Ive recently started lifting heavier weights at the gym and had noticed my knees were getting sore and sometimes bruised. Since trying these knee braces over the last couple of work outs, I've noticed no more pain or bruising. The compression sleeves fit comfortably and dont slide around with the gel type backing at the top holding them in place for the full work out and treadmill run at the end. They are breathable and don't gather at the back or sides when bending the knee so you dont really notice they are on, except for the support they provide. I wish I had grabbed some sooner, and from the quality of the sleeves, Im sure these will last for some time. Overall I am very happy with this purchase!
