/ Nepal Evo's and Yeti gaiters-6500m?
Yeh, that's the problem. It's probably more about how high you are camping, rather than the highest point you'll touch.
If it's a popular peak (Mera?) then you can have a long summit day and camp relatively low. If it's a first ascent of a 6500m peak then you might need to camp quite high - and still have a long summit day.
Karakoram midday in August will be hot. TienShan 6500m = cold. Nepal in November will be cold. So you probably need to be a bit more specific about what you're doing. If in doubt, use modern doubles.
My toes were absolutely freezing even at 5000m in Tien Shan. It wasn't that cold but I was horribly dehydrated, had been on the move for 20 hours straight, it was in the middle of the night and my lunch and dinner had consisted of a pulsin bar. Make sure you plan for contingencies is my advice.
And to add, Yeti gaiters give bugger-all added warmth. They lack insulation all over, but particularly under the sole where a lot of heat escapes. They might stop the Nepals getting wet from snow on the outside though.
The plus side for Vegas is you can put the inners in you sleeping bag at night to keep them warm and they don't take up much room, down side is they hurt like hell to walk in and they are heavy and they made my feet sweat.
I used Nepal evo boots with yeti gaiters at altitude recently and I had no issues with cold feet. I did however have a set of custom made insoles made so to spread my full weight across my whole foot and not cause cold spots. I also used a good sock combination with well fitting boots, changing my socks for a brand new pair for summit day. The only real down side that I found was I had trouble keeping them dry and they were a pain to put in my bag at night to keep warm.
If you want to use your Nepal evos why not try them with 40below neoprene gaiters if you are worried about cold feet.
thanks to all, plenty to think about, probably off to e bay to find some unloved doubles or similar. Ps Size 44 if anyone has anything of interest.
