Anatomical Design Helps Realign & Support the Ankle

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.

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.

Product Features and Benefits

  • AirLift integrated aircell and semi-rigid shells provide foot support and ankle stabilization
  • The aircell (located under the foot) accommodates variances in arch shapes and heights to lift the foot arch for a more natural foot position
  • The aircell has been tested with 2,000lbs of pressure, so it can be worn during sports and other active-related activities
  • Recommended to be worn with an athletic or walking shoe as the brace may be slightly bulky
  • Aircell inflation can be adjusted while worn on foot
  • Not recommended for patients with inversion sprains or fractures
  • Made of neoprene material (latex-free)
  • Hand pump included
  • Care: Hand wash with mild detergent, rinse with tap water and air dry


  • Posterior tibialis tendon dysfunction
  • Adult acquired flat foot
  • Post-op rehabilitation
  • Pronation

Aircast Airlift PTTD Brace reviews

This aircast has been great - I wear one everyday for @2years now. It has enabled me to be active - long walks, hike, normal life, with 90% less pain. I have gone through several. - Julie
Walking Grandma
My podiatrist put me in the first Aircast PTTD brace. I immediately felt relief. Bought a second one from to make it easier to wash and air dry. I wear the brace about 14-16 hours a day and have used it for over 4 months. I have improved so much that I am not tearing up at the thought of going to the grocery store or any where else for that matter. I have reached the point of being able to stay on my feet for several hours at a time. I expect more improvement and complete healing. What a great product. - Walking Grandma
The cast works great, but after six months of use it began leaking air. Now it hold now air at all. For the price, I am hoping the second set I am buying holds up better. Other than that, it definitely helps with my failing tendons and increasing flat footedness. - Activemom
From the 1st time I put the Brace on it was ....{ Heaven!!!} I have flat feet and have brought a lot af Braces ,but None can come close or can compare to the comfort that I have experience from this brace Thank~Aircast*I rate this product a 10* - Pinki~Chell
They work! Designed well. For $56 I don't care if I have to replace them once or twice a year. They saved me! My feet were so painful I couldn't walk. Saved my arches and at least one of my ankles from PTTD destruction. I don't know if I purchased in time to save the other ankle. Will find out from Dr. in a few days. At size 8.5 I could have used the small or medium. The medium is a little big but easily solved by wearing an ace bandage around your foot/ankle. This also gives your swollen ankles some room. When the swelling goes down then I'll get the small. In the meantime these are great. Just pump them up! - atalanta
My doctor has been treating me for PTTD for over 2 years now. After fracturing my left ankle in April 2011, it made pttd symtoms worse. This brace has been a lifesaver as it makes it a little more comfortable to walk. I will still need surgery, but this brace really helps. - PeggyK
My doctor sold me my first brace for PTTD and this brace is a great creation and allows me to function a normal life. I could hardly walk with my swollen ankle, and the 2nd day wearing it I could do anything without pain. What a life preserver this creation is! - GaryL
Thankful in TN
Great Product! Thanks to the inventor! absolute life saver! - Thankful in TN
I was diagnosed with pttd 3 yrs ago. Very painful condition. I had the 500 dollar custom insoles made. My insurance would not cover them so the cost was out of pocket. Within 6 months they were worn out and needed to be replaced. I certainly could not fit that cost into my budget. I work at a very physically demanding job, and on my feet at the factory the entire 8 to 12 hrs every day. My foot hurt and was swollen to were i just couldnt stand that long anymore. Desperate to find some relief i came to this website. I thought for the price i will try it. I am now telling you without the brace i could no longer do my job. It has helped tremendously with the pain. Great product. Saved my job. Thanks aircast. - texasgirl
I know the aircast boot helped my PTTD for a while - aaron
I was recently diagnosed with PTTD. My physical therapist recommended this brace to my podiatrist who agreed and told me to order it. Once I found the right inflation level for me, I've been feeling pretty good! I just received one for my left foot (now I have one for each foot!) today. I ordered the two braces (same brand, same size) from two different websites. The first one I ordered (right foot), gives me some trouble with inflating (the air leaks back out as soon as I get it in. It takes some doing to get it to stay in, this has happened since the day I got it. No issues like this at all with left brace). The left one feels smaller, but I'm hoping that after a couple days of wearing will help with that. The air bladders don't seem to hit my arches in the same places either... I'll have to play with the inflation levels to see if that helps. Having trouble getting them adjusted but I'm going to keep trying. Bottom line is, I know that I'm doing better with my right foot, despite the issues I've had with the brace. I haven't been able to work in two months due to PTTD. I'm scheduled for my first four hour shift on Monday... here's hoping!! - Nikki
I've only had mine two days but despite a bad DonJoy rep at my doctor's office sending me home with one that was clearly used and didn't hold air, the replacement is helping a lot. I haven't been able to walk without crutches or a walker since my hip surgery in April but the past month has been because of my foot. In two days I'm already walking more without a crutch than I have in months. I'm definitely keeping this one! - Cindy

