it should support, not constrict.

How to Walk in a CAM Boot

  • Heel first: Step with your heel and allow the rocker sole to roll you forward naturally. It may feel awkward at first, but with practice it becomes easier.

  • Avoid limping—use a shoe balancer on your unaffected foot to match leg lengths and reduce strain on hips and lower back

  • Use crutches or a walking aid if recommended

  • Take it slow: Overdoing it can slow recovery or lead to compensation injuries.

Hygiene and Skin Protection

  • Always wear clean socks under the liner

  • Remove creases or folds that may cause irritation

  • Use padding provided by your podiatrist if you feel pressure at the heel or toes

  • Clean and air the liner regularly if your boot is worn long-term

Shoe Balancers, Crutches & Accessories

If your CAM boot causes a height difference between your legs, it can result in hip, knee, or back pain.
Always wear a shoe lift balancer on the non-injured foot to even out your posture—especially if you’ll be walking frequently.

Additional accessories such as Achilles wedges or crutches may also be recommended depending on your injury.

Professional Fitting Matters

CAM boots may look simple, but proper fitting and ongoing guidance are essential. Your podiatrist will:

  • Assess your injury and select the correct boot

  • Provide instructions for safe use

  • Adjust the boot to prevent pressure injuries

  • Guide you through recovery, including safe weaning and return to activity

Reception Staff Can’t Fit Your Boot

As helpful as front desk staff are, only a health professional can assess or fit a CAM boot correctly. Always book a podiatry fitting consultation to ensure you’re getting the right device and the right advice.
