re: Running advice requested for new runner (updated with new shoes!)

Get on an actual plan. Like a half marathon training guide. It will build you up at a challenging, but acceptable pace. Even if you don't plan to do a race or even reach those distances. If you ever feel "pain", back off until you don't feel it. Like someone else said, you may not have the proper muscle support yet and you can hurt yourself.

I get a weird feeling in my left knee when I reach my limit. Comes at about 3 miles when I'm not in shape. But after slowly building up my endurance, I've gotten up to 8 miles without that pain showing up. But I haven't run in some time, so I bet if I went out to run 3 miles, I'd likely get that pain again.

Another thing is if you have the time and feel good, don't let your brain talk you out of keeping going. Maybe I'm just a lazy SOB, but I can talk myself out of that last mile pretty easily and I later kick myself when I realize how much I had left in the tank. It's only slowing down your progress.
