Aircast FP Walking Brace reviews

I wore this after I fractured my foot and it was a total life saver. Really surprisingly comfortable. A lot better than being stuck in cast. I now wear and Aircast Ankle brace that I really like too. Nice products! - BethAnn
First of all, let me say that I am a *very* picky girl. I severely sprained my ankle a couple of summers ago. I couldn't even walk, but an x-ray revealed there was no break. My doctor advised that immobilization was necessary, so I went to the local pharmacy and picked up the brand of "walking boot" they had in stock. MAN, was that thing HEAVY. The weight of the boot on my foot/leg while walking was horribly uncomfortable for my weak ankle. In addition, the walking boot didn't immobilize me even as well as my ankle brace did when wearing a shoe. As soon as I tried it on, I knew that it was NOT what I wanted to be wearing for weeks on end! I started looking online -- researching and comparing all the available models of walking casts. I ended up getting the Aircast FP Walking Brace. I first tried the Aircast SP Walking Brace (the shorter model) but found that the taller version immobilized my ankle much better. The inflatable inserts feel like heaven to someone with an ankle injury -- compressing the injured area to reduce swelling and slightly massaging your ankle while you walk. You are able to inflate/deflate each side independently for a customized fit. Some other walking boots I tried had only foam across the top. They were basically a foam boot, attached with straps to a hard rubber-type lower/vertical shell. When I walked in one of those types of boots, it felt like my foot/leg was pulling up out of the boot, and while my foot was in the air during a step, the weight of the boot hung off my injured limb by the velcro straps. Ugh, so painful! Not so with this boot! The semi-rigid outer shell is held comfortably in place by the adjustable straps, providing a firm, stabilizing hold. Unlike other boots I tried, it never feels like this boot is hanging like a weight. I don't know if this boot is actually lighter than other brands of walking boots or if the construction just provides better pressure and weight distribution, but it certainly feels much lighter and more comfortable while walking. This walking boot was exactly what I had been looking for. Yay! No more crutches + ankle brace! Because I am also a very clean girl, I appreciate the fact that the liner and insole can be completely removed and washed. You can also purchase replacement liner and insole sets separately, and the shell is nearly indestructible. I went out playing in the woods and on the beach in this boot, and can attest to how wonderfully it cleans up! I don't often write product reviews, and for anyone without lower limb pain, I can see that this review might seem a bit too enthusiastic. But if you're facing having to wear one of these things for weeks or months yourself, you might better be able to appreciate how these features can make your recovery more bearable. Happy healing, everyone! :) - Jenna
Because I'm self employed and can't afford the post op recovery time off, have decided to just wear this Aircast boot. Fit is great and a pleasure to wear. - Steven
After a severe ankle sprain I was given a splint at the hospital and purchased some crutches. The splint offered very little support and the crutches made it impossible to do anything. Fortunately the orthopedic doctor I saw for follow up the following week put me in this aircast boot. What a difference! I could move around when I had to without pain because of the support it gives. The interior airbags allow you to adjust the support level as the swelling of the foot changes, or as needed for comfort. A bit more for walking and a bit less for when relaxing with your foot up. Unless you have someone who can wait on you hand and foot (no pun intended!) get one of these....I HIGHLY recommend the Aircast boot! - Casey
Major help with walking when I had a severe foot injury. - TX
I was first diagnosed with extensor tendonitis but I never seemed to get better. I called the doctor's office and asked if I could wear a walking boot. They said that was OK so I bought a boot at the local medical supply office. it seemed to help somewhat but was also very hard to wear and I finally gave up wearing it. I decided to get a second opinion and was diagnosed with a stress fracture. I understand it can sometimes be very difficult to diagnose with an x-ray, but this doctor was almost certain it was a stress fracture with just the examination. X-ray confirmed the diagnosis. He put me in an Aircast FP walker which is much more comfortable than my previous boot. Even though it is larger it is more comfortable. I wear it all day and then take it off to sleep at night. My previous boot did not have the inflatable air cells and I found it impossible to make it fit correctly. I'm very happy to have a correct diagnosis and a correct comfortable treatment. - Nancy
I received this brace when it was discovered that I have a rather large stress fracture on the heel of my foot. Needless to say it was quite painful to move much less walk on my foot. The brace helps to stabilize the heel and the air cushion is great, it is like walking on air. My shepherd dog however thought that the inflate/deflate pressure guage would make a great "chewie" so that will have to be replaced. It is somewhat awkward to walk with but is alot better than being in a hard immovable cast. One other note - due to the height of the heel on the brace I find that I have to wear a shoe on the other foot with a higher heel to keep me level. So for the next 6+ weeks this will be my constant companion. - hubcap
A year ago I suffered 3 hairline fractures on my left foot. Now I've been advised that I have a stress fracture on my right foot. I almost got rid of the boot never thinking I would need it again almost a year to the day later. As the boot fits either left or right, I don't have to buy another one. Although I hate the damn thing this is some consolation as I will be wearing it for the next 3 to 4 months again. Hopefully this is not an annual event. - Kate
In South Africa these braces are called Moonboots, for some obscure reason, and I have had one for over seven years. The model I have is the Foamwalker, and it was first prescribed for a foot injury in 2005. It has sinced done the rounds of friends and family, and myself again when I suffered another injury. Recently I slipped on litter in the street and landed up in the boot again. The doctor wanted to prescribe a new one, but I told him there was no need, I had one already.If he'd known the vitnage, he would probably insisted, but it's still alive and well, and on my ankle as I write this. My husband is, sadly enough, also in the latest version of the boot at this time, and his comment is that the cleaner lines of the older model are less uncomfortable when they come in contact with the rest of the body, and there I do agree. The fancy new shaping gives edges for other parts of the body to catch on, and that is the only down side to a very good product. My boot has done many miles with me, and I am very happy with the long aircells. They are a lot more comfortable than the pneumatic walker, even though one would expect the pneumatic walker to have more support. It's the height of the cells at the ankle which makes the difference. I hope this helps somebody out there. We would have been happy to know these facts before ourselves - Wol
Have a broken 5th metatarsal. This boot stabilized my foot and reduced the pain a lot. Being able to remove it for showers is a huge bonus! - me
I have been in the Aircast FP boot for 6 months. 1st orthopod said "old age" and tendon tear until I went back 3 months later and MRI showed ruptured posterior tibial tendon. 2nd orthopod specializing in foot injuries recommends surgery "when you are ready" so will wear the boot until surgery. Use 20 to 40 pound dog food bags to cover boot when I use the rototiller, work in the garden, wash the vehicles, feed/clean the chickens, mow/trim the yard, etc. This boot really shows the wear and tear that I am putting it through and will order a new one for "dress and special occasions" and the older one for daily wear. Going without the boot is not an option --- the pain and swelling are too much for me. My husband is wheelchair bound, we are both retired, we live in the country with limited income and limited family assistance so being off my foot for 8 weeks post-op is not an option at this time.. I thank God for the boot design and the tough outer shell that keeps me relatively pain free since I am up and moving early each day. The "air bags" even allow me to drive the vehicles where I need to go with minimal discomfort from the vibrations. A MIRACLE!!!! - Me
I am going into 9th grade. My 7th grade track season didnt start off great. I have had two stress fractures, RSD, and osteopenia in the past year. They put me in a black camwalker at first. It was very heavy, and the bottom wore out very quickly. That fall when they discovered the second stress fracture I was put in a cats for six weeks. I then recommended to my doctor instead of buying a new black camwalker to get me this. I was still on crutches when I got it. This is a lot easier to use than the black camwalker. I walk better in it and it fits my foot better. I am still currently in this camwalker and love it. I would highly recommend this boot! - Alyssa