It works - dog lover
I've got a collapsed arch , the doctor advised me not have the operation as it was a massive op and I would be off work for a whole year recovering, he suggested I wear this ankle brace, at first I wasn't that impressed with the thought of wearing this but am glad I did. I've been wearing it now for a month and it has taken all the pain and swelling I use to have away, am really impressed with this, and if I had to buy one every couple of months I would . Excellent product . - Steve
I had pain for 8 months and finally went to MD. I found this brace myself on line once I got the diagnosis of PTTD. I must say I work everyday and per my pedometer I walk 2-5 miles a day. It has made it so much easier to function and only occasionally do I have pain at night. It was well worth the money and recommend it to anyone with this disorder. - txgirl50
I waitess so sometimes I work 8 to 10 hours at a time with no break. I have accessory navicular and have adult flat foot. I bought this brace and can now work my shift with no problems... The brace is a little wide so I had to buy new shoes but well worth it. Before I started using this brace I could barely walk. Now I walk stand with no problem... Do yourself a favor and order this brace - sn4how
I previously had custom-made orthotics. Painful! Almost as painful as the torn tendon in my ankle. This time the ankle specialist recommended this product. Pro's: it fits into my boots, I can wear it around the house in my stocking feet, it's comfortably — compared to the orthotic — and I can adjust just the amount of arch support. Con's: It's not perfect. The side supports are rigid and can hurt. I have fibromyalgia, so I wish the side supports were as soft and inflatable as the arch support. - benny2
I developed PTTD and found this brace after some online research. It is actually recommended at which presents a recovery protocol for certain PTTD conditions. The ability to "customize" the brace by the amount of arch bladder inflation and wrapping tension is the beauty of this device. While functional in terms of bracing, there are some practical trade-offs. This brace will not fit into all shoes. I wear a suit for business, and I had to find a shoe that would accommodate the added bulk of this brace while not seriously compromising the look of the footwear. The only other issue is that there seems to be a useless patch of Velcro hook material on the top of the outer aspect of the brace. This causes it to grab the trouser material. My solution to this (as well as some excess Velcro on the fastening strap) was to apply some Velcro loop material to cover it. Problem solved. - Had2

  • From luis at 2/24/2015 5:10 PM
    • Can you buy extra warranty on pttd products
    • Luis
      No I am sorry there is a six month warranty only on these braces
  • From David at 11/18/2014 7:15 PM
    • In the case of severe flatfoot on BOTH feet and posterior tibial dysfunction diagnosed on my right foot ONLY would it be okay to wear one on the left as well just to prevent pronation though not dignosed on the left foot. And would be this be okay to wear on both feet to prevent severe pronation say in place of a functional orthotic as the brace provides more stability of the ankle? It certainly feels like the brace is doing a better job of controlling the pronation!
    • David
      Yes you can wear a brace on either foot to help reduce pronation of the foot, and prevent any PTTD in the future
  • From Bill at 5/22/2014 6:02 PM
    • My Dr provided me with an Aircast PTTD brace but I want to order a spare. How can I tell what size I already have? Did not see the size on the brace itself, but perhaps I'm not looking in the right spot?
    • Thank you for your question. The size would be located on the outside of the brace. You would see it on the ridged portion under the Aircast logo.
  • From Devin at 2/17/2014 11:36 AM
    • How durable are the air pockets? What is the weight limit for the one under the arch. Im talking about various sports and weightlifting.
    • Thank you for your question. The brace can be worn during sports/athletics, as well as weight lifting. The aircell has been tested with 2,000 lbs of pressure and can withstand the addition weight of lifting and pounding.
  • From Cristabel at 1/29/2014 11:47 PM
    • I have flat feet and tend to overpronate when walking. Will this brace help keep my ankle from rolling inward so much? It's causing a lot of ankle pain which is leading to shin splint pain. Thank you!
    • Yes this brace should help with the provnation. The air bladder can be filled up to support your arch
  • From Paul at 12/11/2013 7:49 PM
    • Two questions that have already been asked have conflicting answers. Question 1 - Can it be used with sports/activities - ANSWER: Yes. Question 2 - Can it be used during rigorous workouts - ANSWER: No. I see both of these activities as t he same. I am looking to use this brace while playing sand volleyball. It would like to know if it will function while running and jumping without a shoe? Also, I have a very skinny foot and ankle, size 12 (male). Should I consider the medium? Thanks
    • Paul
      This brace is a ankle brace that also has a air bladder to lift the arch of your foot. So it is helping with ankle support and lifting the arch for those who suffer from tendonitis of the posterior tibialis tendon. Can you where it playing sports and vigorous activities, the answer to both is yes, however the air bladder may not be that comfortable. You can wear while playing sand volleyball. According to the size chart you would wear a large
  • From Terry at 11/29/2013 7:34 PM
    • my 10 year old son had the growth plate fracture on his right foot and Achilles tendinitis. It has healed, and we are looking for a brace for foot and ankle support. He is an active sports player, and we need one that will keep him from complaining about pain in his heel. Right now he is wearing shoes that range from a 7 to an 8, so we was looking for a recommendation for a brace that would give him the support he needs
    • Terry
      Thank you for contacting product support. The Aircast Airlift PTTF Brace is for those that suffer from instability of the ankle and have posterior tendon tibialis tendonitis, so this is not the currect brace for your son. We do have the Aircast Airsport that will give him good ankle support, however no cushion on the heel. We have the Aircast Airheel this brace will relieve pain in the heel but doesn't give ankle support. We do not have a brace that does both. I would suggest the Airsport and a DonJoy Silicone Heel Cup for his heel.
  • From Buck at 6/2/2013 8:59 AM
    • How long should I use this brace until my foot shows inprovement?
    • Hello Buck,

