    • Good support for short distance walking and running
Size: XX-Large
Great knee brace for walking and short distance running. Comfortable and stays in place. Gives decent support. I’m fairly short and muscular and this brace offers the right amount of support for my lower center of gravity. Had to go through XXL, and XL before settling on L. I found the size recommendation accurate. ... show more

    • New knee brace
Size: X-Large
Your measurement at the knee made it a little tight. But I'm slowly getting it broke in. But there's not a whole lot of adjustment. Of course knowing every person is different as far as measurements go. But it's doing what it's supposed to do and I like it.

    • Supportive and comfortable knee brace
Size: X-Large
This knee brace provides very good support without feeling overly bulky. The hinged design helps stabilize the knee and the straps make it easy to adjust the fit. I was impressed with how secure it feels once properly adjusted. It gives extra confidence during movement while still allowing a reasonable range of motion. The materials also feel durable and well made. Overall, a solid option if you are looking for additional knee support and stability. After few hours you can feel some itching. ... show more

    • Best brace I've ever owned.
Size: XX-Large
I have one knee that needed a replacement in 1990. They advised me to wait till I was older. Over the years I have purchased numerous knee braces for this knee with varying results. Recently, my other knee began giving me problems and I once again found myself in search of a solid knee brace. I probably own more knee braces than WalMart and CVS combined! This brace is it!! It fits, it is very sturdy and I can wear it all day. I work in the yard a lot and this brace allows me to do so without pain. I bought one for each knee and am so very pleased with the fit (does not slide) and the sturdiness. I wish I had found this brace years ago. I thought the cost was reasonable. To be honest, when you've searched as long as I have, price becomes secondary to being able to wear it and have it do what I need it to do. It is super easy to put on with just a couple of adjustments. Kuddos for design, function and fit! ... show more

    • Painful brace setup
Size: XX-Large
Thought I would upgrade from the amazon alphabet company braces. Good reviews etc. Not sure if mine was actually defective but it was painful to wear. I even went a size over as I sort of sat at the top end of a range. The left brace bit into my knee.. didnt matter how I tightened it etc. Even sitting, painful. I hope it was just a flaw in what I got but I need a working brace and cant trust this one. ... show more

    • Heavy and bulky
Size: Medium
Not a replacement for a true functional brace. Heavy and bulky. Would probably help with knee pain and instability, but you will need to tighten brace so much it almost hurts. I returned mine because it was not what i needed, it came in the wring bag and had someones pet fur on it so I'm guessing it came to me used. ... show more