I recently broke my foot and was provided a walking cast of sorts from the ER but was unhappy with the weight and feel of it. After much research, I found and am I glad! I ordered the Aircast FP Walking Brace yesterday and received it this morning. What a huge difference! The comfort and feel is very good! Much better than the brace I was provided by the hospital. I'm hoping I won't need another visit to the ER anytime soon for a broken bone but if I am, I will visit this site and see what they have to offer. I'm sure it'll be much better than what a hospital or doctor's office will provide. I also feel that the cost was very good. You can't put a pricetag on comfort. - Rich - Omaha
I have second and third metatarsal fractures. Originally they gave me a splint. The orthopedist switched me to this boot, it has been very painful, I have no idea how much is too much or too little pressure, either the place of fracture hurts or the rest of the leg. The first night wearing it was very painful. - Lou
5 weeks ago, I underwent 1 MTP w/Arthrodesis surgery for a severly arthritic large toe. After 4 weeks in a hard cast and on crutches I went back to the surgeon and said either cut it off or I would. I was destroying my shoulders (I AM 66). He put me in an AirCast Walking boot but admonished putting much weight on the font part of my foot. This boot has been a godsend. My only question is, how did George Lucas convince all of those extras to wear them as Storm Trooper Boots in Star Wars? - Tim
This boot is a life saver! About a month ago I had a bad fall and severely injured my ankle and leg. I fractured both my tibia and fibula in 2 and 4 places respectively. After weeks in a cast, they moved me to this walking boot. The support was just as good as my cast, but the positioning made me feel confident as I started to be able to bear weight! Unfortunately I still have a rod in my leg that will come out in a few weeks. I love the custom air pocket support in this cast. If there is pressure on the right side of my ankle where the rod is, it hurts big time! But this allows me to get the support I need in the way I need it for my specific injury. A lot of the time I pump up the left side 100% and the right side 20% and I still get full support! I'm getting more mobile every day and I couldn't be happier with this product :) Thank you! - tara

