Any SPD compatible shoe with a flat sole will work just as well if you don't install any cleats and give you the option to go clipless later if you wish. I have a pair of DMT shoes like this and even with a cleat installed they allow you to walk normally. I bought them a few years ago on closeout for about $25. I use them on my touring bike with SPD type pedals but they would also work with regular pedals even with the cleats I have. Gives me the best of both worlds
