To a lot of people, me included, comfy and heels just don't belong in the same sentence. I can't wear "killer heels" due to having very painful arthritis in one foot.
I can wear heels of up to 1.5 inches as long as I don't have to walk a lot, so I joined this thread to see if anyone could suggest some comfortable but elegant shoes (with a slight heel)
I'm afraid I really dislike the clumpy Esska shoes shown on here. They are anything but elegant.
That said, I agree that flats wouldn't look right with the OP's dress.