    • What is the difference between the XP Walker and the FP Walking boot?

    • I have the FP walker and one of the inflatable cells has come loose and won't stay in place... any ideas?
    • Kelli, typically the AirCast FP Walker Aircell can stay in place with use of double sided tape. If you apply that tape between the aircell and the shell of the walker, that should keep it in place. Should you have any additional questions please do not hesitate to contact us at again.
  • From Sam at 5/31/2011 4:56 PM
    • Is this kind of brace good for plantar fasciitis

  • From Brian at 8/10/2011 2:36 PM
    • How much do I inflate this, i.e., how tight should it be?
    • When inflating, you want the boot to feel snug, but not so tight it is cutting off circulation. Start with 2-3 pumps in each cell, and then add one pump to each till it feels snug.

    • Should l wear my FP walker to bed?
    • Hi Richard,

      Wearing the walker to bed or not would be determined by your injury and your physician's treatment protocol. I suggest checking with him/her to see when it is appropriate to take the brace on and off.

      If you have additional product questions, please call 1-888-405-3251.

      Have a nice day.
  • From Michael at 3/25/2012 10:09 AM
    • Can one take a shower with the FP on?
    • The FP walking brace can get wet. But, the sole is not designed to be 100% slip resistant and may not be safe to wear while showering. I suggest checking with your physician and ask if it is appropriate for your injury to take the walking brace off while showering or if you need to follow other bathing procedures.

  • From Bob Schowe at 5/23/2012 8:01 AM

    • Hello Niamh,

      Deflate the Aircells, they may be overinflated and pushing your shin forward in the boot. Try deflating them and they inflate to comfort.

      Thanks for Contacting Donjoy.

      Thanks for Contacting Donjoy.
  • From Kitzia at 8/4/2013 7:56 AM
    • hello,
      I just started to wear the FP walking brace due to a sprain on of foot ligaments. I have been using the boot to walk however, whenever I do I feel pain on the front of my leg. Is this normal? I have tried inflating and deflating the air cells to adjust the comfort but that really hasn't made a difference.
    • Hello Kitzia,

      Please refer to your Physician regarding the pain your having due to your injury.

