    So far i find it helpful but somewhat difficult to put on.
    The velcro is tricky to work with but good because of its grip action. I like that it is slim and not bulky in design so i can wear my shoe. Getting better at putting it on. hopefully I will improve with time. Some concern
    with how it will wear with time. Especially the white arch support. Supports the arch different than an orthotic which is an improvement.

    My PTTD kept me off the hiking trails for months. I tried all kinds of braces but only this one actually helped. I wear it every day, usually with some kind of mid-high hiking boot for support and I've been back on the trails since. And, if anyone needs a boot recommendation-Salomon Quest 4D has worked the best for me.

    I could not be more satisfied with this brace. I've tried other braces in the past. None come close to the support this one offers. Was a little tricky getting everything right, but now that I know which way works best for me. OUTSTANDING!!!! I will buy another when this one wears out.

    Quality product. Holds up very well. Helping with my posterior tibial tendon dysfunction. Like them so well that I have one for work and one for around the house. Have to tighten straps once in awhile otherwise very good product. One of the best out there and recommended by my clinic.

    Very impressively the brace was delivered the day after ordering it. I have used other ankle braces before and changed to this one with the advice of my foot surgeon. There is no comparison in the comfort and support this brace provides. Glad to support an Oregon business

    My son was very happy to receive these as he has PTTD; being an Elite Track athlete, he works his body hard, but he has a peace of mind he's being supported with these braces. Also, I can't remember the Customer Service individual I spoke with, but he was extremely helpful and pleasant and personally took care of the order speaking with the warehouse people to ensure my son receives in time to train further for Sectionals in his state meet.

    I found this brace after doing a Google search for solutions for Posterior Tibial Tendonitis. I was going on a trip to NYC which called for a lot of walking and I was in a good deal of pain. This brace saved the day. It gave me the arch support I needed and supported the damaged tendon to reduce the pain and swelling. The brace fit into my walking shoes. I high recommend this brace for anyone suffering from PTTD.

    My PTTD has been painful and this brace pulls up the arch for the support I need, and along with my orthotics, have allowed me to put surgery on hold.

    This brace works for me perfectly and I wear it five days a week in a jazzercise class. My only wish is that you had an under sleeve in a size between the small and medium. The medium is too long on my foot and the small is somewhat tight.

    Since using this I am able to bear some weight on my foot from plantar faciitis, muscle and connective tissue damage. The nerve firing has been significantly reduced in an area that might have a trapped nerve. Occasionally I use it at night as well and it helps to give enough support if my foot is moved and I don't wake from the nerve firing. Without this brace I was unable to bear weight on the foot and control the severe intense nerve firing.

    This is a very supportive brace for me after two ankle joint replacements. I think I have posterior tibial tendonitis and the brace keeps my ankle stable. It fits into a regular sneaker-type shoe very well because the foot part is not too bulky. I was able to wear it all day and walk all over Manhattan. I have tried lots of braces and I like BioSkin the best.

    I dislocated my ankle medially and fractured my subtalar joint. I had to get surgery and it was a long healing process and its still healing. But my ankle just started hurting again for some odd reason and i could barely walk. The ankle brace that my doctor gave me wasnt helping so i put my bioskin brace on and it helped so much! Its tight around the subtalar joint (which is good) and pushes the swelling right out. Its very supportive and i would reccomend this brace to everyone with ankle issues

    Unfortunately the brace doesn't seem to be helping... and also is adding a numbness with a bit more pain to my original issue.

    I love this brace because it makes it possible for me to walk around without terrible foot pain. However, I have had to buy several because they do not hold up well. The plastic ankle shields wear through the black fabric and have to be sewn. The lower front strap fell off. The velcro wore out and didn't stick. When I washed the straps the white one especially shrunk. I think it would be instructive for you if I sent back my worn one for you to see how they wear so that you could perhaps improve them.

    It seems odd at first, but all three straps replaced my hard plastic splint from the ER perfectly. As my ankle healed, I would leave one strap off, then the next until I was free! Great product, great support and much better than the boot walker I got with crutches.

    It provides great support. The only real thing I didn't like is it runs a little to small in the calf and the piece that slides on the foot is so tight it can be difficult to get on and uncomfortable if worn without a sock.

