AirCast AirLift™ PTTD Ankle Brace

An off-the-shelf brace, the AirLift™ PTTD Brace is designed for the treatment of posterior tibial tendon dysfunction (PTTD), or for early signs and symptoms of the adult acquired flat foot. Depending on the severity of the condition, it can be prescribed for use as part of a conservative treatment to stabilize the condition and help prevent its degeneration, or post-surgically and during rehabilitation.

It features an integrated aircell, located underneath the sole, which is adjustable using an inflatable hand bulb (included with brace). When inflated, the aircell can accommodate different arch heights and comfortably lifts underneath the arch to achieve a more natural foot position to help provide posterior tibial (PTTD) relief.

The AirLift is designed for easy application and adjustment. The brace uses an innovative rear entry design which allows the patient to slip their foot into the back of the brace. Two straps secure the brace and can be used to adjust fit. These patient-friendly design elements make the AirLift easier to apply than custom braces, eliminate time consuming lacing, and help improve patient compliance.

The Aircast AirLift brace is suited for Posterior tibial tendon dysfunction, adult flat foot, post-op use.

Aircast AirLift PTTD Brace Features:

  • Adjustable arch aircell for individualized comfort and control.
  • Anatomically designed shells for secure ankle stability.
  • Rear entry design for convenience.
  • Two strap application for use of use and compliance.
  • Made from latex-free neoprene material.
  • Available in three sizes - please see our sizing chart tab above for correct sizing guideline information.

The Aircast Airlift PTTD brace can be used for:

  • Posterior Tibial Tendon Dysfunction (PTTD).
  • Posterior tibial tendonitis.
  • Adult-acquired flat feet.
  • Post-Op/Rehabilitation.

What Is Posterior Tibial Tendon Dysfunction ("Acquired FlatFoot")?

Posterior tibial tendon dysfunction (PTTD) is an inflammation and/or overstretching of the posterior tibial tendon. Its function is to help support the arch, but in PTTD, it's unable to perform that job efficiently, often resulting in flattening out under the sole.

This fibrous cord extends down from a muscle in the leg. It descends the down the lower leg and runs along the inside of the ankle and then down the side of the inside aspect of the foot. It is one of the most important supporting structures and helps displace weight properly while walking.

PTTD is often called “adult-acquired flatfoot” because it is the most common type of condition usually developed during adulthood. This condition typically occurs in only one foot, but some people can develop it in both. PTTD is considered a progressive condition, which means it will keep getting worse, especially if not treated early by a medical professional.  The Aircast AIrLift PTTD brace is appropriate for stage I/II PTTD symptoms.

  • Durable nylon material is used in the boot itself along with the half figure eight, arch-supporting strap.  Semi- rigid aircells on the sides provide additional ankle/rearfoot stabilization. Note this product has a one way valve on the side to inflate the pillow under the arch.  Push the end of the inflation air bulb into the valve assembly just enough to inflate the product. Jamming the inflation bulb deeper and deeper into the valve assembly will bend the one way valve inside and cause a slow leak to occur.  This is the #1 issue that we get calls about so just be gentle blowing it up and it will last forever.


Works great!
I had a bad case of tendinitis. Using this brace has allowed me to get back on my feet and walk around without pain. It fits comfortably in an athletic shoe and the pump allows you to adjust it to give your arch the right amount of support. The support tech helped me to decide on the right size for a good fit. I'm very pleased with this purchase.

Best service, very good brace
Very useful cast for PTTD injuries, take into consideration that it won't fit all your shoes. Customer service was responsive, delivery fast.

Inflates underneath my arch
Received this brace and it properly right out of the box. It inflates easily. Seems to be helping after two weeks of use.

Relieves the pain, but a little fiddly to get just right. the straps and the air bladder have to be properly positioned and inflated so as not to cause pain but relieve the pain it was purchased for. Also have to find the right shoes to fit all this into comfortably. Once you get it right, and with some practice putting it on is quick. The price at DME Direct is way lower than through the foot Doctor.

Great ankle brace with pump
The doctor recommended that I use this aircast ankle brace with pump to help boost my arch support. I have grade I PTTD and this helps my arch support immensely. The pump is very easy to use and straight forward.

Overall Good
This was probably the best purchase I could have made for relief of the ankle pain I was experiencing. The orthotics were not helping at all. The relief was almost instant. I did make 1 modification. The outside of the ankle brace kept sliding forward since there is nothing to hold it in place. So I took a piece of velcro and went around the back at the top like the piece at the bottom. Helped a lot. I now wear my Aircast AirLift every day to work and am on my feet 5-6 hours each day. Thanks for the great product.
