Review: Excellent design and quality - I've tried a lot of different brands. I hike take moderate hikes regularly, have moderate arthritis, am old.(73) These are thin, yet provide the right amount of support- not too much which for me can actually increase pain due to lack smooth interaction between all areas of the knee. They are very durable. Worth the price!
Review: AMAZING SUPPORT......HIGHLY RECOMMEND - Was a bit hesitant when ordering these. You never know what you are going to get with these and everyone is shaped so differently. But was so pleasantly surprised. LOVE them. I was preparing for a 2wk European British Isle tour.......LOTS of walking. I wanted something that would be great support without causing irritation. Just a nice support. I searched for 2 weeks and poured over reviews. And settled on these. I ordered for both knees so I would have support for both even though I technically only have 1 bad knee. I am so glad I did. They worked great!!! 2 years ago, I did a Tour of Italy and ordered a neoprene one for just the bad knee. That brace was like walking through hell. It was thick, bulky and not breathable causing irritation and blisters. I didn't want to repeat that again. I am now back from my tour and so glad I took these. I wore them daily....even on the airplane in place of my compression socks. My knees never gave way, didn't have the severe pain I was expecting......it was a nice trip all due to having the support I needed. Since getting home, I haven't worn them and I honestly kinda miss them. I didn't realize how much a little support goes a long way. I didn't realize how much support they provided to my weak knee until I stopped wearing them. So needless to say, even though I am home, when I go out......yep, I am wearing it. I really liked the placement of the anti-slip grips on the inside of the braces. I was concerned with irritation but never had an issue with that. There are anti-slip grips around the knee and along the upper and lower bands. Some customers mentioned slippage. Please note.....when you pull the brace on, the upper and lower bands have to be completed flat against the leg or you will have slippage. It created almost like seal of sorts. The few times I had issues with slippage, I could see that the upper band around the thigh had a spot that wasn't flat against the skin. Once corrected, slippage wasn't a problem. I also highly recommend ordering a size up. Had I gone with the recommended size, they would have never worked. Some customers also mentioned seams coming apart. I did notice that the seams in the back of the brace starting to separate. But I also noticed it is separating from being pulling on from the top of the brace. Now I pull it on with the sides collected together instead of just pulling from the top. I highly recommend these braces and will definitely be repurchasing them.

### ⭐⭐⭐⭐ Very supportive brace
*by L***A on October 6, 2025*

This knee brace is very supportive and easy to put on/off. The only reason I didn't give it 5 stars is because the top band feels quite tight after awhile so I need to remove it.
