TroadlopMen's Running Shoes Non Slip

My goal is to run 45 mph. can these shoes handle this much speed?

i I got a size 12 but not wide enough. How do i get a wider size?

I wear a size 11.5 what size do I order

Can you use these like regular running shoes. What I mean is for running 50 or more miles a week on pavement, workouts on the track, and some trails?
