Do you have an injury? Knees over toes exercises can do wonders for rehab. From a form perspective, it also helps to avoid heel-striking.
Not heel striking. I wear thin shoes with no padding (barefoot style) so I couldn't even if I wanted to.
It could be some kind of form issue, I guess.
It's a mystery.
if your form is wrong, it totally could result of extra impact on knee. Its better to run with padding than do not run at all.

few points to check:
* make sure you strike under your center of gravity and not in front of it
* even you don't do heel striking, make sure your feet is almost flat, this will engage bunch of muscles for impact ammortization.
* make sure you don't jump up and down, but more like your hips are floating forward in straight line
