Ossur Rebound Air CAM Walking Boot – Tall High Top | Pneumatic Fracture & Ankle Boot
The Ossur Rebound Air Tall CAM Walking Boot is a premium pneumatic controlled ankle motion (CAM) boot with an integrated air bladder for adjustable compression and edema control. The tall high-top design extends above the ankle for maximum immobilization — ideal for ankle fractures, severe sprains, Achilles tendon injuries, and post-operative ankle and lower leg rehabilitation. For the short/low-top version, see the Rebound Air Short.
What this is (and what people call it)
This is a removable CAM walker boot with an integrated pneumatic air bladder. Many patients call it a cast boot, air cast boot, or fracture boot. It fits either the right or left foot — no side selection needed. The Rebound Air is Ossur’s higher-tier walking boot line compared to the Formfit Walker.
Short vs. Tall — Which height do I need?
- This boot (Tall High-Top) — Extends above the ankle for maximum immobilization. Best for ankle fractures, severe sprains, Achilles injuries, or post-surgical ankle rehab requiring more support.
- Rebound Air Short — Lower profile, best for forefoot injuries, toe and metatarsal fractures, or when less ankle restriction is needed.
🦺 Returning to Work? Closed-Toe Medical Boot for Workplace Use
Many patients recovering from foot or ankle injuries need to return to work in environments that require closed-toe footwear — including workplaces governed by OSHA foot protection guidelines. The Ossur Rebound Air Short and Tall CAM Walking Boots feature a fully enclosed, closed-toe design that covers and protects the toes during recovery.
Many patients have successfully used this boot to satisfy their employer’s closed-toe footwear requirement while recovering from a fracture, sprain, or post-surgical condition — allowing them to return to work sooner.
⚠️ Important Disclaimer: The Ossur Rebound Air CAM Boot is a medical orthopedic device and is not officially OSHA-certified or OSHA-approved footwear. It does not carry an ASTM F2413 safety toe rating. Whether this boot satisfies your specific workplace or employer’s footwear policy is a determination that must be made by you, your employer, and your occupational health or safety officer. Always verify compliance with your company’s requirements before returning to work. Consult your treating physician regarding your return-to-work status and any activity restrictions.

Size Chart & Fit Guide
Universal fit — fits left or right foot.
⚠️ Important: These Boots Fit a Size Range — Not a Single Shoe Size
CAM walking boots accommodate a range of shoe sizes — the extra room allows for bandaging, swelling, post-surgical dressings, and thick socks common during recovery.
- Choose the smaller size if swelling is minimal.
- Choose the larger size if you have significant swelling or thick bandaging. Use the air bladder pump to fine-tune compression.
When in doubt, go up a size.
📏 Measure Your Foot Length for the Most Accurate Fit
- Place a blank piece of paper on a hard floor.
- Stand with your heel touching a wall.
- Mark the tip of your longest toe.
- Measure from heel to toe mark in inches.
- Compare to the Internal Foot Length column below.
Tip: If you have swelling or a cast sock, add ¼”–½” and size up.
* Calf circumference: measure at the widest point of your calf. If your calf measurement puts you in a larger size than your shoe size, size up.

Frequently Asked Questions
Can I wear a CAM walking boot at work if my employer requires closed-toe footwear?
The Ossur Rebound Air Tall CAM Boot features a fully enclosed, closed-toe design that covers and protects the toes during recovery. Many patients have successfully used this boot to satisfy their employer’s closed-toe footwear requirement while recovering from a fracture, sprain, or post-surgical condition — allowing them to return to work sooner. However, this boot is a medical orthopedic device and is not officially OSHA-certified or OSHA-approved footwear. It does not carry an ASTM F2413 safety toe rating. Whether it satisfies your specific workplace policy is a determination that must be made by you, your employer, and your occupational health or safety officer. Always verify compliance with your company’s requirements and consult your treating physician regarding your return-to-work status before returning to the job site.
Is the Ossur Rebound Air Tall CAM Boot a closed-toe boot?
Yes. The Ossur Rebound Air Tall CAM Walking Boot features a fully enclosed, closed-toe rigid outer shell that covers and protects the toes. This closed-toe design is one reason many patients use this boot when returning to workplaces that require closed-toe footwear. It is a prescribed medical device, not an OSHA-certified safety boot, so patients must verify with their employer that it meets their specific workplace footwear policy.
What ankle and foot conditions is the tall CAM boot used for?
The Ossur Rebound Air Tall is prescribed for ankle fractures, Grade 2 and Grade 3 ankle sprains, Achilles tendon injuries and post-surgical repairs, stable lower leg fractures, and post-operative ankle rehabilitation. The tall high-top design provides greater immobilization of the ankle joint compared to a short boot, making it the preferred choice when the ankle itself is injured rather than just the forefoot or toes.
What does the pneumatic air bladder do and how do I use it?
The integrated pneumatic air bladder applies gentle, even compression around the foot and ankle to control edema (swelling) and improve fit as swelling changes throughout the day. Pump until you feel firm, comfortable compression — not tight or painful. Release air by pressing the valve if the boot feels too tight, especially in the morning when swelling is typically lower.
How long will I need to wear a CAM boot after an ankle fracture or sprain?
Wearing duration depends on the type and severity of the injury. Most Grade 2–3 ankle sprains require 4–6 weeks in a CAM boot. Stable ankle fractures typically require 6–8 weeks or longer. Achilles tendon repairs may require 8–12 weeks of progressive boot use. Your orthopedic surgeon or podiatrist will monitor healing with follow-up imaging and advise when it is safe to transition out of the boot. Returning to regular footwear too early is one of the most common causes of re-injury or delayed healing.
Can I shower or get the CAM boot wet?
The CAM boot itself is water-resistant but should not be submerged. For showering, most clinicians recommend removing the boot and using a waterproof cast cover or shower chair to keep the foot dry and protected, especially if you have a wound, surgical incision, or cast underneath. Never walk on wet surfaces in the boot without caution — the rocker sole can be slippery on wet floors. Always follow your surgeon’s specific instructions regarding bathing and wound care during recovery.
