Clips and straps only really work if you tighten down the strap pretty effing tight. It will still be inferior to clipless, but passably good.
However, if you tighten the strap, good luck when your front wheel slips out from under you in a corner on wet pavement. Mine did 3 days ago, and I managed to put my foot down and stay upright (I use SPD clipless). I was astonished that I clipped out so effing fast, instinctively. Not the first time, either.

BTW, somebody tell me WTF diffference "high quality" straps make. I only ever had cheapos. You tighten them, they stay that way. That's about what I expect from any strap... What else can a $100 leather double hipster jewel do?
