> Any reputable running clinic will teach you to make contact with the ground at the middle of your foot with a slightly bent knee.

Honestly, I'm shocked anyone lands heel first anyway. I was never a runner.. but even as a youth, I didn't do this. It was obvious what felt good, and what felt good was engaging the knee and ankle, using them as springs, etc etc.

I don't understand why people need to be taught how to run. Very strange to me.
