Properly fitted hard shell pads should center the shell directly over your kneecap with the leg both straight and bent at 90 degrees. The shell should cover the entire kneecap with a small margin around all edges. Straps should be snug enough that the pad doesn't shift when you walk aggressively or simulate a fall, but not so tight that they restrict circulation or cause discomfort. Test the fit by doing deep knee bends—the shell should stay centered without riding up, rotating, or pressing into the back of your knee. If the shell gaps significantly when your leg is straight or presses hard when bent, the articulation or sizing is wrong.
