Joy, I hadn't thought of ordering the Fluevogs--that's a possibility! I tried them on in store--twice, in fact--and I didn't want to go back and try them again unless I was pretty sure I wanted to get them.
Here's where I'm at, though. I kept the Dune Londons but did not yet wear them. I saw another pair, called Peppie, by the same brand and have ordered them. I have kind of high hopes for them; they have a lower heel and taller shaft than the Parnell and an almond rather than rounded toe. They are a little more expensive, but just over $100 (from Dune London, where I found my size; they are less at another place I found them, but not in my size), so still a bargain. Part of my original hesitation on the Fluevogs was that they are so nice. As in, the leather is so soft and nice, I would be afraid of ruining them. And I was really looking for a lower heel, although the heel could work for me; it's not a deal-breaker.
eta: Oh, and I hear you on Clarks. I'm that way with Eccos. Almost always between sizes. Though my recent sneakers from them seem to be the right size, despite the annoying break-in period that they are requiring!
