Anatomical Design Helps Realign & Support The Ankle

The AirLift PTTD Brace is designed to provide support for 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 used 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. We recommended wearing this brace with an athletic or walking shoe as the brace may be slightly bulky.

Product Features...and the benefits you'll experience!

Aircell Technology
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.
Easy To Apply
Just slide your foot in and secure the two straps.
Adjustable Inflation
The aircell inflation can be adjusted while the brace is on the foot in order to achieve the perfect comfort level.


Hand wash with mild detergent, rinse with tap water and air dry

    • I was diagnosed with PTTD 5 weeks ago. Ran a marathon 3 weeks ago. Bad idea. Have not run since then. Have a half coming up in four weeks and am wondering if this will help the discomfort. Thank you
    • The Airlift PTTD Brace is desinged to put pressure in the arch of the foot and help stabilize the ankle joint. This brace will help with your pain, but its important not to overinflate the aircell if you are planning on using it for running. And you will want to make sure to test the brace on smaller runs first.
  • David Montero at 9/22/2016 1:53 PM
    • Does this brace support the arch and the planar. This seems to be a little better than the aircast airheel
    • The Aircast Airlift PTTD Brace is designed for Posterior Tibial Tendon Dysfunction and flat foot. The Airheel does offer more support for Plantar Fasciitis.
  • monica at 9/21/2016 12:56 PM
    • Hi there! Our son is 8yrs old and plays AAU basketball. He's been complaining about his ankles a lot - we've also noticed that his feet seem to be flat and his ankles roll inward a bit. We haven't taken him to specialist yet..but will obviously do so if the problem persists. In the meantime, we wanted to try an ankle brace that offers arch support to try and help with the flat foot/ankle rolling issue...would this brace be a good match? It looks a bit heavy and bulky so not sure if it would fit into his basketball sneakers (usually Under Armour Curry HighTops)- is this something that can actually be worn while playing? His foot is a size 4.5/5 Youth/Mens..so he'd be a size small. If not, do you have another recommendation? Any feedback is much appreciated! Thanks so much!
    • The Aircast Airlift PTTD Brace is designed for Adult Acquired Flat Foot Syndrome, and may not be the best brace to prevent rollovers. You may want to consider the Stabilizing Speed Pro, https://www.betterbraces.com/donjoy-stabilizing-speed-pro-ankle-brace, which is quick and easy to use, fits well in athletic shoes, and is available in smaller sizes.
  • Cindy at 9/12/2016 2:47 AM
    • I have PTTD and my doctor gave me a "medium" Aircast Airlift Brace. However I wear a size 8 shoe and according to your size chart a "small" is the appropriate size? My ankles are rather wide- approx. 9 inches (measured all the way around) and I wonder if a "small" would still fit properly? It seems the medium I now use is a bit too large and I had to buy a size 10 shoe to accommodate the cast.
    • We would recommend the Small
  • Marley at 8/14/2016 9:16 PM
    • I'm 13 and I have PTTD and I do lots of sports would this brace be good for that?
    • Yes, the Aircast Airlift PTTD Brace can be used for non contact sports, to support PTTD.
  • Cindy at 8/10/2016 12:10 AM
    • How do you clean this brace, especially odors?
    • Please hand wash the Aircast Airlift PTTD Brace with detergent and let it air dry.
  • Michelle at 8/4/2016 5:13 AM
    • This product is extremely bulky. I'd have to buy wide shoes just to accommodate it and it has been helpful. Please, please, please make a newer model that is maybe like a sock or sleeve with the air cell or something.
    • Depending on what you are using the brace for, you could take a look at the Donjoy Trizone Ankle Support- It is very thin and fits inside the majority of shoes.
  • A.M. at 7/1/2016 5:31 PM
    • I recently went to my orthopedist for Plantar faciitis but she also found through xrays that I have extremely flat left foot. They gave me a Aircast brace without the pump. Not a problem since flat feet is associated with plantar faciitis...but I think its too large. I am a woman who wears a size 8 shoe and according to your chart I should have a small. They gave me a medium and its roomy. Even with a thick sock. In addition I recently had leg vein blocked and or removed and that area is still sensitive. Also plantar is very painful. Will the brace cause more problems than I already have because it's too big? I'm not to go back for another 3 weeks. Thank you.
    • Based on your diagnosis we would go with our AIRCAST AIRHEEL ARCH & HEEL SUPPORT. This a soft brace, which would not cause any sort of discomfort to your foot, its also very low profile to help fit into any shoe and very easy use. The AirHeel™ brace is equipped with two interconnected aircells located under the foot arch and in back of the achilles tendon. When you take a step, the first air chamber (under the arch) begins to collapse thus reducing the stress to the plantar fascia under the arch. Air is forced into the chamber surrounding the achilles tendon which then inflates. The inflated achilles chamber applies compression to the achilles tendon to shorten the lever arm thus reducing strain on the tendon.

