I am also finding that keeping my core temp higher is helping. I find staying on the warmer side of ideal seems to work better at keeping both my hands and feet warm.

For me the new mitts are working well to keep that heat from bleeding off faster than my hands can make it. I was pleasantly surprised when I realized my fingers were not going numb. I do have to discipline myself to not remove them unless absolutely necessary. The lobster claw liners do make it easier to articulate. I am able to work all my zips and tiny buckles on my clothing and daypack. I also converted my winter boots to a barrel lock system so I don't have to tie or retie them with bare hands.