      Thanks for Contacting Donjoy.
  • From Sharon Puryear at 8/27/2013 3:57 AM
    • I have been in an air cast following surgery. In 2 weeks I will transition to walking in the air cast. I will need a walking shoe for my other foot and want to have the same heel height as the boot. i am using a FP Walker, Medium 01F - M. Can you tell me the heel height on this boot?
    • Sharon,
      You should look at the EvenUp shoe balancer, it goes on an existing tennis shoe you have and will even up the height of your shoe and your boot. I have attached a link to said product here:
  • From malu at 9/15/2013 8:09 AM
    • I am wearing the race for the last 4 days. Under the foot the skin is irritated. I started wearing sock. Do I need to apply any cream for less irritation?
      If I use a walking stick/crutch, will it be better to heal faster. I have a tear in the tendon.
    • Malu,

      The FP Walking Boot should always be worn with a sock. You will want to contact your doctor about the use of crutches. Once the irritation has healed, wearing a clean dry sock should solve the issue going fourth.

      Have a great day!
  • From Penelope at 10/2/2013 4:53 PM
    • I have been reading reviews on the XP walker boot, and two ladies mention that the size chart is not accurate, one of them is my exact size, 9 1/2 to 10 1/2 and she says her foot is right up to the very front of the boot, so if I order the next size up the L fitting would it be okay even if a bit big. I have another brand of boot now and it is far too small, heel hanging over back of boot.

      I also need to claim this off my medical fund, so if I order in my full name will my name be on the receipt, as if not I cannot claim for it??
    • Penelope
      Thank you for contacting Product Support. The Aircast XP walking boot size M should fit a woman with a foot size from 8-11. If you are a size 9 1/2 to 10 1/2 this should fit you. The XP is a Pneumatic walker and has 4 air cells that are inflated after the boot is strapped up. If the air is not deflated before taking the boot off, when you stick your foot back in the boot the inflated air cells will not allow your heel to the back of the boot causing your foot to move forward. After time this can cause your toes to stick out at the front of the boot. As long as you deflate before taking the boot off, this will not happen, then you can re-inflate after putting the boot back on. If you have any other questions please let me know.

  • From John at 10/6/2013 8:12 AM
    • My daughter is wearing an aircast and it is slippery on any wet pavement, wlking to school in the rain is an accident waiting to happen. In addition, she works at an ice cream shop and the boot slips on the tile floor.

      Is there anything you can put on the bottom to prevent this? I thought of cutting some of the wave ridges to change the regular pattern as this appears to be the "skating point". Another option is to add black hockey tape (more sticky than white) to the bottom but this would peel off quickly.

      Any suggestion?

      Thank you
    • Unfortunately we don’t have anything more to add to the boot. Of the walkers we supply the AirCast line is the walking boot with the best sole. It’s designed to be more like a sneaker than other walker soles which don’t provide as much traction. Adding anything more to the boot would inhibit the sole from providing the intended traction.
  • From Susan at 11/11/2013 5:43 PM
    • My big toe and the next two toes hit the ground when I walk. I have a medium boot and wear a 9 1/2 shoe. Should I be walking differently or is there anything I can adjust?
    • Susan,
      If your heel is pressed to the back of the boot, your boot may be too small for you. Although the sizing chart states woman’s shoe size 8-11 would fit a Medium it sounds like you have a smaller size. A medium insole should measure 10” where a small will measure 9”. Check the insole size and if it’s too small you can exchange it for a larger size, as your toes should not be hitting the ground. Thank you for your question.
  • From John at 12/20/2013 4:38 AM
    • What is the purpose of the removable plastic liner that goes under the straps? Can I use the FP Walking Brace without it?
    • John,
      The purpose of the plastic liner is to add rigidity and immobilization to the ankle. It will also prevent the straps from rubbing and causing friction that may irritate the skin. It would be recommended you use the anterior panel for those reasons. Thank you for your question.
  • From Sonja at 12/22/2013 2:44 PM
    • Are the air cell sacs filled with any type of fluid? I had leakage of some type in my boot and could only assume it came from there. I was not to get my boot wet as I had foot surgery. Was not blood or fluid from my foot.
    • Hello,
      Thank you for your question. The air cells use only air to fill the cell. This brace does not contain any fluids.
  • From Joyce at 1/12/2014 1:08 PM
    • When going up and down stairs with the boot, should the good foot go first or the booted foot first?
    • Joyce
      What ever is most comfortable with you is ok. Sometimes I tell people "up with the good, down with the bad"

