I used to practice pedal-striking, until I dumped my roommate's Motobecane in 1981. My hip hurt for a while iir.

Later, I discovered plastic pedals, and their magic ability to not dig as hard since they didn't attach themselves so violently to the pavement, but glided on it.

Shorter cranks and pedals can be the answer. Schwinn's cranks were short and their bb's very high, to allow for the very wide pedals that were fitted to their electroforged road bikes.

Last time I went down from pedal-strike, I was riding a new-old Mondonico-built Masi Nuova Strada, with a low bb, 175mm cranks, a triple-length spindle and 2-sided SPD pedals.
I took a left-hand intersection corner wide, to set an example for the other riders who so often blindly cut the corner in front of possible cross-traffic.
I had to lean further to square the corner, and bang, I went down at low speed instantly, and just as fast got back on the bike with minimal rash and only some torn bar tape to show for it.

I recently saw an approaching Cervelo rider almost lose it to pedal strike in a bumpy right-hander, woulda hurt on that coarse pave! I passed in the opposite direction, preparing for my own left turn, and heard the strike as soon as I saw the guy approaching from the right-hand corner he was strafing. It really got my attention!
