First off what knee sleeves DON’T do. They don’t support the knee or meniscus, they are meant to keep the joint warm and increase blood flow not to support the knee in anyway•
They may prevent injuries.. but if your knees are collapsing in on your squat, knee sleeves aren’t going to change this.•
What they DO: Is provide compression to the knee joint which provides more biofeedback/proprioception•
They also provide increased blood flow to the knee joint, by keeping the knee warmer.•
The short answer should you be wearing knee sleeves?? If you are in a competitive lifting sport maybe, if not then save the money and get your form checked out!
