If I want to walk around (eg. commuting), I do it on a bike built for it with flat pedals and just wear shoes made for walking. If I am fortunate enough to be able to travel by bike, I'll just pack walking shoes.
MTB SPD shoes seem neither here nor there. Ideal option for a MTB or gravel bike, sure.
So would you feel better if the OP got single-sided SPD road pedals and a 2-hole "touring" shoe? Then they wouldn't be using "MTB" pedals or shoes.
