TriLok™ Ankle Brace for PTTD

The TriLok relieves pain from posterior tibial tendon dysfunction, or PTTD, by wrapping around the foot and lifting the arch, just like a healthy posterior tibialis muscle does.

Included in the package: TriLok Undersleeve, Stirrup Strap, and FootLok Strap

* Required Fields



The TriLok offers an innovative approach to relieving the pain associated with posterior tibial tendon dysfunction, or PTTD. The key to the TriLok’s effectiveness is the patented, white FootLok strap. This strap mimics the posterior tibialis, the muscle/tendon structure responsible for lifting the arch of the foot. When the posterior tibialis becomes weak or damaged, it loses its ability to lift the arch properly and allows the foot to begin to collapse. The TriLok’s FootLok strap lifts the arch and relieves pain by correcting over-pronation and restoring the foot to its natural position. Watch this video for more information on how this works.

    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.

    I have experienced great relief from Post Tibial Tendon Dysfunction, which surfaced after I dislocated and suffered a Trimalleolar ankle fracture. What's even better, the orthopedic surgeon who is treating me, approves.

    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 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 recently acquired a Trilok brace for my flat feet and PTTD in my left ankle. It is amazing what a relief it provides. I feel like I can walk without feeling that I am going to fall . It gives such great support for my ankle, I wish I had started using it years ago. Thank you for this great support. It is easy to apply and gives great support.