    I fractured my ankle 12 years ago, fixed with a lot of metal.
    It had been constantly painful, sometimes acutely so. I always walked down steps holding a rail with that foot turned out, to ease the pain.
    Finally a podiatrist ordered a BioSkin TriLok for me, and since the first moment I put it on, I have had NO pain at all.
    I wore it every day for a week or so, sometimes also to bed, but now I wear it only when the ankle is a little sore. It truly is an extremely comfortable, effective support. I am disappointed that the orthopedic specialist did not suggest it years ago, but I will be sending her the link, so hopefully she can review it for herself and help others like me.
    I cannot praise highly enough!

    My regular Dr. referred me to a podiatrist due to numbness and discomfort in my left foot. The podiatrist quickly diagnosed that I was walking on the inside of my foot (I believe this is called over-pronated?) due to my flat feet. He prescribed the TriLok and the nurse showed me how to put it on and the correct direction to wrap the white strap.

    I wore it continuously for the next month or so (even to bed a few times), and experienced a lot of discomfort as the nerves in my foot seemed to wake back up (tingling and burning was, believe it or not, better than the numbness). After about 4 months, I started wearing the TriLok every other day, and eventually tapered down to about two times a week.

    It's now been 9 months and I only wear it very occasionally, when my ankle is feeling uncomfortable. I've pretty much worn out the velcro at this point, so I'm back to buy a second one. I never did return to the podiatrist to be fitted for custom orthotics; I'll just keep using the brace occasionally.

    This is a great product and worth every penny, especially when I consider that I must have about 180 days of wear and tear on mine before needing a new one.

    Preliminary review - it took a couple tries to get the hang of how this works and to get it aligned properly for maximum support. I will advise that it runs a bit small if you have chunkier calves than normal. I think I'll be okay with this, as it is giving EXCELLENT support on my interior ankle bone where no other ankle support/contraption has. It's real support.

    Air casts don't really do much, there's still a lot of side-to-side movement and whatnot. With this BioSkin, however, wrapping it based on the instructions (there's instructions based on how to use the wraps depending on the type of injury or weakness you're looking to support) feels VERY odd -but I'm so used to walking pronated that this isn't a surprise. Guardedly, I can say I'm walking at 85-90% pain free (on a scale of 1-10, prior to this application, it's been about 8-12 in pain level especially hiking on uneven terrain) on concrete/asphalt, the bioskin dropped it to about a 3 almost immediately. On the uneven terrain, 4-6 because the ankle's still going to roll some and it had only been on for about 20-30 mins.

    I'll follow up if there's changes or it falls apart or anything like that but as of now, I'll be wearing it all day, daily for at least a week and see if this tendon can finally get healed up so I can wear this less and less.

    I have Ehler's Danlos Syndrome. I have been battling chronic Plantar Fasciitis and Sinus Tarsi Syndrome on the left, and chronic tendonidis on the right for almost 2 years now. I have had numerous steroid injections, night splints, exercises, etc. Because of the Ehler's Danlos, I was already wearing braces on both ankles, but they were thin, and didn't provide much support. About 3 weeks ago, my Podiatrist introduced me to Bio Skin TriLok braces. I can walk almost normal for the first time in years! It is not likely that the pain will ever completely go away, but these have given me the stability that I need, and I so thankful for that! They are easy to put on and comfortable to wear.

    After I sprained my ankle, my PT recommended this brace. It is FANTASTIC. Without it I would not have been up walking. It came quicker than expected. It is easy to put on and off and is comfortable to wear all day. The wrap around strap is what really supports the ankle. I highly recommend it!

    This is the best most comfortable ankle support I have ever had. Worn one out after 3 years of use, as a multiple ankle break and strains this brace keeps my ankle safe and me on my feet. Can be worn very comfortably with tennis shoes, dress shoes and sandals, etc. Wow this is my second and I hope they never discontinue it.

    Whilst playing squash I went over on my already weak ankle, I played again and when all tight on the brace there was no way I was going over my ankle again. One downside with it tight for me was I got cramp in my foot, so I loosened it off and low and behold I went over my ankle again, if worn tight it is fantastic in fact unbeatable.

