That's what I've been trying That's what I've been trying to say, Jason, but I don't think anyone is buying it. I find that overbending my knees puts too much load on my calves and leaves me with calf tightness the next day, whereas if I find the right balance, I don't have that problem. (When I run in huaraches--like 5 or 6 times since ever--I always find myself bending my knees more so than when I am running barefoot. The next day, I'm feeling it.) That's why it's so important to bend the knees in moderation, a little at a time, until you can work up to bending them more, and even then, I don't think we need to go crazy about it. Just bend them enough to keep your heels from striking, run gently, and not push off.
