Even though I was sized at 41.5 with the "official" Sidi foot-measuring device, my Sidi Bullets are size 41 and they're a little too big for me. When I do long rides in hot weather I wear them with thick socks (Defeet Cush 3D's). While riding at night when it's cooler here, I sometimes have to add an extra insole to make them fit right.

So when I buy my next Sidis, which will most likely be road shoes, I'll probably go for size 40.5.

Good luck and enjoy your purchase!

Wow see this is weird my foot is definitely no bigger than a US 7.5 and I wear 41 Sidi. Are you talking about US sizes? I find it hard to imagine someone with a foot bigger than mine fitting into a smaller cycle shoe than I have. Hmm very bizarre.
