OTC 1798 Air Walker Boot | Inflatable Low Top Walking Boot for Ankle Fractures, Sprains, Achilles Injuries & Foot Recovery

The OTC 1798 is a pneumatic walking boot designed for maximum foot and ankle stabilization during recovery from stable ankle fractures, foot fractures, severe ankle sprains (Grade II & III), Achilles tendon injuries, metatarsal fractures, stress fractures, soft tissue injuries, and post-operative rehabilitation.

The pneumatic air bladder is an internal cushion that you inflate using the integrated pump to customize the level of compression around your foot and ankle. As swelling decreases during recovery, you can adjust the air pressure to maintain a snug, supportive fit throughout the recovery process.

Use the integrated pump button or bulb (located on the boot) to add air until you feel comfortable, even compression around your foot and ankle. To release air, press the release valve. Adjust as needed throughout the day as swelling changes.

Yes. The OTC 1798 is designed to fit both the left and right foot, so you only need one boot regardless of which foot requires support.

Select your size based on your regular shoe size: X-Small (Women's 4–5), Small (Men's 5–6 / Women's 5.5–7), Medium (Men's 6.5–10 / Women's 7.5–11), Large (Men's 10.5–12 / Women's 11.5–13), X-Large (Men's 12+ / Women's 13+).

A rocker-bottom sole is curved from heel to toe, which helps roll the foot forward during walking without requiring the ankle to flex. This promotes a more natural gait pattern and reduces stress on the injured foot and ankle during recovery.

Yes. The rocker-bottom sole and shock-absorbing outsole are designed to allow safe, comfortable walking during recovery. Many users use a walking boot as a transitional device between a cast and normal footwear. Always follow your care provider's guidance on weight-bearing activity.

Yes. The OTC 1798 is commonly recommended for stable ankle fractures where immobilization and protection are needed while still allowing limited mobility. Always confirm with your care provider that a walking boot is appropriate for your specific fracture.

Yes. The OTC 1798 is widely used for post-operative foot and ankle rehabilitation. It provides the protection and stabilization needed during the early stages of recovery while allowing controlled mobility. Follow your care provider's specific post-operative instructions.

Wipe the exterior shell with a damp cloth and mild soap. The foam liner can be hand washed with mild soap and warm water and air dried. Do not machine wash, submerge the boot, or use harsh chemicals on any components.

Driving while wearing a walking boot is generally not recommended, especially on the right foot, as it may impair your ability to safely operate the brake and accelerator. Consult your care provider and check local regulations before driving with a walking boot.

Wear time depends entirely on your injury and your care provider's recovery plan. Fractures and post-operative recovery typically require 4–8 weeks in a walking boot, while sprains may require less time. Always follow your care provider's specific recommendations.

Yes. Wearing a clean, moisture-wicking sock inside the boot helps improve comfort, reduce friction, and maintain hygiene. A compression sock may also be recommended by your care provider to help manage swelling.

No. The OTC 1798 is not waterproof and should not be worn in the shower or submerged in water. Use a waterproof cast cover or follow your care provider's instructions for bathing safely during recovery.

Yes. Because the walking boot adds height to one foot, many users experience gait imbalance. A heel lift or even shoe for the opposite foot is often recommended to equalize leg length and reduce strain on the hip, knee, and lower back during recovery.

No prescription is required. The OTC 1798 is an over-the-counter walking boot available directly from Must online or at our showroom. However, we strongly recommend consulting a care professional to confirm it is appropriate for your specific injury.

Yes. The boot immobilizes the ankle and reduces stress on the Achilles tendon, which is essential for recovery from Achilles tendon tears, ruptures, and tendonitis. Your care provider may also recommend a heel wedge inside the boot to further reduce tendon tension.

Ensure the hook-and-loop straps are securely fastened and the air bladder is properly inflated for a snug fit. The non-slip outsole also helps maintain traction on most surfaces during walking.

Yes. Walking boots are commonly recommended for metatarsal and other foot stress fractures to offload the injured bone and allow recovery while maintaining limited mobility. Confirm with your care provider that a walking boot is appropriate for your specific stress fracture location and severity.
