Actually wearing flip--flops is really dangerous on a two wheeled motorbike. They offer no ankle protection, and you run the risk of slipping and having the flip-flop wrenched off your foot if you step on loose gravel, or a slippery surface like painted road arrows, construction plates and so on. Your foot also lacks protection from flying debris such as gravel, glass, or insects.
This is what happened to a woman wearing canvas shoes. it would be no different in flip-flops.
