Good brace for son's knee
My son is using this 429x for football. It's providing good support and stability for his knee when he's cutting out on the field. It's a quality brace that's easy to get into and out of.

Great brace for basketball
I have problems with pain around my kneecap but can't give up my favorite sport. I've been using this 429X for about three years now and I swear by it! The cross straps help cinch up the support of the donut in front better than my other stabilizing knee sleeves, and the hinges on the sides give me the support I need when I'm on the court. The service and shipping here were fast - got my brace order in two days. Very pleased.
Excellent product. Great fast service
Excellent product Great fast service. I'm very pleased with my purchase.
Fits perfectly
My brace fits perfectly. I'm 6'1" and weigh I have a 15'' knee measurement and if you look at the chart for sizing, that's a size Large. No complaints.
Just Great
Ordered two of these with the crossed straps and they've provided my knees with great stability and support.
Fast replacement needed
I bought two these and one of them fell apart with the stitching. The company did more than I can describe to help us out. A new brace was sent out at no charge, and the old brace was returned so the manufacturer could analyze the problems. If you need a strong, supportive brace for your knee, this is well worth considering.
Happy - five stars
Was on the border between two sizes and went with the larger size - very happy!.
Generally happy with it...
The quality of the material is good and I'm pretty much happy with it. It seems to run small so I recommend if you are within the upper limit buy the the next larger size up instead of what you think is the actual one. The back of the knee is also fully covered - I prefer it with empty space instead to reduce the bunching and give more comfort when you're walking.
Runs small
Bought the Size XX-Large but it was too tight - had to return it. Otherwise it seems well made.
Good Hinged Knee Brace for Sports
I have a partially torn medial meniscus which happened during a recent pickup basketball game. I waited 3 weeks for the swelling to subside and got an MRI. I then had to make a choice on what would get me back to playing ball the safest/fastest. The answer was pretty obvious-- I needed a good knee brace that was hinged on the sides and would keep by patella supported, off load some stress, and make sure I wouldn't injure the knee any more. This seemed like it would be the best support brace that would work well without breaking the bank. I ordered the XL size and was able to return to playing on the court. My first week back I played in 3 league games. The first game I spent getting used to the brace and figuring out what my knee could comfortably tolerate. In the second game I learned more about what movements my knee could handle with this brace - I did much better. And by the third game I was close to my old self but was still cautious out of safety. I would not have been able to play without wearing the brace. This did an good job of stabilizing both sides of my knee joint. It is both easy to adjust and lightweight. The neoprene maintained its shape and the X crossing straps supported my kneecap. I wear the brace now for longer and longer periods of time for everyday activities and walking and find it's very comfortable. Eventually I might get a Don Joy, Bledsoe or Breg high end knee brace. This McDavid is a very good brace and a good value. If you need a brace for both lateral and medial stability that has patella support, this will do a fine job. I can wear this comfortably for hours at work. This should help my knee heal quickly as long as I don't aggravate it on the court. If you want to use it to play sports in then go down a size because it will loosen up with a week or two of use. If you plan to use it for long term wear then make sure you get the recommended size according to the sizing chart. Overall I'm very satisfied with the brace. It had a little bit of everything for the knee so get it. This should be considered if you have mild to moderate knee problems. I would not recommend if you have a torn ACL or significant osteoarthritis and you're trying to also play sports. You will most likely need a more high end brace for the job. The crossing straps on this model really make this a worth while functional brace.
