I know it when my knees or other part of my anatomy starts hurting AND the shoes have gone a few hundred kilometers...

Which doesn't help you here, I know.

It wouldn't really show, I'm afraid...

Although the shoes are a prime suspect for your knee pain, I would primarily suspect that the quick increase in your running volume might be at fault. Going from zero to three runs in a week might be a bit much for your knees... You might want to give them a chance, include more walking, or something like that... But this is very unscientific.