    • Is a Medium shorter in height than a Large? I wear 8 to 81/2 and the large is much too long, causing me to trip. It is also so tall that it makes it difficult to bend my knee. I understand a Medium will be an inch shorter in insole length, will it also be shorter in height?
    • Thank you for your question. The height for a large boot is 17.4" a medium is 16" in height.

    • I try to deflate my aircast with the provided bulb but most of the air stays
      in the cells. So how do I deflate the cells?
      This cast is a "wonder" and allows me to get around until the ankle heals.
    • Thank you for your question. When the boot is off you can apply a light pressure with your hand to empty the air cell. Some air will remain in the cell. Please contact us if you have any further questions.

    • I was wondering if I could get replacement velcro straps for my Aircast?

    • My boot was fit properly by a nurse on checkout. Now my toes fall asleep because there is more pressure on the ball of the foot and my heel does not stay down. Fractured 2nd, 3rd, 4th metatarsals with stable lizfranc.
      Shoe size 7
      Boot size small
    • Thank you for your question. A size small would be the appropriate size for a woman’s shoe size 7. Make sure the air cells are empty each time you put the boot on. You will need to re-inflate each air cell each time you put this boot on. If you continue to have problems, it would be best to contact your physician regarding this fit concern.

    • My husband has an old crush injury to his lower leg, it is also about an inch shorter, the hospital has made him a solid boot, but it is unstable, because of the way it was made. Can he wear one of these boots, as he has to wear it all day everyday for the rest of his life. Also can you get the sole built up so his leg is the same height as his other leg?
    • June
      He can wear one of these boots but it cannot be custom made with a higher sole. The boots already have a thick sole. Also, these boots are not made for long-term use(more than 6 months), although I have heard from customers who have had their boots for years, they wern't worn everyday. If he needs to wear it everyday for the rest of his life he may need to replace every so often depending on what he does in the boot.

    • Will the large fit around a calf that is about 20" around?
    • Thank you for your question. The AirCast FP walker accommodates a 17” calf. You would need to purchase the extension straps to accommodate a larger size. These straps are not available on Better Braces and would need to be purchased direct from the manufacturer 800-336-6569.

    • Aircast FP Walking Brace

      The size chart provided for this walking brace is it in Australian Sizes?

      If so I am looking for the proper brace size to fit a Women's size US 7
      (I believe that is a size 5 1/2 Australian).

      Can you tell me what size I should purchase?
    • The size chart on the US website is in US sizes. Sizes on the website would be in Austrailians sizes
  • From S at 6/28/2014 9:27 PM
    • How high off the ground is the boot? As in, what height shoe should I wear for the foot that isn't wearing the boot so that my feet are even?
    • The depth of the sole heel(Bottom to insole) is 1.5". We also have a prduct available that goes on the bottom of you opposite shoe called the Procare Evenup Shoe balancer
  • From Deb at 8/14/2014 3:47 PM
    • I have a broken ankle. I wear a size9 in a woman's shoe. The nurse gave me a large boot - sp walker because they didn't have a medium in stock. I can't adjust the air pocket at my ankle to be comfortable. It hurts my ankle where it's broken. Is this boot too big? Would a medium fit better? With a sock on, my toe is 1 1/4 inch from the tip of the boot.
    • Deb
      You should be in a medium, it would fit better and be more comfortable
  • From Jade at 8/14/2014 11:35 PM
    • Hi is there any way the straps can be shortened? I have a medium and I am around a women's size 7.5-8.5 and the strap for the top of my foot drags on the ground.
    • Jade
      Unfortunatly that strap can be made shorter, you could try tucking it in to the tob of the brace at the side.

