Despite is being a major violation of HTFU, I'll stick to my cycling shoes for distances everyone here would laugh at.
I wish I had just gone with MTB shoes to start and that was an option I considered. Flats for a long ride isn't a viable option for me due to some foot issues that leave me with intense pain. Guess I'll just stick with the a530s. Really MTB shoes will be the option I would actually want.
Thanks for replies
