Product Details

Product Description

Acknowledged by the medical community for its superior performance in helping to heal ankle injuries.

The Aircast Air-Stirrup ankle brace is commonly worn immediately after injuring your ankle and throughout recovery because it helps accelerate rehabilitation. Since 1978, the Aircast Air-Stirrup Ankle Brace has been the brace the medical community has turned to for the functional management of ankle injuries. Functional management means wearing the brace enables you to continue your daily activities while recovering from your injury. The Aircast Air-Stirrup has been cited in over 100 medical journals for its superior performance in helping to heal ankle injuries.

It is the patented Duplex™ air cell system that makes the Air-Stirrup so successful at treating severe ankle injuries like third degree ankle sprains. This exclusive system incorporates two pre-inflated overlapping air cells (distal and proximal), that provide support and produce graduated compression when walking around. The compression helps reduce edema, the swelling that is caused by fluid trapped in your body's tissues, as well helping to accelerate rehabilitation.

The Air-Stirrup Ankle Brace is used to treat or prevent the following injuries:

  • Acute injuries of the ankle
  • Third Degree Ankle Sprains
  • Severe Chronic Instability

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

  • Semi-Rigid Shells
    Provides support and protection from inversion and eversion.
  • Anatomically Design
    Ensures you'll get a comfortable fit.
  • Pre-Inflated Aircells
    The brace is ready to wear...all you have to do is strap it on.
  • Streamlined Fit
    Easy to fit in your shoe when it comes time for early protected weight-bearing movement.

    • I had a question i had surgery on my ankle four weeks ago. My shoe size is 7 1/2 in ladies i am not sure if i should get a small brace or medium. please let me know thanks
    • Thank you for your question. The small Air Stirrup is 6" in height and the Medium is 8.75" in height. Height is measured from the base of the outer shell to the top. Generally the small is used for pediatrics most likely the medium would be sufficient.

    • I shattered my tibia and fibula and many years ago and have plates and pins holding it all together. I have re-injured it more than once. I was told after the last injury that I should be wearing an Aircast brace everyday. My question is I'm a plus size woman (large calves) who wears size 9 shoes but I'm only 5'6" would you recommend the large size? From the way I read the measurements it seems to be based more on height. Help! Also does this sound like it would be the right brace for this type of injury/need? There are a lot to chose from. :)
    • Corinne
      The Aircast AirStirrup akle Braces are sized based on the hieght of the brace. So you would measure from you r heel up to the lower third of your tibia. The brace should sit just below the belly of your calf muscle. I would suggest the aircast Airsport ankle brace for everyday use. It goes by shoe size and fits better into a shoe than the Airstirrup. Take a look at this one;
  • celeste coar at 16/12/2013 5:00 am
    • Would the Aircast air stirrup ankle brace restrict mobility of the ankle
      so it could be worn at night as well as while swimming? I have a
      sprained ankle and am in a walking boot in the daytime. Or do you
      have something less cumbersome than to sleep in than a boot (the xcel trax air)

    • Celeste
      You can wear it to bed if you like. Thank you for contacting DJO

    • I have a sev 3 sprain. Doc's prescription said to get a Medium Aircast Ankle Brace. The medical supply store only has size Large (Air-Stirrup ankle brace). My foot is size 11, but I have pretty slim ankles and lower leg. Is Large ok, or should I get a Medium do you think?
    • John
      The Aircast air-stirrup ankle Brace is sized by the hieght of the brace going up your leg, not shoe size. The medium is standard size and has a height of 9", the large is 10.5". The large should be fine on your leg. If you have anymore questions please do not hesitate to ask. Thank you for contacting product support.

    • I'm an old guy 72. My left ankle was infected with a staff infection a year ago.
      It is bone on bone now. The surgeon said a ankle fusion would help with the pain.
      I would rather not do that. Would an ankle brace help? If so which one would you recommend? I weigh 220. 6-3" My toll free phone is 1-888-795 1232
    • Hello Terry,

      Take a look at the Airsport Ankle Brace, this brace has a medial and lateral rigid support. Used for moderate support. The A60 also has rigid support but more streamlined, for Mild Support.

      Thanks for Contacting Donjoy.
  • Melodie at 30/06/2013 1:07 pm
    • After wearing the aircast for a day, the air seems to have pressed out. I've read the warnings about how too much air will make the cast cease to support the ankle. How much air is too much?

