Shannon I like them (alot) and I don't think two pairs is too many.. however I tend to agree with somen of the other comments. These, I think, are a lower heel? So I do see an advantage in having a lower heeled pair. The are similar, but different enough to my eye. I am not really helping but I would probably take a moment in your closet and have a good look and think about how your would wear them, what you would wear them with, and how often you think they would be worn. I am finding that being more intentional about my purchasing is saving me from not only making mistakes, but also from buying fab things that end of not getting worn enough.
EDIT: Just looked at the loafer! I am just wiping the drool from my mouth (sorry that's gross) - stunning and a very different shoe to your Docs. I think these may be a better choice.