  • Debra at 5/8/2016 3:45 PM
    • I have the aircast brace with the air cell under the arch. I have lost the little pump that came with it. Do you have extras for sale?
    • You can order the pump by calling DJO Direct at 800-336-6569
  • Mike at 4/21/2016 2:51 AM
    • I am a large man and I wear a size 13 wide shoe. I was wondering if the brace will be big enough? I weigh about 415lbs thanks
    • This brace is sized based on shoe size but the calf strap is what the problem is going to be. The calf strap is standard size and will fit a calf circumference of up to 10"
  • Vahid at 4/7/2016 7:25 PM
    • Please advise about the foot size measurement for teenage with flat feet to choose the right size of this brace.
    • The brace is sized by shoe size. Please refer to the sizing chart for sizing information
  • Elizabeth at 3/25/2016 11:43 PM
    • Are there limitations to ankle size for getting a good fit? My shoe size indicates a medium brace, but do I need a large brace to accomodate my large lower calves/ankle (11.5")?
    • Since the brace is based on shoe size the strap at the top of the brace will be the same length regardless of the size brace. The strap is about 18.75" long
  • Lee at 2/14/2016 8:56 PM
    • Can I wear this brace with my orthotics? I only have pttd with the left foot but I am wearing orthotics in both shoes.
    • If your orthotics give you a arch then you may not need the brace. Using both will be a lot in the shoes
  • Pat at 2/6/2016 9:43 AM
    • I bought a pair of these and they work well. However while playing football, I broke off one of the bladder nipples. Is it possible to only get a replacement bladder? I've only had them for a month.
    • We do not have replacement parts for this brace but they do have a 6 month warranty so you may be able to get a replacement
  • Todd at 1/18/2016 10:25 PM
    • I've had pttd now for 6 months and been using a walking boot to stabilize my foot until I could afford an ortho brace and the I came across this air cast brace that looks great , will this brace treat my pttd the same as the ortho brace my doctor wants to prescribe me ?
    • The airCast Air Lift PTTD Brace will help by lifting up the arch and taking pressure off of that tendon. This process should decrease pain in the ankle and foot. You can try the brace, we do have a 60 day money back guarentee on our return policy
  • Debbie at 12/30/2015 6:04 PM
    • I need a replacement to wear I the next 3 weeks and misplaced th original brace I got in September. Please note that I am recovering from surgery and am stepping down from a boot back to this brace. I was originally told to get a medium but I am a size 7, which according to the sizing chart I am a small. Will the medium be extra big for me? Please advise.
    • According to your shoe size you should be able to fit into a small unless you have an unusually wide foot then maybe a medium might be better
  • Caitlin at 11/11/2015 6:48 AM
    • I understand this helps with flat foot and rolling the ankle inward, but does it support from rolling the ankle outward as well?
    • Caitlin
      This brace is essentially a ankle brace that will prevent the ankle from turning inward and outward as well as lifting the arch of the foot.
  • Dave at 10/22/2015 6:54 AM
    • I have had a few of these braces and they are great. Only problem is the valve to pump air in always breaks. I am told to send entire brace back but this leaves me with no brace for some time. Is there any way to just get the tiny valve? Makes more sense than getting whole new brace. Thanks
    • Dave
      I am sorry but we do not have replacement valves for the brace. If the brace is under warranty and the brace has to be sent back, you can wait until the new one arrives before sending the defective one back
  • Katelyn at 10/19/2015 7:31 PM
    • How well does it fir in a shoe? It looks like it is too wide. Can it fit in sport shoes well?
    • It will fit into a tennis shoe
  • Marcie at 10/14/2015 10:05 PM
    • I wear a as 9 women's shoe. With it being the smallest size on the medium sized brace would it be better to go with a small? Don't want it to be too big. Thanks for your help
    • Marcie
      The medium is the size you need it will not be too big
  • julie at 10/13/2015 8:37 PM
    • can i purchase a replacement aircell since mine has a leak?
    • Julie
      We do not have replacements for that brace. The brace has a 6 month warranty so if it is still in warranty you can get it replaced by contacting the place you purchased.
  • Bella at 9/10/2015 10:46 AM
    • Can I drive my car while wearing this brace?
    • Bella
      Yes you will not have any limitations wearing this brace
  • Tracie at 9/9/2015 12:06 PM
    • Can you wear this brace without socks? My current brace I can only wear for a few hours at a time because it digs into me, maily in the heel area. Does thia brace have that issue as well?
    • Tracie
      You can wear the brace without socks however most braces are meant to be worn over socks to prevent any rubbing.
  • Kevin at 8/24/2015 4:08 PM
    • I'm an avid runner and have a very active job. My PTTD is mild but very chronic, been dealing with it for two years. Is there any feedback from anyone who wears the brace during running? Can it be used during activity or would it be a better tool for recovery?
    • Hello,

