* Required Fields

The TriLok is a versatile ankle brace that provides protection, support, and pain relief from multiple foot and ankle injuries.

Ankle Sprains
The TriLok provides protection and support to injured ligaments to prevent further injury and reduce pain after a sprain. The FootLok Strap acts as an external ligament, using leverage to protect the weak or vulnerable ligaments around your ankle. The FootLok strap wraps around your midfoot and then attaches to the outside of your ankle. You can adjust the level of support by pulling up harder on the FootLok strap. The TriLok also includes stirrup straps to increase the stability even further.

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. The TriLok’s FootLok strap lifts the arch and relieves pain by correcting over-pronation and restoring the foot to its natural position.

Plantar Fasciitis
The TriLok alleviates plantar fasciitis pain by lifting the arch and supporting the plantar fascia. The FootLok strap wraps around the midfoot and allows you the ability to deliver adjustable support, by pulling up on the plantar fascia. The TriLok may also be used as a light night splint to hold the foot in dorsi-flexion while you sleep.

Peroneal Tendonitis
The TriLok's FootLok strap mimics the function of the peroneal tendons, attaching to the midfoot and lifting the outside edge of the foot. As the FootLok strap lifts the outside of the foot, it offloads the peroneal tendons, allowing them to heal and regain their ability to support and protect the ankle.

    Hopefully I have found a solution - I have a previously broken ankle which is weak and lets my foot roll inward. The distorted position of my foot has allowed calluses, blisters, and chafing to occur in the arch area of my foot. I know that I have to do something to keep my foot correctly supported so that it says healed. The doctor's solution is a hard plastic, calf-high Ankle Foot Orthotic which feels like a torture device out of the Dark Ages. It's uncomfortable, awkward, and throws my balance off. I totally hate it.

    I found the BioSkin TriLok online and decided to try it. I studied the videos and BioSkin sent me a link to the .PDF user manual, so learning to put the brace on went very quickly. When it's on my foot, I can feel my foot being pulled back to the outside which hopefully will take enough pressure off my arch that I won't have more problems. The TriLok is very easy to wear and doesn't interfere with my activities.

    I had a problem with lining up the back of the undersleeve and the black strap with the back of my heel. I took a light colored thread and sewed a few visible stitches on the back of the undersleeve and on the center of the black strap. Now, all I have to do is to line up the thread indicators with the back of my heel and then line up the thread indicators on the undersleeve and on the black strap. It would be great if BioSkin could add little dots - having a way to line everything up makes putting on the brace much faster.

    I hope this ends up being a long-term solution to keep my foot healthy.

    I purchased this brace to help with support as I have early Stage II PTTD. The therapy I am currently doing calls for a quality AFO (Ankle / Foot Orthosis) and this product more then fits the bill for that. My first observation was in how well made this product is. It is a quality brace that should last a long time. Replacement straps are readily available via this web site with fair pricing and free shipping. Awesome.

    This brace seems more complicated then it is. It took no time to browse the plainly written and concise manual and I was up and wearing the TriLok in no time. The support it gives the ankle is nothing short of incredible. The ankle is locked in place and rolling the ankle appears to be virtually impossible. Movement of the foot up and down is not restricted in the least so overall the ease of walking on uneven ground is greatly improved. It is comfortable and fits nicely in my New Balance 663 Heritage shoes. Wearing this brace with my Red Wing boots will not happen, but I assumed that going in with this brace. No problemo there.

    Final observation is the arch support of this brace alleviates the pain I am having on the Sinus Tarsi. Being a Stage II pain will migrate to the outside of the foot with PTTD. While it was not severe to begin with, pain level has been somewhat reduced while wearing the TriLok and that is a huge plus.

    I would 100% recommend anyone who has PTTD to purchase this product and to wear it in conjunction with a good set of shoes.
