This boot really does work!
This ASO boot has really worked for me. I have a peroneal ankle tendon overuse injury, and this boot gave my foot enough support that I could walk. Without the boot the ankle tendon was very sore, rubbing against my winter boot. With the ASO boot on, I was able to walk without feeling any pain. The design is well thought-out and despite wearing it for a couple of hours per day it is still effective and sturdy.The Velcro is extremely strong; the fit and comfort are very good. I'm ordering another one to have as backup.

Stable and durable
I had one of these for each ankle from high school sports, they lasted me at least 10 years. I finally needed a new pair and feel the quality is still there. They are a little bulky and can crease if the heel straps are pulled too tight but if you take the time to get them fitted correctly they are game changers and I find them comfortable. They do take some time to apply but it is worth it, especially if your ankles are as weak and tend to roll (or break) like mine do. They are supportive and will help your stability but not compression. Highly recommend if you have ankle instability and want to keep playing sports.

Great ankle brace, that doesn’t affect my Plantar Fasciitis.
I’m recovering from a sprained ankle, and I needed added support to accommodate my semi-active lifestyle. I have severe Plantar Fasciitis, which makes it difficult to wear certain products. I tried multiple ankle support devices (ankle support compression sleeves, ankle support bands, and even changed my shoe insoles to aid in stability). Regardless what product I used, they caused excruciating foot pain, because these products would put direct pressure on the Plantar Fascia. I saw this brace, and it appeared the straps didn’t cause direct pressure the Plantar Fascia. I was correct the straps cross over, and go directly under the heel and come up the sides. The brace does cover a portion of the Plantar Fascia, but doesn’t cause constricting pressure. I would say it provides medium support, and allows adequate movement for some sports. I’m a 8.5 mens shoe size, and the (small) fits excellent. The only issue I’ve found, is a calf-sock is needed under the brace to prevent chafing from the seems, and since the straps run under the heal it can be difficult to put in a tight fitting shoe, which will pull the straps out from under the heel, so I loosen up shoe laces to allow for insertion. I ride a hover board, which puts excessive strain on my ankles, and the occasional spontaneous dismount can be tragic for my ankles, so I ordered a second for the other foot out of precaution.

Comfortable and support in the right ways.
First of all I recieved this in record time. 48 hours to Southern California. I have played soccer for over 10+ years, rugby for 4+ years, basketball for 8+ years and ran track and field for 8+ years. For the first time ever, while playing basketball, I sprained my ankle. Grade 2. Partially torn ligaments. Its been two weeks and I still can't walk with a normal stride. I am ordering this so that I have support while I walk around during my daily activities. This is the first brace I have ever tried or ever worn. Size: I wear a size 9 shoe and 13 inch ankle measured around the heel. I fell within the small or medium size according to the sizing chart. I played it safe and and went with a small. The small is a great fit. Its really snug and I'm sure if someone's foot was a little too big for the small, this brace could accommodate. Also, this fits into my shoe no problem. Fit/Support: The first thing I noticed is that the middle of the laces are stitched onto the front part of the brace. This will help keep the laces even and help keep things lined up. I laced up the brace and this first layer of protection is pretty firm and comfortable. This lace up part of the brace prevents over flexing your foot up towards the sky and down to the ground. I wanted to restrict the most movement as possible of my foot and laced them pretty tight. The figure 8 straps are where the real support comes in. The straps reinforce the up/down resistance that is originally provided for by the lace up part of the brace. The velcro on the side for the straps is on the brace in a way that helps you align the straps to the proper position and same way every time (just like what stitching the laces onto the brace will do). Not only do these straps greatly reinforce the up/down resistance, because of the way the straps wrap around your foot and back to the same side, these straps will work to resist the "rolling" or eversion/ inversion action that leads sprains. Then to top it off there is a final strap that wraps around the top of your ankle above the ankle bones... the "high" ankle area. This strap gives good compression as the other two parts of the brace does. It also secures the laces so nothing gets loose. Range of motion: When sitting, with no shoes on, with my foot flat on the ground, with brace as tight as possible, while not cutting off circulation, the brace limits heel from rising to about 1/3 the distance off the ground compared to my other foot. Again, I am still recovering from the sprain so this low range of motion might be due to the sprain. If I loosen everything up the range of motion frees up. The straps still prevent rolling of the ankles however loose the lace up part of the brace is. I can move my foot left and right which is good and the brace does protect from moving the foot left and right too much. All ranges of motion are protected for. Compared to a professional athletic trainer's tape job, this gives less support but more range of motion. Rating: The reason I gave this four stars instead of five is because as a life long athlete I have had to tape my ankles up before and this brace just doesn't give you that total all direction firm security. This brace mimics when athletic trainers tape the ankle in a lot of ways, the lace up part of the brace mimics the base layer of ankle taping and the figure 8 straps mimic the tape layer that goes around the heel from outside of your foot to the inside. In my humble opinion, the part of real athletic trainer style tape job that this brace is missing, is the the layer of tape that goes from the middle of your foot, past the heel, then ends at the achilles/ calf. This layer of tape keeps the foot bent at a desired angle. This layer helps keep the heel off the ground and adds resistance to accidentally flexing your foot too far up and jamming the front part of the ankle. Comments: As an ankle brace It provides great support and keeps everything real tight and compressed. I couldn't say how well it compares to other braces. This brace does not fully mimic a real tape job which I suppose is one of its intended purposes. This brace will help to prevent respraining if you heal up to 100% because it adds resistance to the inversion, eversion motions and adds quick support in all the right ways. This brace is way faster than a tape job and for my purpose, the need for extra support while walking around, its awesome. Because it can't fully mimic a tape job (and I don't suppose any brace could), I wouldn't have 100% confidence in this brace to replace a tape job and confidence is everything in sports. TL;DR: Lots of support in a way that will resist ankle sprains. Way faster than taping your ankles up, but not as good. Really comfortable and shipped super fast.

Good Quality
I’m recovering from ligament tears in my ankle, and couldn’t walk for weeks. But now I’m starting to walk and this helped me walk normal again. Very good quality and support

Doctor suggested this for ankle injury.
Doctor suggested this, using it, very easy to wear, but i injured my hand as well, so be careful if you are injured your hand, it will be a bit stress to wear it, but its my problem, hopefully other people don't face it. Product wise very comfortable, and helps me a lot. I have to wear it for my fractured ankle.

Useful for light support of injury.
This is somewhat useful, it helped a bit with my newly sprained ankle. However it did not fit well. Instructions specify making sure it is laced up tightly and laced up evenly, however the laces stretch while being used. The wrap-around straps with velcro attachments do stay in place well, and help with support, but don't make up for the lack of plastic or metal stiffening on each side of the ankle. They were well made.

Tobillera de calidad superior. Ideal después de dos operaciones de tobillos para volver a jugar al pádel y deportes de impacto. Es la mejor. Agarre y estabilidad.

今までスタンダード(プラスチックが入っていないもの)を使用していましたが、プラスチックの取り外しができるものも、とても良かったです。どちらかといえば、取り外しができるこちらの商品の方が良い!到着までは時間が掛かりましたが、どこを探してもなかなか見つからない状態で、購入できたので良かったです。

Can't use the product. Wanted MEDIUM. Didn't realize you don't have anything bigger than EXTRA SMALL. A waste of time and money.

Been struggling with ankle problems A LOT. These replace all the taping I have to do. They are comfortable. They give plenty of support. They are easy to clean. So far, absolutely recommend. I am back at playing football 4 times a week after month and month of physio, the braces are now making the important difference.
