Helped my son
We bought these for our son who plays football and loves to go skiing also during the winter. He injured his knee last year and had avoided sports as his knee would buckle. According to the orthopedic doctor he damaged his meniscus and partially tore his MCL/ACl so we got these through DME-Direct. He is 6'2" tall so I got him the Standard length in the combined instability strapping to give him more protection. He used it last week on a ski trip and it saved his knee he said.

Didn't fit me...but
It didn't fit my leg - all of my measurements were not within the size I chose. DME-Direct was great - they took back the brace AND got me into another brace that fits my leg size and shape perfectly. Thank you!

Protected now and more active
Brace fits well. I have a bad knee and this brace has allowed me to be more active and more protected. It is very sturdy. I bought the short calf length style ACL fr my right knee and I'm very pleased with the customer service and the product.

Replacement for old braces
5/5 stars. Replaced my son's old braces with a new pair for this football season. Bought through DME-Direct and they arrived the next day - surprisingly faster than through Amazon. Very pleased!

Good purchase to protect my son...
I needed to get braces for my son who plays football and read plenty of reviews for Donjoy armour knee brace and finally got him a pair as they were on a good sale here. The price was fair and the shipping was very fast - our order arrived a couple of days later. He has been wearing them at practice now everyday and reports thay are helping to protect his knees during practice and scrimmagees. Recommended

High school lineman
Bought these for my son who plays on the line in high school. Many teams were "chop blocking" illegally and we were worried about his knees. Other than custom braces at $1000 or more per leg these seemed the next best option according to my research.Still a pretty penny to pay...about $1000 total. The actual braces do their job and for the most part are comfortable but I wish more so. My son complains about the braces pinching in places. He used the sleeves that were sent too, and those help, though they are black and get hot if playing in any weather greater than 75 degrees. He has gotten used to running in the braces but they are still a bit cumbersome.They are a little tricky to get on. Lots of straps and such. He struggled at first but is good at it now.I suggest wearing a smaller girdle with these, just to lessen the bulk. My son had one girdle with more padding that just fit too tight with these. Then the football pants go on it gets tight quick.Overall customer service was great. They work with you and aim to please. Would purchase from this company again. Oh, we sized my son for a large but they were too tight. Went to an XL and they work fine but FYI according to his measurements he should have been in a Large.

Donjoy Armor Action for football
I've been using my Armor Action now for a week with football practice and it has been fitting great underneath my uniform. I haven't needed to adjust it that much and it has saved my knees once or twice already. Thanks.