      How often is appropriate to refill it with air?

      And is blowing in the "straw" sufficient to fill it?

      Thank you.
    • Hello Melodie,

      After re-inflating the air cell be sure to fold over the tip of the air cell and secure it. You shouldn't need to refill air cell, too much air will not allow the air cell to mold around your ankle. The brace should be comfortable around your ankle.

      Thanks for contacting Donjoy.
  • Dan at 5/06/2013 9:52 pm
    • I already have an air cast but it is marked left & I just rolled my right ankle. Can I just flip it around & use on my right ankle?
      Thank You
    • Hello Dan,

      I believe you could try and do that, if for some reason you feel like its not comfortable, you could purchase online. Below find the link.


      Have a Great Day.

    • Our doctor has recommended the Aircast Air Stirrup Ankle Brace for my 10-year old to wear while recovering from a sprained/strained tendon in her left ankle. She is 4'11" tall. What size do you recommend? Thank you.
    • Hello,

      Sizing is determined by the length needed for the brace. I believe a small will work, the width of the brace is adjustable, you can change that at any time. The length of a Small will be 8.7 inch's.

      Description Brace Length
      Pediatric (XS) Ankle Brace 6.0" (15 cm)
      Small Ankle Brace 8.7" (22 cm)
      Training (Medium) Ankle Brace 9.0" (23 cm)
      Standard (Large) Ankle Brace 10.5" (27 cm)

      Please call us with any additional questions. 1-888-405-3251.
  • Stephanie at 31/05/2013 11:12 am
    • When adding or removing air to the chambers, the "goop" that is in the valves gets pushed down into the air cell - do I need to worry about the cell not holding air once this happens? (had to release some air during high altitude travel and had to add air once back at sea level)

    • Hello Stephanie,

      How long have you had the Brace? You have a 6 month warranty. You shouldn't have a problem with adjusting the amount of air in the air cell. If it's past your warranty, we do have replacement aircells you may purchase.

      Have a Great Day.
  • kiki at 29/05/2013 5:33 am
    • Should I wear this while I am icing my sprained ankle, or should I remove it?
    • Hello Kiki,

      Please contact your Physician regarding any restrictions they may have placed for you. Typically when you apply cold therapy to an ankle sprain you do so without any bracing, place a thin barrier between your skin and the ice. Again, contact your Physician with further questions.

      Have a Great Day.
  • William Roy at 12/05/2013 3:21 am
    • The strap (under the foot connecting the two side slats) on my air-stirrup ankle brace tore after just a few months use. All other pieces are still in good. Is there any way to get just a replacement strap?
    • Hello, William -

      Please give our customer service representatives a call at 800-336-6569 and they can assist you in getting that strap replaced. Depending on how long you've had the product, it still may be under the warranty so the straps can be replaced if that's the case.

      Thank you and have a wonderful day!
  • Zakaria at 8/02/2013 12:55 am
    • Hello,

      i have an ankle that is very weak, ie, it rolls over VERY quickly and it hurts .. I need a good ankle brace that blocks inversion movement almost completely yet still allows me to play soccer with it on a regular basis..

      Also, what are shipping costs to Belgium?

      Thank you very much

    • Hi Zakaria,
      A good option for your ankle to give it plenty of support while still getting out and playing soccer would be the Aircast Airsport Ankle Brace. Unfortunetly, at this time, BetterBraces does not ship outside the U.S.
      Here is the link from BetterBraces to get a visual of this brace. https://www.betterbraces.com.au/aircast-airsport-ankle-brace

      Thank you and have a great day!
  • susan at 12/08/2012 11:13 am
    • I received an aircast stirrup ankle brace while in the emergency room, but did not receive any instructions. Should I wear the brace while sleeping or in the shower? Or does my ankle need a rest from it a few hours a day?
    • You should wear it whenever your physicians has told you to wear it. I am not sure of your condition so I cannot comment on that. You can get the Air Stirrup wet, you should rinse it and allow it to air dry.
  • Kathy at 3/08/2012 4:14 am
    • After being in a hard cast for 4 weeks, ( fractured fibula) I was given this air cast air stirrup ankle brace. So my question is, Can I wear the brace while in a pool? Or will it damage? Thank you
    • You should rinse it in tap water afterwards and allow it to air dry.
  • Doreen at 20/06/2012 9:35 pm
    • Can you swim with the aircast?
    • Yes you can swinm in this, just rinse it with tap water after.
  • Peggi at 6/06/2012 12:01 am
    • I wear a ladies 8-1/2 shoe. What size brace would be appropriate for me?

