Ken HanleyMy KneeFlex got me back in the gym doing the things I thought I would never do again. It helps with my knee pain and gives me the confidence that my knee is stable enough to push a little harder during workouts.

Marcus JohnsonAfter dealing with knee pain every day, from the moment I step out of bed in the morning, it’s been a pleasure to use something that actually helps. I put my KneeFlex on in the morning and wear it throughout the day. I take it off at night and sleep a lot better knowing I don’t have a day of knee pain waiting for me.

Frequently Asked Questions

What is the purpose of KneeFlex?
KneeFlex offers a comfortable way to get compression on the knee. This allows for more stability and increased blood circulation in the area. This can be useful for active exercise or just daily use.
What is KneeFlex made out of?
KneeFlex is made out of nylon and spandex, which means it will conform to your knee with the proper amount of compression. The material is also moisture wicking, breathable and smell proof. The brace also consists of a silicon pad and double-sided metal spring brackets to offer more stability!
What makes KneeFlex special?
Spring knee support technology: An anatomically contoured silicone pad surrounds the kneecap. It effectively disperses pressure allowing your knee to feel secure but also unimpeded and free.
How do I choose the right size?
Simply measure the diameter of your lower thigh area and the area of your leg below your knee.
If you can’t measure, you can go by your weight. The KneeFlex sleeve is flexible so it should conform to
your knee even if the size isn’t an exact match..
