I have extraordinarily fussy feet so consider me an outlier on the comfort spectrum. If the Sam Edelman pumps work for you, I highly recommend them. They look absolutely gorgeous on. I think they would compliment your dainty frame very nicely. The problem I had with them is the same problem I always have: The material was stiff and rubbed my bony feet.
The shoes I had up for grabs are on their way to Angie unfortunately. It's a bit complicated: According to the size conversions on Endless.com, a 37 was supposed to be the equivalent of a size 6-6.5. They ended up being too big for me, which sort of made sense since I am often between a 36 and 37. Since Laura is a pretty consistent 37 (and US size 7), I sent them to her, but she found them too big as well! OTOH, Angie is a US 6.5 and has the same pumps in grey, and they fit her well. I'm curious to see if they fit Angie differently than her grey ones. I'm sure no one actually followed what I just wrote--I can't even follow it! They would have been great in the right size though, but unfortunately they are mostly sold out.
The Clarks you posted don't look loaferish at all...although I actually don't think there is anything wrong with loafers and dress pants.
