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.

No injury I'm aware of. I've never been a runner, trying to start in my 60's. Starting with c25k plan, so it's mostly walking with short bursts of very slow running. No pain during run, but for a week afterward get pain in left kneecap whenever I go up stairs. Everything I've read about kneecap pain is not good.

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.

> It could be some kind of form issue, I guess.

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
