It's a bit like walking in slippers all day. They are only supposed to be used for short shopping trips. At least the cambons are. I wore them to work a lot because I didn't want to walk around barefoot.
I just got the black/black patent cambons the other day. I needed a pair of shoes that were nice and comfy for walking around campus all day. They're REALLY comfortable and true to size (for me, at least). My mom has the ones with the contrasting cap toe color and the CC's just stitched on..those run true to size for her too.