    • The Aircast air stirrup is based on the height of the brace, which is shown on the page. The shoe size doesn't matter.
  • winnie at 1/06/2012 3:34 am
    • a women's size 9 would be an air cast small or medium?
    • Medium
  • John at 24/05/2012 5:00 am
    • I wear a size 9 mens. I have a problem with my ankle rolling when hiking. This has resulted in a ankle injury. What size of aircast stirrup would you suggest for me. (my legs are slim)
    • If you are planning on hiking or being active, I would recommend the donjoy Velocity ankle brace. The Aircast Air-Stirrup is for post injury for everyday activities, inwhich case you could go with a medium.
  • Katie at 9/01/2012 9:51 am
    • I have a VERY old aircast ankle brace which I shortened by cutting the top 1-2" so that it is 8" from bottom to top of brace. But I'd like to update it. My foot size is women's 11. Would the Small still work for me (since I'd prefer the shortest possible height).
    • Hi Katie,

      Yes, the small would work for you. It is just over 8 inches tall.

      If you have additional questions, please call 1-800-553-6019

      Have a nice day.
  • Ashlen at 14/12/2011 9:13 am
    • If I already had a cast on and am just getting my cast off after having a broken fibula (No surgery was needed) and am looking for something to help me get back to walking okay, and that I can use whenever I feel the need to while running, excercising, etc. is the Air-Stirrup Ankle Brace the best option or would the Air-Sport Stirrup Ankle Brace be a better option (i'm liking how it states it is narrow for daily shoe fitting.)
    • The Airsport is a better choice to wear during activity and exercising, it provides more joint stability and fits in a shoe better.
  • Rick Gleitman at 8/10/2011 3:51 pm
    • 1) If my shoe size is a Mens 10 1/2", which size Aircast Air-Stirrup Ankle Brace would I order?
      2) Does Aircast still make the "Aircast Sport Stirrup Lateral Side?
      Please let me know the answers to the above two questions and which model I should order.

      Thank you,

    • Depending upon the injury and if you are wanting to be functional with the brace on, will vary for each brace. For post injury the Air-Stirrup brace, being a Men's size 10 1/2" the Medium will be a good size.
      For functional you may look at the A60 (will closest equivelant to the stirrup lateral side)
      Please let us know if you have more questions.

    Support, reduced swelling, less pain when walking

    Reviewed by:
    Verified Purchase
    Recommended by physio treating my bilateral chronic ankle sprain. Repeat taping was irritating skin and didn't provide enough support. Brilliant result as I was virtually pain free, swelling came down and I could walk comfortably. Had to wear with lace up shoes but needed to do that anyway for stability. Ice and elevation still necessary. Eventually needed ligament repair surgery and the surgeon used the splints post-op for stability and swelling.
    Pros: No skin irritation (wear thin long socks underneath) Natural walking Helped reduce swelling Can maintain lots of normal activity and exercise
    Cons: Wear and tear on sides of shoes from hard sides Not suitable for regular shoes for work or dress

    Excellent aid to recovery and mobility

    Reviewed by:
    I suffered years of chronic ankle instability after repeated sports injuries. A physio suggested the air cast after a sprain and I was amazed at how effectively it reduced swelling and provided stability that enabled me to keep working and doing usual activities, although sport was curtailed while healing. I wore with flat closed in shoes, mainly runners, as the rigid sides caused wear and tear on the edges of my shoes and I didn't want to damage dressier shoes. I bought both left and right as I had trouble with both ankles. Have since had surgical ligament repair of both ankles, and the surgeon recommended air cast for 8 weeks to assist rehab. The casts helped minimise swelling, prevent inversion and support mobilisation while recovering. After wearing continually the velcro and adhesive became weaker and the air cells came off, requiring double sided tape to reattach - that's the only reason I'm rating 4 instead of 5.

    My doctor suggested I use this when I sprained my ankle three weeks ago. It's very comfortable and allowed me to just use one crutch instead of two.

    Made my ankle feel much better

    Reviewed by:
    I sprained my ankle during a tennis game and my doctor recommended this airstirrup. There is something about the aircells in this brace that made my ankle feel loads better when I was moving around. Wearing this brace and a whole lot of ice really helped me feel better.
