Sizing is so weird. My husband just bought me size 41 Sidi's for Christmas (my Shimanos are 41s) and they were *way* too small. I wear a 9, 9-1/2 or 10 in street shoes, depending on the shoe. The 41.5 Sidi fit but was snug, and I knew that once I put a different insole in there, they'd be too small. The 42 feels great though.
