Ha ha, well the two previously frost bitten ones are pretty gnarly looking anyway, so She will probably only give me credit for 8!
I guess one reason for my uncertainty is that, other than the Koflach plastics just in training, I have only used the Nepal Extreme. I'd guess this would be similar to the Evo in terms of warmth etc. or are the Evos warmer than the NEs? It seems to me that going from them to something like a Baruntse is a big difference in boot type and I do wonder if I'm looking at "too much boot" for what I'm realistically going to be doing? With a grand total experience of N=1 I obviously don't have much to go on here, but I can say that my feet were cold in the Nepal Extremes, I was using a chemical heating pad in them (totally useless IMHO), yet it was only around -15C ish (give or take a cocktail umbrella or two). I like to kit up for -20C. I can imagine the hike out may be a little more awkward, but otherwise would a boot like the Baruntse have any other negatives I'd need to consider over something like the EVO when used in warmer conditions? Or are they simply similar to my plastics in that regard? When I say my feet were "cold" they weren't dangerously so, and the boots were frozen when I put them on which wouldn't have done any favours, but I get cold feet and did notice it. If there are no serious disadvantages, and my feet run cold, it seems like a no-brainer to simply shut up, pay my money, get a warm boot and be done with it.
As you see, I have seemingly endless stupid questions at my immediate disposal.
