Great Fit - great functionality!

This knee 'brace' stays put and is great to wear while running and cycling. I have athletic thighs and expected it to slide down but it stayed put perfectly. There are grippy dots along the inside top edge that keeps it in place. It is comfortable and light weight and it isn't bulky - just a little behind the knee but it is not bothersome. I purchased this item due to a sharp pain that happens when I misstep but this device gave enough support to keep my stride in line so I can run pain-free.

Not true to size

I get this knee brace because I was having more knee pain at work and play. First off, the size chart is off. I measured myself and should have fit a medium, but that was way too small. It wouldn't even comfortably slide up over my calf, and my calves aren't that huge. Once I got a large, I started being fairly happy with it. I have less knee pain when i remember to wear it regularly during work, biking, runs. You have to wash it every so often to stop it from sliding down and bunching while wearing, as it seems to stretch out just the tiniest bit and the grippy beads pick up skin cells or something. Onceclean, it stays in place pretty well. You'd probably wash it regularly anyway if you are sweating while wearing it since it is synthetic. Makes me feel secure and have less pain after a long day of chainsawing or biking.

Should be more breathable when wearing for days

4 years ago

I’ve been using this product for quite some time for long day hikes, it’s very good supporting my knees. I recently did multi days backpacking wearing it longer than my usual day hikes. The elastic beads gave me blisters on the 3rd day of my backpacking trip.

keeps me moving

4 years ago

bought this a month ago to try and help with an achy knee on hikes and rides and it is amazing. nice support to help keep me on the trail. would recommend to anyone. stays in place well. With the exception of a few miles of running sometimes it will start to slide down. I found it true to the sizing chart.

Major Slip

3 years ago

I've been using these for 2 years, trekking through Ecuador, skiing different hemispheres, and trail running. They are a pain in the ***. But they help. I got them for knee pain and they do help when they stay up, but I need to pull them up constantly. I tried shaving my legs to see if that would help them stay up, no luck. I just pull them up all the time

great support, irritated back of knee

2 years ago

Support was ideal for a hike. However, with each bend of knee up a mountain the back of the knee became more and more irritated. Unfortunate because otherwise great overall knee support going downhill.

Excellent short term support.

1 year ago

Stabilizedf my knee perfectly for short term use to be able to stretch my legs properly. I had to learn a gluteus stretch to begin to stretch the long muscles above and below the knee. Since then I discovered that magnesium malate is a game changer for relaxing overly sore muscles, also making it easier to stretch. I'm not a fan of braces for long term as I don't want to weaken balancing and stabilizing muscles to become dependent on braces to keep going.

Had Doubts but Totally Sold

Had my doubts about the comfort, but I’m totally sold. Comfortable fit, no chafing. Even while sweating was still comfortable. have worn as long as 2-3 hours.

A good knee support

4 years ago

The best knee support I have found that is not custom made. Provides good support and stays in place longer than other brands. It is comfortable and easy to care for. Air drying after washing it seems to help it stay in place. better.

Great support for kneee

4 years ago

Got this in a size medium at the suggestion of my doctor after a knee injury. I've used it for cycling and trail riding, and haven't had any issues with slippage. Fit great and gave me the support I needed until my knee fully recovered.
