"For feet, I buy my winter hiking and ski boots about a size too large so I can use three sock layers — first a thin polypropylene inner sock, medium sock and then a heavier sock. I find the Keen boot brand offers more toe space. For ski boots: after getting the most insulated ski boots I can find, I often use an overboot (available at AMH). And if it’s REALLY cold, I’ll insert the toe chemical warmers too. 

I have a friend who is really athletic and can leave guys half his age in the dust, but he has ACUTE Raynaud’s.  He has special footgear (don't recall the brand) and actually uses electric (battery-powered) gloves that are very pricey. 

In addition to your Seinfeld (Elaine) type weird dancing, food is most important as you know. Heat from within — fatty foods. On your next cold journey, try taking along some smoked or cooked salmon if you can get it."
