This knee brace was the first one I found that helped my skiing injured knee, and I was pleased to see that McDavid still offered it when I needed a replacement. It is a good solid product, well made and durable. IT provides good support without hinges, so it is lighter and more flexible.than some braces. This one is good for walking or hiking. I also bought the version with cross straps, and that can be made tighter and more supportive. It is easy to get this one on but more difficult to get off.

I bought this brace to help support my knee, which has some nerve damage, and help me get around better. I have trouble supporting weight and making sharp movements when I play sports. I received the brace about a couple weeks ago, and have been wearing it ever since.The first day, it was uncomfortable and odd to walk in. It took a few tries before I could position it correctly. But I figured I just had to power through and break it in.The second day, I was a little more used to wearing it and I even forgot I had it on at times.By the third day, I could slide it on and forget it was even there.It's comfortable, shaped itself to my knee, and pretty lightweight. I sweat under it on hot days but it never feels wet or uncomfortable. It doesn't even smell bad ...

It doesn't even smell bad despite the fact that I've mowed the lawn in it, stood around a campfire, and went fishing multiple times.It honestly has made such a noticeable difference in my life. There's less pain and less instability when I walk. I'm more comfortable moving heavy objects and excersizing more often without a fear of hurting myself. My overall function has improved drastically. Whether it's a short walk or a workout session, I take this brace with me wherever I go.The only downside I can find about this brace is that it's a little hard to get off once I've been sweating, but for me, it's hardly an issue.The support and confidence this brace gives me for the price is phenomenal. I was a little nervous because I hadn't tried McDavid before but I'll definitely be reordering this brace once I wear my current one out.

Have worn it a few times since it arrived. Seems to support the knee pretty well, though I get a similar feeling from a well-wrapped 4" stretch bandage. For me, it seems to run large, as I bought the size recommended, but when pulling the straps to get good compression, the neoprene bunches up a bit. I would probably be happier with it if I had bought one-size down.

Fits as designed. Comfortable with excellent compression and support. I can play pickleball for hours with minimal soreness afterwards. Use the fitment guide to determine your size. Recommend these supports for anyone with knee issues.
Quality is amazing. I was replacing an older model that had worn out after 5+ years of use. I did not review the size chart and ordered a large which was really small for my knee. I ended up reordering and getting an extra-large. Fantastic feel and is much better than the 5 year old model I was using.
The picture associated with this product is no longer valid. It has a new wrap around system, not a pull up system. The new design is poor. If you pull the 'wraps' tight (which you need to in order to get the support) they completely cover the patella.The poor design of the website does not allow me to attach a picture.
Wasn't sure the brace was going to help support my knee while horseback riding, but it did. I'm able to ride again after sustaining a significant knee injury due to a bunch of playful dogs taking me out.Thank you McDavid for developing such a high quality knee brace. I really like the way it fits and pulls on. Your webpage is extremely helpful in my making the correct choice of brace I needed to support my knee.
The impression of my knee was: Root tear of the posterior horn of the medial meniscus, Baker's cyst and Grade IV chondromalacia at the anterior aspect of the medial femoral condyle. Trying some alternative to continue playing tennis: no prgress. With the Knee Support w/ Stays - Black / Adult-XL, I could continue playing. And know I feel close to completely recovered.
We had bought one before but had gotten old & worned out. We simply ordered one to be exactly the same, size, brand number & all; but unfortunately this one didn’t come with the same metals side bars’ support as the 1st one. It’s tight because it’s new but it’s not the same.
I injured my knee and I'm not exactly sure what's wrong with it yet, won't have medical for a bit, but I've been suffering on and off for going on 2 months now. from the reading I've done I'm pretty sure it has something to do with the meniscus, but I could be very wrong. knee braces have seemed to help and I've been through a few of them- both simple elastic sleeves and hinged braces. some actually made it worse. my last hinged brace was from Mueller and while it helped a little bit in the beginning it wore out pretty quick. I debated on this brace for a while because of the cost but I took the splurge and for me it was completely worth it! I felt some relief in my knee which had been aching all day within minutes of putting it on and the design and the material is ...
