Apparently my circulation has become more efficient at keeping my core warm over the decades, or my brain has judged my extremities more dispensable, or something. So, for anything below about 55 degrees F (or maybe 50 degrees if the day isn't particularly humid), I use deerskin mittens with wool mitten liners. I'm glad my winter/errands bike has GripShifters, so shifting is no problem.
For footwear, I have hightop Mavic winter shoes that I found on closeout. Still expensive, but their insulation is excellent, and they fit me the best of all my shoes, biking and otherwise.
The other winter shoes I used in the past were marketed as police bike shoes. One pair was Diadora and the other Sidi. Both were much wider than the racing shoes from the same companies.
[Edit: the Pro's Closet seems to have a number of Mavic shoes on closeout. Might be worth checking, whether you're looking for winter shoes or others.]
