I worry about that too... my foot is a bit wide in front but not at the heel. But it seems like regardless of whether I wear a man's shoe (my very old Sidi Bullets) or women's (the newer Dominator 5's), I need to wear thick socks (Defeet Cush 3D socks) in order to get a good fit. Size 41's are just a tiny bit too short (I can feel the front of the shoe with my big toe) and in 41.5's, my foot slides all over the place.

I think you're right. I've always used SPD's on my mtb but they're the ones that come with a platform. For the roadbike I got some inexpensive Shimano pedals without platforms.
