2 Questions wanting to know ?

Umm , my first question is that after running a mile on a empty stomach
( wake up and run a mile ) and then eating protein/breakfast, what would
happen ?

And my second question is that is it better to run miles with running shoes?
I'm getting under 8 minutes with vans :S ,

 

I tend to have a protein shake before I go running in the morning, when I'm done I come home to a nice healthy breakfast before I start the day. It all depends on whether you can run on an empty stomach, and not get tired. Many people say that running before breakfast helps reduce weight quicker, and I totally agree.

Yes, always train in runners. They are designed specifically for training/sports.

 

It'll feel lighter and easier to run

and I'm surprised you haven't completely destroyed your ankles yet >> are they the big kind of Vans or the smaller ones?
