My brown calf semi-brogues arrived today, and lucky me, they seem to fit. (I say "seem" because I wore a pair of SmartWool cycling socks to work today (don't ask) which have a slightly thicker heel than my normal wool, over-the-calf socks, so I can't be certain that they maybe won't be a little loose with normal socks. Still, even if they are, it would only be a tad bit, which I think I can live with.)
FWIW, I ordered a UK8, but since I have no idea what my normal shoe size is, I guess that's not worth too much. In running shoes, I pretty consistently wear a US9.5, but in non-running shoes, I'm all over the map: a pair of Tod's in 9, a pair of Peluso for To Boot NY in 8.5, a pair of Bruno Maglis in 8, and a pair of Pradas in 7(! but I picked these up in Florence, so I have no idea what the 7 is supposed to mean; there's no European size for comparison, unfortunately).
