I am willing to bet cold, hard cash (at least a $1), that Gary, Ron and myself all have smartwool or bridgedale wool socks. You are just one genetically lucky dog to have warm toasty toes! Damn, I'm jealous. Would save me a lot of ski moola 
OK, when someone is willing to put down THAT kind of cash, I know I'm about to lose.? Maybe the difference is just that I've got standard thick liners in my boots that provide more insulation than the high performance thin liners that y'all have.?
I'm going to be a bit humiliated to have Lynn and her custom liners skiing circles around me, but I guess at some point all parts of the male ego just need to crumble.? Hopefully she will be a lady about it and not 'in my face' too much.
On a serious note, a question probably for Lynn.? What is the path of blood flow into and out of the foot.? I know the femoral (sp?) artery feeds the leg, what goes into the foot.? I would think having a pocket warmer placed over that artery (if it's close to the surface like the wrist) would effectively warm the entire foot as the warmed blood is carried throughout the foot?
