Thanks for the advice. I've been trying to experiment with foot position and trying to flatten my foot as I ride. But after a while my mind wanders and I go back having my heel up. I guess it's just something I'll have to get used to with practice. It makes sense, actually, it's the general rule of having the weight on the ball of your foot works the calves and can damage the knee, but when you have your weight on your heel (similar to riding with your heel down), it works butt and thighs. That would explain why my calves are beautifully toned, but my thighs are...well, not.

But CR400, you are saying that while spinning its ok to point your foot slightly?

And, the cute guy asked if I was ok, but didn't actually come over (I guess that says something about him). And I'm not one to play damsel in distress and lie there until he helps me. I got up, laughed and told him I was ok (even though there was a gash on my leg) and eventually rode off.
