In reply to UKC Gear:
It's interesting you say you wear your street shoe size - I haven't tried the Flagship (difficult to justify for the kind of routes I typically find myself on) - but I did try the VCS in Outside and James T was saying that they come up very large.
I find the same as you, and my "ideal" fit is close to my street shoe size - I can only assume James likes his shoes very tight, or that the bigger sizes (I think he has size 11) come up much larger.
