I am 6'2" with a 32" inseam, and these did not provide enough coverage for my taste. They end about 4" short of my shoe, with the hard-shell plate only covering part of the front of my leg, with almost no coverage of any kind on the sides below the knee.
The knee cup is very deep and forms a great pocket for your knee when it is bent at 90 degrees. The way these are sewn, however, keeps them from articulating much at all, making them difficult to pedal in, and forget about walking. So when you are in the attack position on your bike they fit pretty well, but otherwise not so much. I really wanted to like these, and wore them for several hours around the house, and even riding the bike out in my street a bit, but the fit never got any better. I had to keep them uncomfortably tight to keep them from slipping and rotating, probably because they have no silicone or elastic against the skin to prevent this.
A BIG plus of these is that they should be relatively cool on hot days. They also look pretty good, and are probably all you need for the bike park. The price isn't bad for what you get.