      You should use the brace as long as it is helping you and follow your Physician's Recommendation.

      Thanks for contacting Donjoy. Please call us with any additional questions. 1-888-405-3251.
  • From Katie at 12/14/2012 6:59 AM
    • Can the brace be worn during a rigorous workout?
    • Hello, Katie -

      This brace is not recommended to be worn during rigorous workouts. It is usually worn post-operatively or during the rehabilitation phase of Posterior Tibial Tendon Dysfunction.

      Thanks and have a great day!
  • From Glen Verber at 8/17/2012 12:23 PM
    • How does this fit in a shoe, or under a sock.

    • Hi Glen

      First, I would suggest you put on a sock then put the brace on over your sock. After the brace is on, you will have to loosen your shoelaces and place your foot in the shoe. Lace up your shoes and you are good to go.

      If you feel like you need a more low profile ankle brace, we carry a variety of braces. You can contact us at 1-888-405-3251 to consult with a product specialist to see what best fits your needs.

  • From Oberman at 3/24/2012 11:10 AM
    • how much do I have to inflate the pttd brace?
      Thanh you
    • Inflation amount is based off of comfort and pain relief level. It will be different for everyone.

  • From Lee at 6/7/2011 11:58 AM
    • I actually have very high arches, but am having bilateral PTTD. Do you think this product would help even though I don't have "flat feet".
    • Yes this brace with the adjustable aircell will help with your PTTD issues.
  • From Sarah Watson at 6/4/2011 6:07 AM
    • Should top strap go right around the back again after going round the front? I have a small and medium size..the small one's top strap goes around once and the outside support seems to slip forward a bit when walking. The foot bit is tight...but this one sits inside my trainers much better than the medium size which is quite bulky and I can feel the bottom of the supports around the back of my ankles. With the medium one the top strap goes aroundto the back again at the end and holds the outside support in place.I am UK size 7.
    • The uprights should sit on the inside and outside of your ankle and yes the strap should wrap around the lower leg for you. Should you have any other questions please let us know.
  • From Kelly at 5/27/2011 7:02 PM
    • My doctors office told me I could wear the aircast brace in a shoe, but it is much more comfortable wearing it by itself. Is this okay or should i be wearing a shoe over it?
    • Hi Kelly,
      When you are walking around the house a shoe is not necessary but when you leave the house you will need the added support of a shoe. I recommend using sneakers or Tennis shoes and redoing the laces while you are wearing the anjkle brace. it should be much more comfortable.

  • From Faith at 6/8/2010 1:52 PM
    • Should I wear my regular orthodic in my shoe while wearing this brace? Thanks so much.
    • The Aircast PTTD will support the arch and with an orthotic may be too much support. Best to see how it feels and ask your doctor.
  • From Rich at 3/26/2010 10:41 AM
    • Can I use this brace for sports?
    • Yes, the Airlft PTTD can be used for a variety of sports and activities. We suggest walking first to get used to it a bit before doing any heavy activity. This will help your foot get used to the extra support.