    2 years ago my podiatrist diagnosed a torn tendon in my right foot. A boot was the first plan of attack which merely caused hip problems. Surgery was the second. I said no I would wait until it put m totally out of commission before surgery. I have been wearing the TriLok ankle brace for 2 years and am able to play tennis 3 hours a day without a problem. The ankle is almost as good as new without surgery. I only wear it for preventive measure and only playing tennis. It works for me.

    My very first product review I've ever bothered writing, because it really is THAT good. It's a little intimidating to figure out at first, and it's a lot of money for 2 strips of velcro and a velcro sleeve. But that's because this is a totally new concept in ankle support. I've had 3 others, and nothing comes close: the most effective, comfortable, and elegant by far. I'm ordering another for my "good" ankle, just because it feels so great to wear.

    Ran for the first time tonight in a long time! 16 months since my last surgery and 28 months since I broke my ankle and leg. Felt pretty dang good. Especially since my knee feels more sore than the ankle...haha. Thanks Cropper Medical for zipping off to me a BioSkin TriLok ankle brace! Made me feel much more confident in getting it done.

    I have broken my ankle 3 times and badly sprained it another dozen times. I am 33 years old and have been living in tight, stiff, ankle pain for 10+ years. I always put the pain to my past, what I didnt realize is my flat feet cause chronic Plantar Fasciitis. I do a lot of half marathons and beat my ankles and feet up. After 3 nights of wearing this to bed I wake up and remain pain free! It has been the most amazing feeling! I am pain free!!!

    The best ankle brace I've ever used and I have had every type of ankle brace including a caste in my 68yrs and my left ankle ligaments are wasted...also blew out left achilles tendon so probably not candidate for ankle joint replacement. But this could be my savior until BioSkin comes up with a better solution. At least I can golf without high level pain. Thanks

    My son last year unfortunately had a high ankle sprain in Football requiring ligament surgery. After months of therapy he is 100% and uses this brace during all his workouts and games. this brace is by far the most comfortable product on the market while offering the "correct" support for his injury. the versatility of this brace is amazing. The flexibility of this brace has not slowed him down one bit and provides him the peace of mind needed to play at peak levels. We carry a stock of these braces at home and rotate for him. He will not consider any other option on the market-this is a one of kind, awesome brace. Fantastic product!

    This spring I had a flare up of arthritis in my ankle which was previously broken, it has really helped me to keep me on my feet and after about a month I have been able to go without it depending on what I'm doing. got to keep moving and the tri-lok has really helped to keep me active, without it I would have missed work.

    I've been using the TriLok for 4 years now. I have tried other lace up braces but none compare. I experience extreme pain from Plantar Fasciitis that affects the arch of my foot. The TriLok provides great arch support. I wear my brace walking, waitressing, running, exercising and dancing. It fits into the majority of my shoes even while wearing thick orthotics. After a year of using the same TriLok brace it became very worn out.. as would any brace. But this is the best I have experienced so far.

    I believe I had the worst case of plantar fasciitis there is. I tired many therapies, including your typical physical therapy, wrapping with tape, generic orthotics, then custom orthotics, then a specialist in orthopedic physical therapy, cortisone shots, exercises, night splint. This went on for a year and a half and I was in horrible pain and walked like a cripple, unable to do anything routine without pain. FINALLY I took the advice of my podiatrist and went with the TriLok brace.. To his credit he did mention it in one of my initial visits, but I opted for the cortisone shot thinking it would be a quick fix.. From the moment I put it on I felt some relief. He said to wear it from sun up to sun down for 2-3 months. It is AWESOME!! It has now been 4 months and though I still wear it for exercise and when I plan to be on my feet a lot, my pain is 90% gone and I am back to my normal routine. Since walking is my only form of exercise, I was gaining weight, cholesterol went up and blood pressure escalated, so I am so happy to be back to "NORMAL." I highly recommend this brace for anyone with plantar fasciitis! Very comfortable and fits nicely into my athletic shoes. It is worth every dime!! And NO I am not being paid by anyone to write this review. It is the honest to God truth!!

    My daughter has been using the trilock brace for a couple of seasons now and it has been fantastic. It actually provides two different levels of support depending on whether you use the white "lock down" strap. Unlike all the other braces on the market you don't have to worry about the laces digging in or becoming loose because there are none. However, it provides more support than lace up braces. For the most comfortable with true support give this one a try. It also fits nicely inside of Hyperdunks.