    • What is the maximum calf circumference for the long brace. And how long does my lower leg need to be?
    • The calf circumference and overall dimensions of the boot change with each size of the boot, without knowing the size you would wear it is difficult to answer this question.
  • From Tracy at 10/2/2014 6:08 AM
    • I shattered my ankle and broke my tibia & fibula 3 & 1/2 weeks ago. I was given an Air Cast FP a week and a half ago. It is a Large 01F-L. I wear a size 9 or 9 &1/2 in everyday shoes and a 10 in running shoes. Every since my toes have been burning as if they are rubbing against the edges and top of the boot and my heal burns as well. I have to take the boot off several times a day just because of the burning. Am I doing something wrong?
    • Tracy
      First off you should be in a medium not a large unless you had a lot of swelling in the foot and ankle. Make sure that you are not pulling the straps too tight, or filling up with too much air. Lastly I would call your physician and ask them about the burning, it might not be from the boot at all
  • From Helen at 10/16/2014 5:48 PM
    • Is SP Walker latex-free? I have worn for the past week and getting rash on my lower leg.
      For the first five days after injury I had taller boot and no rash.
    • Helen
      There is no laytex in the walkers liner. It is made with nylon and polyester

    • I have a stress fracture in my tibia, would this work for me? My doctor said it started to heal and did not mention any type of casts or walking boots, but I feel like i need to get weight off my foot.
    • Angelica
      Yes the FP walking Boot can help immobilize the ankle and take some stress off the leg while that stress Fx heals

  • From Kim at 1/16/2015 8:23 PM
    • Is there any way to reverse the direction of the straps/fastners. I have the boot on my left foot and the straps fasten to the left side. I also have scoliosis and a shorter right side which inhibits my reach to the left side - leaving me one handed to try and fasten the boot which is impossible. if I could reverse the straps to fasten on the right I would be able to reach with both hands.
    • Kim
      The bottom Strap cannot be switched at all, it is bolted on to the boot shell. The two top straps can be removed and turned around if you can get them loose. We do replace thoses traps if they break but it is very difficult to unattache them. They are attached by a plastic disk on the back of the boot.

    • my doctor diagnosed my ankle pain as Capsulitis . I am to purchase a MAXTRAX AIR WALKER I perform many physical duties at work including excessive walking and lifting.Will I still be able to work and perform all duties while wearing this boot
    • Mark
      You will still be able to walk while wearing the Max Trax Air Walking Boot. The Boot has a rocker bottom to help simulate normal gait, so you should be able to do your normal activities in the boot
  • From Patricia at 5/27/2015 6:55 PM
    • The valve on one of the air cells on my XP cast does not function. Is there a replacement part?

      We do have replacement aircells by calling DJO direct at 800-336-6569
  • From Mike at 7/19/2015 7:23 AM
    • Is this boot effective to treat sesemoiditis in the big toe? Will it relieve pain or should I still expect there to be some pain while wearing the boot?
    • Mike
      The boot will immobilize the foot which will decrease pain when walking but may not eliminate the pain completely
  • From Tracie at 7/26/2015 8:20 AM
    • I fractured my heel bone recently and I am currently in a medium FP Walker after a fiberglass cast for two weeks. I am five foot tall and I wear a 7.5 shoe, & the cast just seems too tall and it causes pain at the site of my injury. Should I go down to a small XP Walker or would a short aircast work better?
    • If your physician is requiring you to be in a tall walking boot you do not want to deviate from that without first speaking with them. In regards to the sizing, based on your shoe size you should be wearing a small, for a better fit.