      Thank you for contacting Betterbraces. The PTTD brace has 2 very rigid uprights built into the brace. If you have ever worn a Air-stirrup they are similiar in the amount of rigidness. The Aircell in the arch is designed to take a very large load of impact, so you can run in it. I'm confident you would enjoy this brace for a job setting, but not sure if this brace may be a little too rigid for the amount of running you do.

      Have a Great Day.
  • Keneisha at 8/17/2015 9:09 AM
    • This brace does provide ankle support for the fracture but also provides arch support
  • Christine at 8/5/2015 6:37 PM
    • I just tried on my brace. I don't have very high socks on, and the velcro on the top strap rubs against my skin in the back. Do I have it on wrong, or do I just need to wear higher socks?
    • You will need to wear higher socks
  • fred at 6/16/2015 5:58 AM
    • Can i buy the small plastic tip where the air pump goes. I've gone thru 4 casts due to broken tips.
    • I am very sorry, but the valves are not sold separately.
  • Judy at 5/29/2015 6:19 AM
    • This brace sounds like it may be just the thing for me. Does it come in any color other than black? Looking for a nude or beige one.
    • Judy
      No only comes in black

    • Hello my big 5 year old son walks on the inside of feet, his left foot is way worst that right. Would this brace work for him? He is extremely big for his age, weighs 65lbs.
    • Kristin
      The Aircast Airlift PTTD Brace, has a air bladder in the arch of the foot so that when inflated will lift the arch up. The brace is mostly for flat feet. It is possible that it could help your son however the smallest size the brace comes in is a small which fits mens shoes size up 7
  • Jean Madden at 4/23/2015 9:22 AM
    • I have lost my bulb to pump my brace up, is it possible to purchase a new bulb?
      Thank you!!
    • Jean
      you will need to purchase the bulb from DJO Direct at 800-336-6569. The part number for the Bulb is 02P100
  • 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
  • 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.
  • 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.
  • 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
  • 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
  • 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 https://www.betterbraces.com/aircast-airsport-ankle-brace that will give him good ankle support, however no cushion on the heel. We have the Aircast Airheel https://www.betterbraces.com/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.
  • 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.
  • 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!
  • 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.

  • 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.

  • 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.
  • 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.
  • 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.

  • 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.
  • 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.

    Great Product

    Reviewed by:
    Five years ago I broke my tendon and I need operation. The orthopedic would not guarantee it. And he is the BEST. I so appreciate his honesty. He recommended this brace until I decide if I was going to do the operation. My mother had Alzheimer so I could not do it. Five years later, I am still undecided, but I could not walk without this brace. I only wish you could think of a wedding that women could wear shoes with this brace.... please. I have been 5 years with sneakers on. :0((((((((
    Pros: Wonderful brace. Great support. Could not walk without it.
    Cons: I am a women. I want to wear pretty shoes.... HELP
