They are the only knee pads I've owned since getting back into MX, but overall happy with them. Ditto on the comment about larges calves, though. I'm an avid mountain bike rider and have the legs that result from all the climbing. Accordingly, strapping my tech 8's takes a little work, but it can be done securely. They still look like new, so they seem to be built quite well. I've also shattered my knee cap (on mountain bike), and it is shaped and moves rather strangely, But the knee caps move along without restriction. I should probably be in braces, but seem to be managing with the fox stuff.
