So went by the Pony last night since it was on my way. Tried on some Sidi's, 46 was too snug and I had dress socks on, 47 was a little wider too. So this morning I ordered the red Corsas! Thanks for everyone's input. It seems like people like a lot of different boots, but everyone I talked to that had the Sidi's was absolutely in love with them. That's worth a few extra $$$, hopefully these will last me quite a few years. Heck, maybe I won't even have to crash-test them.
