How cold does it have to be to stop you?

I don't ride if it's below about 10F, if I can help it. I hate that feeling of your eyes starting to freeze shut and your nostril hairs freezing together, but really the show stopper is that I can't keep my feet warm even in 3 pairs of socks + booties. Also as somebody else said, your bike doesn't actually work that well in super-cold temps unless you switch to special lube, etc., so you end up with about 2 functional gears and pedaling is really hard.

Speaking of cold feet, does anybody have good women's winter cycling shoes to recommend? The Sidi Diablos look good, but they only go down to 40, and I'm a 37. I'd rather not switch to platform pedals and boots (though boots could be useful when trudging through icy snow pushing my bike when I wimp out), but last winter was SO COLD, I think I lucked out in not getting frostbite on my toes. This winter I've vowed to find footgear that works in all conditions.
