DonJoy Performance POD® ANKLE SUPPORT - Black - Medium - Left

I've been shopping around for an ankle foot brace and decided to try this because it's so different from the typical ones. Definitely easy to put on, fits easily (I have a relatively skinny ankle measuring 7 3/4 in with foot size mens 9.5), comfortable and fits inside of shoes. I wear it with a compression sock or sleeve underneath for a good fit. Some regular athletic socks seemed too fluffy or didn't quite stay put as well.Does it work? Depends on what you need... the POD brace allows for a flexible range of motion which makes it great to wear easily with your existing shoes if you're prone to rolling and spraining your ankles but otherwise functional and not injured. But it's not literally bracing your ankle if you have weak ankles. It's preventing ankle rolls/sprains because it limits the possible motion of your foot rolling inwards and keeps your foot aligned. I appreciated that there's still some range of motion so that I could wear the brace without my foot atrophying from being overly restricted unnecessarily.I don't have a sprain in this case however. I have posterior tibial tendonitis and just broke an accessory navicular bone (blah chronic injuries), so no this brace is NOT for my PTTD. I've been searching for something that supports the navicular bone where the posterior tibial tendon attaches in the arch closer towards the heel than most plantar fasciitis options support. This brace fortunately covers that spot and is almost rigid. It makes up the the difference between my navicular bone and orange Superfeet orthotic (for when I'm active) so I have rigid, full contact support right at my problem area. I'm also wearing a compression sock/sleeve underneath the brace so this whole franken orthotic situation gives me the most flexibility depending on if I'm just walking around casually or being active. My doctor was so uninterested my chronic, open-ended problem so I hope this review can help somebody out there.
