Works for me

The best thing about this one is the price. It replaces the one I got when I came home from foot surgery 11 months ago which was beginning to lose it's zip. That one cost my insurance almost 3 times as much as I paid for this one.

Absolutely LOVE this brace!

This brace has been a staple for me since the day it arrived. I am 6 months into non-surgical treatment for a minor lis franc injury and this brace allows me to be more active than I have been in months! So glad I stumbled across the recommendation in a blog, I couldn't be happier!

Perfect Brace!

For 6 months I have been struggling with PTTD. My podiatrist put me in a walking boot for 2 months, however, little to no improvement was made. After researching and reading many other reviews of this product, I thought "what do I have to lose?" and purchased this brace. The day the brace arrived at my house I had a very strenuous day at work and my foot was already throbbing by the time I got home. I was excited to try on the brace, and much to my amazement, the pain was gone on the very first step. It has been a week now of wearing this brace religiously, a pain-free week; no more agonizing first few steps of the day, no more 20 minute ice-pack sessions after work, no more agonizing long days on my feet. The Bio-skin Trilok brace is hands-down the best thing I have tried to relieve the pain associated with the PTTD. Also, the Braceshop had the best price I could find, and when the USPS flubbed the delivery, the customer service at the Braceshop was friendly, courteous, and quick to resolve the issue.

After trying other braces and cortisone shots for my arthritic ankle, my podiatrist finally recommended the trilock. Wow! I'm able to play golf, hike, iron, stand on my feet for hours with no pain and additional support for ankle pronation. I have encouraged friends to try it out. Washable too.

Pttd Relief

I love these braces. I have pttd and was wearing aircast braces which are much bulkier and stretched out my shoes. These bioski n work well with my custom orthotics. I do not use the white strap when wearing my shoes. My shoes are happier too.

Bio Skin TriLok

I had an invasive ankle surgery back in 2014' that I am still dealing with. Lots of arthritis and scar tissue took over where the cadaver cartilage did not take. I am very involved in a lot of sports which you can imagine what this surgery did to me!! Anyways the bio skin trilok is my savior, my favorite sports are tennis and racquetball so without this brace I would not be able to play the court sports. I actually have 4 of them now, two of them warn out but still doable. I will be a lifer!!!

Brace was too small and too complicated for 80 yr old.

Best brace

Extremely comfortable, way better than the lace up type from sports authority... Keeps your ankle stable, fits in shoes.

Great brace for PTTD

This brace works beautifully for PTTD. A little bulky for my foot in my shoe + orthotics due to tailor's bunions, so I'm also trying the Malleoloc brace which is a little less bulky and leaves my toes less crammed. I agree - brace without white strap works best in my shoe, but I can feel the difference the white strap makes. The velcro stays put all day long. I will also get pain in my left foot, but when I wear this on my right PTTD foot, the pain is gone in both. In order to wear any brace, I moved from wearing Asics Gels size 8 to Brooks Ariels 8.5 Wide. The Brooks have a roomier toe box and don't even get too stretched out from the brace.
