I got the dual sided pedal / SPD clip on one side, flat on the other
Shimano 530 I think.

Shoes,, best to try on for a good fit.
I like my Shimano shoes, but my preference came with "they fit real well"

Safe, yes
Takes some training your brain to remember you always have to unclip, one side to touch the ground before stopping.
It's a " self teacher"...... fall over a few times, you learn, as most of us did.

New to clipless pedals
